Roofing materials for a flat roof. Pros and cons of the materials used.
When choosing roofing materials, it is always necessary to take into account the main factors, namely:
1. What loads will act on the roof, taking into account not only the snow cover, but also the weight of the structure itself;
2. The service life of the material;
3. Design and building architecture;
4. Price and quality ratios;
5. Country manufacturer.
To arrange a flat roof, it is advisable to use materials that allow you to cover the entire surface plane without visible seams. These are mainly bitumen, polymer or made on the basis of mastic materials. They do not miss moisture and have low heat transfer.
Bitumen tile
To date, the most common roofing material for arranging a flat roof is bitumen tile. Its main advantage is the plasticity of sheets that allow it to be attached with minimal distances at the joints. In addition, the material is quite resistant to water and does not pass moisture. Of the disadvantages, you can distinguish fading under the influence of natural ultraviolet radiation and high combustibility of the material.
Falts roof
Less common material for a flat roof is a fold roof. It is made of sheets of steel, which are covered with a layer of galvanizing and painted with polymer coatings. But its main problem is mechanical damage. With deformation of the upper protective layer, steel is corrosed. Plus, there is a need for additional roof insulation, since steel has significant heat transfer. But on the other hand, this material is absolutely fireproof. At the same time, the low weight of the material allows you to install the roof without increasing the structure of the structure.
Copper or aluminum roofing sheets
The most expensive roofing material for today is copper or aluminum roofing sheets. Roofs with this coating look very rich. This material is used for any type of roof, including flat. The styling technology is no different from the installation of the fold roof. If you withstand all technical standards, then the service life of such a roof is calculated for more than ten years and in theory it may even exceed 100 years. Copper and aluminum sheets are environmentally friendly material, resistant to the environment, there is no need for constant cleaning or prevention of surface. But her price is much higher than other materials.
