Our roof soft wash process
A proven four-step method designed for Duluth's damp climate, tree shade, and algae-friendly north slopes.
Inspect
We assess your Duluth roof — slope exposure, shingle type, moss vs. algae, and problem areas.
Treat
Low-pressure application with roof-safe chemistry kills algae and moss at the root — never high PSI on shingles.
Rinse
A gentle rinse removes dead growth while protecting granules and manufacturer warranties.
Protect
Results last longer because spores are eliminated — not just rinsed. Bundle with gutters to prevent immediate re-streaking.

Why Duluth Homes Develop Algae & Mold Faster
Roofs in Duluth collect Gloeocapsa algae and moss on north slopes where Twin Ports & North Shore shade and moisture linger — black streaks hold water against shingles and shorten roof life if left untreated.
- North-slope algae. Duluth roofs with tree cover or lake exposure see streaks years before south slopes.
- Moss before freeze-up. MN winters trap moisture under moss — soft wash treatment before snow is critical.
- Never pressure-wash shingles. High PSI voids warranties on Duluth asphalt roofs — low-pressure chemistry is the manufacturer standard.
- Bundle with gutters. Roof runoff re-streaks gutters fast — coordinating both on one visit saves Duluth homeowners a second trip.
