Roof Cleaning in Montague, TX
The black streaks on asphalt shingle roofs in Montague County are Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in shingles. We use the ARMA-approved soft-wash method at low pressure — gentle on shingles, no granule stripping.
North Texas gets enough summer humidity — particularly in the creek and river drainages of Montague County — to sustain Gloeocapsa magma on asphalt shingles. The dark staining it leaves isn't just cosmetic: it increases heat absorption, shortens shingle life, and is often visible from the road. The ARMA-approved soft-wash treatment is applied at low pressure, which kills the organism and allows it to wash off over subsequent rains. We don't pressure wash shingles — that strips granules and is widely discouraged for asphalt roofs. North-facing roof planes and those shaded by trees show the fastest regrowth after cleaning because spores reintroduce from the surrounding environment. We'll tell you what to expect on your specific roof based on its orientation and tree coverage.
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 cleaning solution so it flows in the same direction as natural runoff.
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.
Roof Cleaning — Montague Specific
A cleaning company based in Montague doesn't build travel time into the quote or schedule. We're not routing from Denton or Fort Worth, and we're not fitting you into a territory that barely covers this area. When something needs a second visit or a follow-up, it's a short drive. For commercial accounts and property managers, that responsiveness is worth something. For residential customers, it means we can offer scheduling flexibility that larger, further-away services can't.
Roof cleaning is specifically about not using pressure. Pressure washing can strip granules and damage asphalt shingles — it's widely discouraged for asphalt roofs. The ARMA low-pressure soft-wash method kills the algae, and the results are visible the day of service. We'd rather give you the correct, gentle treatment that protects your shingles than a damaging high-pressure wash.
