The main advantage of flexible bituminous tile is the ability to cover the roof of any shape: from a simple scope to a complex spherical and even with a variable curvature radius. However, this roofing material has many other useful properties.

The terms "flexible tile", "soft" and "bituminous", as a rule, denote the same roofing material. He appeared in North America called Asphalt Shingle. The word shingle translated from English means "shingle", that is, something piece, which is collected from individual elements into a single canvas. The words "flexible" and "soft" accurately transmit the main distinguishing property of this material, and "bituminous" - characterizes one of its main components.
Gonna flexible tile has a multi-layered structure. The basis is the fiberglass, impregnated with bitumen filler. The upper protective-decorative layer consists of mineral crumbs (basalt granulates are used in high-quality products, in low-cost slag). From the bottom side - small sandy sprinkle or protective film so that the shings do not stick during transport and storage.
In our market, a flexible bitumen tile represents many companies, including: "Deek Extrusion", Technonol Corporation (Shinglas Brand), Certainteed (Saint-Goben Concern), Icopal, Katepal, Kerabit, Tegola, CRZ (Brand ROOFSHIELD). Price 1 m² of roofing material - from 270 rubles.
Beneficial features
In addition to the use on the roofs of the most different degree of complexity, forms and configurations with a minimum waste, it is worth noting that the flexible tile creates a load on the base of about 10-25 kg / m². It is much easier for its "ancestors" - ceramic and cement-sandwaters, the mass of which is about 50 kg / m².

Pneumatic equipment will help to speed up the installation of flexible tiles several times.
The soft roof resistantly withstands high and low temperatures, the testimony of the house, erected for the polar circle, on the Far Eastern coast and in other climatic zones of Russia. The fact is that the basis of each shingle is impregnated not by the usual, but oxidized or modified bitumen. In the first case, it is artificially aware and less changes during operation. The range of operating temperatures of such materials from -70 to +110 ° C.
Polymers have been added to the modified bitumers. Most often used styrene-butadiene-styrene (SBS), thanks to which the high plasticity of the shingle is achieved even at negative temperatures, less often - attic polypropylene (APP). Such roofs have an excellent reaction to a hot climate. They are less susceptible to changes at high temperatures, mount them better in the warm season.
Important advantages of flexible tile - simple installation and maintenance. Damaged shings can be cut and replaced new.

Professionals have a few minutes for such an operation. In addition, this roofing material has a huge color palette that has no restrictions. Even if the customer does not suit the colors directory, manufacturers may pick up an exclusive shade to order.
If we talk about comfort, then during the rain and even more so hail under such a roof is much quieter and calmer than under a metal and other sheet. Noise reduces due to the structure of the material and the specifics of the roofing cake device. Flexible roof - safer others. Her rough surface prevents an avalanche-like snow out of spring, and therefore the drainage system, neighboring buildings, the green plantings will not suffer. The life of the simplest types of flexible tiles on average 25-30 years, high-quality roofing of solid producers - more than 50 years.
The main advantages of the multi-layer flexible tile "Technonikol Shinglas" - reliability and durability, increasing with each layer. For example, the overlapping coefficient in the three-layer material of the "Continent" series is more than five. This means that the shings overlap the roof in five layers. Therefore, such a roof has an unprecedented warranty period - 60 years. Multilayer material is distinguished by improved performance, rich colors palette, simplicity of laying and low waste. And most importantly, it is sold at an attractive price: the multi-layer tile of some manufacturers is often comparable in cost with one-layer others, and it is obvious that it is necessary to acquire the first economically more profitable. With such a roof, a country house may not be just high-quality and beautiful, this material is a find to implement the most unusual projects of roofs, including dome and Chinese pagodas.

How to avoid installation errors
Find a new flexible bitumen tile or reconstruct roof more convenient in the warm season. However, with a sudden cold attack, a gas burner or a thermal construction hairdryer will help to finish the work.
In this case, before installing the tile, it is keen in a warm room and served on the roof of five to six packs. And stacked after heating the bottom (adhesive) surface of the shingle. True, such works are more laborious and cost more.
Note that half of all problems with soft roofs - a consequence of installation errors. They seem to save them from good motives to save customer's funds. However, such "initiatives" lead to deterioration of the quality of the roof and reduce its life. For example, an OSP or Paneur is used, the thickness of which is less than the manufacturer required (9 mm). Fix one shoons with a smaller number of nails (less than five) and drive them off the line specified by the manufacturer of the material. Acquire components that do not comply with the requirements of quality and incorrectly establish them. In other words, the root cause of problems is the insufficient knowledge of the installation of flexible tile and low qualifications of workers. Of course, owning information, you can control the work of the roofers, but it is still better to entrust the installation of experienced specialists.
One is good and two - better
Flexible bituminous tile can be divided into single-layer and multi-layered. The last get a bonding two and more gears. Moreover, curly cuts are provided in its upper layer, and the lower is made in the form of a rectangular strip.

The advantages of the multi-layer shingle are due to its structure. It is thicker and stronger one-layer. It is difficult to damage and pierce what is important when laying and operating the roof. Multilayer tile without loss will take effect the impact of any, even hurricane wind (up to 150 km / h), which represents a serious danger to sheet iron, metal tile, erector. Mounting such a material is easier and faster than one-layer: there is no need to observe a certain offset of the upper gear relative to the bottom (to preserve the roof pattern), and the warranty period doubles or even triples.
So, if the roof of the country house is covered with flexible bituminous tiles, especially multi-layered, its owners may not think about what the weather is on the street, whether the wind is strong blowing, how much precipitation fell and how long the sun shines.
It is no secret that the flexible tile has a group of flammability of G4, that is, it is a stronger material. However, on flammability, the material of our company is referred to as a group B1 and B2 - difficult and moderatelylamented (respectively for roofs with a sprinkling or with a metal outer coating), and the spread of the flame - to the RP1 group, as non-propagating the flame due to the upper layer - basalt sprinkle. Of course, if a wooden house caught fire, no, even a non-combustible roof will save him. And directly from the surface of the flexible roofing of the fire will not happen, since the material does not support combustion and does not distribute the flame. Many tell stories about fires in homes that have taken from fallen Petard. But this could happen only if she fell inside the room. We conducted tests with firefoot, and they showed that set fire to the material covered with stone crumbs, it is impossible. If you put burning lambs on the flexible tile, while they are burning, the material melts, but when the lamps are roasted, the flame does not apply. So, the owners of houses covered with flexible tiles are nothing to fear.

Estimate the correspondence of the color of the flexible tile of the walls of the wall or the foundation of the country house, to choose the shape of the cutting of the shingle will help special programs on manufacturers sites
The appearance of the roof determines the configuration of the shingles: from simple rectangular cutting and classic hexagons to original rhombuses and shapes imitating an old dranco
Reliable coating of curly roofs with undershones, ridges, adjustments can only provide masters familiar with the specific laying
Mineral pads protects the bitumen layer from UV rays, gives the material an aesthetic appearance. The most fastened and less prone to burnout ceramized basalt granulate
Today, the flexible tile of natural tones is most in demand: brown, green, gray with a red tint
