Black Streaks on Your Roof? We Kill Them at the Source.
Those dark streaks aren't just ugly — they're a roof-eating algae called Gloeocapsa magma. Our soft wash process kills it at the root and restores your roof's appearance without damaging a single shingle. By choosing soft washing over replacement, you could save up to 90% of the cost of a new roof.

What Is Soft Wash Roof Cleaning?
Soft wash roof cleaning uses low-pressure water combined with specialized biodegradable cleaning solutions to kill algae, moss, lichen, and black streaks at the source on your roof. Unlike traditional pressure washing, which can void your shingle warranty and cause granule loss, soft washing treats the problem at its source.
The black streaks you see on roofs throughout Wisconsin are caused by Gloeocapsa magma — a type of cyanobacteria that feeds on the limestone filler in asphalt shingles. Left untreated, it shortens your roof's lifespan by years and drives up energy costs by reducing your roof's ability to reflect heat.
Our process is approved by shingle manufacturers like GAF and CertainTeed, meaning your warranty stays intact while your roof gets a second life.
A new roof in Wisconsin can cost $8,000–$15,000 or more. Soft wash roof cleaning delivers a like-new appearance for a fraction of that — saving you up to 90% compared to a full replacement. If your roof's structure is sound but the surface looks terrible, soft washing is the smart investment.
