Those black streaks on Central Florida roofs are Gloeocapsa magma algae, and they're not just ugly — they eat the limestone filler in your shingles and shorten roof life by 3-5 years. Matata Roofing's soft-wash service kills the algae at the root without the pressure-washing damage most lawn-care companies cause.
Pricing band: $450 – $1,200. Typical 2,000 sq ft single-family soft-wash. Larger or steep-pitch roofs $900-$1,200.
We use a low-pressure soft-wash with sodium hypochlorite (the same chemistry the shingle manufacturers recommend) and surfactants that cling to the algae long enough to kill the spores. Results are immediate — black streaks gone in 15 minutes — and the kill keeps growth suppressed for 18-24 months.
What we won't do: pressure-wash your shingles. Pressure-washing strips the granule layer that protects asphalt from UV and voids most manufacturer warranties. Walk away from anyone with a wand and a turbo nozzle climbing onto your shingles.
Yes — it's the only roof-cleaning method approved by GAF, Owens Corning, and CertainTeed. Pressure-washing voids most warranties.
18-24 months for the visible streaks, longer if you add zinc strips at the ridge to suppress re-growth.
Not with the way we apply it. We tarp and pre-soak every plant within the spray zone, and we use plant-safe surfactant ratios. No plant damage in over 200 jobs.
