Roof Cleaning in Montague, Bowie, Wichita Falls & North Texas
The black streaks on your roof are Gloeocapsa magma — a cyanobacteria that feeds on limestone filler in asphalt shingles and spreads by airborne spores. We remove it with an ARMA-approved low-pressure sodium hypochlorite treatment that doesn't strip granules or void your manufacturer warranty. Serving Montague, Bowie, Wichita Falls, and North Texas.
Pressure washing a roof strips granules and voids most shingle warranties — roofing manufacturers will say this explicitly. The ARMA-approved method for algae removal is sodium hypochlorite applied at low pressure, rinsed thoroughly. That's what we use. The black staining doesn't disappear the day of cleaning — the organism dies, and the dead cells wash off gradually over the next few rainstorms. If you're expecting an instant result like a pressure-washed driveway, that's worth knowing upfront. The roof will be noticeably cleaner within a few weeks of rain.
What Our Roof Cleaning Service Covers
Low-pressure application — never a pressure washer on shingles
We apply the cleaning solution at under 200 PSI. High-pressure washing strips granules, voids warranties, and doesn't solve the problem better. The chemistry does the work.
Sodium hypochlorite at the ARMA-recommended concentration
1–3% sodium hypochlorite with surfactant — the concentration that kills Gloeocapsa magma without damaging the shingle surface. Too weak doesn't work; too strong risks surface effects and poor rinsing.
Gutter flush included with every roof clean
Roof cleaning dislodges organic debris that washes into gutters. We flush every downspout after cleaning so you don't have blocked gutters two weeks after the job.
Moss and lichen treatment
Moss holds moisture against shingles and lifts edges. Lichen bonds chemically to the surface and resists treatment more than algae — heavy lichen may need a follow-up visit to fully release. We tell you what to expect before we start.
Minimal roof foot traffic
Every unnecessary step on the roof is granule wear. We use extended wand reach to minimize walking on the surface and soft-soled footwear when we do walk it.
How Roof Cleaning Works
Pre-wet landscaping below the roofline
Everything in the runoff path gets thoroughly soaked before the cleaning solution goes on.
Apply solution from ridge to eave
We work down the slope, applying the sodium hypochlorite mix so it flows in the same direction as natural runoff. Dwell time is 10–20 minutes.
Low-pressure rinse
Gentle rinse from ridge down. No high pressure at any point. Some dead algae washes off now; the rest comes off in the next few rainstorms — that's normal.
Gutter flush
After rinsing the roof surface, we flush every gutter channel and downspout to clear the organic material that's washed down.
Why Choose Clean Freak for Roof Cleaning?
Roof cleaning is specifically about not using pressure. Every major shingle manufacturer says pressure washing damages shingles — GAF, CertainTeed, Owens Corning. The ARMA low-pressure method kills the algae, and the dead cells wash away over the next few rainstorms. The roof might look slightly streaky right after cleaning; give it two or three rain events and it clears. We'd rather give you the correct result on the right timeline than a visually dramatic but damaging high-pressure treatment.
