Soft roof for the roof - types, pros and cons
Soft roofing is a technological roofing fabricated on the basis of fiberglass impregnated with oil bitumen. Visually, shingles imitate shingles made of wood chocks, which are rarely used in modern construction practice. Even the high cost of the roof of shingles does not cool interest to it, since the durability, attractive appearance and reliability of soft roof pays for all the costs of roofing work. In this article we will tell you about the pros and cons, the composition and method of installation of this new, but already popular roofing material.
Characteristic
Soft roofs are tiles and fiberglass, impregnated with modified bitumen with reserving powder from stone chips and a figured edge, which are laid overlapped on the roofing sheet to obtain an airtight coating. Продукция производится различной формы – овальной, полукруглой, пятиугольной, прямоугольной. Color spectrum битумной черепицы отличается завидным разнообразием, поэтому выбрать кровельный материал можно под цвет стен или, наоборот контрастный. Монтаж мягкой кровли выполняется 2 методами:
- With the help of self-adhesive bitumen layer located on the bottom surface of bitumen tiles. After removing the protective film, low-melting bitumen under the action of air temperature softens and adheres to the base of the roof. Roofing with such material is carried out only at a temperature of + 5 / + 15 degrees and low humidity, since in cold weather the bitumen layer must be heated by special equipment forcibly, which increases the cost of installation.
- With galvanized roofing nails with wide hats. This method of laying soft tile does not depend on weather conditions, so you can use it at any time of the year. However, with inept installation, shingles are often damaged, causing roof leaks. SNiP do not recommend attaching shingles to the base with nails, if the slope is less than 20 degrees.
Important! According to SNiP shingles suitable for the roof, if the angle of inclination is in the range of 15-25 degrees. The greater the slope, the better the water is removed from the surface of the roof, respectively, the risk of leakage is reduced.
Varieties
Soft roofing is a large group of roofing materials in which all coatings with a flexible, resilient structure are included. They differ in composition, form of release and method of installation. I make the following types of soft roof:
- Roll. Flexible roll roofing is represented by numerous types of roofing material, roofing felt and modern membrane materials. Roofing work on laying rolled materials takes less time, but they do not look as impressive as shingles. The cost of 1 square meter of such a roof, taking into account the lining layer starts from 500 rubles. According to SNiP, use of roll materials is recommended when the roof slope is at least 12 degrees.
- Piece. Shingle or piece shingles are individual tiles with a length of 1 m and a width of 30-45 cm, which are laid overlap. Roofing installation of a soft piece roof takes more time, however, due to the presence of a self-adhesive layer, they are performed without the help of heating equipment. The cost of shingles is much higher, especially if you take into account the cost of preparing a solid foundation, on which, according to the SNiP, it fits.
Important! All types of soft roof are considered as bituminous materials, but they are produced on a different basis. Roofing material produced from thick roofing paperboard suffers from temperature changes worse, it cracks in the cold, but it costs much less. Roof coverings based on fiberglass are much more resistant to temperature extremes, their cost justifies high quality, as well as long service life.
Composition
Soft roofing is a modern, technological material manufactured on the basis of durable polymers. The flexible, elastic structure gives this practical roof covering additional advantages when installing complex, multi-skid structures. By definition, SNiP shingles is a multilayer material, which includes:
- Fiberglass. The soft tile possesses a strong nonwoven basis from the pressed, chaotically located fiber glass. Flexible, elastic fiberglass provides the material resistance to temperature, cracking. Products, the cost of which belongs to the highest price category, are additionally reinforced with polyester, which makes the coating even more durable.
- Modified bitumen. The basis of fiberglass in the production process is impregnated with petroleum bitumen, enriched with polyester resins and synthetic rubber. Due to the impregnation of this composition, soft roof acquires high resistance to moisture and the effects of mold and putrefactive microorganisms.
- Booking topping. From above, shingles are sprinkled with colored mineral granules, giving color and a rough texture to the material. As a dressing that protects the bituminous coating from mechanical damage and prevents overheating of the roof, use granite, marble or basalt chips.
Important! The bituminous tile made on Construction Norms and Regulations possesses high operational qualities, effectively protects from penetration of moisture, wind and cold. As a rule, the cost of the material speaks about the quality of the product and its components.
Advantages and disadvantages
Each coating, including soft roof, has its advantages and disadvantages, which affect the possibilities of using and operating the roof. The cost of shingles is in an optimal ratio to the qualities of this material, so it is actively used in private housing construction. The flexible tile has the following advantages:
- Durability. Soft roof has a solid service life exceeding 70 years, which makes it a kind of record holder of harm to roofing materials.
- Maintainability. If damage appears on the shingles during operation, it is easily fixed by replacing just 1 tile, which significantly reduces the cost of roofing.
- Weather resistance Shingles has a high resistance to atmospheric moisture, temperature extremes and the effects of microorganisms, so it retains its original appearance and strength during the entire service life.
- Easy installation. Installation of a soft roof can be performed even with your own hands, since the fixing of the shingles takes place with the help of a self-adhesive bitumen layer.
- Low noise The roof with a coating of shingles effectively absorbs sounds, so that during rain and hail there is no strong noise.
Consider that shingles belong to flammable roofing materials, therefore, according to the requirements of building regulations, it is not recommended to install it on structures with a high risk of fire. Analyzing the pros and cons, we can say that a flexible tile is a practical and durable roof covering that pays for a whole lot of money.
Installation Features
The quality of the roofing of shingles depends on compliance with the technology of preparing the base and fixing the material. Therefore, the installation should take into account the following recommendations:
- SNiP prescribed to carry out the flooring of bitumen tiles on a continuous crate, made of particle board or sheets of moisture-resistant plywood. The base must be smooth, even, without knots or chips, so as not to damage the roof covering.
- Soft roof suitable for roofs with a slope of 15-25 degrees. It has a rough surface that retards the snow, so it does not require the installation of snow guard.
- Installation of soft roofing is done on the lining cake. If the slope of the roof is more than 20 degrees, then only the places that are particularly vulnerable to moisture (roof gutters, gutters, joints between the ramp and the wall) are protected with a lining.
- The material is laid at a temperature of + 5 / + 10 degrees in dry weather.
Experienced craftsmen note that compliance with the SNiP and the manufacturer’s recommendations for arranging the roof of flexible shingles ensures durability, durability and durability of the structure.
