How to independently replace a slate roof with corrugated board. Technology for replacing slate with corrugated board Replacing slate with corrugated board without replacing the crate

Before covering the roof with corrugated board, it is necessary to dismantle the previous coating. It is important to start doing this on days when rain is not expected. It is equally important to do this in almost calm weather. But even if weather forecasts promise dry, windless weather, it is better to stock up on film, which you can close the attic space just in case.

When removing a slate coating, you will need the following materials and tools:

  • nail puller;
  • several wooden bars;
  • ropes;
  • a pair of strong hooks.

You will need all these materials for the efficient and safe work of dismantling and lowering the old coating from the roof. We carry out the work in the reverse order of installation, that is, you need to start dismantling the coating from the ridge. Next, proceed to the removal of the upper rows of slate. So sequentially remove all the rows, reaching the cornice overhang. Roofing nails are removed with a nail puller, under which they put wooden block or a piece of board for the convenience of performing work. When the crate is completely bare, it is inspected and, if necessary, the exited and rotten sections of the structure are replaced.

To lower the slate with your own hands from the roof, use the holes in the material that remained after the roofing nails. Hooks are inserted into these holes, and wooden blocks are placed under them to facilitate sliding.

Attention! Lowering slate sheets on ropes alone without using hooks is much more dangerous.

It is better to change slate for corrugated board not immediately on the entire roof, but in separate sections. For example, you can first dismantle the slate from one slope and lay a profiled flooring on it, and then work on another slope. So you will be insured against weather surprises.

Rafter system repair

If the roof is being replaced, then before that it is necessary to check the integrity and condition of the old truss system. It is important that the rafter system meets the requirements of reliability and safety. It is necessary to inspect all rafter legs. They should not be damaged by insects, cracks and rotten areas.

If worn rafters are identified, they must be replaced with new elements that are treated with antiseptic impregnations and fire retardants. Before replacing the slate with a new coating, you need to check the evenness of the slopes. To do this, do the following:

  1. Screws are screwed in the corners of the slope so that their hats are a couple of centimeters higher than the rafters.
  2. We pull the cords diagonally across the slopes. You can also use a level to check the evenness of the surface and identify the presence of protrusions and recesses.
  3. If at the point of intersection the cords barely touch each other, then the slopes are perfectly even.
  4. Otherwise, it is necessary to carry out measures to level the roof slopes. For this use edged board, which is attached to the beam by means of bolts.
  5. After leveling the extreme rafters, they can be used as beacons and check the evenness of the rest of the rafter system.

Small irregularities in the roof can be leveled with an edged board. And those elements that are completely worn out are replaced with new, treated with special compounds. Revision and repair of the roof truss system can be done independently if you have minimal experience in the field of construction and repair.

Lathing installation

It is necessary to completely dismantle the crate if the old waterproofing has become unusable. The waterproofing carpet is attached directly to the truss system using a stapler. Strips of waterproofing material are rolled out and laid across the direction of the rafters and fastened with an overlap of 10-15 cm.

Tip: to ensure good ventilation of the under-roof space, it is necessary to lay the waterproofing carpet not tightly, but with a slight sag.

  1. First, a counter-rail is nailed to the rafters over the waterproofing. To do this, use a bar with a height of 30-40 mm. It will provide the necessary ventilation gap under the roofing.
  2. Further, a crate is stuffed across the counter-rail and the direction of the rafters. To do this, you can use a board that is fastened in increments of 30-40 cm. Work begins from the cornice overhang, moving towards the ridge. Above the ridge and along the edges of the cornice overhang, it is better to make a continuous crate.
  3. The ridge part is covered with an additional layer of waterproofing.
  4. After that, wind boards are installed.

Installation of profiled sheets

The roof is covered with a profiled sheet, lifting it along specially laid boards or bars. To facilitate climbing in an outside wave, you can drill a couple of holes for the rope. It is important to choose a place for holes, which will then be blocked by a wave of the top sheet.

Important: during the transportation of the profiled sheet, try not to damage the polymer layer, as this will contribute to the corrosion of the coating.

Installation is carried out in compliance with the following rules:

  1. Mount sheets start from the cornice overhang, having previously installed a drip.
  2. The next row of sheets should overlap the previous one by 20 cm with a roof slope of 15-45 °. And with a slope of less than 15 degrees, an overlap of 30 cm is made. The overlap of sheets adjacent in a row is 1-2 waves.
  3. For the convenience of fixing the metal profile on the crate, you can mark the rows.
  4. We fasten the corrugated board with self-tapping screws with a rubber sealing washer.
  5. After installing the profiled sheets, a ridge element is attached to the slopes. To ensure ventilation of the under-roof space, a porous sealing tape is laid under the edges of the ridge additional element. It tightly fills the corrugation of the corrugated board, protecting it from the ingress of debris and insects into the ventilation gap, but does not prevent the passage of air.

roofing requirements.

The vast majority of developers choose the material according to certain criteria, namely: price and durability. To some extent this is true, but far from effective. In order to choose the right roofing for a particular case, you must first study the requirements for such products.

  • Moisture resistance. This indicator will talk about how the product copes with the repulsion of moisture. Some materials do not have high values, so they are mainly used in arid regions.
  • Durability. The longer the life of the material, the better, this is understandable. But it is worth noting that a lot of factors affect this parameter, so it is better to look at the average value and rely on stability.
  • Sustainability. This parameter shows how effectively the material copes with the negative impact of the environment on it. This refers to precipitation, wind and other external loads.
  • Strength. The coating may have good stiffness but low strength. For effective use you need to look for something in between these qualities.
  • Tightness. Everyone knows that a lot of precipitation falls on the roof. So that they do not penetrate into the inside of the roofing cake, it is very important to create an airtight plane.

If you have access to regulatory documents, then more detailed list requirements you can find there, but this is enough to pick up quality roofing products.

Now, let's move on to the materials themselves.

Asbestos wave slate

If you are looking for something to cover the roof of a house inexpensively, then this product is just for you. However, it has some drawbacks, but let's talk about everything in order.

Asbestos slate is made from asbestos fibers and a binder mixture. The output is a quality product, with good rigidity, which is set by the waves. Their number can be from 6 to 8. Of course, you can find other types of slate, but they are unlikely to meet the requested requirements. In addition to all this, the canvas can have standard dimensions and reduced ones.

Not so long ago, the roofs of all private houses were covered with slate sheets, but what actually led this product to such a high popularity? Let's look at the advantages of asbestos slate.

  • Cheapness. This is the first thing developers look at when trying to find the cheapest way to cover a roof. The price of this material is really not high. The fact is that all the components for its production are taken from natural resources, therefore, a lot of such material can be made.
  • Strength. As already mentioned, due to the waves, the canvas is given optimal rigidity. In addition, the asbestos sheet has good strength indicators, but is very fragile.
  • Durability. The slate coating can lie on the roof for about 30-40 years without maintenance, or more than this period, if the surface is periodically cleaned of growths and the canvas is painted. The use of paint will not only protect the material from the harmful effects of the environment, but also reduce the release of asbestos dust.
  • Sun resistant and non-flammable. Due to the inclusion of non-combustible components, the material is completely resistant to open fire and ultraviolet radiation.
  • Good sound insulation performance. On the surface of the sheet there are special strips that reflect the noise coming from the outside and do not let it into the attic.

Reading the above points, you probably thought that this is an ideal material for roofing. This is true, but depending on which building they cover. Numerous studies have shown that during the operation of asbestos slate, a certain amount of harmful substances are released that adversely affect the human body. Decide this problem can be painted surface. In addition, a simple type of roof can be distinguished, and this often scares away many developers.

Ondulin

This material began to be produced in France in the 1945s, but it became widespread only after a few decades, since ordinary people after the war had no time for the selection of roofing material. In European countries, ondulin took root very well, and many developers abandoned slate and switched to it without hesitation. But the vast majority of Russians confidently abandoned bituminous slate, citing the high cost of the product.

The material is made from natural cellulose mass, which is mixed with a bituminous substance and special thickeners are added to everything. The output is a wavy material with small dimensions and weight. The color is set by adding an admixture of pigments. In its appearance, it remotely resembles asbestos slate, which is why some roofers call this product euroslate.

To date, ondulin has undergone a number of significant changes in composition and quality and is practically new material, but in the old shell. Benefits include properties such as:

  • Moisture resistance. Due to the high content of bitumen in the composition of the product, this parameter is at a very high level. The moisture coming from above has no chance to get into the roofing pie. Of course, if serious mistakes were made during installation, then water can still penetrate inside.
  • Ecological purity. Since the composition of the sheet does not contain harmful toxins, the euroslate is safe for the environment.
  • Small mass. Due to the use of natural cellulose, a thin sheet weighs practically nothing, so the canvas cannot create serious loads on the bases, and this is already an excellent reason for saving.
  • Ease of installation. Laying a rectangle small in size and mass is much easier than a heavy sheet of metal.
  • The cover can be used as an additional one. To do this, the old coating is laid wooden frame, essentially a crate. Euroslate sheets are mounted on it and the roof is ready.

Well, of course, you can not ignore the cons.

  • Canvas deformation. If a discharged crate is used as a base, then after a few seasons it will be possible to notice some deformation of the sheets. In places where they are not supported by boards, there will be indentations.
  • Flammability. Due to the large amount of bitumen that is part of the material, it burns perfectly. In connection with this feature, this product is strictly forbidden to be used on public buildings and structures.

  • Low service life. If you purchase products from well-known and high-quality manufacturers, then the average duration of use of such a canvas will be in the range from 15 to 25 years. As for fakes, the canvas will not last even 10 years.
  • Loss of saturation of pigments. Color change occurs after only a couple of years and is naturally not good.
  • Installation limitation. For the construction of such a roof, it is very important to choose optimal temperature. The fact is that bitumen becomes brittle in the cold, and in extreme heat it practically flows. Optimal conditions for mounting ondulin it is 10-20 degrees above zero.

In general, the material is good, but it is highly undesirable to use it in regions with high rainfall.

Decking

Today, profiled sheets can be compared in price with asbestos slate, so I put them in the second place of the cheapest coatings. If you immediately rejected slate and are looking for something to cover the roof of the house inexpensively, then corrugated board is the best solution.

The profiled sheet is made from rolled steel using high-quality European equipment. One sheet contains several layers. The price range of the product depends on their quantity. For example, if a sheet is covered with a protective layer and nothing else decorates it, then it will be as cheap as possible. And if polymer layers are added to it, then the price naturally rises.

It should be noted that not all polymer layers can set good quality coatings. Some of them are low quality, they will peel off the metal after a couple of seasons. In addition, during installation work, the probability of violating the integrity of this layer is significantly higher compared to the use of high-quality polymers. As you understand, the price of high-quality products is much higher, therefore, you will have to choose: for what purposes to use this coating.

At first, profiled metal sheets did not attract private developers much because of their poor quality. But over time, when production began to use new technologies, everything changed for the better. Today, this material can be safely called universal. It is used not only in the roofing industry, but throughout the construction industry.

I will not deviate far from the topic and go directly to the advantages of a profiled sheet.

  • Strength. When rolling a steel sheet, stripes remain on it, they are called waves. The higher the wave, the greater the rigidity of the sheet of metal. In addition to the wave height, it is important to pay attention to the thickness of the metal itself.
  • Does not burn. As you know from the laws of physics: metal is not a combustible material, therefore, such a coating can be used as a roof on public buildings and structures.
  • Relative cheapness. I have already spoken about price jumps a little higher. In fact, the fewer layers a sheet includes, the cheaper it costs. And of course, the price is also affected by their quality.
  • Continuous operation. Although the metal itself does not withstand prolonged exposure to moisture, it is protected by additional layers. First of all, the addition of zinc to the composition of the metal immediately reduces the likelihood of corrosion. As an additional protection, polymer layers are applied to the metal.

  • Light sheet weight. The roofing grades of the profiled sheet are very light in weight, so there is no need to create a reinforced truss frame, it is quite possible to get by with something simple.
  • Great leaf length. Thanks to this fact, you can safely purchase a sheet of metal that will fit your slope. The minimum number of joints will ensure good tightness of the roof and, as a rule, long-term operation.

By her own metal roof a good thing, but do not forget about the shortcomings.

  • Roof decking has a smooth surface. Of course, this is not bad in a sense, because the removal of precipitation in winter time year will occur naturally, but all this will be a disadvantage. If you live in snowy regions of the country, then you will have to install snow retainers so that the snow does not avalanche.
  • High thermal conductivity. A thin sheet is not able to retain heat leaving the roofing room, therefore, you will have to spend a large number of energy.
  • Low soundproofing. Noise coming from outside will echo through the attic space. You will even hear the birds landing on the roof, not to mention the rain.

The last two drawbacks can be eliminated by laying a thick insulation, but then the total cost of the entire roofing system will increase significantly.

metal tile

Metal tile can be attributed to the already middle class building materials. It looks good on absolutely any houses. In addition, imitation of natural tiles allows residents to rise in the eyes of neighbors or guests.

This product is still produced from rolled steel, but using a different technology than corrugated board. This sheet of metal has a more pleasant appearance, but otherwise I don’t see a difference. All the same protective components made of polymers and zinc. The only thing is that metal tiles can be made from non-ferrous metals, such as aluminum or copper. However, there are few such enthusiasts.

I would like to note that today there is a lot of this coating in the construction markets. If you do not know how to cover the roof of the house, then choose a metal tile from the following options:

  • Andalusia
  • Shanghai
  • Monterrey
  • Cascade
  • Valencia

All of the above types have good reviews from different classes of developers. But do not blindly rely on advice, study the material yourself and only then decide whether to buy it or not. If you do not know what material to cover the roof of the house, then it is better to seek help from specialists. This product is very similar to corrugated board, so I will not consider its positive and negative sides, if something is not clear, then see the previous paragraph.

Before considering the following coating, I would like to tell you a little about condensing moisture, because this is the main enemy of metal roofs.

Condensation occurs due to excessive humidification of the air in a certain room. Since the rafter system is the skeleton of the entire roofing system, we will protect it first of all. The attic space must be well ventilated, otherwise all elements will rot and fail. The same applies to roofing cake. Here, the materials will not rot, but will lose all their useful qualities.

In order for natural ventilation to cope with its duties, it is necessary to calculate the airflow and ensure unhindered air outlet. The vents should be under the cornice overhangs. Their height, as a rule, is in the range of 5 to 8 centimeters. Having ensured the influx of air masses, you need to take care of the withdrawal of moistened ones. For this, a perforated ridge is installed. It contributes to the removal of steam from inside the room and, in addition, blocks access to the attic space for various pests.

If you are considering this particular material as a covering, then keep in mind that it is better to roof in warm and dry weather. Then the wood will not be able to soak in moisture and will remain dry for a long time. Otherwise, you will start operating the roof immediately with a large amount of moisture, and this can seriously undermine the quality of the truss system.

Many developers do not understand one detail. It seems they have chosen the material, but they still don’t know what is the best way to cover the roof of the house. There is only one answer - what suits you best. Rely on individual preferences and create a custom home of your dreams.

bituminous tiles

It is cheaper to cover the roof of a house with shingles, but you should take care of creating a quality foundation.

As you understand, bituminous tiles are made mainly from a bituminous component. But in its composition there are many impurities that protect the material from external influences. I would like to note the mineral dressing, which does not allow the sun's rays to act on the bituminous parts of the material.

There are quite a few varieties of soft tiles, but they differ not in the composition of the product, but only in its appearance. For example, some manufacturers produce material of 1 meter, while others have a maximum length of only 0.8 meters. Due to the pigments used, manufacturers achieve beautiful patterns on the surface of the shingle, which significantly increases the aesthetic properties of this product.

Advantages of shingles:

  • The shingle has small dimensions and low weight, so the installation process can be carried out by one person.
  • The rough surface repels extraneous noise, therefore, if you plan to residential attic there is no need for additional soundproofing.
  • Due to the low density of the material, heat does not quickly escape through the roof.
  • Bituminous products are not subject to rotting and corrosion, so they will serve their stated period without any problems.
  • The duration of operation is about 30-50 years. Everything will depend on the quality of the material itself and its manufacturer.
  • Large assortment of colors.

Both sides of the coin need to be examined to see the full picture, so let's look at the disadvantages of soft shingles.

  • Contains bitumen. From the previous paragraphs, you already know how bitumen behaves in frost and heat, so you will have to carefully choose the moment for installing such a roof.
  • Roof systems with a slope of 12-18 degrees should be equipped with an additional waterproofing sheet, especially in serious nodes such as valleys or cornice overhangs.

  • Move across the rooftop summer time year is unlikely to succeed, since you will simply damage the canvas.
  • Due to the rough surface, a fairly large amount of precipitation will accumulate on the roof and you will have to take up a shovel to eliminate them.
  • Flammability. This has already been mentioned, so there is no need to repeat it.

As you can see, there is something to think about here. Many developers cover the roof of the house with different materials, but is it effective?

Other coatings

Remained roofs such as seam roofing and tiles. I won't talk too much about them since they are extremely rare.

Seam roofing is a roof made of ordinary straight steel sheets. It is brought to the facility in rolls, and only then it is rolled out and adjusted to size. In addition to steel, any other metal can be used, which will not greatly burden the roofing system with its weight. The whole essence of this coating lies in its installation, or rather the creation of folds. Folds are called joints between strips of metal.

In appearance, such a roof is not very attractive, although the first years it looks solid. The use of cheap metal destroys the entire canvas and over time it becomes corroded. And looking at rusty metal, and even on your roof, is an unpleasant thing, isn't it?

Now let's move on to shingles. If you decide to make such a purchase, but still want to save money, then it is better to cover the roof not with clay, but with cement. In appearance, there will be no differences, except perhaps in color. It is worth noting that for the installation of these roofs, you will have to assemble a serious truss system, otherwise everything will simply collapse.

If we draw a conclusion from all of the above, then it’s impossible to say for sure what is better to roof a roof in a private house. For some residents, asbestos slate will be quite enough, while for others, natural tiles are not enough. However, if you do not strive for frills, then you can consider slate, corrugated board or ondulin. Otherwise, get shingles or metal roofing.

Flat roof coatings

So, I told you about coatings for pitched roofs, and now we turn to flat ones.

Many developers erecting a building with a flat roof immediately run to consult with roofers or turn to a design bureau. Almost all people ask the same question: “what is the best material to cover the roof of a house?” Here is exactly the same case as with pitched ones, since there are fewer materials.

Bituminous roll materials

Roofing material can be called a bright representative of rolled materials. To this day he has suffered major changes composition, this led to an increase in its service life. Previously, the duration of operation was about 5-7 years, and a modern product can lie on the roof for more than 15.

bituminous roll materials are installed using the fusing method. For this, it is used gas cylinder and a special burner. This work is not safe, so if you plan to do it yourself and for the first time, then it is better to invite an experienced partner.

The structure of the material is thin, so you have to lay it in several layers, ideally if their number is 3-4. All layers are laid perpendicular to each other in order to reduce the likelihood of moisture leaking into the seams. The top layer of the roof should be laid with a special roofing material with mineral dressing. It will protect the canvas from the harmful effects of UV rays and mechanical stress.

Liquid, mastic and spray materials

If the roofing surface is not exploited, then bulk, mastic or sprayed products can be used as a coating.

These coatings give the surface 100% waterproofing and adhere well to the surface. When arranging such materials, it is very important to make a high-quality slope, otherwise puddles will form on the roof, creating an additional load on the underlying elements.

Mastic materials are applied using a roller or other hand tools. When laying such a roof, a reinforcing mesh can be laid so that the substance is distributed over the surface more evenly. The result is an effective, but far from attractive roofing surface, and even with a serious drawback: you cannot move along it. However, it is quite suitable for temporary structures.

Sprayable materials include coatings such as liquid rubber. Implement self-laying you are unlikely to succeed in applying this substance to the roof surface, since you will need expensive equipment and the ability to distribute the amount of rubber over the plane.

membranes

Membranes are still considered modern products, although they were invented a long time ago. These products are made on the basis of polymers, which perfectly resist moisture and do not let it through their thickness. It is worth noting that it is not effective to use such a coating on small areas, so the membrane has found great popularity in industrial construction.

Membrane roofing is divided into three types:

  • TPO. The basis includes thermoplastic olefins with impurities of antioxidants, plasticizers and synthetic rubber. The output is a strong and durable material with increased fire resistance.

  • EPDM. Expensive coating with a reinforced body. This material justifies its cost due to long-term operation.
  • PVC. AT modern world Almost everything is made from polyvinyl chloride. This connection makes roofing material cheaper than similar analogues, which greatly attracts developers.

If you are trying to understand the best way to cover a flat roof at home, and to make it cheaper than others, then pay attention to roofing material or mastic. Well, if aesthetics are important to you, then naturally choose polymers.

Safety precautions when dismantling slate from the roof

The disassembly of the roof should be carried out, observing certain safety measures:


Dismantling the old slate from the roof

The easiest way is to remove the old slate coating with your own hands, if the material is no longer suitable for further use. Traditionally, such a roof was mounted using ordinary or ruffed nails, so for the work you only need a nail puller, a hammer, a knife for cutting waterproofing, a ladder and a long ladder.

First of all, you need to get to the roof ridge and, using a nail puller, remove the fasteners that hold the ridge element from wooden planks or bars, roofing material or sheet metal. This will release upper part top row of slate. Then the sheets of roofing material are removed, starting with the one that was last when laying - it is easy to determine by overlapping on an adjacent element.

Since the integrity of the old slate is not required to be preserved, in order to release the sheet, it is enough to hit the nail heads hard with a hammer, sinking them into the wood. Holes are formed at the attachment points and the sheet, in whole or in parts, can be thrown down. Further, the fasteners remaining in the crate are pulled out with the help of a nail puller.

Dismantling the slate without damaging the sheets

If the old sheet material is suitable for reuse, the roof should be disassembled with extreme care. In this case, work also begins with the removal of the ridge element. Then the slate sheets are removed in the opposite order of laying roofing. The principle is simple: carefully, without damaging the sheet, fasteners are removed, and the removed roofing element is carefully lowered to the ground.

Without any problems, you can remove the fasteners if the roof is mounted on self-tapping screws. They are unscrewed with a wrench (if the fastener has a hex head) or a screwdriver with a suitable nozzle (for a straight or cross slot). But this option is only possible when disassembling a fairly new roof.

Smooth nails are pulled out with the help of a nail puller, under the heel of which it is necessary to place a plank - this will prevent the sheet from splitting under a point load. If the nail passes through the crate and its tip is bent, then it can be removed in two ways:

  • remove layers of vapor barrier, insulation and waterproofing from the inside of the truss system, straighten the free part of the nail and knock it out from the bottom up, then pull it out with a nail puller from the outside;
  • bite off the nail head with a suitable tool (lever pincers, mini-bolt cutter, etc.) or cut it off with a grinder.

Ruffed roofing nails (there are special corner notches on their body) are inherently non-removable fasteners - with the help of a nail puller they cannot be pulled out without breaking the nail itself or without damaging the slate material and the crate. Therefore, their hats are bitten off or cut off.

How not to damage the slate when removing to the ground

It is most convenient and fastest to carry out dismantling with three people:

  • one person stands on the stairs or on the crate of that part of the roof where the coating has already been removed, and dismantles the fasteners;
  • the second person sits on a skate or is nearby, holding the sheet, helping to tie it with a rope and remove it, gently lower it to the ground;
  • the third assistant is on the ground, he unties the rope from the removed sheet and takes it aside, carefully stores it.

When working alone, it is more convenient to start dismantling the roofing with your own hands from the extreme element of the bottom row. Having removed the fasteners from it, the sheet must be moved and pulled, releasing. Remember to immediately cut off the waterproofing material so that you can easily move along the crate, using it as a ladder.

It is not advisable to use a rope to lower sheets - it is difficult to handle a slate sheet alone, the weight of which exceeds 20 kg. In addition, you will have to constantly go down the stairs to untie the rope.

In this case, it is necessary to take two or three long boards and set them at an angle of about 40-60 degrees, resting one end on the ground and placing the other on the ledge. On these parallel guides, it is easy to lower the sheets to the ground, “accumulating” three elements one after the other - the slate sheets will rest against each other's end. As a result, you will have to go down to the ground less often, which will save strength and reduce work time.

So that the slate does not split, it is necessary to provide sheets " soft landing» - put bags, rags or other soft material at the base of the descent!

When building a roof, different materials are used as a roof: these are slate, and tiles, and many others. But the roof covering with iron remains the most demanded. If you have the material, you can do the roofing yourself.

Preparatory stage

Covering the roof with iron with your own hands begins with the preparation of sheet steel. When transporting, you need to be extremely careful so that there are no scratches and chips.

  1. A layer of lubricant is removed from the metal sheet.
  2. Drying oil is applied on top, which is enriched with dyes.
  3. After the drying oil dries, you need to identify unpainted areas and paint over.
  4. Along the edge of the steel sheet, you need to bend a fold - a technological fastening element, which is also called a lock.

The fold is of two types: standing and recumbent. Sheets can be connected both longitudinally and transversely. And only in a metal tile the sheets are overlapped.

Making a fold

To make a fold yourself, you will need tools:

  • calipers;
  • comb bender;
  • mallet made of wood;
  • metal scissors;
  • workbench with a steel corner, a metal hammer with a flat side;
  • ruler.

With this set of tools, you can make a lying fold.

  1. Put a sheet of iron on the edge of the workbench.
  2. Mark the edge line, holding the sheet so that the line runs smoothly and does not move.
  3. Using a mallet, bend the corners of the edge exactly along the line, you should get a beacon bend. It will allow further work to be done more accurately.
  4. After the bend is made along the entire length of the edge, you need to turn the iron sheet over and bend the edge to the end.
  5. Process another sheet in the same way, then it will be possible to connect them together.
  6. The connection points must be fixed with a hammer.
  7. The longitudinal edge gives the necessary scar.

The standing seam is made using the same technology on the roof. To make a lock for ordinary sheets, you need to use a comb bender.

Roof coating technology

You can also prepare iron sheets for roofing work in the workshop, but you need to mount them on the roof itself. Before you start working at height, you need to make prefabricated elements from steel sheets directly on the site. This will make it easier to install later.

What to produce correct coverage iron roofs must follow the instructions:

  1. With the help of ready-made recumbent folds, sheets of iron are interconnected on one side. The prefabricated element must consist of at least two sheets on the short side, and as a maximum - for the entire height of the roof slope.
  2. Fasten the fold between the sheets, observing one direction.
  3. Check if the sheets are correctly positioned relative to the vertical.
  4. Strengthen the connections with a steel strip and a hammer.
  5. The bend through the ridge must be done so that the edge on one slope is bent by 6 cm, and on the second by 3 cm.
  6. You need to fix the iron by first fastening the bend at the ridge, and then fixing the entire strip.
  7. The sheets are fixed with clamps, which are attached to the roof lathing, to the beams.
  8. If the sheets are profiled, then they must be fixed to the roof with special nails with rubber seals.

A roof made of materials with a polymer coating will not need to be covered with anything on top for all the years of operation. But ordinary steel will need to be primed and painted. This must be done immediately after completion. roofing works. Steel sheets need to be painted twice. How the iron roofing looks like can be seen in the photo.

A high-quality roof is an important element of any building, whether it is a high-rise building or a small one. Vacation home. Most of the houses built several decades ago and having slate roof, no longer meet modern requirements - slate is no longer the most practical material for roofing, and, in addition, it tends to wear out quickly enough.

In this case, it is advisable to cover the slate roof with corrugated board. This material meets all modern requirements for thermal and waterproofing, has high strength, and, at the same time, is durable, and also has a presentable appearance. appearance and ease of installation.

Advantages of corrugated board

Roof covering is not the easiest operation and some builders prefer not to change technologies for a long time. However, covering the roof with sheets of corrugated board has a number of advantages over slate, due to which its use will be a more profitable option when replacing roofing.

Decking, also known as trapezoidal sheet, has the following advantages over traditional roofing:

  • small thickness and, as a result, less weight;
  • high strength and durability;
  • high-quality protection against precipitation;
  • ease of installation.

Decking is made of metal by cold rolling and has a thickness of not more than 1 mm, respectively, its weight will be less than that of a slate of equal sheet area. In addition, due to the material and wave shape, it has high strength, longer service life and copes well even with heavy rainfall.

Also, the service life of the sheets is affected by the presence of a special coating - galvanized or colored polymer. Due to the possibility of painting in almost any color, this material has a much greater aesthetic appeal compared to slate, and at the same time, it is much easier to mount it, since the metal is well drilled.

Varieties of corrugated sheets

In order to qualitatively cover the roof with a profiled sheet, it is necessary to choose its variety correctly. There are three types of this material:

  • C - the thinnest;
  • HC - medium thickness;
  • H is the thickest.

Profiled sheet type "C" has a small thickness and a low wave profile, not exceeding 44 mm. Due to its characteristics, it is used as a material for decorative sheathing of fences and buildings, as well as for laying as a roof covering on gazebos and other small structures.

The profiled sheet of the "NS" type has average characteristics compared to other types of this material: its sheet thickness is up to 0.8 mm, and the wave size is from 35 to 33 mm, which allows it to be used to cover the roof of residential buildings small size, which are most often private houses and cottages.

Profiled sheet type "H" is distinguished by the largest possible sheet thickness and wave height: they range from 1 to 2 mm and from 57 to 114 mm, respectively. Its main area of ​​application is covering the roof of large buildings, use as a roof covering for industrial facilities, as well as formwork in the construction of foundations.

Sheet stacking method

After the choice of the type of profiled sheet and its purchase is made, they cover the roof. The main method of carrying out this procedure involves laying sheets with an overlap.

In this case, it is important to take into account the steepness of the roof slope, since the amount of overlap depends on it - the smaller it is, the greater the overlap should be, and the more material may be needed as a result.

With a standard slope in a private house, the roof should be covered with an overlap of 15-20 cm, and when installing a roof in a country house, which most often has a steeper slope, the overlap can be 10-15 cm.

Work order

In order to qualitatively cover the roof with corrugated board, it is recommended to carry out the procedure in two stages:

  • arrangement of the crate;
  • laying sheets.

The choice of the method of framing depends on the type of attic: if it is assumed that it will be unheated and, as a result, not residential, then laying roofing material is sufficient for framing. It is important to remember that when installing sheets, the roofing material must be securely fastened to the rafters in order to prevent it from rolling down from the roof slopes. To do this, it must be securely fixed - this can be done, for example, with a stapler.

If the attic is planned to be made into a living space, then the roof should be insulated by arranging a crate with thermal and waterproofing. For this, modern special-purpose materials are used - insulation and membrane films, which allow creating favorable conditions in the attic and providing reliable protection against the formation of condensate. In extreme cases, you can use the same roofing material, but its effectiveness is lower at times.

Sheet stacking

Covering the roof with a profiled sheet is quite easy, and you can guess how this is done without extra instructions, but some nuances should be taken into account. Firstly, to fix the sheets, it is better to use special roofing screws with a rubber washer that provide waterproofing for the coating.

Secondly, it is necessary to ensure that the edge of the sheet is in the hollow, and not on the crest of the wave. This will significantly increase the strength of the structure, as well as facilitate its installation.

It is also important to note that if the wall is high enough, the most convenient way transporting sheets to the roof will use the log. Also, if the roof is gable, you can use a long rope, which is pulled through both slopes and with its help the sheets are pulled up.

You have decided to replace your heavy slate roof with a lighter one. modern material? Don't rush to hire expensive professional roofers. In this article, RMNT will tell you how to do all the roofing work on your own.

Until recently, asbestos-cement slate sheets, invented back in 1901, were considered the main roofing material. Such an “eternal” roof met all the necessary qualities that were relevant at that time, but it also had one significant drawback - an impressive weight. Today, with the advent of new roofing materials on the market, slate is rapidly losing ground. The population en masse covers the roofs with ondulin, corrugated board or. At the same time, the hired construction teams, in order to increase the estimated cost of the work, as well as to make life easier for themselves, often convince the customer to carry out a complete dismantling and make a roof from scratch. Others believe that it is enough to simply remove the old roofing material and you can safely lay a more modern one. The truth, as always, lies somewhere in the middle. Let's try to explain how to actually do it.

Dismantling works

In order to build something new, we must first remove all the old that interferes with us. That is, to carry out dismantling work. And, of course, you need to start dismantling with ... a weather forecast. Before you start roofing work, you should find out if weather forecasters promise us long and prolonged rains. After all, we are already blocking the living quarters, with all the internal work, so the ingress of precipitation inside is categorically undesirable.

Important! Even if the weatherman gave the go-ahead, still stock up on film, tarpaulin or other waterproofing.

For dismantling, we need a nail puller, a block of wood, ropes and a pair of hooks as thick as a slate nail, as well as two guide beams that will serve to safely raise and lower roofing materials.

Dismantling should begin in the reverse order to installation, that is, first we remove the skate, then the top row of slate, and so on until the bare crate. We pull out the nails with the help of a nail puller, placing a wooden block in the last stop. Asbestos-cement sheets should be lowered along wooden guides, hooking them previously to the holes made with nails with hooks. Lowering the slate just by a rope is not safe.

Do not try to dismantle the slate from the entire roof at once, if the team is small and you do not have time to cover the roof in one day, replace it in stages, first repairing one slope, then the next.

Following the slate, we also dismantle the old crate, leaving only the bare rafter system on the plane.

Rafter system repair

Since the requirements for the plane of slate and corrugated board are different (for the installation of corrugated board, a perfectly flat surface is required), we will build this plane.

First you need to pay attention to the condition of the extreme rafters and the presence of a plane as a whole. To do this, in all four corners of the slope we are repairing on the rafters, we twist the screws so that all 4 hats are not screwed 3 cm to the beam. From corner to corner diagonally, as well as along the rafters, we stretch the lacing. Checking in this way whether the plane is flat and whether there is a bump on the wooden structure. The threads stretched diagonally should barely touch each other at the intersection. If the plane is missing, we build it by unscrewing (but not twisting) the necessary screws.

Now, using the extreme rafters as beacons, we pull the laces between them in increments of 1.5-2 m and audit the rest of the truss system. If necessary, we level the rafters with an edged board, and in case of severe damage to the tree, we will completely replace them. In any case, 2 people who simply have the skills to handle construction tools will cope with such work without much labor, while the manufacture of a new truss system requires the forces of an entire construction team with the participation of truly roofing professionals.

Lathing manufacturing

The next step is the laying of the waterproofing membrane. It is laid horizontally on top of the rafters, starting from the bottom and rising to the ridge. Waterproofing must overlap so that water flows over it. We nail the film to the rafters with a stapler.

Important! You can not lay the waterproofing "stretched", it should sag slightly, thereby increasing the size of the ventilated space.

In parallel with the hydrobarrier, we mount the crate. If this is not done, then there will be problems with how to get to the plane of the truss system without damaging the waterproofing membrane.

The installation of the lathing begins with the installation of a support beam (50x40 mm), which is attached over the waterproofing film along the entire length of the rafters. For installation, we use a self-tapping screw 4.2x75. The installation step is 35-40 cm. It is not necessary to use a beam long for the entire rafter, blanks of 1-1.5 m are quite suitable.

For the transverse crate, an edged “shalyovka” is suitable - a board measuring 25x150 mm. We start installation from the eaves itself and ending with the ridge. The first and last boards should go along the very edges of the rafters, the rest should be located in increments of 450 mm, that is, a 30 cm template must be installed between the boards (the crate is designed for C21 grade corrugated board, for other types of iron the crate step will be different).

When the crate is finished, we move on to the second slope. We also carry out all the above operations. The difference lies only in the installation of the last ridge board. It should cover the corresponding board of the opposite slope; for this, the latter is trimmed with an electric planer. Both boards are protected with one piece of waterproofing membrane, securing it with a stapler.

Lastly, we mount the wind board. It is attached to the end of the crate and should protrude above it to the height of the corrugated board wave, it can be a couple of millimeters lower.

Installation of corrugated board

When the work with the tree is completed, you can proceed directly to the installation of corrugated board. It would be nice to get it in size, equal to the length stingray. This is the distance from the ridge to the end of the rafter, plus another 5-8 cm.

The sheets are carefully removed from the pack and fed to the roof along inclined guide bars; for convenience, a couple of holes for hooks can be made in the outer wave in that part of the sheet that will be covered by the ridge.

Important! Sheets of corrugated board from the pack must be removed, and not pulled off. The polymer coating is very easy to scratch.

The first sheet is exposed very carefully. It will depend on him how the rest of the iron will lie. To do this, we fasten flags to the extreme rafters, small slats 20-30 cm in length, which are installed in the same plane with the rafter system and protrude 10-15 cm beyond its limits. At a distance of 5-8 centimeters from the eaves, a self-tapping screw is twisted into such a rail strictly perpendicularly so that its head is higher than the height of the corrugated board wave. Further, between the two extreme flags along the height of the wave of the metal sheet, we stretch the lacing. If it sags, the flags can be duplicated. Leveling on a thread, it is much easier to expose iron.

Important! Any trimming of corrugated board should be carried out from the side of the ridge, from the side of the cornice there should be only a factory cut.

The corrugated board is mounted to the crate using screws with press washers at the rate of 6-8 pieces / m 3. It is useful to calculate and outline the attachment points on the ground.

Important! We twist the screws without fanaticism, the press washer should press the iron to the crate, but at the same time not deform much.

We mount wind corners and a skate. It is much easier to do this work right away than to climb slippery iron later, with the risk of crushing or scratching it. To fix the ridge, long drills with a press washer are used, which can pierce the thickness of the corrugated board and gain a foothold in the tree. Installation is carried out through an external wave.

Important! All high-altitude work is carried out only with the use of insurance and with the good health of the master. Violation of these simple rules can lead to tragic consequences.

A few decades ago, slate was considered the most popular and practical for roofing, and many private houses and industrial facilities still have a similar roof.

Today, many prefer to replace outdated material with a more modern and convenient one.

In this article we will talk about the features of replacing the roof.

Replacing slate with profiled flooring

Invented at the beginning of the last century asbestos cement sheet for that time was considered the most revolutionary and impeccable material. Roofers were sure that by making a roof, they provide reliable protection for the house for centuries.

With all the advantages, slate sheets had one, but a very significant drawback.

The weight of such a roof was very significant and required the installation of beams and other load-bearing elements with special care. Massive logs and beams or metal bases were used.

Slate roof

Today the positions of yesterday's sales leader are moving back. Innovative, strong, durable and lightweight roofing materials have appeared.

We can say that andulin is more actively used by builders at the present time.

You need to be well versed in the technology of roof installation in order to independently replace the outdated coating. If you are not confident in your abilities, it is better to involve proven, well-trained professionals who can give useful advice on the device and alteration of the roof.

Advantages of using corrugated board

  • The most significant advantage for the owner is the light weight of the sheets, and therefore the minimum number of workers to carry out work to replace old material with corrugated board.
  • Another significant plus is the high bending strength of the sheet, thanks to stiffeners, which makes it possible to carry out installation with minimal effort to preserve the material during construction.
  • The service life, subject to the installation technology of the roof structure, is practically unlimited.
  • Affordable price allows people with average incomes to use it when repairing or building a roof.
  • However, it should be noted that corrugated board requires good, which is especially evident when precipitation occurs in the form of rain or hail.

What to do with old slate

Reference: In order to make the structure as light as possible and to examine the system of rafters and beams, it is necessary to remove the obsolete roofing material.

Some owners believe that it is possible to cover the old slate with new material and thus make the roof more reliable, while it is assumed that they can save on soundproofing.

Important! This approach is fundamentally wrong. You load the structure with an unforeseen weight, and in winter, during heavy snowfalls, the roof may not withstand the additional load. It is necessary to remove the old asbestos-cement material and replace it with a new, more durable and comfortable one.

Dismantling of old material

The first step to start removing the outdated and spent slate is a close acquaintance with the nearest weather forecast. We need to make sure that in the coming days it will not start to rain.

Important! Even after making sure that weather forecasters guarantee clear, dry weather in the coming weeks, stock up on film and, just in case, close the attic with waterproof protection.

The main tools for roof replacement are

  • nail puller
  • several strong hooks
  • ropes
  • wooden bars.

This simple kit is needed for safe work when removing and lowering old slate roofing sheets. Work order reverse installation, that is, it is necessary to start by dismantling the ridge and the top row of slate, gradually going down until the old coating is completely removed.

The crate should remain completely bare so that you can make sure that it is intact and, if necessary, replace the failed structural segments.

Pulling out nails is carried out using a conventional nail puller, under which, for convenience, a small wooden block or a piece of board is placed.

To lower the slate, thread special hooks into the holes left by the nails and place them for better glide. wooden bars. It must be remembered that shooting with ropes alone is much more dangerous.

Removing the entire array of the old roof is not rational, because if you cannot immediately lay new material, then no matter what the weather forecast guarantees, there is always a chance for unexpected precipitation.

Help: Break down the upcoming work into stages.

Remove the slate from one slope and lay a new corrugated board. This will save you from surprises related to the weather.

Rafter repair steps

For the installation of profile sheets, a flawless, even surface is required, so special attention should be paid to the quality of the old rafters.

It should be checked to what extent the design has retained its operational qualities: it meets the requirements for reliability and safety. Make sure that all beams are not cracked and have not been attacked by pests (bark beetles, longhorn beetles and lumberjacks, wood borers and house grinders).

If necessary, wooden structures must be replaced and treated with means to prevent the penetration of insects - pests, mold and fungi.

Flat plane check:

  • screws are twisted at the corners of the disassembled ramp so that the hats rise several centimeters above the rafters;
  • pull the string. You can use the level to check how even the surface of the future roof is, and whether there are bumps or notches in the plane of the slope;
  • if the threads stretched diagonally barely touch each other, then the plane is perfectly flat, otherwise you need to unscrew the screws and bring the plane to the desired state;
  • the final leveling is carried out using an edged board, fastened to the beam with bolts.

After that, you can use the extreme rafters as beacons and revise the entire structure.

To even out defects, you can use an edged board, and elements that have completely become unusable must be replaced, not forgetting to pre-treat them with a special composition.

Repairs can be quickly handled by a couple of people with minimal experience in construction work.

Conclusion: Independent revision and repair of the truss system will save significant funds for materials and payment, which are expected with the complete replacement of this important roof assembly.

Lathing installation

Do I need waterproofing when replacing a roof from slate to corrugated board?

The answer is obvious - it is necessary. See for more details.

We put . The membrane is attached horizontally to the rafters. You need to start from the bottom and work with an overlap to prevent leakage. The material is fastened with a construction stapler.

Reference: Do not stretch the membrane too much, let it sag a little, this will ensure good ventilation of the under-roof space.

In parallel, installation is underway, if this is not done, it will be impossible to get on the roof without damaging the waterproofing.

  • The first step is to install a beam to support the crate.
  • The second step will be the fastening of the transverse boards; for this purpose, the edged “shalevka” is well suited.
  • Work is being carried out from the eaves to the ridge. The edge boards should go exactly along the edge of the rafters. Other boards are fastened in increments of forty-five centimeters.
  • The opposite slope is mounted in the same way, only the ridge board should overlap the opposite board, after which the ridge is covered along the entire length with waterproofing, tightly attached with a stapler.
  • The final step in the installation of the crate will be the attachment of wind boards, they are attached to the end and should protrude slightly above the wave of the attached corrugated board.

Installation of the crate under the corrugated board

The stages of work are no different from installing structures for other types of roofing materials.

The only difference will be the choice of brand and wave profile sheets. The step size of the boards of the crate depends on the brand of materials used.

A set of tools for laying profiled sheets

For quality work, you must have at hand:

  1. Screwdriver.
  2. Hand riveting set for processing joints. Only steel rivets may be used.
  3. For cutting metal, scissors or a jigsaw with special files are suitable.
  4. In addition, you will need a standard builder's set - a ruler, a meter, a level, twine, a hammer, and with special wide hats and a rubber seal.
  5. To ensure good waterproofing, you need a special one, and in case of damage to the top layer of the protective coating, an aerosol with a special paint.

Installation of corrugated board

Sheets rise along the bars or boards, you can make several holes for hooks in the outer wave. You just have to make sure they overlap.

The crown of any structure is the roof, and the safety of the entire building as a whole depends on how reliably it is protected from external factors.

Today, an increasing number of people who have started repairs at their dacha are trying to cover the roof on their own, thereby saving their money.

Recently, corrugated board successfully competes with expensive materials that have traditionally been used to protect the roof. Its advantage is that, in addition to quality, beauty and reliability, it allows you to cover the roof without the help of professionals. If you decide to do it yourself, read this article carefully.

Before starting work, you need to figure out what kind of material we are talking about. Decking is a steel profiled galvanized sheet with or without a polymer coating. Its main distinguishing feature- the presence of a profile that gives this material transverse rigidity. Overlapping the roof with corrugated board makes it possible to facilitate the structure as a whole, since it has a low weight. Thanks to all the above features, this option is recognized as the most economical.

Overlapping work includes several stages:

  • choice of corrugated board;
  • taking measurements;
  • transportation;
  • selection of necessary tools;
  • roof preparation;
  • installation of corrugated board.

How to choose a roofing corrugated board for roof covering?

The structure of the corrugated sheet. The height of the sheet for the roof must be greater than 21 mm.

  1. Profile sheet marking. There are many different markings, but for roofing it is recommended to use corrugated board marked H, at least 20 mm high. It is important to remember that the numbers following the letter of the marking indicate the height of the wave and the useful width. The choice of profile depends on the planned roof structure. The rule applies here - the more, the lower the grade of corrugated board should be. In addition, it is worth finding out which standard was used in the manufacture of profile flooring: TU or GOST. Compliance with the latter indicates a higher quality of the material. Ask for a certificate.
  2. Profile sheet appearance. The surface of the profile must be smooth, the presence of cracks or roughness indicates a low quality product. If the corrugated board is made in color, peeling is not allowed on the paint. Check the profile sheet for strength, if it is easy to bend and break, such a purchase should be discarded.
  3. A high-quality sheet after bending easily returns to its original form.
  4. Price. It depends on three indicators: the thickness of the sheet, the type of polymer coating and the pricing policy of sellers. Sometimes it makes sense to compare prices for the same type of corrugated board from different manufacturers and choose the one that suits you best.
  5. Profile cover. To give the material additional properties, such as corrosion resistance, it is coated with zinc. The more aggressive Environment and the longer the period of use, the thicker the coating layer should be. To add aesthetic appeal to the material, polymer coatings of various colors are used. Here it is worth focusing on your own taste and the exterior of the house.

How to take measurements to cover the roof with corrugated board?

  1. Before you start covering the roof with a profiled sheet, you need to carefully measure and fit its components.
  2. Before installing the roof truss, it is necessary to measure the roof slopes again, since the project may undergo changes during the implementation process.
  3. Before that, you need to make sure that the slopes are rectangular, for this they measure the length of the diagonals of the slopes, the allowable difference is 2 cm.
  4. Be sure to check the plane of the slopes using a level with a cord. Permissible deviations - 5 mm by 5 m. If the indicator is greater, it will not be possible to join the sheets.

Transportation of corrugated board

Despite their strength, profile sheets can be deformed if they are not loaded and transported correctly. Therefore, when going for corrugated board, consider the following points:

  1. The material must be loaded on a solid, solid base, such as wooden logs, which must be longer than the sheets.
  2. To avoid friction of profiled sheets during transportation, they need to be strengthened with slings.
  3. Vehicle speed must not exceed 80 km/h.
  4. It is also worth unloading with caution, it is better to involve two people for this purpose, since it is forbidden to drag or bend the corrugated board.
  5. The process of lifting sheets for mounting is also fraught with certain difficulties, since lifting only needs to be carried out one sheet at a time stretched from the ground. wooden lags. To do this, you need to involve at least 3 people. In windy weather, the material must not be lifted, because it can be easily damaged.

To cover the roof with corrugated board, you will need the following tools:

Tools for mounting corrugated board: 1 - screwdriver or drill; 2 - hammer; 3 - rubber hammer (mallet); 4 - brush with soft bristles; 5 - tape measure; 6 - long rail; 7 - marker (carpenter's pencil); 8 - level; 9 - a tool for cutting metal tiles (metal shears); 10 - pliers.

  • the choice of scissors for cutting depends on the thickness of the selected material: for a profiled sheet of steel with a thickness of 0.6 mm, cut-out shears are taken, for steel of the same thickness - lever shears, for steel up to 1.2 mm, cut-out electric cutters are suitable;
  • drill;
  • gun for distributing sealant;
  • rivet pliers;
  • knife for cutting insulation;
  • staples and a gun to them for fixing hydro- and vapor barrier layers;
  • template for marking the step of the crate;
  • wire cutters;
  • screwdriver;
  • marker;
  • roulette;
  • long rail;
  • a hammer;
  • cord.

Roof preparation

We are talking about the installation of crates, which is an integral element roof structure which helps the roof withstand heavy loads and properly distribute weight. In addition, it performs the following tasks:

  1. Allows you to perform the installation as quickly as possible, thanks to the fastening of the panels to the rails with brackets.
  2. Prevents the appearance of fungus and mold even without additional.

Most often, the crate for private houses is made of wood, since the angle of inclination is large and this reduces the load on the roof.

Roof covering with corrugated board

After the crate has been made, corrugated board is installed on it. Its use is recommended when the length of the slopes is not more than 12 m.

It is important to remember that the angle of inclination of the roof is decisive when choosing the size of the horizontal overlap:

  • if the angle of inclination does not exceed 15 °, then the overlap should be more than 20 cm;
  • if the angle of inclination varies from 15 ° to 30 °, an overlap of 15-20 cm is needed;
  • if the angle of inclination is more than 30 °, it is enough to overlap by 10-15 cm.

Scheme of a corrugated roofing pie for a roof, under which there are residential and non-residential premises.

  1. With a screwdriver with self-tapping screws for roofing in a wave deflection, profiled sheets are attached to the crate. In this case, galvanized self-tapping screws 4.8 × 0.38 with rubber seals are used. Approximate consumption of screws - 6 units. /1m².
  2. At the bottom and top of the slope, the screws must be screwed into the lower wave, and along the middle of the sheet - into each board of the crate.
  3. To fasten the sheets, self-tapping screws or rivets are mounted in the upper bend of the profile with a step distance of 0.5 m.
  4. To install the last sheet on the end side of the roof, a large overlap or cutting along the slab is used to obtain the required size.
  5. The overlap of the end plank is at least 5 cm. The end plank is attached to the sheet every 30 cm so that it overlaps its first wave.
  6. Prior to the assembly of the roofing sheets, self-tapping screws strengthen the cornice strip with an overlap of 10 cm. The approximate screwing step is 30 cm.
  7. For internal joints, corrugated board with a smooth surface is used. The roof under the joint must be covered with a durable deck. The gap that the corrugated sheet forms with internal joint must be sealed with a sealant. The joint on the ridge is fixed with nails, in the deflections - with screws, observing a step of 30 cm.
  8. Planks are laid with an overlap of 10 cm, they are fixed every 30 cm with self-tapping screws or screws.

The roof covering with corrugated board is completed.
