The metal tile is an excellent roofing material with reliability, strength, durability and excellent aesthetic appearance. In order for the roof of the house to reliably protect the building from the weather and last for a long time, it is necessary to correctly install the metal tile.
There are common mistakes when performing this type of work, which can be avoided by the following recommendations.
Firstly, it is unacceptable to install the roof without first leveling the battens. This is a very common mistake. As a result, the joints of the sheets will be visible, and the tightness of the coating will make you expect the best. Ultimately, these flaws will lead to the premature end of the life of the materials.
In some cases, the installation of metal tiles is carried out for waterproofing, without performing counter-battens. You should not rely on the assurances of insufficiently experienced installers who say that this can be done. Laying the roof for waterproofing without a counter-lattice will also prematurely disable the coating.
A very common blunder is the use of a grinder with an abrasive wheel for cutting metal tiles. Such an action burns the polymer at the cutting points, and it should protect the metal from premature wear. In addition, red-hot filings, scattering in different directions, spoil the coating, sticking to its surface. As a result, rust begins to form in damaged areas.
Carrying out installation of a metal tile, cutting is not allowed using a grinder equipped with an abrasive wheel. This leads not only to polymer burning, but also to the zinc layer. As a result of violent corrosion, rusty smudges appear.
When carrying out such actions, the product is withdrawn from the warranty, and no manufacturer will accept claims.
Correctly cut the material should be using scissors or a hacksaw for metal. Sometimes you can use a hand saw equipped with carbide teeth. Sawdust formed after work must be carefully removed with a broom, being careful not to damage the polymer layer.
High-quality technology for mounting metal implies the use of special screws. Otherwise, even the most expensive coating will disappoint during operation. Self-tapping screws must have a sealing washer made of rubber material. The rubber washer may dry out over time, as a result of which the roof will lose tightness and rigidity.
Installation of the folded roof should be performed in the lower parts of the wave using self-tapping screws with a length of 20 to 35 mm. If the metal tile is fixed on top of the wave to the crate, then this, in addition to unnecessary noise, will cause unreliable fastening.
When installing the roof, the use of mounting foam is unacceptable. To fill the void between the ridge and in other places where debris and snow can fall, as well as to arrange thermal insulation, it is necessary to use a special sealant.
Like any work, the installation of metal tiles requires skills and certain experience, therefore, in order to avoid mistakes, it is better to turn to trusted specialists.
