Why do homes in Sheffield Lake have unsightly black streaks on their roof?
Black streaks on your roof are not caused by dirt or the result of harsh winter weather. In fact, they are from Gloeocapsa magma, an aggressive limestone eating algae that feeds on the materials that make up shingles. The growth of algae, mold and mildew can make your roof look dingy. It can even shorten the lifespan of your roofing materials, creating an expensive repair for you and your family.
The experts at Perfect Power Wash of Sheffield Lake can remove the black streaks from your roof using our quick and efficient process. Our comprehensive cleaning process begins with a low pressure soft wash roof cleaning that includes the use of algaecide to kill and neutralize the algae. We then apply a preventative agent to inhibit the growth of algae, mold and mildew in the future.
