Roll roofing, due to its operational characteristics, is widely used to cover roofs of any configuration. What are its views on the market, their advantages and how they differ from each other, this article will tell.
Roll coating provides:
thermal protection - retains heat in winter, protects from heat in summer;
protects the roof from exposure precipitation and wind ;
reliable waterproofing .
There are various materials for soft roofs, one of which is roll roofing. It has many advantages :
when repairing it is not necessary to remove the old coating, and it is enough to make patches in damaged areas ;
due to the content of bitumen has a good water resistance , as well as resistance to the effects of mold;
resistance to temperature differences , which gives a wide possibility of installation in any climatic zone;
good sound absorption ;
environmental friendliness - safe for human health are used in the production of the material substances;
high strength of the coating ensuring a long service life;
lightweight - which makes it possible to install without problems on any roof construction;
low price .
Roll roofing The material differs according to the method of mounting on the roof:
glued using bitumen or polymer mastics;
rolled material having on the back side of the self-adhesive surface, to install just remove the protective film and press to the base;
build-up on the roof under the influence of high temperature of the burner is most convenient for mounting on flat and pitched roofs.
Roll roofs - types are classified according to the following criteria : by type of base - fiberglass, asbestos, polymer, cardboard;
by type of device - with base and without base;
by composition of protective coatings - with film coating, foil-coated, with powder;
by production material - bitumen, polymer-bitumen, polymeric.

A classic type of rolled material for roofing is ruberoid, which has been used for a long time. Translated from Latin means "similar to rubber." The rolled cloth made of the cardboard impregnated with fusible bitumen. Both sides are covered with a layer of refractory bitumen. For the strength of the coating make sanding. It also reduces the stickiness of the material to the hands. The dressing can be fine-grained, coarse-grained, scaly, dusty. Impregnation of bitumen provides refractoriness of the material.
Roofing material can serve as a lining material, then it is marked with a letter "P", and also serves for the main roofing, it is designated by the letter "K". Installation of roofing material is carried out by the membrane method and fusion.
To find out what kind of roofing felt in front of you, you need to look at the marking. The first letter "P" is the name of the material, the second - indicating the type of use (roofing and lining, denoted respectively by the letters "K" and "P"), the third characterizes the type of sprinkling (dust "P", coarse-grained "K"). The next three digits indicate the brand of material. The higher the value, the denser the ruberoid. Since this material has good performance properties and cheap price, it is still used in construction.
Asphalt - cardboard without sprinkling, impregnated with bitumen is used as the bottom layer of the roof covering. It has good vapor barrier properties.
Over time, the ruberoid improved, instead of cardboard using fiberglass, fiberglass, synthetic woven fabric. The type of roofing material acquired a decorative character, thanks to the application of colored sprinkles. Create drawings, why the roof has the form of tiled.
To increase the degree of waterproofing and wear resistance, roofing material is glued together in several layers.
The price of roofing material is 19 - 25 rubles per 1 sq. M. m. This is the cheapest type of roofing material. One roll costs from 26 to 400 rubles.

Polymeric membrane materials produced in rolls are widely used in roofing. They provide good waterproofing. When installing do not require gluing to the roof surface. The cloths are glued together and fixed on the roof with dowels, fungi in the joints or in a ballast way - immersed in a layer of gravel or laid with paving slabs. Suitable for roofing of any shape, but flat roofs are preferred.
They are glued to the membrane for mounting on a domed roof. The seams between the sheets are welded with a building dryer. The membrane coating has the following advantages:
good waterproofing properties;
long life ;
simple and fast mounting .
Membrane roofing is divided into the following types:
polyvinyl chloride - containing a large amount of plasticizers, which impart high elasticity to the membrane . Elastic qualities facilitate installation work. The material is resistant to fire and sunlight. Membranes of different colors are commercially available, which makes it possible to use it in decorative quality;
TPO - a thermoplastic polyolefin membrane having a layered structure in which an ethylene-propylene layer alternates synthetic rubber with TPO. The base is reinforced with fiberglass or polyester. High-strength properties make it preferable to use the material in low-temperature conditions;
EPDM - membranes made of high-quality synthetic rubber. Polyester yarns are used for reinforcement. The membrane is fixed with glue.

At first glance, installing a membrane roof seems simple, but in fact the process requires a professional approach. Qualified craftsmen will provide reliable coverage.
The technology of laying membrane cloth is clearly shown in the video:
The cost of membrane cloth ranges from 290 to 500 rubles per 1 square meter. m. Installation of canvas depends on the type of base. The cheapest execution - installation on a corrugated flooring - 190 rubles, on a concrete base - 220 rubles, installation with a vapor barrier, mineral wool insulation costs 350 rubles.
Baseless rolled roofing coatings include plastic film. This material is extruded. Film thickness up to 0.2 mm is used as a lining layer on sloping and flat roofs.
The baseless coatings group includes materials:
rubber-bitumen - Brizol, Izol ;;
polymer bitumen - GMP.
They are characterized by a high degree of elongation, which gives plasticity and convenience in laying the roof. Izol is produced without polymer additives, denoted by the letters I-BD, and with plasticizers - I-PD.
The price of waterproofing fabric - Brizol is 150 rubles per 1 square. m.

The following materials are used as fusing roll material:
stekloizol - glass-coated or coarse-grained sprinkle. The material is frost resistant. It has good sound insulation properties;
composite bikrost - made on the basis of fiberglass, impregnated with modified bitumen on both sides, coated with a protective coating.
Stekloizol costs less — 50 rubles. for 1 square. m. The cost of GMP materials: "Bipol" - 101 rubles per 1 square. m, "Bikrost" with baby from 875 to 915 rubles for 1 roll, the cost of one square meter ranges from 50 to 100 rubles.
In the building materials market, roll-up roll roofing is represented by the following types of products:
TechnoNIKOL is a high-quality roofing material, represented by a wide range of coatings with a guarantee from the manufacturer 10 years. Use in low-temperature conditions is possible.

To facilitate roofing, I am releasing a self-adhesive roll roof in the form:
roofing material - made from polyester fabric , on the surface of which is applied a mixture of bitumen with synthetic rubber. From above topping from a coarse-grained mineral crumb. Some models sprinkle with colored granules to give a decorative look and improve the reflection of the rays, with the result that the roof heats up less in the sun. This type of roofing is well protected from mechanical damage and exposure to ultraviolet radiation. The bottom layer is protected from sticking with a protective film or foil. On the lower side of the material applied adhesive composition. Gluing occurs under the influence of sunlight. Roofing material, used as a substrate between the roofing layers, contains an adhesive base on both sides. Self-adhesive roofing is ideal for application to a wooden base, as it does not require heating;
bitumen-polymer - this type includes baseless material "Technicol" on a polyester base impregnated with a bitumen-polymer binder composition. The self-adhesive layer is applied on the back. On the front side, coarse dressing is applied to protect it. Designed for application on low-rise buildings, farm buildings with a flat and sloping roof.
Of the self-adhesive roof, Technonicol products have proven themselves well, prices are in a wide range from 923 to 3904 rubles. There are expensive types of roofing - Eisbar (Italian production), a roll of which costs 19,300 rubles.
The process of laying a soft roll roofing in this video:
Gluing the roll roof is using bitumen mastics. Installation is possible even on a wooden base. This is an inexpensive type of roofing, for which the traditional roofing material is used. Gluing is carried out by cold or hot mastic. Both types of heat, only the first to a temperature of 130 degrees, hot - up to 220 degrees.
