With a great variety and innovations in the building materials market, roofing material has been firmly on the list for the past 50 years leaders in popularity among insulating materials used in construction.
Due to its qualities, the deposited roofing material is widely used in the repair and construction of roofs, for waterproofing.
Roofing material is a special waterproofing material in rolls. It includes fiberglass, or special roofing cardboard, which is first impregnated with a bitumen composition, then covered with refractory bitumen and sprinkled with special materials (it can be talc, sand or asbestos), so that the sheets do not stick together. A coarse dressing is applied to the outside - this prolongs the life of the roofing material.
Sometimes, during the manufacture, the manufacturer can complicate the composition of the roofing material with different polymers, which increase the material's resistance to low temperatures. This is usually in demand in the north, where the temperature regime is close to extreme. Such roofing material can withstand temperatures up to -50 ° C.
This material is hard to overestimate, because it has certain advantages:
It is worth noting that it also has several disadvantages:
All roofing material today can be divided into 4 main types:
! Important. The width of the web of rolled roofing material is standard and there are only three types: 100 cm, 125 cm and 150 cm.
The marking of roofing material is standard and regulated by GOST 10923-93.The symbol usually consists of three letters and three numbers. The first letter "P" means material, namely "roofing material".
! Important. Additionally, the marking may contain the letters "Ц" - colored or "Э" - elastic.
In order to choose the right quality roofing material, there are several rules:
Any creases, bends, cracks and holes are excluded. A slight tear is allowed along the edge of the canvas, but not more than three centimeters.
It can be determined by the color of the canvas in the section - it should be black with a slight brown tint. If there are light streaks in the cut, the material is most likely of poor quality.
! Important. When buying roofing material, you can run into a fake. We recommend buying material from manufacturers proven over the years - they value their reputation highly.
You can safely buy roofing material of the Technonikol, Aquaizol or Hydrol-Roofing trademarks. In addition, the price of these manufacturers is consistent with the quality.
Before proceeding with the installation of the welded roofing material, it is necessary to prepare the roof. First of all, the surface must be cleaned of debris and elements that may interfere with the installation process. If necessary, you can carry out wet cleaning.
Secondly, it is necessary to check the surface and, if there is any mechanical damage, to repair it.
Do not install roofing material over rotting elements, if any, they must be replaced.
It is not difficult to install the deposited roofing material, one person can easily cope with this. To do this, you need a gas burner, a propane-butane cylinder and a special hook. A burner is attached to the hook, the flame of which is directed to the lower part of the roofing material and melts it.
The roll is gradually rolled along the entire length of the roof.
It is important to observe a few rules when installing the welded roofing material:
