DEMOSSING Mosses and algae are often the cause of accelerated wear of the roof. Because of this vegetation, water can easily infiltrate. They attach themselves to tiles, slates, corrugated plates, etc ... The roots penetrate the pores of the roof covering making it expand and crack. They absorb extra moisture and expand with frost, thus making the roof porous. Consequently, the mosses and algae penetrate still deeper into the roof covering, damaging the roof tiles and slates.
Preventative roof maintenance offers the following advantages: > It prevents water infiltration. > It prevents damage to the roof and opposes wear of the slates. > It prolongs the lifespan of your roof. > Your property rises in value. > Increased aesthetic value of your home.
