2120 Haystack Way, Myrtle Beach, SCYour roof cleaning specialist - What Are The Black Streaks On My Roof?Unsightly black stains or streaks on asphalt shingles are caused by a hardy type of algae called Gloeocapsa Magma. The algae feeds on the crushed limestone that is used in asphalt shingles. Rain spreads the algae down the roof causing the black streaks. These streaks are not only unsightly but cause the shingles to fail prematurely by not allowing the shingles to reflect heat properly.50% Of Roofs Are Replaced Due To The Way They Look.This is not because of their functionality. Half of the roofs ever replaced in the Southeast didn\'t need replaced, only cleaned. Just as mold and mildew can grow on your vinyl siding, wind blown algae can land and grow on your roof. Replacing your roof because of this algae is like replacing your siding instead of having it cleaned; it just doesn\'t make sense.Some roofing contractors don\'t know what these black streaks are, saying it\'s the asphalt showing through the shingles or that it\'s water stains. Some contractors may know it\'s algae but tell you it can\'t be cleaned without damaging the shingles. In either case, they may tell you that the roof needs replaced. This is not true if your shingles are still in good shape. The algae can be killed and removed properly without damaging the shingles using a low pressure chemical application (recommended by shingle manufacturers). Never use a pressure washer on an asphalt shingle roof, doing so will blow granules off the shingles and lessen the longevity of your roof.
