Recently, shingle roofing has become very popular among developers. This roofing has an attractive appearance that is not inferior in beauty to traditional tiles, a long service life and high moisture resistance. Thanks to the self-adhesive layer on the back of the shingle, do-it-yourself soft roofing can be done even without professional experience. In this article we will tell you how to properly prepare the base, assemble the crate and lay flexible tiles.
Flexible tiles are called tiles with a figured edge, made of fiberglass impregnated with modified petroleum bitumen. Laid with an overlap, such a roof imitates a rare, but aesthetic shingle covering made of wooden chocks. Fiberglass, which is part of bituminous tiles, can be plain or reinforced with polyester. The technology for the production of this material includes sprinkling the front side with armoring dressing made of stone or basalt chips, which gives color and a rough texture to the roof. The advantages of flexible tiles are:
- Durability. The service life of a soft roof based on polyester-reinforced fiberglass is more than 70 years, which fully pays for the cost of installing a roof.
- Weather resistance. The soft tile maintains influence of atmospheric moisture, ultra-violet rays and other adverse environmental factors, keeping operational qualities.
- Aesthetics. A variety of shapes and colors of the material opens up great opportunities for creating a harmonious, integral image of the house.
- Flexibility. Flexible, elastic bituminous tiles are suitable for arranging roofs of complex shape with a large number of slopes, valleys and other decorative elements.
Important! The technology of laying bituminous tiles is distinguished by its simplicity, therefore it can be easily performed even by a non-professional. Do-it-yourself soft roofing is an excellent solution for the roof of a private house, country cottage, gazebo or townhouse.
Features of working with the material
Before you cover the roof with a soft roof, you need to make sure that a reliable foundation has been prepared for work. Also, the technology of installing a soft roof involves the performance of work subject to certain weather conditions. If you do not follow the manufacturer's recommendations, you may encounter the following problems:
- If bituminous tiles are laid at an ambient temperature of less than 5-10 degrees, then the self-adhesive layer on the back of the tiles does not melt on its own. To melt the bitumen, you have to use a gas burner or a building hair dryer. However, this makes it difficult and slows down the laying of tiles.
- If you lay shingles at temperatures above 25 degrees, the self-adhesive bituminous layer melts too much and flows down the slope. In addition, high temperatures lead to deformation of the roof.
- If you install the roof in wet weather or during rain, the rafter frame and lathing acquire excess moisture, which negatively affects the life of the tile, leading to decay.
Important! The material installation technology recommended by the manufacturers prescribes installation at a temperature of 5-15 degrees in dry weather. Most often, such conditions develop only in the summer. However, in winter, you can assemble the truss frame for the roof and prepare the base for the roofing deck.
Lathing installation
Before you make a soft roof, you need to assemble a high-quality, durable crate. The technology of laying bituminous tiles involves the use of a solid base, which gives rigidity and mechanical strength to the soft roofing. The lathing should ensure an even distribution of the weight of the roof between the rafters, so it is created from 3 layers:
- Control grid. The counter-lattice for soft tiles is made of wooden bars 3-4 cm thick. It is attached along the rafters of the frame over the waterproofing material. The task of the counter-lattice is to create a ventilation gap between the rafters and the roofing.
- Sparse crate. This base element for soft tiles is made from edged boards measuring 20x150 mm. The boards are nailed perpendicular to the counter-lattice at a distance of 30-50 cm.
- Solid crate. It is made of moisture-resistant plywood, OSB sheets or edged boards, laid solid with a gap of 1-3 mm, which compensates for the thermal expansion of the material. To prevent damage to soft tiles, it is necessary to sand or trim the elements of the crate so that they are smooth.
Please note that for the manufacture of lathing for a soft roof, it is correct to use dried up to 20 percent softwood. To prevent premature decay of wooden elements, they are treated with antiseptic preparations. If the structure has a high risk of fire, then the crate is impregnated with fire blocking compounds.
Lining carpet
Do-it-yourself soft roofing is laid on a solid crate made of chipboard or moisture-resistant plywood. A lining carpet is laid on top of the base - a lining made of moisture-resistant bituminous material resistant to mechanical damage. The lining carpet protects the roof from leaks, as well as from damage to the shingles by uneven lathing. Coating installation technology recommends:
- With a roof slope of less than 15-18 degrees, lay a lining carpet on the entire surface of the slopes with an overlap of 15-20 cm, since water can linger on it during the melting of large snow masses.
- At an angle of inclination of the slopes of more than 20 degrees, the lining carpet can only be laid in places that are particularly vulnerable to leaks, where water can accumulate or stagnate. Additional waterproofing protects the valleys, the joints of the slopes with vertical surfaces, the ridge.
- Do not use ordinary roofing material as a lining. The low price does not compensate for the poor quality, fragility and short service life of this material.
Experienced craftsmen advise using the material recommended by the manufacturer as a lining carpet, as it is guaranteed to be compatible with the selected shingles.
Laying
Do-it-yourself installation of a soft roof is carried out in dry, calm weather at a temperature of 5-15 degrees. If the material is laid on an old truss frame, then it is necessary to check the condition of the wood, and then replace the rotten or deformed elements. Installation is carried out in the following order:
- First, the slope is marked with horizontal stripes, marking the location of the rows of soft roofing with white chalk.
- It is correct to start laying the material from the bottom of the slope, using the starting strip. Fix the roofing with nails or a self-adhesive layer. If the tiles are self-adhesive, then to stick them, it is enough to remove the protective film, and then attach it tightly to the roof base.
- If nails are used to fix the coating, then they must be placed no closer than 2.5 cm from the edge, and also driven flush with the surface of the material.
- The second row begins to be laid on the left side of the slope with the help of tiles, from which 143 mm are cut off from the left edge, thus shifting the bituminous tile pattern diagonally.
- To start the third row from the tile, a fragment 286 mm long is cut off from the left edge in order to also shift the coating pattern in a diagonal direction.
- After completion, a ridge is formed using a ridge element, junctions with vertical surfaces and valleys.
Note! In order for a roof made of soft tiles to function correctly, it is necessary to equip a ventilation system to avoid the "greenhouse effect" and rotting of the truss frame of the structure.

The appearance on the market of roofing materials of soft tiles has greatly simplified the process of covering roofs of complex configuration. This is the only high-quality material that has flexibility and plasticity; it can be used to quickly and tightly cover all types of roofs, including domed ones. At the same time, the amount of unproductive waste is minimal, which cannot be said about other roofing materials. The service life of some types of flexible tiles reaches fifty years, however, such material is not much different in cost from piece coatings of the elite segment.
The reliability and durability of a roof is equally dependent on several factors.
- Technical characteristics of soft tiles. You should pay attention not only to the appearance, this parameter affects only the appearance of the building and is not related to the durability of operation. Buyers should find out what kind of base was used by the manufacturers, what is the chemical composition of the bitumen and what is its thickness. Bitumen must be modified to increase protection against ultraviolet rays, increase plasticity at sub-zero temperatures and resistance to mechanical stress. The base must be chosen the most durable of polymer fibers.
- The quality of the rafter system. If the structure staggers, has uneven planes, load-bearing units do not meet maximum loads, then the roof will not be airtight. Over time, due to numerous fluctuations, mechanical damage or delamination will appear. This applies to all roofing materials, not just soft tiles.
- The professionalism of the roofers. No matter how high-quality the roofing material is, the inept actions of the builders neutralize all its advantages. Builders must not only know the theory perfectly, but also have extensive practical experience. Freestanding roofers can make their own decisions depending on the situation, it is impossible to foresee all the problems in advance. In addition, responsible craftsmen will never deviate from the recommended technology in order to save time.
All roofing work on laying soft tiles consists of several stages, the high-quality performance of each of them affects the reliability and durability of the roof.
Depending on the complexity of the rafter system and the purpose of the building, some steps can be skipped. The table gives the most complete list of construction activities for the most complex roofs.
| Stage name | Composition and brief description of features |
|---|---|
| Soft tiles require a solid base, which can be made of waterproof plywood, OSB boards or edged boards. In each case, an individual option is selected, taking into account the complexity of the roofing system, the category of the building and the financial capabilities of the developers. You need to know that in some cases the cost of preparing the base and the price of the materials used for this may exceed the cost of soft tiles. |
| The lining layer performs two functions: it serves as an additional waterproofing of the roof and increases the reliability of fixing shingles of soft tiles. For the lining layer, you need to buy special modern materials, installation is carried out from the bottom up or vertically with an overlap of about ten centimeters. If the angle of inclination of the slopes is small, then it is recommended to seal the joints with bituminous mastics. |
| Valleys require increased attention, it is here that the largest volume of water is concentrated and leaks most often appear. To equip the valleys, manufacturers produce special materials that are fixed at the junction of two slopes. The same technology is also used during sealing of chimney junctions, vertical brick architectural elements or various engineering communications. The materials used must have relatively large plasticity characteristics to compensate for the linear vibrations of architectural structures made of various building materials. |
| Installation of soft tiles does not require much physical effort, but the work must be treated very carefully. Any violations of technology will necessarily have negative consequences, the elimination of which requires time and material losses. There are times when repairing the roof of a house is more expensive than installing tiles: you have to restore the truss system, eliminate the consequences of leaks in the interior living quarters, etc. |
Before proceeding with the installation work, you should prepare the tools and draw up a preliminary plan of action.
The roof made of bituminous soft tiles is easy to use, durable and aesthetic. Its big plus is that self-assembly is quite possible. The technology is not the most complicated, the weight of the fragment is small, it is attached to the adhesive base, additionally fixed with roofing nails. So the installation of soft tiles with your own hands can be done even alone.
Roofing cake for soft tiles
The attic under the roof can be warm or cold, depending on this, the composition of the roofing cake changes. But its part from the rafters and above always remains unchanged:
- waterproofing is stuffed on the rafters;
- on it - bars with a thickness of at least 30 mm;
- solid flooring.
Here we will consider these materials in more detail - from what and how to make, what features each of them has.
Waterproofing
Waterproofing membranes are available in one, two or three layers. Single-layer membranes - the simplest and cheapest, perform only a dual task - do not allow moisture to pass towards the room and release vapors to the outside. In such a simple way, the attic is not only protected from the penetration of condensate or suddenly leaked precipitation, but also excess moisture that accompanies human life is removed from the air. Single-layer membranes are poorly represented on the market. Practically they are produced by one company - Tyvek.
Two and three-layer membranes are more durable. They, in addition to the waterproofing layer, also have a layer that gives greater tensile strength. The third layer, if any, is the absorbent layer. That is, even if a drop of condensate has formed on the surface of the membrane, this layer absorbs it into itself, preventing it from spilling onto other materials. With sufficient ventilation, moisture from this layer gradually evaporates and is carried away by air currents.
Three-layer membranes (for example, EUROTOP N35, RANKKA, YUTAKON) are desirable if your attic is insulated and mineral wool is used as a heater. It is afraid of getting wet and with an increase in humidity by 10% loses half of its thermal insulation properties.
If there is a cold attic under the soft tiles, it is advisable to use a two-layer waterproofing membrane. In terms of strength, it is much better than single-layer ones, and at a price it is only a little more expensive.
crate
On top of the waterproofing film, parallel to the overhang, the lathing strips are stuffed. They are necessary to create a ventilation gap. It will help maintain the normal humidity of roofing materials.
The crate is made of coniferous boards (mainly pine). The thickness of the boards is at least 30 mm. This is the minimum gap that will ensure the normal movement of air in the under-roof space. Before laying, the wood must be treated with an impregnation that protects against pests and fungi; after drying this layer, it is also treated with flame retardants, which reduce the combustibility of wood.
The minimum length of the board for the crate is at least two spans of rafters. They are attached and connected above the rafter legs. You can't connect them anywhere else.
Flooring
The flooring under soft tiles is made solid. Materials are selected based on the fact that nails must be driven into it, therefore they are usually used:
- OSB 3;
- moisture resistant plywood;
- tongue-and-groove or edged board of the same thickness (25 mm) with a moisture content of not more than 20%.
When laying flooring under soft tiles, it is necessary to leave gaps between the elements to compensate for thermal expansion. When using plywood or OSB, the gap is 3 mm, between edged boards 1-5 mm. Sheet material is fastened with a run-out of seams, that is, so that the joints are not continuous. Fasten the OSB with self-tapping screws or ruffed nails.
Using boards as flooring, it is necessary to ensure that the annual rings of the wood are directed downwards. With the reverse arrangement, they will be arched, soft tiles will be lifted, the tightness of the coating may be broken. There is another trick that will keep the wooden flooring even if the moisture content of the boards is above 20%. When laying the ends of the boards, they are additionally fastened with two nails or self-tapping screws hammered close to the edge. This additional fastener will prevent the boards from bending during shrinkage.
The choice of the thickness of the material for flooring under soft tiles depends on the pitch of the crate. The larger the pitch, the thicker the flooring required. The best option is a frequent step and thin plates. In this case, a light but rigid base is obtained.
Another point concerns the installation of flooring for soft tiles around the chimney pipe. With a brick pipe, the width of which is more than 50 cm, a groove is made behind it (pictured). This design, reminiscent of a mini-roof. It separates the rain streams, they roll down the sides of the pipe without flowing into the under-roof space.
After installing the flooring, its geometry is checked. The length is measured, the width of the slope at the top and bottom, the height of the slope on both sides, the diagonals are measured. And the last check - tracking the plane - the entire slope must lie entirely in the same plane.
Soft tile roofing technology
When buying, you will most likely be provided with instructions, to which the installation of soft tiles will be described step by step and in detail, indicating all the exact dimensions that this particular manufacturer requires. These recommendations should be followed. However, it is worth getting acquainted with the order of work and their volumes ahead of time - in order to understand the intricacies of installation and the required amount of materials.
We must say right away that it is necessary to handle soft tiles when laying carefully - she does not like it if she is bent. Therefore, try not to bend or crush the shingles unnecessarily (this is one fragment consisting of a visible and mounting part).
Overhang reinforcement
The drip bar is installed first. This is an L-shaped sheet of metal coated with paint or polymer composition. Polymer coating is more expensive, but also more reliable. The color is selected close to the color of bituminous tiles.
Drip bar installed along the roof overhangs
The task of the drip bar is to protect the crate, sections of rafters and flooring from moisture. With one edge, the dropper is laid on the flooring, with the second it closes the overhang. It is fastened with galvanized (stainless steel) nails, which are hammered in a checkerboard pattern (one is closer to the fold, the second is almost at the edge). Fastener installation step - 20-25 cm.
The drip bar is sold in two-meter pieces. Having laid the first element, the second is fixed with an overlap of at least 3 cm. If desired, the gap can be closed: grease the joint with bituminous mastic, fill it with sealant. At the same stage, it is mounted, in any case, hooks are nailed that will hold the gutters.
Laying waterproofing carpet
Regardless of the angle of the roof, a waterproofing lining must be laid in and along the slope. It is sold in meter wide rolls. An adhesive is applied to the underside, covered with a protective film or paper. Before laying, the paper is removed, the valley carpet is glued to the flooring.
Installation of a waterproofing carpet begins with laying it in the valley. Roll out the material of a meter width, distributing 50 cm on both sides of the bend. Here it is desirable to do without joints, but, if necessary, the overlap of two canvases should be at least 15 cm. Laying goes from bottom to top, the junction is additionally coated with bitumen mastic, the material is well pressed.
Next, a waterproofing carpet for flexible tiles is laid along the cornice overhang. The minimum width of the carpet on the cornice overhang is the size of the overhang itself, plus 60 cm. First, the carpet is rolled out, if necessary, cut, then the protective film is removed from the inside and glued to the substrate. Additionally, they are fixed along the edges with stainless steel or galvanized nails with a large flat hat (step 20-25 cm).
In places of a horizontal joint, the overlap of two canvases is at least 10 cm, in the vertical direction - at least 15 cm. All joints are additionally coated with bituminous mastic, the material is compressed.
Lining carpet
The lining carpet, as well as the waterproofing carpet, is sold in rolls of meter width, the back side is covered with an adhesive. The laying method depends on the slope of the roof and on the profile of the selected shingles.
When using shingles with cuts (such as Jazz, Trio, Beaver tail), regardless of the slope, the lining carpet is spread over the entire surface of the roof.
Underlayment installation often requires undercutting. This is done with a sharp knife. In order not to damage the material below when cutting, enclose a piece of plywood or OSB.
Fronton (end) plank
Gable strips are mounted on the side sections of the overhangs. These are strips of metal bent in the form of the letter "G", along the fold line of which there is a small protrusion. They cover the laid roofing materials from wind loads, from moisture ingress. The gable plank is laid on the flooring over the lining or waterproofing carpet, fixed with nails (stainless steel or galvanized) in a checkerboard pattern with a step of 15 cm.
These planks also come in pieces of 2 m, stacked with an overlap of at least 3 cm.
Slope marking
To make the installation of soft tiles simple, markings in the form of a grid are applied to the lining carpet or flooring. Do this with a painter's cord. The lines along the cornice overhang are applied at a distance equal to 5 rows of tiles, in the vertical - every meter (the length of one flexible tile shingle). This marking makes laying easier - the edges are leveled along it, it is easier to track distances.
Valley carpet
On top of the already laid waterproofing carpet, another valley material is laid. It is slightly wider, serves as an additional guarantee of no leaks. Without removing the protective film from the underside, it is laid, cut at the bottom in the overhang area, and the boundaries are marked. Deviating from the mark of 4-5 cm, a special mastic of increased fixation Fixer is applied. It is applied from a syringe, with a roller, then rubbed with a spatula into a strip about 10 cm wide.
A valley carpet is laid out on the mastic, the folds are smoothed out, the edges are pressed. Stepping back from the edge by 3 cm, it is fixed with nails in increments of 20 cm.
Connection to a brick pipe
To bypass pipes and ventilation outlets, patterns are made from a valley carpet or galvanized metal, painted in the appropriate color. The surface of the pipe is plastered, treated with a primer.
When using a valley carpet, a pattern is made so that the material enters the pipe by at least 30 cm, and at least 20 cm should remain on the roof.
The pattern is smeared with bitumen mastic, placed in place. the front part is installed first, then the right and left.
Part of the side elements is wrapped on the front part. The back wall is installed last. Its parts go to the side.
With proper installation on the flooring around the pipe, a platform is obtained, completely covered with a valley carpet. Before laying tiles in this place, the surface is smeared with bituminous mastic.
The tile from three sides enters the laid carpet, not reaching the walls of the pipe 8 cm.
The upper part of the junction is sealed with a metal strip, which is attached to the dowels.
All gaps are filled with heat-resistant sealant.
Conclusion of round pipes
For the passage of ventilation pipes there are special passage devices. They are positioned so that the lower edge of the element extends over the tile by at least 2 cm.
Having attached the passage element to the roof, its inner hole is circled. According to the applied contour, a hole is cut in the substrate, into which a round pipe is led out.
The back of the skirt of the passage element is smeared with bituminous mastic, set to the desired position, and additionally fastened around the perimeter with nails. When installing soft tiles, the penetration skirt is smeared with mastic.
The shingle is cut as close as possible to the ledge of the penetration, the gap is then filled with mastic, which is covered with a special UV-protective dressing.
starting strip
The installation of soft tiles begins with the laying of the starting strip. Usually it is a ridge-cornice tile or an ordinary one with cut petals. The first element is laid on one of the edges of the slope, going to the edge of the gable plank. The lower edge of the starting strip is laid on the drip, stepping back from its fold 1.5 cm.
Before installation, the protective film is removed from the back, the shingle is leveled and laid. Each section of bituminous tiles is fastened with four nails - at the corners of each fragment, stepping back from the edge or perforation line 2-3 cm.
If a cut from an ordinary tile is used as a starting strip, in some part of it there will be no adhesive composition. In these places, the substrate is smeared with bituminous mastic.
Installation of soft ordinary tiles
There is a flexible tile with an applied adhesive mass, protected by a film, and there is a composition that does not require a protective film, although it also fixes the elements well on the roof. When using the first type of material, the film is removed immediately before installation.
Before laying bituminous tiles on the roof, several packs are opened - 5-6 pieces. Laying is carried out from all packs at the same time, taking one shingle from each one in turn. Otherwise, there will be pronounced spots on the roof that differ in color.
The first shingle is laid so that its edge does not reach the edge of the starting strip by 1 cm. In addition to the adhesive composition, the tiles are also fixed with roofing nails. The number of fasteners depends on the angle of the slope:
When installing soft tiles, it is important to drive in nails correctly. Hats should be pressed against the shingle, but not break through its surface.
Valley design
With the help of a paint cord in the valley, an area is marked in which nails cannot be driven in - this is 30 cm from the middle of the valley. Then mark the boundaries of the gutter. They can be from 5 to 15 cm in both directions.
The upper corner, which is turned towards the valley, is cut
When laying ordinary shingles, nails are driven in as close as possible to the line beyond which nails cannot be hammered, and shingles are trimmed to the floor of the gutter laying line. To prevent water from flowing under the material, the upper corner of the tile is cut obliquely, cutting off about 4-5 cm. The loose edge of the tile is smeared with bituminous mastic and fixed with nails.
Decoration of the pediment
On the sides of the slope, the tiles are cut so that 1 cm remains to the edge (protrusion) of the end plank. The upper corner of the shingle is cut in the same way as in the valley - a piece of 4-5 cm obliquely. The edge of the tile is smeared with mastic. A strip of mastic - at least 10 cm. Then it is fixed with nails, like the rest of the elements.
If the flooring in the area of the ridge is made solid, a hole is cut along the ridge, which should not reach the end of the rib 30 cm.
It is fixed with long roofing nails. On a long skate, several elements can be used, they are joined end-to-end. The installed metal ridge is covered with ridge tiles. A protective film is removed from it, then the fragment is fixed with four nails (two on each side). The installation of soft tiles on the ridge goes towards the prevailing winds, one fragment overlaps the other by 3-5 cm.
The ridge tile is a ridge-eaves divided into three parts. A perforation is applied on it, a fragment comes off along it (first bend, press the fold, then tear off).
The same elements can be cut from an ordinary tile. It is divided into three parts, not paying attention to the drawing. At the resulting tiles, a corner is cut off - about 2-3 cm on each side. The middle of the fragment is heated with a building hair dryer on both sides, placed in the middle on a bar and, gently pressing, bend over.
Ribs and kinks
The ribs are covered with ridge tiles. A line is beaten off along the bend at the required distance with a masking cord. The edge of the tile is aligned along it. Laying of flexible tiles on the edge goes from bottom to top, each fragment is glued, then stepping back from the top edge of 2 cm, fixed with nails - two on each side. The next fragment comes to the laid 3-5 cm.
Until recently, only galvanized steel, tiles and slate were used as roofing material. Several people were involved in the installation work, who spent a lot of time and effort on the work. But today the range of materials has expanded and now, after the construction of the roof, one person can cope with roofing work, a lot of new things have appeared - for example, a soft roof.
In terms of its technical and operational characteristics, soft roofing is in many ways superior to other materials. Its advantages include:
- ease of installation (can be handled alone);
- strength;
- durability;
- flexibility;
- resistance to moisture and corrosion;
- tightness;
- attractive appearance.
Varieties of soft roofing
Often the following types of roofing are used as roofing:
Attention! If the top layer of the roof will not be removed, then when buying a soft roof, you should clarify whether it is compatible with the material from which the structure is made.
Preliminary work
Installation begins with preparation.
Stage 1. Preparing everything you need
As already noted, laying a soft roof can be done by one person. For work, he will need a completely standard list of materials:
Stage 2. Preparatory work
The base must be as strong as possible, its deflection is unacceptable. There are several materials that can be used for strengthening:
- plywood;
- OSB boards;
- grooved boards 10 cm wide.
It is characteristic that in winter small gaps (about 3 mm) should be left between the seams of the skin. If the structure is sheathed with boards, then 5 mm.
Attention! It is desirable to treat the rafter system to protect against decay and insects, as well as flame retardants - to increase the refractory properties.

Stage 3. Ventilation gap
It solves the problem of high humidity and reduces the amount of ice that forms in winter. Moreover, in summer, ventilation reduces the temperature inside the roof sandwich.
Ventilation consists of three main elements:
- ventilation outlet;
- valves for fresh air supply (installed from below);
- an air gap of 50 mm between the base and the waterproofing layer.
Attention! If the slope of the slope exceeds 25ᵒ, then the area of the ventilation hole should be 8 cm². If the slope is less than 25ᵒ, then 16 cm².
Stage 4. Intermediate layer
In this case, a gasket means a special one laid around the entire perimeter of the roof. Installation is made from the bottom up, starting from the eaves. An overlap of 10 cm is observed. The material is fixed with nails every 20 cm.
When the roof slope is less than 18ᵒ, the lining can be laid not over the entire area, but only in certain areas, such as:
- skate;
- overhangs of cornices;
- junction with a vertical wall;
- location of the chimney.
Attention! If the slope is less than 12ᵒ, then the use of a soft roof is not recommended.
Stage 5. Installation of strips
Step 1. To protect the material from atmospheric precipitation, cornice strips are installed on the overhangs, you can directly on top of the gasket material. Planks (another name - droppers) are located with an overlap of 2 cm and are fastened with roofing nails (zigzag, along the entire length of the plank).
Step 2 Gable strips are installed at the ends of the structure. This must be done with the same 2 cm overlap. Nails are hammered in 10 cm increments.
Step 3. The exit point is marked (if the house has a heating stove).
Step 4. Upon completion of the installation of the planks, the valley carpet is laid, which will significantly increase the moisture resistance. The color of the carpet should match the color of the roof, the edges are fixed with nails in 10 cm increments.
After that, you can start laying the roofing material.
Below is the technology for laying bituminous tiles, since this is the most common type of soft roof.
Stage 1. Cornice tiles
Cornice tiles are laid on the planks fixed on the overhangs. For fixing, galvanized nails are used - they are hammered in two rows 2.5 cm from the upper and lower edges of the material.
Instead of cornice tiles, you can use an ordinary one, which will save a little. For this, the tile is cut out - a shingle is taken and the petals are cut from it. In this case, the installation is carried out "end-to-end" at a distance of 2 cm from the cornice overhang.
Stage 2. Tiles
Attention! Do not forget about color deviations. Even if all the tiles are from the same batch, the tone in different packages may differ. For this reason, it is recommended to mix six to seven packs beforehand.
Step 1. Laying starts from the center of the roof overhang and is carried out in both directions.
Attention! The protective film is removed from the shingles immediately before installation, because without it the material cannot be stacked.
Nails are used for fastening. Usually four pieces are enough for shingles, but if the roof slope exceeds 45ᵒ, then six is better.
Step 2. The first row is laid in such a way that its edges recede from the edges of the cornice overhang by 1-1.5 cm. At the same time, the petals cover the joints between the cornice tiles.
Step 3. The second row is laid in the same way, but the petals should overlap the cutouts of the previous one.
Step 4. At the edges, the material is cut along the edge and glued. There should be a layer 10 cm wide.
The same is done in the end - the tiles are cut to obtain a 15-centimeter strip, after which the edges are smeared with glue by about 7-8 cm.
Attention! When trimming tiles, it is advisable to put a piece of plywood under it so as not to damage the underlying layer.
Stage 3. Ridge tiles
Step 1. First, the scaffolding is prepared. They will greatly simplify the work with the roof ridge, but at the end of the work, do not forget to glue the petals of the shingles at the attachment points.
Step 2. The tiles are overlapped (approximately 5 cm), each shingle is fixed with four nails.
Attention! Ridge tiles are laid only after the laying of the ordinary is completed.
Step 3. To obtain a ridge tile, the eaves are cut at the places of perforation. Further, each element is bent and laid in a short part along the roof ridge.
Stage 4. Passages and junctions in the roof
There are several ways to organize passages through the roof. So, if the diameter of the passage is small, then it is better to use special rubber seals. This applies to inputs for antennas and other communications, but the pipes are finished in a slightly different way - here it is necessary to take into account possible heating and, as a result, expansion, therefore the technology is used differently.
Step 1. First, a triangular-shaped rail is nailed along the perimeter of the junction of the pipe and the roof (in most cases - 5x5 cm).
Step 3. The pipe is glued with insulating material so that 25 cm of the slope and 35 cm of the pipe itself are closed.
On this, the installation work is almost completed, it remains only to fix the adjacent bar around the entire perimeter of the pipe. Next, an iron apron is fixed, and the seams are carefully sealed with silicone-based sealant.
Adjacency to vertical walls is carried out in the same way. The only difference can be considered that the triangular rail does not form a perimeter, but is fixed along the wall.

Roll roofing
Rolled material, which is also called euroroofing material, is laid mainly on flat roofs, although it can sometimes be found on pitched roofs with a slight slope.
The technology looks like this.
Step 1. After rolling out the roll, all the folds are leveled and the material is stretched.
Step 2. One side of the roofing material is heated with a special burner until a special indicator melts.
Step 3. After that, the side is glued to the base. When the material has cooled, the roll is rolled up again to the place of fixation.
Step 4. The roofing material is fused and gradually rolled out. In this case, you must adhere to certain rules.
- The roofing material is welded with an overlap of 5 cm. For this, a special indicative strip is applied along the entire length.
- Do not overheat the material, otherwise it will deteriorate, lose its ability to stick.
- A high-quality weld material must be homogeneous - without voids, dark spots, etc.
The joints with other surfaces are treated with bituminous mastic, which, after drying, will have the same properties as euroruberoid.

As a conclusion
The main points of installation, discussed above, will help to understand the essence of the issue even for a non-specialist. The main thing to remember is that compliance with the installation technology and strict adherence to all instructions will extend the operational life of the soft roof.
