Roof Cleaning
Ever wonder what those black streaks are on your roof? Can they be removed with a Roof Washing or Roof Cleaning?
The black streaks are mold, algae and lichen and, it is 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 or one where trees block the sun. This provides a few extra hours of morning dew or delays the evaporation of rain, providing a moist environment, which is ideal for mold and algae growth.
