Do you see unsightly black streaks on your roof? What you see is Gloeocapsa Magma, a type of algae that grows easily in the environment provided by the shaded and northern sections of your roof. Moss & lichen are other nuisances that can wreak havoc on your roof. Moss is that green growth that, while certainly unsightly, can actually get under and lift up the shingles. Lichen is a fungus that looks like green or white dots.
Many homeowners see these issues on their roof and make the costly, and mistaken, assumption that the roof must need replacing when it probably just needs a professional cleaning. And at a fraction of the price of replacement, industry experts concur that routine cleaning can prevent deterioration of the shingles and extend the life expectancy of the roof. In fact, you could maximize your roof’s life span of 20-25 years by properly maintaining the exterior of your home.
Industry standard Roof cleaning methods require no high pressure at all. As recommended by shingle manufacturers, a 12volt electric motor is used to lightly spray a special algae and fungus-destroying detergent over the entire area.
