Amazing aesthetic results are not the only reason to have your roof cleaned. The dark stains typically seen on the north face of roofs are a cyanobacteria that retains moisture, allowing moss, lichen, mold and fungus to grow and flourish. This bacteria feeds on the limestone filler in asphalt shingles. Moss and lichen break down the granular surface which is designed to protect asphalt shingles, shortening the service life of your roof.
