Roof Cleaning in
Powell, OH

Safe Soft Wash — ARMA Compliant

Powell's mature tree coverage throughout Scioto Reserve, Wedgewood Hills, and the wooded corridors near the Olentangy River creates consistent shade conditions that accelerate roof algae and moss growth. Our soft wash roof cleaning service in Powell removes the streaking and organic growth safely, documents the job with before-and-after photos, and delivers results that hold for 3–5 years in Delaware County's climate.

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.
