Wrightsville Beach NC • Black Streak Removal • Bio-Based
Those black streaks running down your roof are algae eating into the shingles. We kill the algae at the spore level with bio-based soft wash treatment. No pressure damage, no warranty risk.
Those black streaks on your Wrightsville Beach roof are not dirt and they're not stains. They're Gloeocapsa Magma, a roof-eating algae that thrives in coastal humidity. It feeds on the limestone in your shingles. Left untreated, it shortens shingle life and pulls the color out of the roof.
Pressure washing the streaks makes the visible problem look better while making the underlying damage worse (it strips granules and lifts shingle tabs). Our soft-wash algae treatment kills the spores chemically with a bio-based solution. Streaks come off. Algae cannot regrow for years. No pressure damage to shingles. No warranty risk.
Algae treatment for Wrightsville Beach asphalt shingle roofs.
Gloeocapsa Magma algae. It thrives in humid coastal climates, feeds on the limestone filler in asphalt shingles, and shows up as dark streaks running down the roof. Very common in coastal NC.
Pressure washing removes the visible streak but strips shingle granules in the process. Most shingle manufacturer warranties prohibit pressure washing for that reason. Soft wash kills the algae chemically without damaging the shingles.
Usually 3 to 5 years if we treat it properly. Coastal {town} humidity will eventually let new spores take hold, but bio-based soft wash kills algae deeper than pressure washing ever could.
Bio-based, low VOC, no harsh runoff. Safe for kids, pets, plants. We pre-wet sensitive landscaping and rinse if needed.
No. Soft wash is explicitly the approved cleaning method for almost every major shingle manufacturer. Pressure washing is what voids warranties.
