What kinds of roofs provide excellent weather in the house ?

Roll materials

Roll roofing are made on the basis of bitumen-polymer and bitumen materials with reinforcing basis.The most common types of this roofing is roofing felt, asphalt and roofing felt.All of them are united by the fact that the foundation provides cardboard.The main drawback of this material is short-lived, unstable to decay and weak frost.

In this regard, they are used in places where there is no possibility to use other materials.Lies such as roofing waterproofing carpet in 3-4 layers.Roof-based polymer in the bitumen composition has a polyester which prevents putrefaction.Another type of roof - mastic.This polymer membrane is formed directly on the roof.This coating is obtained by applying to the surface (usually concrete) zhidkovyazkih materials that cover the surface of a solid layer.

Mastic adheres perfectly to concrete, metal, and especially well suited for the treatment of adjacent nodes.Roof mastics are resistant to corrosive conditions, oxidation, corrosion is not exposed to changes in temperature and transferred to -40 to +100 degrees Celsius.In addition, they are flexible, durable and have a light weight.

Note!Mastic as a coating for roofs particularly well in climates with harsh climates.

Sheet kinds

Types of roofs roof also represented a large group of sheet materials.The first in this area were the sheets on the basis of asbestos and cement (slate), then the sheets of galvanized steel and aluminum, and the latest - metal.

Slate - a durable material that can serve up to 50 years.It is made by mixing korotkovolnistogo asbestos and Portland cement.To extend the life of slate, it is covered with special paints.Paint material increases the ability to repel water and increases its resistance to frost.

Note!There is a kind of slate - evroshifer which deprived many drawbacks of the conventional material, but its service life is twice less.

steel and aluminum galvanized sheet - it is much more durable and durable material than slate.Such sheets can be used for many years (more than 50).However, if it unfavorable factors, such as acid rain, the service life will decrease, as will a more intensive metal corrosion.For additional protection, the surface is painted with different compositions.

Metal - is a type of steel sheet coated with a polymer coating.The material is subjected to profiling, to get the picture that simulates a real tile.The sheet consists of several layers (polymer passivation layer, primer), which provides reliable protection from moisture, oxidation during cutting and mechanical damage.The main advantages of a light weight, easy installation, long life and environmental friendliness.The disadvantages include the ringing of the coating in the rain and snow shifts.

piece roof - difficult, but securely

last group of roofs - piece materials.This is one of the oldest ways to cover the roof.Consider what are the types of roofing materials from the piece:

• Ceramic tiles - reliability, durability, fire resistance and temperature changes.Its main advantage is the low thermal conductivity and good noise absorption qualities.The disadvantage is certainly true of its heavy weight, which makes it necessary to build a strong structure trusses;

Note!Great weight of the roof means better resistance to wind gusts.

• Cement-sand tile - a kind of roof tiles, which in all respects it is similar, except for a smaller period of operation.Weight it a little less, but to put it on the lightweight construction is still not recommended;
• Metal tiles (not metal) - is profiled galvanized metal sheet coated with a surface coating of mineral granulator.It is an imitation of ceramic tiles;
• soft tile - it's thin, different shapes tiles of glass fiber, asbestos cardboard impregnated with bitumen, and coatings of mineral aggregate.This material is ideal for mounting on the roofs of complex configuration.It is light enough, and the service life is 30-50 years.
