Those black streaks are Gloeocapsa Magma — a shingle-eating algae. Our soft wash kills it at the root, safely, without voiding your warranty. Serving Westerville and Franklin/Delaware County.
Westerville's combination of significant tree canopy, summer humidity, and north-facing roof exposure creates near-ideal conditions for Gloeocapsa Magma algae — the organism responsible for the black streaking you see on roofs throughout the community. Homes near Sharon Woods, beneath the mature oaks and maples in Cherrington Farms, and along the established corridors near Otterbein University are particularly susceptible. Our soft wash roof cleaning in Westerville kills the algae at the root safely.
The solution is not pressure washing your roof. High-pressure water strips the protective granule coating from asphalt shingles, voids most manufacturer warranties, and can force water under shingle laps — the exact damage you're trying to prevent. The ARMA (Asphalt Roofing Manufacturers Association) specifically recommends against pressure washing asphalt roofs.
The right method is a soft wash — low-pressure water delivery combined with a professional-grade algaecide that kills organic growth at the source. The treatment penetrates the shingle surface, kills the biological growth, and rinses clean without mechanical damage. Most treated roofs look dramatically improved within a single day and remain clean for 3–5 years.
Central Ohio's weather makes roof algae a near-universal problem. The combination of summer humidity, shade from mature trees, and freeze-thaw moisture cycling creates ideal conditions for algae and moss colonization. Most Columbus-area homeowners with asphalt roofs older than 5 years have some level of Gloeocapsa Magma growth.
We document every roof cleaning job with before-and-after photos. For roofs with significant moss or lichen growth, we provide a realistic assessment of what the treatment will achieve and what timeline to expect for full clearing.
