What are the black streaks on my roof?????

These streaks are caused by a common airborne bacterial algae Gloeocapsa Magma living and feeding On limestone filler in your shingles.

In addition to the removal of algae/discoloration from fiberglass shingles, we also offer our roof cleaning services on both slate and tile roof surfaces.
