Roof: Roof Roof, Choose Material

Roofing is the roof shell, which protects the building from the penetration of precipitation. Roofing must be waterproof, with low thermal conductivity, and resistant to aggressive chemicals and precipitation. For the manufacture of the roof using a variety of materials - organic, metal or mineral. Each type of roof has different operational characteristics and service life, some can last 5-7 years, and some and 100. Consider each type of roof separately.

Organic .

These materials of the roof include ancient wood, straw, shingles, as well as modern materials - bitumen-polymer mixtures, roll materials, bitumen and other polymers.

Pros:

• They have a small weight.

Minuses:

• Weakly withstand ultraviolet rays and oxygen,
• Quickly aging,
• Are capable of decay,
• Are easily flammable.

Service life from 5 to 30 years.

Mineral .

This is a large group, which includes slate tiles, ceramic tile and cement-sand, asbestos cement sheets (slate) and tiles. Such roofing materials are also called natural.

Pros:

• Durable,
• Reliable,
• Do not rot,
• Do not ignite,
• Do not collapse from sunlight.

Minuses:

• Are very sensitive to temperature changes, especially within zero degrees,
• Have a significant weight,
• Are not used often because of the high cost.

Metal .

These include metal profiled sheets, metal, roofs from non-ferrous metals. For their production, copper, aluminum, galvanized and black steel, as well as their alloys, are used, which are painted with varnish, varnish, paint, polymeric materials. Copper sheets are the most durable. The service life of a copper roof from 50 to 100 years.

Have a small weight. In the construction of industrial, public and commercial premises use direct metal sheets. Usually for roof roof equipment with a slope of 14 to 20 degrees, sheets with a thickness of 0.5 to 0.8 mm, coated with zinc on both sides, are used. The installation of such metal sheets is carried out by folding technology, so this roof is called rebated. Only qualified workers should equip the roof. Increasingly, steel was replaced by titanium, copper, aluminum. Copper, although expensive, but has outstanding architectural expressiveness and high durability. Metal tiles are made of galvanized steel, and sometimes of copper. Can be coated with an additional anti-corrosion protection, in one or two layers of polymer coating. The polymer coating is resistant to ultraviolet rays and chemicals, can be matte, or shiny. Metal tile is durable and light, it is put on the roof with a slope of more than 12 degrees.
