In recent years, especially in large cities,there is a shortage of useful space for the equipment of summer cafes or car parks. As one of the ways out in this situation, many entrepreneurs use flat roofs for these purposes, where the roofing material is used as a roofing material.
This material is deservedpopularity for many decades. Surfacing roofing is a roll waterproofing and roofing material, which has a synthetic base with two-sided application of modified bitumen. At its core, the welded roof consists of fiberglass or polyester, where the outer layer is protected by a foil, coarse, scaly, fine-grained powder or film. This coating protects the material from mechanical and atmospheric influences, blotting, ignition. Large temperature changes surfaced roofs withstand by adding special modifiers. The service life of such a roof can reach 30 years, with proper operation and timely preventive works. Welded roofs found wide application in civil and industrial construction in the construction of administrative, residential, industrial buildings.
The structure of the fusion roof is made withusing special gas burners. A very important point in carrying out installation work is to bring the material to a meltdown, but not until the moment of ignition. The welded roof, the installation of which must be made, can be partially or in the form of a continuous roofing carpet. Partial installation avoids the appearance of bubbles, but it will be difficult to find the place of leakage during its operation. The number of layers depends directly on the angle of the roof. Roofing must necessarily have four layers when the slope is inclined to 5
0. If the slope does not exceed 15
0, it requires the application of three layers, when exceeding 15 degrees, a single-layer fused roof is allowed.
Installation of roll roofing material canproduced on various basic coatings. It can be wood, flat slate, metal, asphalt concrete, concrete or reinforced concrete slabs. Before starting the installation work, the base is carefully processed. In some cases, an additional qualitative screed is required, in others it is sufficient to clean the roof of the roof of dust and dirt and treat it with a special primer to improve adhesion. If required, it is mandatory to make a slope using claydite gravel or sand. Particular attention during the installation of roofing work is given to the device of the roof abutment to the protruding structural elements and parapets.
On how competently producedpreparatory and installation work, on the quality of the roll materials used, directly depends on how much the surfaced roof will serve as protection of the building against the effects of atmospheric precipitation.
