Impregnating the Roof

Little material pores are plugged by impregnating the roof with a damp- and dirt-resistant substance. In this manner, fresh mosses won’t adhere easily. The impregnating substance seeps into the tiles, making it invisible after a while. This contrasts with a coating that only partially absorbs into the pores of the tile and instead clings to the surface like a film layer.

Coating the Roof

When coating, two coats of a colored or clear coating are sprayed over the roof. High pressure will be used throughout this process to ensure that the product fills all corners and openings. Particularly when the tiles no longer appear excellent after cleaning, the roof coating procedure is recommended.
