Do-it-yourself soft roof installation technology. Covering the roof with a soft roof Installing soft tiles on steep roofs

A roof covered with bitumen shingles is aesthetically pleasing, durable, and easy to use. Its great advantage is the possibility of self-installation. There is nothing complicated about how to cover a roof with a soft roof with your own hands, since the weight of the material is small, installation is carried out on an adhesive base with additional fixation with nails.

Currently, this type of coverage has become popular among property owners. A do-it-yourself soft roof made of bitumen shingles has a very attractive appearance; it is characterized by increased moisture resistance and a long service life.

On the back side of this roofing material there is a self-adhesive layer. Thanks to its presence, it is possible to install a soft tile roof with your own hands in the absence of the appropriate skills.

Features of flexible roofing material

Soft tiles are tiles with a curved edge. It is made of fiberglass, which is impregnated with petroleum bitumen modified by polymers. When arranging the roof, the material is laid overlapping so that an imitation of a shingle covering made of wooden blocks is created.

The fiberglass contained in such tiles can be ordinary or reinforced polyester. During the manufacturing process, the outer side of the material is covered with a special coating made from basalt or stone chips, due to which the roof has a rough surface and a certain color.

The advantages of bituminous shingles include:

1. Aesthetic appearance. Since the material is produced in a variety of colors and shapes, it is possible to give the house a harmonious image.
2. Long service life. A soft roof can be used for at least 70 years and during this period the costs of its installation will be fully recouped.
3. Flexibility. Elastic products make it possible to install soft roofs of complex shapes, with many decorative elements.
4. Resistance to adverse weather conditions. A soft roof can withstand the effects of ultraviolet radiation, precipitation and other environmental factors while maintaining performance characteristics.

The technology for laying tiles is simple and therefore even a home craftsman can easily install a soft roof roof with his own hands for a country cottage, country house, gazebo and other buildings.

Installation of soft roofing

Before you make a soft roof with your own hands, you need to make sure there is a solid foundation. According to the installation technology of this material, the work can be performed under specific weather conditions.

1. When installing at air temperatures below plus 5 degrees, the self-adhesive layer on the back of the tile cannot melt on its own. To do this forcibly, you will need to use a hair dryer or a gas torch. But the melting of bitumen will affect the installation time of the soft roof.
2. When this material is laid at a temperature exceeding 25 degrees, the self-adhesive layer begins to melt strongly and flow down the slope. At high temperatures, deformation of the roofing occurs.
3. If installation work is carried out in conditions of high humidity, this will negatively affect the durability of the sheathing, rafters and the tiles themselves due to rotting.

The instructions for installing a soft roof with your own hands, compiled by the manufacturers, prescribe that this should be done exclusively at an air temperature of 5 to 15 degrees, when the weather is dry.

Do-it-yourself roof sheathing

First of all, you need to make a reliable crate. According to the technology for installing soft coverings, there must be a solid base that will give the soft covering of the roof the required strength and rigidity.

The presence of the lathing guarantees an even distribution of the load on the rafters, so it is made of three layers:

1. Counter-lattice. It is built from wooden blocks 3–4 centimeters thick and mounted on top of the waterproofing along the rafter frame legs. This layer serves to create an air gap between the covering and the rafters.
2. Sparse sheathing. This part of the base for soft material is made from edged boards measuring 20x150 millimeters. The elements are fixed perpendicular to the bars of the counter-lattice with an interval of 30–50 centimeters.
3. Continuous sheathing. It is built from moisture-resistant plywood, edged boards or OSB boards. They are laid continuously with a small gap of 1–3 millimeters, which serves to compensate for the thermal expansion of the sheathing.

Before laying a soft roof, the wood elements must be made smooth so that they do not damage the tiles. It is better to use softwood material with 20% humidity. To prevent the wood from starting to rot, the products must be treated with antiseptic compounds. To eliminate the risk of fire, the lathing is impregnated with fire-resistant preparations.

Laying underlay carpet

There is a certain procedure for how to properly lay a soft roof. It is mounted on a continuous sheathing. Before laying a soft roof, a bitumen lining carpet that is resistant to mechanical stress is placed on top of the base. It protects the roof structure from leaks and damage.

According to the technology for installing the underlay carpet:

• if the roof slope is less than 15-18 degrees, it is laid out over the entire area of ​​the slopes with a 15-20 cm overlap, so that if the snow melts, moisture does not linger;
• if the angle of inclination is more than 20 degrees, the lining is laid exclusively in places where precipitation can accumulate - such additional waterproofing is used to protect the joints of soft roofing on slopes with a vertical surface, valleys and ridge;
• Roofing felt cannot be used for lining, as it is fragile and will not last long.

According to professionals, as a backing layer you need to use products recommended by manufacturers, since it is guaranteed to be compatible with the purchased tiles.

How to cover a roof with soft tiles

Installation should be performed when it is calm and dry outside. When laying it on a previously used rafter frame, first check the condition of the wooden elements and replace those that are deformed or rotted.

Installation work is performed in a certain order:

1. Using a pre-prepared drawing of a soft roof, chalk marks the surface of the slope with horizontal stripes, marking the location of the rows of tiles.
2. Laying begins from the bottom of the slope, fixing the roofing with special nails. If the fastening is carried out using a self-adhesive layer, you need to remove the protective film from the tile and press the product to the base. The nails are driven in no closer than 2.5 centimeters from the edge, flush with the surface of the tile.
3. The next row begins on the left side. 143 millimeters are cut off from the tile on the left, shifting the pattern diagonally.
4. To begin laying the third row, a fragment of 286 millimeters in length is removed from the product from the left edge so that the pattern of the material moves in the diagonal direction.
5. After completion of the work, the ridge and valley junctions having a vertical surface are decorated with a ridge element.

To ensure the proper functioning of a roof made of bitumen shingles and to prevent the “greenhouse effect”, a ventilation system should be installed and thereby prevent rotting of the truss structure.

Soft roofing materials are becoming more and more popular. What causes increased demand, since the price of such a roof is not the lowest? Craftsmen choose this type of coating because it is practical to use, durable and very easy to install. Novice craftsmen can easily cope with the installation of such a roof with their own hands. What types of soft tiles are there, what are their advantages and how to master the technology of laying soft roofs, read right now!

A little about the features of soft materials

If anyone thinks that soft roofing is a new material on the construction market, then we hasten to remind you that the “progenitor” of flexible roofing was ordinary roofing felt. Let's look at three main types of flexible roofing:

I. Bitumen roll materials

Rolls of bitumen coatings are an improved roofing material. They are attached by fusing to the prepared roof surface. A newer type of roll roofing is polymer membranes. These coverings are glued to the roof completely or partially (at the joints).

It is advantageous to use rolled materials for large industrial buildings, as they are characterized by quick installation and relatively low cost. The roof slope for rolls is 3-9 degrees.

II. Bituminous shingles

Unlike bitumen rolls, tiles have more advanced characteristics and are produced in shingles (strips, tiles). The free side of the tiles is shaped like a tile to create the visual effect of a ceramic coating.

The main advantage of shingles is that they can be laid on surfaces with any slope, which is especially important for the roofing of private houses. The slabs are glued starting from the bottom, with the upper edges. Additionally, the shingles are secured with self-tapping screws. When the sun heats the surface of the asphalt shingles, the sheets fuse to form a continuous, sealed surface.

III. Roofing mastic

This is a liquid type of roofing. The material is either supplied immediately in liquid form or requires heating to certain temperatures. The mastics are poured onto the reinforcing mesh and allowed to harden, forming a monolithic surface. This type of roofing has excellent characteristics, but is only suitable for flat roofs, so we won’t talk about it in detail today.

Valuable properties and disadvantages of soft materials

We list the main advantages of a soft roof:

• Flexibility and elasticity of roofing material. This property allows you to cover complex roofs with minimal coating consumption, practically without waste and additional seams;
• Easy to install. Bituminous materials are very easy to install. You can lift lightweight tiles or rolls onto the roof and spread them yourself. The installation technology can be mastered by any owner who has such a desire;
• Minimal roof weight. The material is light in weight. This reduces the load on the rafter system;
• No noise effects, such as with corrugated sheets. Rain, hail and wind are practically inaudible when in contact with a soft roof;
• Availability and ease of roof repair if necessary. Asphalt shingles are easy to walk on because they do not slip. If any section of the coating has become unusable, you can only replace it without affecting large areas;
• And, one cannot fail to note the practicality and durability of the coating. Bituminous materials can withstand temperature changes and mechanical stress, and do not lose quality and decorative properties for many years.

Some of the difficulties that arise when choosing a soft roof include increased requirements for the sheathing (it must be solid and perfectly flat) and possible additional costs for the material (there are expensive and cheaper coatings). Another drawback is the flammability of bitumen shingles. However, modern technologies can reduce this risk factor.

We master the technology of installing soft roofs: instructions and diagrams

The installation of a soft roof consists of laying bitumen plates or rolls on a prepared base. We will describe the stages and features of installation of materials in as much detail as possible.

What is a rafter system for soft tiles?

The design of the rafter system for flexible covering is practically no different from the base for hard materials. Mauerlat, rafter legs, purlins, racks and other elements are installed according to standard rules. The main nuance is the sheathing, which needs to be given special attention. The soft roof must be laid on a flat, continuous surface, so moisture-resistant plywood or other similar materials must be laid on the counter-lattice:

Let's consider the optimal roofing pie for a flexible roof:

1. Rafter legs of standard sizes and fastenings;
2. Insulation for the roof (if you are making a warm roof);
3. Roofing vapor barrier film;
4. Counter-lattice boards laid perpendicular to the rafters;
5. Lathing with OSB or plywood boards;
6. Special lining material for tiles - lining carpet;
7. Soft roofing;
8. Gutters, ridges and other finishing details.

The roof is insulated from the inside with any materials and finished with finishing cladding. Let's consider all the stages in order.

I. Preparation of materials and tools

At this stage, it is necessary to calculate the rafter system, purchase everything necessary for the roofing cake and prepare the tools.

You will need: a pencil, a tape measure, a folding meter, a knife for soft tiles with a straight and hook-shaped blade, a hammer, a hammer, a construction gun, a mastic spatula, a heat gun, metal scissors, a screwdriver.

II. Laying vapor barrier

Vapor barrier is necessary to prevent warm air vapor from the room from entering the roofing materials. For a warm roof, a vapor barrier is installed from the inside of the attic on the rafters. The rolls are rolled out parallel to the cornice, starting from the ridge. The overlap is 10-15 cm on the inside; the overlap on the walls is also very important. Fix the film using a construction stapler. The joints are covered with adhesive tape on a metal base:

An aerator is installed for ventilation:

Rules for installing junctions:

III. Installation of insulation

Installing insulation helps establish optimal thermal conditions inside the building and prevent heat loss from the living space. Before laying the insulation, it is necessary to form a rough filing from the inside - wooden planks on top of the vapor barrier membrane. The choice of the type of material and the thickness of the insulating layer depend on the climate and characteristics of the building. For residential buildings in central Russia, for example, experts often use mineral wool in a layer of 20 cm.

Several layers of material are laid into the body of the rafters with staggered seams for a better insulating effect. The sheets are joined closely so that there are no gaps. The thickness of the layer at this stage should be 15 cm. Next, we mount a 50x50 mm beam perpendicular to the rafters (step 50-60 cm). A final layer of thermal insulation - 5 cm - is laid between the beams. This technology eliminates cold bridges.

IV. Installation of roofing vapor barrier

The vapor diffusion membrane protects the insulation from moisture and dust without preventing the release of vapors into the external atmosphere. The vapor barrier is laid along the eaves, directly on the insulation layer with an overlap of 10-15 cm. It is necessary to ensure that the membrane extends beyond the insulation layer on the eaves by 10-15 cm. The membrane is fixed with a construction stapler, the overlaps are taped with a special tape.

In order for the roof to last as long as possible, ventilation of the under-roof space is simply necessary. It helps remove steam coming from the room and equalizes the temperature over the entire surface of the roof. To ventilate the attic, it is necessary to create an air gap of at least 5 cm between the insulation and the base of the roof. An additional layer of counter beam with a cross section of 50 mm is installed parallel to the rafters. We make gaps of 5-10 cm between the bars. This will ensure the necessary air circulation.

V. Base design

Under the flexible tiles there is a continuous base made of moisture-resistant slabs. When laying, we install the slabs staggered with a gap of 3-4 mm. The gap is necessary to compensate for the expansion of the slabs under the influence of moisture and air.

We install aprons on the base with a distance of 2-3 cm beyond the edge of the slabs. We fix the planks in increments of 25-30 cm using self-tapping screws. We treat the overlaps with sealant. Next, you can install the roof drainage system according to the standard scheme, which we described in previous materials.

VI. Waterproofing

Base slabs require additional waterproofing. To do this, you can use rolled lining materials. We start installing the rolls from the cornice. We lay the insulation parallel to the base apron with an overlap of 15-20 cm. All joints should be sealed with bitumen mastic:

If the roof slope angle is more than 30 degrees, then continuous waterproofing may not be necessary. It is enough to seal the seams of the base and lay the rolls (about 50 cm wide) in valleys, eaves overhangs, window areas, ventilation holes, etc.

VII. Laying tiles

On the roof it is necessary to carry out markings according to the instructions that are given for a specific roofing material. About methods of laying soft tiles in valleys:

• The "Pigtail" method. A necessary condition for laying tiles in this way is the same slope of adjacent slopes. The material spreads onto the slopes and covers the valley with entry onto the adjacent slope. The same is then done on the adjacent slope;
• Trimming method. Initially, the tiles are laid on a slope with a smaller slope and length. A line is drawn on the adjacent slope parallel to the axis of the valley. Each row of tiles is inserted through the valley onto the adjacent slope and cut along the line. The valley area should not be pierced with nails (30 cm from the corner). On the next slope, we begin laying in the same way, marking a parallel line on the opposite side by 5-10 cm.

Based on the markings, we begin laying soft tiles from the eaves. We cut the first strip (shingle) along the line and glue it at a distance of 1 cm from the edge of the eaves overhang. We fasten the tiles with ribbed roofing nails, the length of which is 25-30 mm. Each nail must penetrate both the top edge of the new shingle and the existing material underneath. On steep slopes, the upper edges of the slabs are secured with two additional nails.

We cut the ridge elements from tiles. They are laid in the preferred direction of the wind with an overlap. Each element is fixed on both sides with nails and glued with bitumen mastic. For better bending, it is recommended to heat the inner surface of each element with a hair dryer.

Installation of a ventilation ridge

To install a ventilation ridge, we do not bring the base of the roof to its line, leaving 10 cm. Then we install 50x50 mm bars along the ridge in increments of 30 cm. We install another row of the same bars behind the previous ones, according to the markings. Next, we install the apron and attach the insect net. We install waterproof plywood on the bars, which we cover with an apron and tiles. Now you can install.

So, installing soft tiles yourself is quite feasible, and it is much simpler than installing hard materials. Choose high-quality materials, get ready for fruitful work and go for it! We wish you good luck.

Private construction and the use of soft roofing is a fairly relevant topic. This material has a lot of advantages. Among them are low weight, absolute tightness, visual appeal, the possibility of using a wide variety of roof shapes, long useful life and low cost of soft roofing. Moreover, the rain does not drum on such a roof, but rustles quietly. In addition to high performance and technical characteristics, the material allows you to install a soft roof yourself, without involving specialists.

The concept of a soft roof

Soft roofing is a modern material, the base of which is fiberglass sheets impregnated on both sides with rubber bitumen. Rubber bitumen is highly airtight and moisture resistant, which is why soft roofing has become so widespread in the construction of buildings. Also, soft roofing contains a special coating that increases wear resistance and prevents the roll covering from sticking together.

Soft roofing is considered an ideal covering for roofs with a slope of at least 11 degrees. Therefore, when choosing a material for such strict requirements, be careful. Soft roofing is often called bitumen shingles, which are used as the top layer of the roofing cake and differ from other materials in its structure, which resembles rolled materials.

Styling tools

Flexible roofing can be laid by 1 person. The only requirement for the roof surface, which we have already mentioned, is a slope of no more than 11º. But the maximum slope angle is not limited. Laying a soft roof with your own hands requires the following materials and tools: a hammer, a knife, mastic, sealant, a mastic trowel, roofing nails, eaves and end strips, a waterproofing carpet, a ridge-eaves strip and work gloves.

Ventilation device

The ventilation system is able to provide air circulation, which is necessary to prevent condensation from occurring on the lower part of the base. Neglecting this stage when laying soft roofing on the roof will cause the rafter system to begin to rot, and ice and icicles will form in winter.

The constituent elements of the roof ventilation system are ventilation ducts and outlets, gaps between the waterproofing and the base (minimum 5 millimeters). Natural ventilation can be provided by ventilation holes that are distributed evenly under the eaves.

Lining layer

Cornice strips are made of metal and attached to the overhangs of the cornices on a lining. They are required to protect the edges of the sheathing. Gable strips are also made of metal; they are attached to the ends of the roof to protect the edges of the sheathing. The valley carpet provides additional protection of the roof from precipitation. Choose it according to the color of the flexible tiles.

In places where leaks are most likely, you need to create a lining layer: on valleys, roof ends and eaves. A special feature of the installation is compliance with the direction (bottom to top) and overlap: in the longitudinal direction - 150 millimeters, in the transverse direction - 100 millimeters. It is customary to coat the overlap areas with bitumen mastic.

It is customary to reinforce the valleys and ridges by 500 and 250 millimeters, respectively. In this case, the valleys must be equipped with a lining layer on both sides, and along the ends and eaves overhangs it should be laid to a width of at least 400 millimeters.

The lining is nailed to the base with galvanized roofing nails every 200 millimeters. The underlay not only protects the roof from moisture, but also from destruction if the installation of the soft roof is suspended.

Preparatory work

The base to which you will attach the soft roof must be solid. This is precisely why the process of installing a roof made of soft tiles differs from roofs for which other materials are used. For example, metal tiles must be laid on a sheathing in which a gap is allowed between the beams, which is explained by the high rigidity of the metal tiles. A soft roof does not possess these qualities and therefore requires preliminary installation of a solid foundation.

For arranging the base, you can use oriented strand board, moisture-resistant plywood with a thickness of 9 millimeters or more, as well as tongue and groove or edged boards. If you have chosen a board as the base, it is recommended to first keep it in a stack until an equilibrium moisture level is reached.

Buy material in winter and use in summer. The width of the boards is no more than 100 millimeters. It is desirable that the material has the same thickness and is sawed on a band saw. The maximum moisture content of wood is 20%.

The video about the technology of laying soft roofs shows that such materials need to be laid with the seams shifted - staggered, leaving a gap of 1 centimeter between them. The surface must be dry, clean and smooth. The quality of installation and service life of the soft roof will depend on these conditions.

The roofing pie must necessarily have the following layers: a waterproofing layer laid on the rafters; mineral wool insulation if you are planning to install an attic; waterproofing roofing carpet laid overlapping on the base from the outside.

Subtleties of installing a soft roof

To cover a roof with a soft roof with your own hands, in addition to having free time, you also need good weather. It is customary to carry out work in warm, dry weather, and the air temperature should not fall below plus 5 Celsius. If, due to necessity, it is necessary to lay a soft roof in winter at an inopportune time, the tiles must be kept in a building at room temperature before starting work. You can also use a hot air burner.

The choice of this temperature regime is explained by the characteristics of the shingle - a sheet consisting of 3-4 “tiles”. It can be attached to the surface with nails or using a self-adhesive layer located on the inside. The tightness of the tiles is ensured by the heat of the sun; under its influence, the sheets are soldered to the base and to each other. This does not happen at sub-zero temperatures, and high-quality insulation does not work.

Soft tiles should be used simultaneously from 5-6 packages and selected one element at a time to avoid sharp differences in shades in case it is necessary to repair the soft roof with elements from another package. It is this property that constitutes another advantage of this material: a slight difference in shades facilitates the process of replacing tiles and decorates its matte surface.

Choice of mastic

To lay the top layer of a soft roof, you should use a bitumen-polymer material, which allows you to create a continuous elastic coating that can withstand temperature and mechanical deformations of the base. According to the technology of laying soft roofing, it is recommended to use cold and hot mastics to attach rolled material to the roof.

Cold mastics are traditionally used for the internal layers of the roof, and the hot substance is used as an external coating. Cold mastics include roofing felt and bitumen, and hot mastics include tar and roofing felt. The mastic used must contain bitumen and a pulverized mixture or fiber filler. Among the dusty materials are lime, gypsum and ash.

Production of bitumen mastic

You can buy bitumen mastic, but you can also make it yourself. To do this, take bitumen, which is close to 80% of mastic, and filler. By taking 2 portions of bitumen and diesel fuel per 1 portion of filler, you will get a cold mixture. The bitumen needs to be heated to 180 degrees while diesel fuel and filler are being prepared elsewhere. Both boilers can be mixed only after the water has evaporated in the bitumen.

To make hot mastic you need to use a boiler. The bitumen in it should be heated to 200 degrees, and filler should be added slowly. It is important that during the procedure the temperature does not drop below 160 degrees.

To check the quality of the mastic, you need to lay it at an angle of 45 degrees, after preheating the mastic to 60 degrees. The video about laying a soft roof shows: if the coating drains, then its quality is poor. If it does not drain, then you should let it dry. When drying, cracks will not appear in high-quality material.

Laying a soft roof

Before directly laying the roof, run a solution of bitumen and diesel fuel over the wood surface. Then slowly coat with mastic, then lay down glassine and roofing felt. It is customary to start installation from the middle part of the cornice and move towards the ends to the right and left. On the underside of soft tiles, before applying, you need to remove the film that protects the glue.

If you use cold mastic, then you need to wait 12 hours after applying a layer, only then can you apply a new layer. When covering with hot mastic, you can apply layers one after another. Each roofing element must be nailed in the amount of 4-6 pieces.

When laying rolls according to the instructions for laying soft roofing, make a 7-10 cm overlap. In all cases, it is recommended to follow the overlap rule: place each top row so that the fastening joints of the previous one are covered. The next new layer is shifted depending on their number (with 2 layers - by half, and with 3 - by a third).

Along the edges of the roof, trim off the excess and glue with mastic. Thanks to the properties of modern soft roofing materials, the useful life of the roof covering is about 30 years. But this does not mean that you can forget about preventive measures.

Installation near ventilation pipes

Proper insulation of joints and careful fastening of material require space around antennas and pipes. Installation of a soft roof here is easy provided that passage elements are used. Without such components, the tightness of the coating is compromised. Even before laying the bitumen shingles, you need to outline the places where you will install ventilation and pipes.

Then you need to cut holes around which the edges of the lining carpet will be glued with mastic. Spread the top surface of the carpet along the contours of the elements that need to be glued and nailed. Place the tiles on top of the mastic.

It is recommended to treat the joints between the upper part of the passage element and the bitumen shingles with sealant. Having completed the work to the ridge line, you need to use special ridge elements of flexible tiles, which are bent over it, glued to mastic and nailed.

Soft roof repair

The frequency of repair work that needs to be carried out on the roof of a house depends directly on the base on which you installed the tiles and on the cost of laying a soft roof. Wooden lumber, cement and concrete screed - they all react differently to soft roofing, which causes some damage.

Cleaning the damaged area

Immediately before starting repairs, determine whether such work is needed at all and to what extent. To do this, assess the extent of the damage present. If holes have formed in the rolled covering, it is recommended to fill them with mastic, observing the sequence of materials used for this.

Roll roofing repairs should be carried out exclusively in a clean area. And this is very problematic, because the roofing material contains a special coating. For this reason, it is necessary to thoroughly clean the area where repair work will be carried out.

Crumbs can be removed by using process oil. Anthracene oil is best suited for cleaning roofing felt, while solar oil is used for roofing felt. Clean with a regular rag or brush. With this treatment, you can remove the coating and soften the surface for further repairs.

Repair work

After preparing the damaged area, you can proceed to the main work. For small defects, you can use regular mastic with a patch. But this solution is not suitable if all roofing layers are broken.

If several layers of the roof are damaged at the same time, it is recommended to clean the area from the old layer of mastic and dirt, and then dry it. After this, you need to prepare a mastic mixture with the addition of sawdust or sand. This mixture should be used to fill all existing damage so as to even out the edges. The mastic should extend at least 10 centimeters on all sides of the patch.

Using hard brushes and brushes, mastic can be applied to the most difficult to reach places. If you are working on a small area, then it is advisable to use a simple spatula, which allows you to apply thick mastic and sawdust mixture. If a “water bubble” occurs in the roof, repairs must be carried out in the same way as in a situation with a regular hole. The main thing is to determine in time the source where the water comes from.

If cracks appear in the roofing material, it should be cut to the bottom layer. Then clean off excess mastic and debris, after which the area is dried and filled with new mastic. You can do without a cut if the cracks are small. They should be covered with a patch and mastic. If small cracks appear throughout the entire area of ​​the soft roof, it must be prepared and covered with heated mastic.

Restoration of sprinkles

After repairing the soft roof, it is necessary to replace the removed layer of topping in place to avoid unnecessary heating of the material and melting of the mastic. To do this, smooth the surface and cover the roof with sand. Excess coating that does not stick to the roof will be removed on its own over time. However, if you want, you can remove it yourself.

Now you have learned what advantages a soft roof has - tightness, long service life and a reasonable price for laying a soft roof. Follow our instructions carefully to install flexible tiles correctly. Use the recommendations regarding the choice of mastic and its preparation. And if minor problems arise during the operation of the roof, re-read the information about repairing soft roofs.

In this article you will find instructions with step-by-step photos and video tips on how to make a soft roof with your own hands using a roof as an example.

Preparatory stage

Installation of a soft roof begins with the installation of a new or repair of an existing sheathing:

1. After installing the rafter system, the inside of the roof is covered with a vapor barrier film, which is overlapped and fixed with bars.

2. Insulation boards are located between the rafters. Their thickness, density and number of layers are determined by the architectural features of the roof and the climate of the region.

3. From the outside, the insulation is covered with a superdiffusion membrane. Counter-lattice bars are installed on top of this layer - they are attached along the rafters, create the necessary ventilation gap and form an additional frame for OSB or plywood.

4. The final stage is installation of the sheathing. Its type depends on the roof slope. At 9-20 degrees it is necessary to install a solid base under a soft roof made of moisture-resistant FSF plywood, OSB-3, DSP, boards. At 20 degrees and above, a sparse base made of a board with a thickness of at least 25 cm or a bar with a thickness of at least 50 cm is allowed. The two outer elements of the sheathing are mounted with a reduced gap of 30 cm, the rest - in increments of 32 cm.

5. In the case of a continuous sheathing, another layer of roofing cake appears - roll bitumen waterproofing is laid over the entire surface.

Important! This instruction provides the maximum permissible sheathing spacing. If possible, it is better to do more frequent or continuous sheathing.

Do-it-yourself soft roof installation

Before starting installation, be sure to check whether the roof slopes are level. If there are deviations, it is necessary to draw a strictly vertical line - you will be guided by it when centering the sheets.

When carrying out work, do not stretch the sheets by more than 10 mm and carefully follow the instructions with step-by-step photos.

Stage 1

Installation should begin on the side of the roof opposite the prevailing winds. Mark the overhang of the first row with a stretched rope. The optimal length is 3.5-5 cm. Secure the first strip by driving nails into the upper part of the wave strictly at an angle of 90 degrees.

Follow a specific hammering order.

Use special filler to protect eaves clearances from birds, snow drifts and debris. If necessary, the holes can be easily pressed with a handy tool of a suitable diameter.

Stage 2

Lay the second row, starting with half the sheet. There should be 3, not 4 overlaps at the corner joint - otherwise the roof may be deformed. Drive in nails, fixing both sheets at the same time. Install the following panels in the sequence shown in the figure. Make sure the locks match. To mark the sheets, you can use an ordinary colored pencil.

Important! Installation of Onduvilla is possible at temperatures from −5 to +30 degrees. In the cold season, the speed of work depends on the condition of the repair trains. With strong cooling, the adhesive properties of mounting tapes are lost, and sealants become more viscous. Therefore, consumables should be stored in a heated room, and during installation - kept in clothing pockets.

Features of installation of roofing elements

Installation of tongs

Fasten the end beam measuring 40*40 mm to the bottom of the ramp sheathing. Install the gable elements, placing them along the edge of the roof from the eaves to the ridge. The overlap should be 8 cm. Transverse lines are a good guide. Options for fastening components are clearly presented in the photo.

Ridge installation

Design the ridge elements. To do this, install covering aprons on both slopes with an overlap of 4 cm. Fasten the skates on top of them, taking into account the angle of the roof. If you use Ondulin roofing elements, the gaps must be closed with Onduvilla filler. The ribs of a multi-slope roof are designed in the same way - in this case, the joints of the slopes are additionally sealed using breathable tape.

Ventilated Onduville skates are also used to protect the slope joints. To begin, lay a breathable insulating gasket along the ribs, then cover it with a roofing element with an 8 cm overlap. Install special end caps at the ends of the ribs.

Installation of valleys

To lay the valleys, additional sheathing is required. Install 50mm thick timbers at the inner corners of the roof. The distance between their center and the rafters should be no more than 21 cm. Along the line of the slopes, install a continuous boardwalk with a width of at least 70 cm.

Install underlay waterproofing to protect against leaks. Here you can use Ondutis superdiffusion membranes. Make sure that the overlap of the panels is at least 30 cm.

Secure the valley to the resulting base. Installation of roofing elements is carried out in the direction from the eaves. The starting gutter is installed with a offset of 5-7 cm, which allows you to set the valley level with the cornice line. Subsequent parts are laid with an overlap of 15 cm and fixed in all corners using nails with wide heads.

Registration of junctions

To carry out the work, you will need an Onduvilla covering apron and a specialized tape with a metal coating “Onduflesh-Super”. To begin, lay the apron around the chimney/along the wall and nail it to each wave of the soft roof.

Cover the joint between the flashing and the wall/pipe with a strip of tape of the appropriate size. Make sure that the sealing material extends onto the vertical surface by at least 10-15 cm.

To fix the top edge of the tape, use metal profiles or wooden strips.

After finishing the work, cover the bottom of the tape with an additional sheet of Onduville soft roofing.

Ventilation outlets

Use additional elements to ensure complete sealing of junctions and avoid future leaks. Onduville ventilation pipes perfectly match the “native” soft roof, and deflector caps reliably protect the ducts from debris and precipitation. Installation is carried out as follows:

• Cut a hole of the appropriate size opposite 3 or 4 Onduvilla leaves. To do this, draw a line coinciding with the axis of the wave and measure along it 13.5 cm from the top edge of the sheet. Place the leg of the compass at the end of the line and draw a circle with a diameter of 12 cm. Carefully cut it out with a jigsaw.
• Install the ventilation pipe. Make sure that the profile of its base coincides with the waves of the soft roof.
• Lay Onduvilla sheets over the base and secure the vent pipe using proprietary nails.

Important nuances

Before installation, Onduvilla must be stored in a horizontal position. It is advisable to keep the original packaging. If it has been damaged, it is necessary to protect the opened pallets from moisture and contamination. Soft roofing cannot be stored near heating devices; the minimum distance is 1 meter.
