Roof Washing & Cleaning in Huntsville, AL
A low-pressure roof wash can make your roof look brand new, without the granule loss pressure washing causes.
What Are Those Black Streaks on My Roof?
Black streaking on older roofs is a common sight throughout the southeastern US. These streaks are typically caused by the growth of algae and photosynthesizing bacteria, specifically Gloeocapsa magma. It thrives in warm, humid climates and is usually found on north-facing slopes and areas that receive less sunlight.
As it grows, Gloeocapsa magma breaks down the limestone in your shingles, causing premature shingle deterioration and loss of shingle granules. That puts extra strain on your gutter system and reduces your roof's lifespan.
How Our Roof Soft Wash Works
- Assess: we look at the severity of the staining, the pitch of your roof, and the condition of your shingles.
- Formulate: we adjust our chemical ratios to formulate a solution capable of instantly neutralizing the Gloeocapsa magma on your roof.
- Dwell: we let it dwell so the bacteria is killed to the root. The solution keeps working for up to 12 hours, then breaks down into salt and water, so your lawn stays happy and healthy.
- Rain does the rest: any remaining staining washes away with the next rain.
A chemical soft wash is the number one recommendation from the biggest shingle manufacturers for resolving roof stains.
Never Pressure Wash a Roof
Using pressure to clean your roof will cause granule loss, void your roof's warranty, and could cause water ingress. Pressure washing may remove surface-level stains, but bacteria growth under the shingle surface will ensure the stains quickly return.

Frequently Asked Questions
What causes black streaks on my roof?
Gloeocapsa magma, a bacteria that thrives in our warm, humid climate and grows mostly on north-facing slopes.
Is roof soft washing safe for my lawn and plants?
Yes. Our solution breaks down into salt and water after it's done its job, and we presoak surrounding plants, the same as on every house wash.
Will it damage my shingles?
No. We never use high pressure on a roof, because pressure is what causes granule loss and voids shingle warranties.
How long until the streaks are gone?
The bacteria is neutralized on contact. Any leftover staining washes away with the next rain.
