Soft Wash Roof Cleaning
Black algae, moss, and lichens are the most common forms of bacteria growing on your roof. Much of the organisms on a roof are there because of the warm, moist environment a roof creates, especially on the north and west sides of a roof. Micro organisms populate in an abundance growing so well that they begin to be noticeable to the human eye. Many roofing surfaces are made with materials that can be metabolized by the micro organisms. Shingles now contain limestone as a filler mixed into the aggregate of the shingle. Many of the algae, mildew and bacterias utilize this limestone as the base nutrient of their roof ecosystem and begin to feed on it.
