Pressure washing a roof is one of the most damaging things you can do to it. High-pressure water blasts away the protective granules on asphalt shingles, accelerates wear, and can void your manufacturer's warranty. The ARMA (Asphalt Roofing Manufacturers Association) specifically recommends low-pressure soft washing as the only approved cleaning method for asphalt shingle roofs.
Our roof soft wash process uses a low-pressure application of professional-grade, biodegradable cleaning solutions to kill algae, moss, and lichen at the root — leaving your roof clean, protected, and looking years younger.
Asphalt shingles — the most common roof type in the Metro East
Metal roofs
Tile and clay roofs
Rubber and flat roofs

Black algae streaks (Gloeocapsa Magma)
Green moss and lichen growth
Mold and mildew buildup
General dirt and debris staining
Organic discoloration from tree coverage

A dirty roof can cause insurance companies to flag your home for inspection, lower your property value, and lead to premature roof replacement — which can cost $8,000–$20,000 or more. Regular roof cleaning at a fraction of that cost is one of the smartest maintenance investments a homeowner can make.
In the Metro East's climate — humid summers, heavy leaf coverage, and seasonal moisture — roofs are particularly susceptible to algae and moss growth. We recommend having your roof professionally cleaned every 2–3 years to protect your shingles and maintain your home's appearance.
