Moss removal
Once your roof has been thoroughly cleaned, moss removal is the other essential maintenance step. It consists of applying treatments to overcome mosses and lichens and prevent their reappearance, at least for a long time.

Avoid the use of bleach or chlorine which may damage the coating of your roof in the long term.
Copper wires are also effective in controlling moss. In contact with rainwater or snow, the copper will dissolve and cause a chemical reaction generating copper sulphate.
