Our roof cleaning process removes all mold and algae, which is what causes black streaking. The growth feeds on your shingles and can cause them to curl and blow off in harsh weather. Getting your roof cleaned every 5 years is a great way to save you tens of thousands on a new roof. We use a process called soft washing, which is a low pressure application of our industry leading soaps and solutions to the surface of the roof, that neutralizes all growth. Then we allow the rain over the next 10-40 days (depending on weather) to rinse the roof. Click the button below for a free quote!
