Roof Cleaning · Summerville, SC
Pine straw piles into the valleys of a Summerville roof and holds damp against the shingle year-round, which is what feeds the dark streaks running toward the gutter line. We clear the needle load, then treat the algae with a no-pressure application so the streaks fade out and no wand ever touches the roof.
Summerville - 'Flowertown in the Pines' - sits inland among tall pines that keep yards shaded and damp, which is exactly what mildew and algae need. Pollen from the pines and heavy humidity leave homes, driveways, and porches green and grimy fast. Regular soft-washing keeps Summerville exteriors bright without high pressure that damages siding and wood.
Many Flowertown owners time a spring wash before the whole region fills up for Spoleto Festival USA.
The shops and offices along Main Street belong to the wider business community represented by the Charleston Metro Chamber of Commerce.

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 Summerville job starts with an upfront, flat quote and finishes with workmanship you can count on.
