Roof Cleaning for your Greenville property
The black Gloeocapsa streaks on Greenville shingle roofs show first on the north slopes shaded by the mature oaks around North Main and Cleveland Park. We soft wash at low pressure to kill the algae and lichen at the root, never blasting the granules, so the color returns and the streaks stay gone through the humid Upstate summer.
Greenville, SC at a glance
Greenville has transformed its downtown around Falls Park on the Reedy and the Liberty Bridge, nestled in the foothills of the Blue Ridge. The Upstate's heavy spring pollen, warm humidity, and tree cover leave homes, decks, and driveways coated in green film, mildew, and black roof streaks. Regular soft-washing clears the buildup without damaging siding or older brick, keeping Greenville homes bright through pollen season.
The Liberty Bridge and the tumbling falls that anchor downtown draw crowds to Falls Park on the Reedy.
Homeowners can confirm exterior-work and runoff rules with the City of Greenville.
Upstate weather swings and heavy pollen counts get covered week to week in the Greenville Journal.
How we get roof cleaning right
Those black streaks running down so many Greenville roofs are not dirt, they are Gloeocapsa magma, an algae that feeds on the limestone filler in asphalt shingles and thrives in the Upstate humidity. North-facing slopes and anything shaded by the pines around Travelers Rest or Paris Mountain go first, because they hold moisture the longest. We never pressure wash a roof. High pressure strips the protective granules and voids most shingle warranties, so we soft wash with a low-pressure application that kills the algae, mildew and lichen at the root and lets rain rinse the stain away over the following weeks. From the older neighborhoods off Augusta Street to newer subdivisions in Greer and Simpsonville, the treatment restores the shingle color and slows regrowth so the streaks do not race back the next humid summer.
Every Greenville job starts with an upfront, flat quote and finishes with workmanship you can count on.
