Roofbrite's Roof Cleaning Cure

Mosses, lichen and algae have now become a major maintenance headache throughout the UK. These external growths destroy decorative coatings and if left untreated will rapidly ruin subsequent coatings. They will also dramatically reduce the life expectancy of waterproofing compounds. Mosses, lichen and algae disfigure facing bricks and are a contributory factor to spalling of brickwork and concrete. In addition they cause erosion of the mortar joints.

Like all plant life, they hold and attract moisture, storing it within the brickwork or surface on which they are growing, giving rise to problems of water penetration. The fabric is further degraded by the excretion of acid.

Surface treatment by washes are ineffectual against such tenacious problems, since they only remove the visible surface growth, leaving behind the roots within the fabric. These roots will re germinate and grow within a matter of months.
