Black streaks on your North Olmsted roof are more than just dirt or the result of a tough winter.
If you see black streaks on your roof, then you have an aggressive algae known as Gloeocapsa magma growing on your shingles. This algae feeds on limestone in shingles, leaving behind telltale black stains. Algae, mold and mildew growth not only makes roofs look dingy, dirty and streaked, but can also cause
permanent roof damage
At Perfect Power Wash of North Olmsted, our professional roof cleaning team can remove the black streaks and leave your roof looking like new. As part of our roof cleaning service, we use a low pressure soft wash roof cleaning process to protect your shingles from damage. In addition to pressure washing, our trained, insured teams use algaecide and a preventative agent to kill and neutralize the algae that causes the black streaks, protecting your roof for the long term.
