Ever wonder what those black streaks are on your roof?
Those black streaks are mold, algae and lichen and they are actually living on and eating your shingles. In the late 1980s, roofing manufacturers reformulated asphalt shingles, removing some asphalt and replacing it with crushed limestone. This limestone is the food source for the algae. Left untreated, this can shorten shingle life and increase electric bills due to the loss of the reflective granules.
The black streaks usually begin on the north side of the roof the side where trees block the sun from reaching it. This provides a few extra hours of morning dew or delays the evaporation of rain, which provides a moist environment — which is ideal for mold and algae growth.
