What better roof: metal, asphalt or clay?

Roof construction — This protection for buildings and tenants. First, they withstand the vagaries of nature — cold, moisture and wind. The constituent elements of the roof — waterproofing, insulation, drainage system, windscreen, perform a specific function. The material used to cover the roof must withstand the attack of bad weather and participate in the construction design registration. In this regard thereto are special requirements.

The basic requirements

Of paramount importance is the durability, strength of the coating, the possibility of using the material for the complex designs and ease of installation. From the weight of the material depends on the availability of additional strengthening of the foundation and structure. The first coating specifications determined by the quality of the material that is used as a raw material in its production.

Metal roof

Today, the most popular roofing material — metal. Among the main features that explain its relevance, is to provide exceptional strength and durability. For the consumer, these are also important characteristics inherent in the metal roof as ease of installation and low weight. Most often used for arrangement of steel roofs. Today you can buy a wavy shaped, smooth steel sheets and sheets that mimic the traditional tiles.

In addition to roofing materials in individual building the requirements for creating a complete image of construction, which is crowned by a roof. This explains the wide popularity of modern metal roofing materials in the construction market. The main guarantee of long life of the coating — the original quality of the metal. For example, Metal Ruukki is made from galvanized steel, having a thickness of half a millimeter.   In addition to the zinc layer, on it there is a special polymer coating that prevents corrosion and allows you to solve the problem with the external design of the roof.

Consumers purchasing a metal roof Ruukki, get complete package, including everything necessary for a successful installation. This helps reduce costs thanks to the precise elements of the mutual satisfaction of roofing system, that is, saving labor costs. Depending on the type of polymer coating material is determined by the resistance to mechanical stress, corrosion and UV. The production technology provides a huge selection of metal on the profile of the wave, color and form elements.

Bitumen roof

One group of roofing materials — Bituminous coating. With oxygen saturation bitumen improves its initial indicators of ductility and heat resistance. Available modifier improves the properties of raw materials affecting the flexibility of the material, its durability and heat resistance. But their application affects the cost of the coating. Variety reinforcing layer affects the mechanical properties of the coating, for which often acts fiberglass. The special resistance of the coating to mechanical stress is obtained from the use of fiberglass and polyester. One variety of materials for pitched roofs and created on the basis of bitumen, — corrugated sheets. They are sometimes referred to « evroshifer ». Their composition contains a thermosetting resin, mineral substances and pigments. They are distinguished by low weight and easy installation. Among the physical and mechanical properties should be made low water absorption, high chemical, climatic and biological stability. The plasticity of the material allows use it for curved roofs. This material manufacturers offer a guarantee for fifteen years. It belongs to the middle price range.

Shingles

Another roofing, created on the basis of bitumen, — Shingles. Roof with this material is formed by stacking tiles, whose shape is different. Fixing soft tiles made using special roofing nails or self-adhesive layer applied. The main advantage of the coatings in the piece performance — easy maintenance and easy installation. The service life of up to fifty years. Often the outside of the roof tiles made of basalt spreading, which protects the tiles from damage and exposure to water. Many manufacturers in the search for design solutions are constantly experimenting with the material. For example, a coating of an alloy of zinc, titanium or gold-plated and patinated copper, characteristic of shingles Tegola, determines the reliability of property and social status. The cost of these spectacular solutions above the cost of shingles having ordinary basalt cover. When installing the roof with shingles require the use of a solid crates or plywood sheathing waterproof. This increases the cost of works associated with the arrangement of the roof.

Natural roof

For the production of natural tile used sand and clay. The most famous is considered to cement-sand and ceramic tiles, natural. These species are characterized by long life — lifespan up to a hundred years. It provides high resistance to adverse environmental effects. Also, natural tiles are low thermal and sound conductivity. But it has some drawbacks, particularly time-consuming process of laying and the high weight of the roof, which requires additional strengthening bearing structures. The raw materials for the ceramic tiles used clay, the production of which requires firing. The result is a material that is characterized by high durability and frost. To   production of cement-sand tile is used cement, quartz sand and pigments. Today, a large selection of roofing materials helps the consumer to choose a material that meets any purchasing power. Choosing roofing is recommended in view of the life of the construction and aesthetic characteristics of the coating.
