Get Rid of the Black Streaks for Good — Roof Cleaning in Orlando, FL
Those black streaks aren't dirt — they're algae eating your shingles. We soft wash them off at low pressure, treat the roof so they don't come back, and hand you back years of curb appeal.
Every Roof, Cleaned the Safe Way
Shingle, tile, or metal — soft washed, never blasted.
Streaks Gone, Curb Appeal Back
Orlando roofs, soft washed and streak-free.
Those Streaks Are Alive
Understanding what's on your roof is why we can keep it off.
It's algae, not dirt
Gloeocapsa magma feeds on the limestone filler in your shingles. Those black streaks are colonies of it — and they spread.
Pressure makes it worse
Blasting a roof strips the protective granules and voids most warranties. The algae comes right back on a damaged surface.
Soft wash kills the root
Low pressure plus the right algaecide kills the growth at the source, so the roof stays clean for years — not weeks.
Soft Wash: The Only Safe Way to Clean a Roof
The roofing industry, shingle manufacturers, and the ARMA all say the same thing: never pressure wash a roof. High pressure blasts off the ceramic granules that protect your shingles and shortens their life. We use the soft-wash method — very low pressure and a professional algaecide — to kill the algae, moss, and lichen at the root and rinse it away. Your roof comes out clean, your warranty stays intact, and the streaks don't come back.
- ✓Low pressure that protects the shingle granules
- ✓Professional algaecide that kills growth at the root
- ✓Keeps your roof warranty intact
- ✓Streak-free results that actually last

Roof Cleaning Questions, Answered
Will pressure washing damage my roof?
Yes — that's exactly why we don't do it. High pressure strips the protective granules off your shingles and can void your warranty. We only soft wash: low pressure plus algaecide, the method shingle manufacturers actually recommend.
Is soft washing safe for tile and metal roofs?
Yes. We tailor the approach to the material — barrel tile, flat tile, standing-seam metal — using the right pressure and treatment for each so we clean thoroughly without cracking tile or marking metal.
What are the black streaks on my roof?
They're colonies of Gloeocapsa magma algae feeding on the limestone filler in your shingles — not dirt. That's why a rinse doesn't fix them and why treating the algae at the root is what keeps them gone.
How long will my roof stay clean?
Because we kill the algae at the root rather than just rinsing it off, results last years, not weeks — and we back it with a 5-year no-streak warranty.
How much does roof cleaning cost in Orlando?
Most single-family roofs fall in a predictable range depending on size, pitch, and material. You'll get a free inspection and an honest, itemized quote before we book — often a small fraction of what a replacement would cost.
What areas do you serve?
We cover Orlando and Central Florida, including Winter Park, Baldwin Park, College Park, Lake Nona, Windermere, and Dr. Phillips. Not sure if you're in range? Just ask.
