Roof Soft Washing
Safe, low-pressure roof cleaning that removes black streaks, moss, lichen, and algae without the risk of shingle damage. We use professional cleaning solutions — not raw water pressure — to restore your roof's appearance.
Why Soft Washing — Not Pressure Washing — for Roofs
Roofing materials — especially asphalt shingles — are not designed to withstand high-pressure water. Using a pressure washer on a roof can dislodge protective granules from shingles, void manufacturer warranties, and accelerate weathering. It can also force water under shingles and into your home.
Soft washing is the industry-recommended method for roof cleaning. It uses low-pressure water combined with professional-grade, biodegradable cleaning solutions that kill algae, moss, lichen, and mold at the root — not just on the surface. Results are more effective and longer-lasting than pressure washing alone.

Frequently Asked Questions
We take precautions to protect plants, shrubs, and grass near the home before and during roof washing. We pre-wet vegetation and rinse thoroughly after cleaning. The solutions we use are biodegradable and designed to be safe when properly diluted and rinsed — but we're always careful in areas with sensitive plantings.
In most cases, soft washing results last significantly longer than pressure washing because it kills the biological growth at the source rather than just washing it off the surface. Results typically last one to three years depending on local climate, shade, and humidity. Homes in humid, heavily wooded areas may see regrowth faster.
That depends on the roof pitch, layout, and condition. We aim to minimize foot traffic on the roof whenever possible. Where roof access is needed, we take care to distribute weight appropriately and avoid unnecessary movement that could stress shingles. We'll discuss the approach for your specific roof before starting.
