After the walls of the house are erected, the question arises about the choice of the material from which the roof will be made. Manufacturers offer several coating options.

  1. Metal tile, of course, beautiful and durable, but it is difficult to mount, and it is relatively expensive.
  2. Slate is almost never used, although only recently they covered the roofs. It is quite fragile and does not please the view.
  3. Euroshield or cellulose based onduline. Its drawback is that it is short-lived.
  4. Bituminous shingles, consisting of fiberglass material covered with bitumen. The downside is its fire hazard.
  5. Profiled sheeting has strength, durability, absolutely does not burn and does not require special skills for styling. Modern design and a wide range of colors.

How to choose the corrugated board for roof

The roof made of corrugated board will be the optimal "price-quality" ratio. The profile sheet is used in the construction of industrial, warehouse, retail facilities, private residential buildings. Many people are interested in the question of how to choose it. It is necessary to take this seriously, because the choice of your home depends directly on the quality of the house's covering, the preservation of heat and dryness.

Characteristics of corrugated board

The strength of the profiled sheet is influenced by the following characteristics: sheet thickness and corrugation height. According to GOST on steel sheet bent profiles with trapezoidal corrugations the thickness of the sheet can be from 0.1 to 0.6 mm, and the height varies from 10 to 114 mm( for the roof it is recommended 20-60 mm).The more these quantities, the correspondingly, and stronger will be the sheet. Strength characteristics also determine the number of stiffeners. Any type of profile sheet is marked with letters and numbers. Letters indicate the destination area, and the figures are the height of the profile. For example, a profile sheet for roofs has the designation "H", for roofing and wall - "HC."

If the profile is painted, then it is marked with the letters A and B. If there is a capillary groove on the profiled sheet that does not allow water to get under the roof at the junction of the sheets, then the letter R

Profile sheets by types of coatings

The type of coating is very important. Two types are distributed: galvanized and with a protective-decorative coating of polymers.

  • Galvanized zinced -U galvanized proflista has an undoubted advantage - its price, so it is mainly used in the construction of industrial facilities. In such profiled sheets, an aluzinc compound is used which combines the anticorrosive properties of zinc and aluminum. Profiled sheeting has a silvery surface and long enough to serve.
  • Profiled sheeting with protective and decorative coating For additional protection of the profile sheet, a polymer coating is applied to the galvanized sheet. Coverings such as polyester, plastisol, polyurethane( pural) are common. They differ in that they have different thicknesses and different resistance to unfavorable factors.

Layers of materials

The color of the coating can be chosen any. In addition to standard colors, there are sheets with the effect of "metallic", with a pattern of burnt ceramics or "under the tree", offset. The actual service life of coated profiled sheets is up to 50 years, warranty period is 10 -15 years without loss of color brightness and quality of the texture.

How much is the roofing profiled sheeting

The cost of roofing corrugated board is affected by a number of factors:

  • Corrugation height and sheet thickness,
  • Sheet length,
  • Colored or protective paint,
  • Presence of zinc coating,
  • Quality of polymer used for coating,
  • Brand of material from which the sheet is made,
  • Country of manufacture.

Given all these indicators, the spread of prices is quite large, from about 135 to 450 rubles per 1 sq.m.

What to look for when buying

If you buy a poor quality corrugated board, then in the future you will have to change the cracked coating. Therefore, when buying, you must pay attention to the following:

1. Appearance. Surface should be without roughness and small cracks, smooth. In color materials, the paint should not be peeled off. With easy bending, the corrugated sheet must not break, but return to the previous form. And when strong - keep the shape of the material.

2. Availability of a quality certificate for the product. You can also get feedback from consumers about the products.

3. Useful length of sheets. It, preferably, should be equal to the length of the ramp, becausewith short profiled sheets it is necessary to increase the number of lateral joints, which reduces the waterproofing. Therefore, you need to know the length of your roof plus add to it about 50 centimeters on each side for a place under the roof drain and for inaccuracy during installation.

It should be noted that if you want to make a solid, strong and durable roof, it is better to choose the profiled sheeting zinc-coated roofing with a polymer coating. In the case of construction of a temporary construction, it is better to use a material of aluzinc.
