If a sheet metal roof is chosen as a cover, the builder for a relatively practical and inexpensive solution decides. Galvanized steel sheet is the most cost-effective variant and brings many advantageous properties with. The roof weighs little, is easy to assemble, durable and can be realized in many optical variants.
Materials and shapes
When a roof is covered with sheet metal, there are basically four alloying and metal species to choose from:
1. Anodized aluminum
2. Copper sheet
4. Galvanized steel sheet
As forms and optics, sheet metal can cover the roof in the following treatment and designs:
1. As smooth sheet metal railways
2. As smooth or shaped roof shingles
3. As a trapezoidal sheet
4. As a corrugated iron
5. With bonds or smooth
Costs and prices
Sheet metal covers except individual structural shingles are easier and faster mountable than other coverings. A galvanized sheet metal roof generates material costs of around twenty euros per square meter. For assembly, around five to ten euros per square meter must be added. The substructure of a sheet metal roof is different, but not more complex than that of any other roof.
Three central problems can be avoided
Corrosion and rust
Galvanized sheet steel is corrosion-resistant. Problems only arise when the zinc coating is or is damaged. The following checks and, if necessary, repairs ensure that a sheet metal roof can last up to thirty years:
- Thoroughly seal all drill holes and cut edges with zinc spray
- Check the roof for scratches at least once a year
- Make sure to avoid mechanical damage during processing and assembly
A tin roof makes noises when it rains that surpass other materials. Today, this problem can be almost completely eliminated by sound-absorbing measures such as special mats and fleeces.
A sheet metal roof is an airtight building skin without diffusion, such as that found in bricks. In order to eliminate the problem of condensation on the sheet metal roof, it is essential that the substructure is properly constructed with rear ventilation.Tips & Tricks With a small drone with a camera, you can check your tin roof more often with little effort. After a storm, flying parts of plants can cause scratches and flaking on the sheet metal.
