Roof Cleaning in Galt, CA
Black streaks on Galt roofs are Gloeocapsa magma algae, and the town's long fog season is a gift to it. We remove it with a no-pressure soft wash safe for both comp shingle and tile. High pressure never touches a roof on our jobs, because it destroys shingles and cracks tile.
Fog season feeds roofs too
Gloeocapsa magma spreads wherever moisture lingers, and a Galt roof under Tule fog stays wet for days at a time. The algae feeds on limestone filler in composition shingles, streaking slopes black and shortening shingle life. On older homes near downtown, moss often joins in along shaded eaves and north slopes, and moss physically lifts shingle edges as it thickens. Both need killing, not blasting.
How we clean a roof without hurting it
Soft washing applies a sodium hypochlorite solution at little more than rainfall pressure. The algae and moss die on contact, streaks fade as dead material weathers off, and the roof surface keeps every granule and tile it had before we arrived. We protect and rinse landscaping, manage runoff at the gutters, and keep foot traffic minimal, especially on the tile roofs common in Galt's newer tracts.
The bonus: we see your roof up close
Most homeowners have not had eyes on their roof in years. While treating it we photograph anything worth knowing about, lifted shingles, slipped tiles, failing pipe flashings, moss-blocked valleys, and show you before we leave. Small roof problems in a fog climate become leaks fast, so catching them during a cleaning visit regularly saves Galt customers real repair money.
Questions We Actually Get
Are black roof streaks actually damaging or just ugly?
Damaging. The algae eats the limestone filler in shingles and holds moisture against the roof. Removing it is maintenance, not vanity.
Can you remove moss from my roof?
Yes. The soft wash kills moss along with algae. Thick moss mats get gently cleared after dying rather than scraped live, which would pull granules and lift shingles.
How long will my Galt roof stay clean?
Two to four years is typical. Galt's fog pushes regrowth toward the shorter end for shaded homes, and we offer a maintenance schedule that keeps ahead of it.
