When building or repairing a roof, one of the most important aspects is the choice of material that will provide reliable protection against corrosion and other atmospheric influences. Metal tiles, thanks to their strength, lightness and aesthetic appearance, have become a popular choice for many homeowners.

However, for any roofing material, it is very important how you can preserve not only its appearance, but also its functionality. Precipitation can damage both the appearance of the roof and lead to leaks, followed by repairs, costs and additional work. We will have to look for replacement material and roofers. Metal tile, as one of the most popular materials, has zinc protection.

How is the metal tile protected from corrosion?

Corrosion, like rust, appears on metal after prolonged exposure to precipitation and moisture, as well as in the absence of protection against such effects. The metal tile has a layer of zinc in its composition, which is:

- protective
- anti-corrosion.

To protect the metal tile from damage and destructive processes, along with zinc, the polymer also helps, but it is zinc that is declared by the developers as a layer of protection against corrosion. Zinc is contained in the protective layer from 100 to 275 g per square meter. and with such a large range, it is important to choose the right parameter that will be optimal:

- in specific conditions of service, in particular, the climate is important,
- for the expected service life of the roof.
- in the composition of certain metal tiles.

Difference in cost

It is obvious that with the increase in the zinc component, the cost of metal tiles will also increase. Not every homeowner can buy metal roof tiles whose price is higher than his budget allows . Therefore, it is not always possible to protect oneself as much as possible from such damage to the roof, but the buyer should use all opportunities for this. It is not worth sacrificing zinc levels compared to:

- profile type,
- shade,
- the manufacturer.

You can choose the products of a not so well-known factory, but choose better galvanization. You can also choose a less popular wave, if you manage to even out the price of the product a bit.

Sample of high-quality metal roof tiles

To purchase material with better service prospects, try to choose products that:

- made of metal with a thickness of at least 0.45 mm,
- with galvanizing from 200 to 275 g/m2,
- protected by high-quality polymer.

Reliable and durable roof tiles have always been valued by homeowners. It is desirable that the metal tile has all parameters higher than average, then the roof will have an excellent appearance, and its functionality will not be lost over the years. And the correctly chosen material will ensure the durability and reliability of the roof for many years.
