Among the many modern roofing materials, one of the leading positions in popularity is held by euroslate - a flexible and comfortable coating that has replaced traditional asbestos-cement sheets.

Euroslate modern roofing material.

Euroslate - optimal solution for any roof.

Today euroslate is successfully used both in residential and industrial construction.

Euroslate it is an environmentally friendly and very aesthetic material that has replaced the traditional slate. If we talk about Euroslate, then from ordinary slate, Euroslate differs primarily in that it does not contain asbestos, which was part of its predecessor, and the cost has its advantages over slate.

Euroslate is an elastic and durable corrugated coating, the basis of which is cellulose cardboard sheets impregnated with bitumen or rubber polymer.

Euroslate does not rot, acid-resistant, resistant even to significant temperature changes, which is especially important for our climatic zone.

To understand what it is and how euroslate differs from its predecessor from asbestos cement, it is enough to study its composition, which includes:

  • fiberglass;
  • cellulose;
  • mineral filler;
  • refined bitumen and other resins.

All these components are exposed to high temperatures and impregnated under pressure with special resins with the addition of coloring pigments.

Each component performs a specific function:

  • cellulose and glass fibers make the material strong, rigid and resistant to external loads;
  • resins give the material moisture-proof properties;
  • coloring pigments and mineral additives are necessary to give an aesthetic appearance, as well as increase resistance to negative effects. external factors(molds, chemicals, UV rays).

The whole manufacturing process roofing sheets produced on special equipment using the latest technology.

Due to the fact that euroslate is made from natural ingredients, its main advantage over most roofing materials is environmental friendliness.
Euroslate is ideal for the construction of lightweight hangar-type structures. Such material as euroslate will decorate any house, regardless of its architectural features.

Euroslate does not crack or break, does not rot or rust, and serves for decades in any climatic conditions. Considering the foregoing, as well as regarding low price on euroslate, we can say with confidence that at present this material bypasses its main competitors in most parameters. Practicality and durability are the main advantages of euroslate.
The high moisture resistance of euroslate allows you to significantly save on waterproofing materials, and the simplicity of its installation allows, if desired, to perform this process independently.

Roofing with euroslate is much easier than with other similar materials. Lay it on a wooden crate treated with an antiseptic. The sheets are overlapped, the size of which depends on the angle of the roof.

  • So, with a slope of up to 10 °, the slate is laid on a continuous crate, overlapping one sheet with another by 30 cm in the vertical direction and by 2 waves in the horizontal direction.
  • If the slope is 15 °, then the elements of the crate are installed at a distance of 45 cm, and the overlap of the sheets of roofing material is 20 cm vertically and 1 wave horizontally.
  • If the roof angle exceeds 15 °, then the lathing step can be increased to 60 cm. In this case, the vertical overlap of the sheets will be 17 cm, and the horizontal one - 1 wave.
  • The seams between the sheets are made "in a row". To do this, each even row begins to be installed from half the sheet.
  • If necessary, the material is cut with a conventional hacksaw. pre-lubricated with machine oil. Such processing of the tool will not allow it to get stuck in the sheet and significantly speed up the process.
  • During installation, the sheets are attached special nails with propylene or rubber washers. Nail the material through the wave. The resulting holes are sealed with butyl rubber mastic.
  • About the popularity of Euroslate, made according to modern technologies, evidenced by numerous customer reviews.
  • For many, the environmental safety of the material is of paramount importance. For others, its practicality and aesthetics. At the same time, all consumers agree that the service life is much longer than the asbestos-cement counterpart.
  • In addition, buyers appreciate the combination of an affordable price with high quality product and ease of installation.

Currently, euroslate is offered by various manufacturers, whose products may differ both in technical specifications, as well as for the price. There are several of the most popular brands.

- Onduline. The most famous version of euroslate.

  • The composition of the Ondulin Tiles includes simple and reliable materials: bitumen, resins and cellulose. The roof withstands harsh climatic conditions and permanently waterproof.
  • The surface of the Onduline Tiles is now covered with 2 coats of paint. For comparison: a metal tile has only 1 layer. The roof remains bright and beautiful for a long time.
  • Tiling thickness - 3 mm. Ondulin Tile sheet withstands loads up to 960 kg/sq. m is approximately 3 cubic meters of dense snow.
  • heterogeneous pattern and matte coating Tiles Ondulin creates the effect of a real tile. View natural tiles with a weight of 3 kg / sq. m.
  • Has a snow-retaining surface. In winter, you can not be afraid to walk near the roof. Environmentally friendly for people and environment. Virtually silent during rain and hail.

- Ondalux (Ondura). Produced in Russia by Ondulin at one of its factories.

  • Ondalux You can meet on the roofs throughout Russia.
  • Installation of Ondalux (Ondura) does not require any special training. All you need is a hacksaw, hammer, pencil, roofing nails(based on 15 nails per sheet) and fastening instructions.
  • The weight of one sheet of Ondalux is only 5 kg - you do not need reinforced floors for home or outside help in installation. You can even leave the old roof by putting Ondalux on top of it. By the way, the weight of 60 sheets of Ondalux is only 300 kg., You can use personal transport and not bother with delivery.

- GUTTA (Gutta). One of the most economical solutions for roofing and wall cladding, has been used for several decades.

Advantages:

  • low price
  • do not require maintenance
  • high speed styling
  • long service life
  • natural colors
  • light weight

Slate long time was a non-alternative budget roofing material. However, its shortcomings (fragility, hygroscopicity, the danger of asbestos for humans) did not suit everyone.

Today, an alternative has been developed for it, which is just as natural and inexpensive - bituminous corrugated sheet or, as it is often called, Ondulin (the most well-known manufacturer). Other names are euroslate and aqualine. The roofing material is made on the basis of thin cellulose fibers, impregnated with bitumen and supplemented with polymer additives.

Main advantages of corrugated bitumen sheet

  • Ease of installation. Negligible weight (about 3 kilograms per "square") and ease of cutting with a conventional hacksaw simplifies roofing and facilitates transportation.
  • Versatility. Ondulin is suitable for almost any roof, including complex profiles. Besides, given material can be used for roof repairs.
  • Reliability. Bituminous sheets withstand loads up to 960 kg/m 2 . They also have excellent water resistance. chemical substances and biological agents.

Euroslate (ondulin) - bituminous corrugated sheet

In our country, for many years, such roofing material as slate has been very popular. This material is able to effectively protect the roof from environmental influences and at the same time has a low cost. But, at present, this popular roofing material is increasingly giving way to euroslate, which is also called ondulin (onduline).

Ondulin, at a relatively low cost, has much better operational characteristics and a greater variety of colors and shades than conventional slate. If we compare euroslate with ordinary slate, then the difference in composition and production technology between these two materials will be very different.

Production and composition of euroslate

Euroslate contains modified bitumen, plasticizers, dyes, vegetable or synthetic fibers. The purpose of these materials is quite obvious. Bitumen gives ondulin water repellency, vegetable or synthetic fibers strengthen the euroslate, as a result of which it acquires the ability to resist mechanical stress. With the help of dyes, absolutely any color can be given to this roofing material, thanks to which euroslate will decorate the roof of any house, giving it a presentable and individual appearance.

In order for the above substances to fully reveal their beneficial features they are subjected to special treatment. So, in the process of producing euroslate, materials are pressed, which is carried out in several stages in vacuum chambers. The result is a material that has a multilayer structure and has all the properties listed above.

Euroslate - ondulin

As you probably already understood, Euroslate does not contain any substances hazardous to human health, so the roofing material in question is environmentally friendly. In addition, it is worth noting that ondulin, if necessary, can be easily processed.

So, euroslate differs from ordinary slate in that it has a wide variety of colors and shades. Currently, manufacturers produce ondulin with two color classes: matte and glossy. Matte ondulin has a somewhat rough surface and is covered acrylic paint. Gloss ondulin is given due to the fact that in coloring composition silicone is added. As a result of this, the euroslate not only takes on a presentable and varied in color appearance, but also additional useful properties. In particular, on a glossy onduline, snow and water linger to a lesser extent than on a matte one.

Convenience of laying ondulin

Sheets of euroslate are produced in the size of two square meters. This makes it possible to install sheets on a large area for a short time. Even more productivity can be added by the fact that euroslate can be laid on top of the previous roofing material, thereby eliminating the need for dismantling works old roofing material. If ondulin is laid on a new roof, then before laying it, it is necessary to assemble the crate.

Characteristics of euroslate sheets from various manufacturers

Euroslate is very easy to work with, as this material is easy to process and has a low weight. For example, if during the installation of ondulin on the roof you need to cut it, then you can do this with a regular hacksaw or an improvised power tool. In addition, ondulin sheets can be easily bent, thereby creating a rounding with a radius of at least five meters. In order for you to be able to cover the roof of any complexity with the help of euroslate, manufacturers produce a wide variety of additional elements.

When looking at euroslate, it may seem to you that this is a fragile and fragile material, but in fact this is far from the case. As the operating experience of the roofing material in question shows, it is able to withstand a snow load of three hundred kilograms per square meter surfaces. In addition, euroslate sheets are able to successfully resist ultraviolet radiation, that is, over time, the color of euroslate does not change under the influence sun rays. Thus, after installation, ondulin will absolutely not need maintenance and repair. You do not have to paint the roof, replace damaged sheets, and moisture and snow will roll off the roof by themselves.

Features and rules for mounting euroslate

Euroslate is a roofing material that is convenient and easy to use, which is why it is quite possible to lay euroslate on your own. The main thing is to keep a few simple rules and as a result you get an attractive looking roof with excellent performance properties.

Before proceeding with the installation of euroslate, it is necessary to calculate how much material you need to work. When calculating the number of sheets of ondulin, it is necessary to take into account not only the area of ​​\u200b\u200bthe roof, but also the fact that the ridge must cover the roofing material at a distance of at least 18 centimeters.

In addition, do not forget that the euroslate sheets will overlap, so you will need more sheets than might be expected from the area of ​​the roof. Also, do not forget that the slate is attached to the crate with nails, which will also have to be purchased from required quantity. As a rule, nails are nailed into the slate every two waves and, based on this, it is quite easy to calculate how many nails you need to carry out the work.

The sequence of laying euroslate sheets. Consider the most frequent wind direction when laying slate

How to properly assemble a crate for euroslate

Euroslate is attached to the crate, and the better it is assembled, the more successfully the slate will lie on the surface. Here, first of all, it is worth paying attention to the fact that the roof slope is best done at an angle of at least 14 degrees. In this case, the lathing beam is fastened in increments of 60 centimeters, while it should be borne in mind that when covering the roof with slate, you can use smaller sheets, respectively, the step with which the lathing beams are located should be smaller. That is, the smaller the euroslate sheet, the smaller the step.

It is far from always possible to give the roof slope an angle of more than 14 degrees, in some cases design decision construction of a more gentle slope is envisaged. In this case, the battens of the crate are mounted in increments of at least 45 centimeters. This is due to the fact that more load is placed on a less sloping roof, respectively, if you make a rare crate, then in winter it can simply collapse under a mass of snow.

Similarly, more frequent lathing should be done if there are any roundings on the roof. In order for the roof to be able to successfully withstand loads in places of rounding, the crate should be made more frequent. Separately, it is worth mentioning that the construction of the crate should not be carried out at a temperature below - 2 degrees, since wood at low temperatures significantly changes its properties and as a result of this, when installing the crate, you run the risk of splitting the timber.

How to work with euroslate

When working with euroslate, you will inevitably need to cut or saw it out. Slate sheets can be cut with the most ordinary hacksaw, the cut is even, and the sheet itself is sawn quite easily and quickly. But when it comes to roofing large area, then a hacksaw in this case will be clearly inappropriate, it is more advisable to use a power tool. For example, when cutting euroslate sheets, it has proven itself well a circular saw with hard-alloy nozzles on the cutting disk.

Covering the roof, in any case, you will move along the surface of the roof, walk on the slate, and at this moment the roofing material can be easily damaged. To avoid this, wear soft-soled shoes while working.

In addition, you may have problems removing improperly hammered nails. As you know, nails in slate are hammered into a wave, while pressing on a sheet of slate, the nail head should not protrude above the material. If you needed to remove a hammered nail, then for this, take a piece of a bar, such pieces, after the construction of the crate, there will probably be a lot on the construction site. The bar must be placed in the cavity of the wave and resting the nail puller on it, remove the nail from the slate sheet, while being careful.

Don't Forget Roof Ventilation

When attaching euroslate sheets, do not forget that the roof must have natural ventilation. What is it for? The thing is that during the operation of the roof, warm air from the house will rise to the roof, where it will meet the cold outdoor air. It is clear that as a result of mixing warm and cold air, condensation forms, which settles on the crate.

What does this lead to? This leads to the fact that the wood of the crate will begin to rot and very quickly lose strength and, as a result, the roof will collapse. This can happen quite quickly, so when laying euroslate, do not forget about ventilation. Usually, ventilation holes arrange under the lower slope of the roof, creating a kind of kink with the help of additional elements. This fracture, in addition to ensuring ventilation of the crate, also contributes to the fact that moisture from the roof will not go to the walls of the house, but will accumulate in the drains and be discharged to where you need.

How to ensure the tightness of the roof

When laying a roof with any roofing material, and Euroslate is no exception, one of the main tasks is pursued - making the roof tight. No matter how wonderful the roofing material is, if cracks form at the joints during flooring, then there will be no benefit from such a roof. Therefore, when laying euroslate, it will not be superfluous to be guided by the following points.

When laying the roof, do not neglect the additional elements, due to which, for the most part, the tightness of the roof is ensured. Additional elements will help you close the ends of the roof, the ridge, redirect the moisture that gets on the roof in the direction you need.

In addition, during the slate flooring, do not forget to trim the corners. Why is it necessary? The thing is that the slate sheets are overlapped and as a result, seams are formed. thick. Snow will begin to accumulate under these seams, which from the heat rising from the side interior spaces will hide at home. Accordingly, even though you will ensure the tightness of the joints with the help of additional elements and the tight fit of the euroslate sheets to the crate, nevertheless, water will seep under the roof. In order to prevent this from happening, the corners on the slate at the junction are cut. Due to this, the thickness of the seam is significantly reduced and the snow has no chance to penetrate under the roof.

Separately, it is worth mentioning the drainage system. This system necessary so that the water flowing from the slate does not fall on the walls of the house. As a rule, drains are suspended under the roofing material in such a way that moisture from the lower waves of the slate falls directly into the drain. By by and large constructing a competent drain is not difficult, but for some reason many homeowners use the cheapest drains that have an unpresentable appearance and low anti-corrosion properties. Because of this, the attractive appearance of euroslate deteriorates, which is clearly unacceptable. From this we can conclude that the additional elements and the drain should have no less presentable appearance than the euroslate itself. For example, additional elements and drainage elements made of galvanized steel coated with a polymer will be well combined with euroslate.

bituminous wavy sheets- These are organic fibers impregnated with bitumen. Formed into a ten-wave sheet from a homogeneous mixture of organic and inorganic fibers, they have a multi-layer tightly compressed construction that guarantees good resistance to deformation upon impact.

With front side sheets are covered with a protective and decorative paint layer based on polymers and light-resistant pigments. The surface treatment with high-density acrylic increases the durability of the roofing sheet, and also protects it from the ultraviolet radiation of the sun, wind and rain. Due to its coating, bituminous corrugated sheets (Euro slate) have such a surface structure that dirt from the atmosphere that has settled on the roof is removed by rain and sliding snow. For decorative design roofing offers several options for coloring sheets.

Euroslate is used not only in new construction, but also for repairing old roofing by laying new roofing sheets on it without removing the old roof. Euro slate laying does not require any special preparation. The material is easy to cut hand saw and fastened with special nails with a sealing cap. One person is enough to install the euroslate.

On the Russian construction market, there are materials from several manufacturers of corrugated bitumen sheets (Fig. 13) with similar dimensions and technical characteristics.

Rice. 13. Bituminous corrugated sheets and fittings

When installing euroslate, follow the instructions of the manufacturer of the material, paying special attention to the requirements for the crate. Otherwise, the installation of bituminous corrugated sheets from various manufacturers is not much different.

Typically, corrugated bituminous sheet roofing on flat roofs with a pitch of 5 to 10° (1/11 to 1/6) requires continuous sheathing of planks, moisture-resistant plywood, or OSB boards(OSP). Term continuous crate from the boards does not mean at all that the boards should be tightly pressed against each other, on the contrary, when laying between them, a gap of up to 5 cm is left. butt The overlap of euroslate sheets on each other with such a slope is equal to 300 mm, the side overlap is 2 waves.

On roofs with a slope of slopes from 10 to 15 ° (from 1/6 to 1/4), a crate of wooden bars with a section of 40 × 50 (h), 50 × 50 mm and an installation step of 45 cm along the axes is needed. In this case, the front overlap of the sheets is 200 mm, the side overlap is 1 wave.

Roofs with slopes of 15° and above (from 1/4 and less), the step of the lathing bars can be increased up to 60 cm along the axes. Frontal overlap - 170 mm, side - 1 wave (Fig. 14). In areas with a heavy snow load or with potentially large snow drifts on the roof, the interval between the laths of the battens should be left the same - 45 cm. If there is any doubt, it is recommended to further reduce this interval.

Rice. 14. Lathing under euroslate

The crate is made with an overhang a little longer than required. For precise positioning of the pitch of the lathing bars, a template cut from the lath trim is used. Eaves overhang roofing is provided by a filly - a board nailed to the lower end rafter leg. Thus, on gable roofs with an overhang of laths and a filly length, it is possible to reduce or increase the size of the entire roof slope, adjusting it to the most favorable cutting of the roof. For example, knowing usable area covering one roofing sheet, the size of the roof slope can be adjusted so that the number of cuts is minimal or so that the cuts can be used on another slope. Therefore, during the construction of the roof, it is better to make laths and fillies longer than required, then it is easier to saw off the excess than to build up the missing one.

for roofs complex shapes cutting of the roof is done in special computer programs with the call of the measurer on the object. For simple roofs, it can be done on graph paper and tracing paper (Fig. 15). To do this, the position of the roofing sheets is drawn on graph paper, and the plan of the roof slope is drawn on tracing paper. Tracing paper is superimposed on graph paper and shifted along it until the optimal solution is found. When predicting the cutting of hip roofs, you need to make sure that the top of the corner sheets is on the lath, otherwise it will be difficult to fix them, you will have to install bars with hemming along the edge of the hip. Along the length of the slope, cut sheets can be placed both at the cornice and at ridge knot. According to the width of the slope, as an option, you can not stack a whole number of sheets with a remainder on the edge, but cut one sheet lengthwise and put it in the center or any other place in the row, then the last sheet of the row will turn out to be wider and fit well on the crate.

Unsuccessful cutting, corner sheets do not lie on the crate

Unsuccessful cutting, a lot of illiquid scraps

Successful cutting, corner sheets lie on the crate, and trimmings can be used on another slope

Rice. 15. An example of cutting a slope of a hip roof

Euroslate manufacturers recommend starting the second row of roofing sheets with a sheet cut in half, in which case a good “run-up” of overlaps is obtained. However, this is true only for rectangular slopes, on which an integer number of sheets is obtained in the first row. If a hip roof is made (with trapezoidal slopes) or a gable roof (with rectangular slopes), on which an integer number of sheets does not fit, you can deviate from this rule. Both the first and second rows can be started with a sheet cut along the width of which will give the least amount of waste along the entire slope. The main thing is that the overlap of the second row is not combined with the overlap of the first row, otherwise it will have four layers of roofing. If the combinations longitudinal edges cannot be avoided, then the corners of the roofing sheets are cut off (Fig. 12). In this case, when predicting cutting on tracing paper, it is better to draw roofing sheets, and on graph paper the roof slope. Apply tracing paper to graph paper and move until there is best option cutting.

Before laying the sheets on the roof, the squareness of the gable slopes is checked or marked, which is more desirable (Fig. 16). On the hip roofs in advance, even at the device truss system, you need to try to make the angles of inclination of the hip ribs the same. This is provided correct markup and laying Mauerlat beams and girders. Only the same angles of inclination of the hips allow waste-free use of trimmings on opposite slopes.

Rice. 16. Checking or marking the right angles of the roof slopes and a way to eliminate small errors

The squareness of the slopes is checked (marked) using the right triangle formula: the length of the hypotenuse should be equal to square root from the sum of the squares of the legs. To check (mark) right angles, you can put together a right-angled triangle with sides: legs - 3 and 4 m, hypotenuse - 5 m or legs 1.5 and 2 m, hypotenuse - 2.5 m. You can not make a triangle, but use two roulettes : alternately postponing the legs and checking the length of the hypotenuse. It’s hard to say what to give preference to, climbing on the roof with both tape measures and triangles is not very convenient. After determining the squareness of the roof slopes, the trim lines are “beaten off” with a coated thread, the “extra” length of the laths and fillies is sawn off. Euroslate manufacturers allow some deviation of the slopes from right angles. Euroslate flexible material, so it can be slightly stretched or compressed, like accordion furs, but not more than 2% of the original width. For sheets with a width of 950 mm, this is no more than 2 cm, for sheets with a width of 1220 mm - 2.5 cm.

Installation of the roof is done towards the prevailing winds () at positive temperatures. The bitumen with which the sheet is impregnated "does not like" frost, the sheet becomes hard and brittle. Bitumen also “does not like” the scorching sun, the sheet becomes too soft and supplely changes shape when nailed too tightly.

To install the first sheet on a rectangular roof, mark the width of the roofing sheet from the corner along the eaves and make a mark with a colored pencil. Then measure the same width and mark along the roof ridge. Mark off a chalk line connecting these two marks. To determine the length of the free roof overhang over the eaves, drive nails into the corner rafters and stretch the twine from corner to corner at a distance of 4.5–7 cm from the eaves along its entire length. It is necessary to make a reservation here, different manufacturers of euroslate recommend different sizes of free overhang for their sheets, which range from 4.5 to 7 cm. This value depends on the thickness of the corrugated bitumen sheets. Adhere to the free eaves recommended by the roofing manufacturer. If the overhang is made larger, then the edge of the roof will bend down either under the weight of snow or under the scorching sun.

Lay the first sheet, aligning it with the string stretched from corner to corner and the chalk line. If the roof slope is rectangular, the sheet will align well with them, it must be immediately fixed with nails. If the ramp is not rectangular, align the sheet along the cord and nail it in one wave along the length of the sheet, and stretch or compress the other side, aligning the sheet along the edge of the slope or along the chalk line. It is desirable that the chalk line be perpendicular to the lace stretched along the eaves, then aligning the first sheet along the chalk line and lace and pulling it aligned to the edge of the slope, this procedure will not be required anymore, the remaining sheets of the first row will lie flat, they will need to be leveled only along shoelace. When using wind corners in the roof, it is not required to level the edge of the sheets along the edge of the slope, small errors in the squareness of the slope will be covered by the wind corner.

Corrugated bitumen sheets are fastened in a strict sequence (Fig. 17): first, the edges of the sheet are fastened, then the middle, then the rest of the nails are finished. The sheets are flexible, if this sequence is not followed, then by accidentally constricting a heavily hammered nail, you can change the geometry of the sheet. For example, if you consistently drive nails alternately into each wave of a sheet, then with heavily hammered nails you can roll it into a “pancake”. Compliance with the rule of order of fastening will “forgive” an inadvertently heavily driven nail. Nails are not hammered into the last crest of the wave (or into the last two crests), it will go under the overlap of the second sheet and will be fixed when this sheet is fastened. Nails are not hammered in the upper part of the sheet either, there will be an overlap with sheets of the second row, followed by fastening. If a corner wind corner is used, then the nails are not driven into the crest of the first wave, it will be fixed together with the installation of the wind corner fitting. The corner fitting is fastened with nails or fixing screws through the flange of the fitting and the crest of the sheet wave to each lath.

Rice. 17. Rules for installing corrugated bitumen sheets (circles show the sequence of driving nails into sheet waves)

In the first and last sheet of the row, nails are driven through the extreme wave into each lath and through each crest of the sheet wave into the lower lath; in the middle of the sheet, nails are driven through the wave and through the lath. 22 nails are driven into an ordinary ten-wave sheet of the roof with a lath spacing of 45 cm. The first row of nails is driven into each wave crest, then in a checkerboard pattern.

The second and subsequent sheets of the first row are installed with alignment along the cord, which regulates the amount of free overhang. With especially high-quality work, for each subsequent sheet of a row, a chalk line is beaten off from the eaves to the ridge, perpendicular to the cord and regulating the width of the sheet. These lines will not visually allow you to drag the roofing sheets with strong nailing and change their geometric dimensions.

The second row of sheets begins with a sheet cut along, dividing it into two or more parts, if required by cutting the roof. The main purpose of cutting the first sheet of the second row: to avoid overlap a large number layers, secondary - aesthetic, make longitudinal joining seams in a checkerboard pattern. Although at a great distance, namely from there, you can see the roof, the side joints of the sheets are almost invisible. The sequence of installing sheets of the second row is the same as that of the first: the coated line is beaten off, the sheet is leveled along it and nailed. It is necessary to monitor the amount of overlap, it must correspond to the slope of the roof. If the battens of the crate were set carefully and according to the template, then the overlap will be obtained automatically.

Sheets are cut along the length with a sharp cutter along the wave cavity. Width cutting is done with a wood saw with an oiled blade or electric saws: circular or jigsaw. It is better not to use a grinder with emery discs, they will melt the bitumen. Nails are hammered only into the crest of the wave perpendicular to the crate. An unsuccessfully hammered nail is pulled out with a lining under the stop of the nail puller, cutting a pipe with a diameter approximately equal to the depth of the wave of the sheet (Fig. 18).

The prichelina, in the place of the side overhang of the roof over the gables, is designed in two ways: using a corner fitting and bending the roof on wind board(Fig. 19). The second method is recommended to be done only in warm weather when from solar heating euroslate sheets become soft, or the roof overhang needs to be heated with hot air from a building hair dryer.

Roof adjunctions to walls, valleys and ridges are made in the same way as on roofs made of asbestos-cement corrugated sheets using shaped parts attached to euroslate. The difference in the work is that the fastening of the euroslate style is made in each crest of the wave of roofing sheets or in each lath. Once again, we recall that, unlike hard asbestos-cement slate, euroslate is a soft material, which is why so many nails are driven in. In addition, special self-adhesive waterproofing tapes are made for euroslate, thanks to which there is no need to create niches in the walls and bricks on pipes (Fig. 20. However, waterproofing tapes do not exclude the use of traditional roof junctions to walls and pipes. On the contrary, sharing in these knots of niches, brick overlaps and waterproofing tapes increases the reliability of the roof.

Fractures of the roof slopes are arranged using isosceles corner parts. One shelf of which is brought under the roof of the upper slope, the other is put on top of the roof of the lower slope (Fig. 21).

For the ventilation of the under-roof space, depending on the roof structure, breathable linings can be installed under the bituminous corrugated sheets. Their use will provide penetration under the roof air masses and drying inner surface roofs, battens and rafters, while limiting the entry of birds and insects under the roof.

Bituminous corrugated sheets have several names - bituminous sheet, bituminous slate or euroslate. This is one of the most popular and cheapest roofing materials. AT last years the volume of suburban and industrial construction has increased significantly, where the use of bitumen sheets is very popular. This is due to the relatively low price compared to metal or flexible tiles, and the fact that it did not affect the service life of this coating. It will easily last 15-20 years, during which time the building codes and space requirements. You won't have to regret spending a lot of money on roofing, and when a new, better and more aesthetic technology appears, you can easily change it.
Bituminous sheet is lighter than other materials and practically waste-free. Due to its low weight, it can be laid directly on the previous roof without dismantling it.
To appreciate the main qualities of this roof, you need to understand what it is. This is a cellulose base with resin additives, which was impregnated with high temperature and under pressure with a special bituminous composition with the addition of minerals and pigments, painted with a vinyl or acrylic polymer and dried. As a result of this process, an environmentally friendly material is obtained, which, unlike metal analogues, does not rust.
