Roof Soft Washing in Columbus, OH

Black algae (Gloeocapsa magma) is common on asphalt shingles in Central Ohio. It doesn't just look bad — it can shorten roof life by holding moisture and blocking UV protection.

High-pressure washing can strip granules and force water under shingles. Our soft wash method kills the algae at the root with low pressure and professional chemicals designed for roofs.

Results are dramatic and help your roof stay cooler and last longer. Worried about your coverage? See our guide on whether roof soft washing voids your shingle warranty.

We are fully licensed and insured. Work is performed by experienced local crews — owner/crew bio, years in business, and credentials available from the renter once signed; ask for proof, recent photos, and references during your estimate.

Those dark streaks that start on north-facing slopes and under trees aren't dirt — they're living algae that feed on the limestone filler in asphalt shingles. Central Ohio's humidity and mature tree cover make them especially common in Lewis Center, Delaware, Westerville, Worthington, and wooded Columbus neighborhoods. Soft washing follows the low-pressure approach recommended by roofing manufacturers' guidance (ARMA): kill the growth, rinse gently, leave granules intact.

A typical roof soft wash: we confirm roof type and pitch safety, protect plants and gutters as needed, apply a roof-safe solution at low pressure, allow dwell time so algae dies at the root, then gently rinse. Pair with house soft washing when siding shows the same organic film. Still deciding on method? Soft washing vs pressure washing explains why high pressure stays off the roof. Curious about pricing?
