BLACKS STREAKS ON YOUR ROOF, MOLD, MILDEW,ALGAE, AND MOSS REMOVAL ON LONG ISLAND

What’s eating your roof? Gloeocapsa magma, commonly known as blue-green algae, is the technical term for the black streaks on your roof. Limestone is an additive used by asphalt shingle manufacturers to increase the weight of shingles. This limestone is an excellent source of food for blue-green algae. For blue-green algae to grow well, shady and humid conditions are essential, as well as access to food. On Long Island, they are typically found on north or northwest facing roofs, or on heavily shaded properties. These black streaks will eventually become moss if left untreated. Although black streaks on asphalt shingles are unsightly, moss can damage your roof significantly.
