Roof Cleaning in Sterling Heights & Metro Detroit
Those black streaks running down your roof aren't dirt — they're a type of algae called Gloeocapsa magma, and once it takes hold, it spreads and darkens over time. Waterfall Exterior Cleaning LLC uses a low-pressure soft wash specifically designed to kill that algae at the root and safely restore your roof's appearance, without the damage that comes from high-pressure roof cleaning.
A clean roof isn't just cosmetic. Algae, moss, and lichen trap moisture against shingles, which can shorten the lifespan of your roofing material and lead to costlier repairs down the road. Regular soft washing protects your roof investment while immediately improving your home's curb appeal.
Why We Soft Wash Roofs (And Never Pressure Wash Them)
High-pressure washing on a roof can strip away protective shingle granules, force water under shingles, and void roofing manufacturer warranties. That's why Waterfall Exterior Cleaning exclusively uses soft washing for roof cleaning: a low-pressure application combined with a professional-grade, algaecidal cleaning solution that breaks down algae, moss, and lichen without blasting shingles or risking leaks.
