So true. Many amateur roof cleaners will use a standard power washer and create a costly mess for you to clean up. Leading shingles manufacturers emphatically state that our low-pressure wash method is the best method to clean roofs. A standard power washer should never be used in a roof cleaning. Using too much pressure will cause granule loss and reduce the longevity of your roof by up to 50%.
That’s too costly. Our methods are designed to eliminate black mold while preserving your most valuable asset — your home.
