Flexible shingles are one of the most popular types of roofing . It is widely used in low-rise and cottage construction.
This practical and soft material has many names: flexible, bituminous and soft tiles, shinglas, roof tiles, shingles, etc.
Flexible tiles are produced in the form of separate sheets with cutouts of various shapes along the edge. It can be triangular, oval, hexagonal, wavy and so on.
A wide range of colors of this type of roofing is also offered.
The basis of flexible shingles is often a glass fiber impregnated with modified bitumen. Coarse-grained dressing applied to its surface endows the material with reliability and strength, increasing its service life. This roofing material can be used for finishing roofs of any shape. By combining different shades and patterns, you can create interesting designs.
The growth of popularity of soft tiles is greatly facilitated by its economical consumption and easy installation. In addition, it is virtually noiseless, which greatly increases its demand.
An oil refined product called bitumen is used to produce most types of shingles. Special SBS modifiers are added to it, which give it increased resistance to temperature extremes, strength and elasticity.
This modified bitumen mixture with polymers is applied on both sides to the reinforcing base.
The result is a flexible, deformation-resistant and durable roof covering.
Colored mineral chips are applied to the top layer: ceramic, shale or basalt. It helps to protect the coating from ultraviolet radiation, and also significantly improves its appearance. Sometimes, to give visible relief, a shadow strip is applied to the surface of the tile, for which granulate is used.
A self-adhesive strip is attached to the underside, which helps to hold the tile rows together and ensure the finished coating is solid.
The new material is protected by a special thin film to prevent the material from sticking together during transportation and storage. Before starting installation work, it is removed.
The durability and reliability of the roof largely depends on the quality of installation work.
Before starting working with tiles , it is important to do certain preparatory measures.
It is necessary to equip :
Since the main load from the entire roofing system falls on the rafter system, it must be particularly strong.
With special compounds, the wood elements protect from moisture, the ends of the rafters themselves are firmly fixed.
The rafter system is calculated taking into account the climate in the region and other operating conditions: wind, snow load, volume and weight of the roofing material.
A reliable vapor barrier must be provided before laying the tiles. For this, a special overlapping film is used.
Fasten it with double-sided tape.
The next stage of the preparatory measures before laying soft tiles - thermal insulation device . For this, you can use different materials, many of which are available on the market today. Mineral slabs are perhaps the most popular of these.
After installation of insulation , a protective diffusion membrane is mounted, which is an obstacle to wind and moisture.
It is attached with a bar 50-75 mm high, nailed in parallel to the rafters.
This creates the space under the roof covering for good ventilation. A crate is placed on top of the timber. It is made from edged or unedged boards with a thickness of one and a half centimeters.
All wooden elements are impregnated with special compounds that protect them from fire and moisture.
This roofing material needs a solid, even and rigid underlay. As such a base for it, thick plywood, resistant to moisture, is usually used, oriented strand boards. Even a dried tongue-and-groove board will do this, but the first options are better for this.
Plywood or OSB can change in volume due to moisture and temperature, so it is recommended to leave a 5mm gap when installing. Fix this base with nails or screws.
Then a backing carpet is placed on it under the shingles. It is a roll material, the main purpose of which is to protect the roof from possible leaks. It is especially needed in those places where the possibility of leakage is higher - eaves and valleys.
A backing carpet is unrolled over the surface with a certain overlap. The overlap is 10 cm in the transverse direction and 15 cm in the longitudinal direction.
The underlay is fixed to the flooring with galvanized nails, with a pitch of between about 20 cm. The overlap area is covered with a special bitumen mastic to increase reliability.
The next stage of arranging a tiled roof is the use of pediment strips. They are nailed to the wood flooring with the same galvanized nails, every 20 cm in a checkerboard pattern. At the joints, the overlap of the pediment strips is on average about 15 cm.
Soft tiles are usually laid from eaves.At this stage, it is important to correctly determine the right material. Most often, special tiles for cornices and skates are placed on the lining carpet. You can use a simple shingle for this. True, the patterned petals are first cut off from it.
From the bottom, the tiles are attached with special galvanized nails with a wide head. The very first row is best laid from the middle.
When laying subsequent ones, it is advisable to shift each canvas so that the lower edges of the petals to be placed are on the same level with the upper cutouts of the previous rows.
To ensure even laying, use a taut cord to mark the lines. There you can eliminate unnecessary offsets.
When fixing soft tiles, it is important to ensure that the nails being driven into the deck surface are strictly at right angles. The head of each nail is parallel to the shingle. For the installation of a roof made of soft tiles, rather warm weather is highly desirable.
It is better if the ambient temperature does not drop below 20 degrees.
But with too much heat, the tiles become too soft and may deform.
Therefore, if it is too hot outside, you need to move as carefully as possible over the newly laid roofing. In order not to spoil the tiles, special protective platforms are made. If the sun is shining strongly, it is better to carry out construction activities on the shadow side of the roof.
hands, you should pay attention to some important points.
It is best not to use one package of tiles one after the other, but to mix models from different packages at once. The fact is that individual parties may have very slightly different shades. Stirring up cancels out these differences, and you get a more even tone, with even transitions.
If, of course, they are available on the roof. These areas are most likely to suffer from possible leaks. A special coating has been developed for it, which is called "valley", and it is placed on the lining carpet.
However, when calculating the roof area and the required amount of material, it is better to take into account a small margin. For a simple structure, it can be 5 percent, and with a complex roof configuration (towers, cones, etc.) 12-15 percent.
A special grade of material is used for this - ridge-cornice tiles.Before installing it, you need to install a ridge aerator, which provides free air circulation to the under-roof space. It is attached to the base with galvanized self-tapping screws, while a 5-8 cm wide gap is prudently left under it.
This quality roofing the material is produced by one of the largest in Russia, the Ryazan plant Technonikol. The basis of the material is fiberglass impregnated with special bitumen.
The sheet is also covered with modified bitumen on both sides. The top layer is represented by basalt granulate, which can have various shades.
It is an excellent protection against aggressive and negative influences, in addition, it provides a chic appearance.
Self-adhesive mastic based on bitumen and polymers represents the lower layer of this material, which, in addition to everything, has a protective silicone film. It's easy to get rid of it.
Judging by the reviews, shingles of this brand have gained quite a lot of popularity among consumers. Users appreciate this type of material for its long service life, a high degree of noiselessness, and resistance to low temperatures.
In addition, the light weight of the tiles eliminates the high load from the roof structure on the foundation and walls of the house.
In other words, homeowners will be able to save money on reinforcing load-bearing structures, roofing and foundations. The complex structure of the tiles ensures excellent performance of the material.
