Roof Cleaning in Mobile, AL & the Bay Area
The dark stains running down shingles all over Mobile are a bacteria called Gloeocapsa magma. It eats the limestone inside asphalt shingles, spreads roof to roof on the wind, and keeps your shingles damp and hot. The longer it feeds, the more life it takes off the roof.
The fix is a soft wash — no pressure at all. We apply the treatment shingle makers approve, let it kill the growth, and let the streaks release on their own. Your granules stay put, your warranty stays intact, and the roof stays streak-free for years instead of weeks. We treat shingle, metal, and low-slope roofs on both shores of the bay.
What roof cleaning includes
- Soft-wash treatment for asphalt shingle roofs
- Gloeocapsa magma (black streak) elimination
- Lichen and moss treated where oaks shade the roof
- Metal and low-slope roofs cleaned to suit the material
- Plants and grass below shielded and rinsed
- Downspout runoff managed during treatment
- Zero high pressure at any point
How it works
Roof look-over
We check shingle condition, pitch, and how far the growth has spread before quoting.
Written quote
One firm price in writing. If a roof is too worn to clean safely, we'll tell you that instead.
Treat, don't blast
The solution goes on at low pressure and stays on the roof to do its work.
Fade-out period
Heavy streaks keep fading with the next few rains as the dead growth lets go.
Why Bay Area roofs streak so fast
Warm nights, wet air, and shade are everything roof algae wants — and the central Gulf Coast supplies all three most of the year. Streets under live-oak canopy get hit hardest, and once a couple of roofs on the block show streaks, the wind carries spores to the rest.
There's a practical reason to handle it beyond looks. Ahead of hurricane season, insurers and inspectors pay close attention to roof condition, and heavy streaking makes a sound roof photograph like a failing one. A clean roof takes that question off the table — and runs a touch cooler in August, too.
Roof Cleaning questions
What do roof cleanings run in the Mobile area?
Roofs sit toward the higher end of our pricing, because of the size of the surface and the care and access the work takes. Pitch, height, and how much moss and streaking has built up set the final number. We put it in writing before we set up.
Why can't I just pressure wash the roof?
Because pressure strips the granules that protect shingles from the sun. That ages the roof fast, and most manufacturers void the warranty over it. A soft wash removes the streaks without touching the granules.
Will my landscaping be okay?
Yes — protecting it is part of the job. We soak the beds before treatment, manage what runs off the roof, and rinse everything again before we leave.
The streaks are still faintly visible after cleaning. Is that normal?
It is. The organism dies the day we treat it, but the darkest staining releases gradually with rain. Give it a few weeks — the fade continues on its own.
