Safe, effective roof cleaning that removes ugly black streaks and extends your roof's lifespan
Book NowThose dark, unsightly streaks running down your roof aren't just dirt — they're actually a type of algae called Gloeocapsa Magma. This blue-green algae feeds on the limestone filler in asphalt shingles and produces a dark pigment to protect itself from UV rays.
Left untreated, this algae spreads across your entire roof, trapping moisture and accelerating shingle deterioration. It can reduce your roof's lifespan by up to 50% and significantly decrease your home's curb appeal and value.
The good news? Professional roof soft washing safely removes this algae and prevents it from returning for years — all without damaging your shingles or voiding your warranty.

We assess your roof condition, identify problem areas, and protect landscaping below.
We apply a biodegradable cleaning solution that kills algae, moss, and lichen at the root.
Using low-pressure water (like a garden hose), we gently rinse away the dead organic matter.
We inspect the results, clean up the work area, and ensure your complete satisfaction.
High-pressure washing can destroy your roof — here's why we use soft washing instead
Our soft washing method is safe and effective for all common roofing materials

Moss growth lifts shingles and allows water intrusion. Cleaning prevents leaks and expensive structural damage.
Common questions about our roof cleaning service
No. Our soft washing method uses low pressure (similar to a garden hose) and is the only cleaning method approved by shingle manufacturers. High-pressure washing WILL damage shingles — we never use it on roofs.

We recommend cleaning every 3–5 years for most homes. Properties with heavy tree coverage or in humid climates may benefit from more frequent cleaning.

No — soft washing is the manufacturer-recommended cleaning method. In fact, some warranties require periodic cleaning to remain valid. Pressure washing, however, WILL void most warranties.
