Low-pressure soft-wash that lifts moss, algae, and black streaks without damaging your shingles.
Roof Cleaning in NW Georgia
The black streaks running down NW Georgia roofs aren't dirt — they're a hardy algae called gloeocapsa magma. It feeds on the limestone in shingles, lives off our humidity, and once it's established it spreads year over year. Pressure-washing a roof to remove it is a fast way to void your shingle warranty. Soft-washing is how it's actually done right.
We use a low-pressure soft-wash system with a roof-safe biocide that kills the algae, moss, and lichen at the root. The cleaner does the work — not high pressure — so your shingle granules stay on the roof where they belong. The streaks lift, the moss dies off, and the roof goes back to looking the color it was when it was installed.
Low-pressure soft-wash. Roof-safe biocide. Algae killed at the root, not just blasted off the surface.
What soft-wash roof cleaning includes:
- Property prep — Plants and shrubs along the drip line tarped and pre-rinsed so the runoff doesn't hurt landscaping.
- Soft-wash application — Roof-safe biocide applied at low pressure. The chemistry does the work — no high-pressure damage to shingle granules.
- Rinse + neutralize — Roof rinsed and the runoff neutralized before it reaches plantings. Property left as we found it.
- Free gutter top wipe-down — Because we're already up there — gutter tops wiped down and any debris cleared at no extra charge.
A lot of pressure-washing companies will offer to clean your roof. Most of them shouldn't. High pressure strips the granules that protect your shingles, voids your warranty, and the algae grows back within a year because the roots are still there. The soft-wash method is slower, safer, and the only one that actually solves the problem.

Black-Streak Removal in Fort Oglethorpe
A Fort Oglethorpe homeowner was about to list her house and the roof was striped with algae streaks. We soft-washed the whole roof in one afternoon and her listing photos were shot a week later.
How we handled it
- Property prep: Tarped the shrubs along the foundation, pre-rinsed the plants, set up the soft-wash pump.
- Apply: Roof-safe biocide applied at low pressure across all four roof planes, with extra dwell time on the north-facing slope.
- Rinse: Full rinse-down once the cleaner had done its work. Black streaks lifted off as expected.
- Final pass: Gutter tops wiped down while we were up there, runoff neutralized, tarps pulled, property walked.

Guards Solved a Decade of Climbing
We have three big oaks and a couple of pines, and I was cleaning my gutters four times a year. Matt installed the no-clog guards, threw in the free roof and gutter cleaning, and I haven't been back up the ladder since. Worth every dollar.

Honest Insurance Help After Hail
My adjuster said the roof looked fine. Matt walked it, found 20+ bruise hits, documented every one with photos, and met the adjuster on-site. Claim was approved for a full replacement. He didn't pressure me into using him for the work — that's why I did.

Roof Cleaning FAQs
-
It's an algae called gloeocapsa magma — extremely common in humid climates like NW Georgia. It feeds on the limestone filler in asphalt shingles and is what causes those vertical black streaks. Untreated, it spreads and shortens shingle life.
-
Pressure-wash uses high water pressure to blast surfaces clean. On a roof, it strips the granules that protect your shingles from UV damage — and most shingle warranties are voided by it. Soft-wash uses very low pressure and a roof-safe biocide that kills the algae chemically. It's the only method approved by major shingle manufacturers.
-
Typically 4–6 years before significant regrowth in NW Georgia's humid climate. If your roof has zinc or copper flashing (or we install algae-resistant strips after cleaning), it can last longer. We'll discuss your specific situation during the estimate.
-
Most single-story homes run $400–$700; two-story homes $600–$1,200. Pricing depends on roof size, pitch, accessibility, and how heavy the algae and moss growth is. Flat-rate written quote before we start.

Not with our process. We tarp and pre-rinse plants along the drip line, neutralize the runoff, and water-rinse anything that needs it before we leave. Plants stay healthy.
