What Are Those Black Stains On My Roof?
Black staining on an asphalt shingle roof is caused by a bacteria that feeds on the limestone in the roofing shingle. Limestone is an organic mineral that is added to the roofing shingle to provide weight and strength. This type of bacteria can digest the limestone which slowly deterioated the shingle. It thins out the roof granules which protects the underlying membrane from harmful UV rays. Without these granules the shingle will prematurely crack and split.
What is the Best Method of Cleaning a Roof?
Many small businesses such as landscapers, window washers, pressure washing companies, and even roof installers are trying to cash in on this epidemic of bacteria and algae stained roofs. Without considering the damage it may cause many will simply high pressure blast the shingle. Not only does this not kill the bacteria, it also dislodges large amounts of roofing granules and prematurely reduces the life cycle of the shingle. Roof cleaning should be approached more like “pest control”. This bacteria is very contagious. Though the staining may appear mostly on the shaded sides of the roof, you can be assured that the spores creating the stain are spread throughout the entire roof. Like any other pest control job it is best to treat the entire area to be sure to get a 100% kill ratio on all of the organisms. This will insure a clean roof for an extended period of time.
