The roofing roofing roofing is made of cardboard for the roof, it is first impregnated with light bitumen, and on top of it on both sides – with refractory bitumen to give plastic and waterproofing parameters.
Based on the fact that it is produced by rolls, then to eliminate sticking is sprinkled with dust mixtures. Sometimes, for the purpose of increasing strength characteristics, part on the outside is covered with sand with large grains painted in different colors. Recently, a roofing material reinforced with fiberglass mesh with integral reservation with the help of the surface of the surface from the outside has recently arose.
The roofing roofing roofing is quite plastic, cheap, owns the large properties of waterproofing, strokes to radiation of ultraviolet radiation, quickly falls even with the effort of 2 people. Again, due to its own cheapness, it is perfect for roofing conservation. If, for example, after the construction of walls on the ground floor and laying on them the overlap panels, the need for cryoconservation of the object again appeared, then again the excellent material than the roofing material, not to find it for this.
Unfortunately, the roofing material applies to the materials that burn, because the bitumen used for its production is considered a product of oil refining. Again, it is necessary to make a continuous crate under the roofing material, based on the fact that it is considered a sufficiently soft material with a small gap resistance, which increases the price of work. In addition, it is considered enough material for short -lived with a working period of not more than fifteen years.
Roofed roofing roofing – grounds for laying the material
Before laying the roofing material, make sure that the crate is continuous and rather dry. For work, we need the following tools: a sectional knife, a screwdriver, a hammer, a metal capacity for a mastic based on bitumen, a specialized brush with a long handle, a lamp for soldering work.
Actually, there are three options for laying roofing material:
Mechanical
Laying on mastic
Laying by the method of fuel (for roofing material, which is reinforced with fiberglass mesh)
The roofing roofing roofing in the first version is laid in this way – at first roofing rolls are rolled out, usually across the roof with a overlap of edges 10-15 cm.
Then we press it, clogging with nails or attaching it with self -tapping screws through the slats from wood to the frame. Steel galvanized stripes 2-3 cm wide. Stripes and rails are installed along the strip of roofing material, placing them in the middle and at the place of overlap of the edges.
But the roof repair by roofing roofing in this way is now used very infrequently due to the reduction in the working period of the material if compared with its laying the rest of the options.
