Roof Cleaning for your Charleston property
Slate and standing-seam metal are common above the peninsula, and both punish a careless crew. We never put pressure on a Charleston roof - a low-pressure treatment kills the black algae streaks that harbor humidity and dripping Spanish moss breed, then rinses away without loosening a slate or scarring the seam.
Charleston, SC at a glance
Charleston's historic peninsula, from South of Broad to the harbor and the neighborhoods along the Ashley and Cooper rivers, sits in warm, salt-laden Lowcountry air. That humidity, heavy spring pollen, and marsh air feed mildew and algae on clapboard, stucco, brick, and slate and metal roofs. Because so many homes here are historic, gentle soft-washing - never high pressure on old mortar and wood - is the right way to keep them clean.
Care for the aging piazzas and lime-stucco facades below Broad follows the same soft-touch preservation standard championed by the Historic Charleston Foundation.
Exterior work on a protected downtown property often runs through the historic-district review overseen by the City of Charleston.
The peninsula's architectural heritage is the same one celebrated a few blocks up Meeting Street at the Gibbes Museum of Art.
How we get roof cleaning right
Those dark streaks running down Charleston roofs are not dirt; they are Gloeocapsa magma, a hardy algae that thrives in the Lowcountry's heat and humidity and slowly feeds on the limestone filler in asphalt shingles. Under a heavy canopy of live oaks dripping with Spanish moss, growth comes back fast, and pressure would tear granules right off the shingle. We never pressure-wash a roof. Instead we soft wash at less than garden-hose pressure, applying a treatment that kills algae, lichen and moss at the root so the roof rinses clean and stays clean far longer. The same careful chemistry works on the metal and slate roofs common downtown and in the Old Village, where a single misstep is costly. From Sullivan's Island to Summerville, we protect the roof's life while clearing the stains that age a house before its time.
Every Charleston job starts with an upfront, flat quote and finishes with workmanship you can count on.
