Taking the sky on your head is not just an ancient fear. Roofs are indeed exposed to many dangers that can damage them and cause significant damage to our interiors. It can be the fall of dead leaves in the fall or mosses, climbing plants, tree branches, frost, etc. These elements can degrade covering, impairing the spontaneous flow of water, and causing the tiles to move.

As water goes literally everywhere, it can also reach the electrical system. But not only: “infiltration can cause the wood to rot, weaken and cause the ceiling to fall. If water enters the insulation, this will create thermal bridges because the insulation characteristics of the insulating products are lost by the ‘air…’ develops Olivier Lafore, Edilians Marketing Communication and After-Sales Service Director.

You haven’t been paying attention, and it’s the tile? Do not panic. Let’s first recall a golden rule on which professionals insist: do not tempt fate!

By playing the apprentice roofer , the individual puts himself in danger and takes the risk of worsening the state of his roof by walking on it.

As for how to secure the roof while waiting for repairs, again, caution is advised.”There is still the good old basin technique, but it’s very archaic. As for installing a tarpaulin on the roof, once again, it’s far too risky. Safety first!” insists Olivier Lafore.
