Reflecting on the purchase of roofing material, people often opt for metal tiles. This material deserves its popularity due to the reliability and ease of installation.
It is important that for such a roofing material as a modern metal tile, the price per sheet is very liberal, if not low.
The variety of varieties and brands of metal tiles makes a specific choice a little difficult. It can be greatly simplified if you know some of the nuances of production and operation.
What you need to know when choosing a metal tile
To get a reliable roof, you need to take into account the following features of the metal tile:
The thickness of the sheet plays a large role. Minimum value – 4.5 mm. If there are at least the slightest doubt, ask the seller to measure this parameter. Material of lower thickness will not be able to reliably withstand precipitation or load.
The type of polymer coating is also important, its quality. The cheapest is polyester. There are glossy varieties and matte. Such a metal tile will last up to 20 years. Regarding the safety of the color, then after 10 years of operation, the matte coating will lose 25-35% of its saturation. For a glossy version, this indicator is larger-35-45%.
Consider the amount of zinc in one square meter. Minimum indicator – 180 g, ideal – 275 g. In the first case, the service life is within 15-20 years, in the second-25-30 years.
Quality and geometry of sheet. All sizes must correspond to the marking. This is not only a high -quality evidence, but also a guarantee of normal installation and subsequent long -term operation. Gaps and bends greatly worsen the characteristics of the roof. It will also not benefit her of various thicknesses. This parameter is generally important for all modern materials, especially those where various plastics are used. It is included in this list and terrace decking .
The monotony of sheets indicates their high quality. Various shades – a sign of marriage. And the roof itself will look like a fused cloak.
Give up the use of the “grinder” during installation, as it violates the integrity of the zinc layer. There are special scissors for these purposes.
Pay attention to prices. High -quality metal tiles are not cheap. Whatever the seller tells you, but the lion’s share of the cost falls on the materials.
