Best Process To Clean Slate Roof by Thompson Roof Cleaning & Power Washing LLC

Slate Roof Cleaning requires a moderate level of chlorinated detergent. Extra surfactant is added to create more cling since slate roof shingles yield less surface tension. You want to spray on the product and have it stick. You need to solve the infection. A clean roof is actually a by-product of treating the infection of moss and algae. Black staining will dissolve immediately. Moss and lichen will die instantly but is left to decompose and dry out. When it fully dries out, the rain will finish the job. Slate roofs can be cleaned without pressure washing and without actually walking on the slate roof shingles. Again, the stains are alive and contagious. We want to fully sterilize the roof by treating the entire area. This is the best defense against the stain returning.
