Roof Cleaning in French Camp, CA
We clean French Camp roofs with a no-pressure soft wash that kills black streaks, moss, and algae at the root. Fog-heavy winters give roof growth a long season here, and older roofs tolerate zero abuse, so the method is chemistry at low pressure, never a pressure washer.
Fog country is roof-growth country
French Camp sits low in the valley near the river lowlands, and Tule fog parks over it for days at a stretch every winter. That sustained damp is ideal for Gloeocapsa magma (the bacteria behind black roof streaks), plus moss and lichen on the shadiest slopes. On the older shingle roofs common here, growth does more than look bad: it holds moisture against the roof surface and pries at shingle edges as it thickens, trading years off the roof's life.
Old roofs, gentle chemistry
An older roof has no granules to spare and no tolerance for blasting: high pressure on aged shingles is demolition, not cleaning. Our soft wash applies a sodium hypochlorite solution at low pressure, kills the growth where it anchors, and lets weather clear the dead material over the following weeks. Foot traffic is kept to the minimum the roof geometry allows. If a roof is too far gone to benefit, we say so instead of washing it.
The freight-dust layer
Roofs here also wear the same gray film the siding does: diesel particulate off 99 and I-5 mixed with field dust. It dulls the roof color and feeds the biological growth beneath it. The soft wash removes both layers in one treatment, and pairing the roof with a house wash in a single visit is the efficient way to reset the whole property's look at once.
Questions We Actually Get
Is it worth cleaning an older roof?
Usually yes, since killing moss and streaks extends what life the roof has and improves the whole property's appearance. We inspect first, and if replacement makes more sense than cleaning, we tell you straight.
Will you walk on my roof?
As little as possible, and on fragile roofs, not at all. Most application happens from ladders and eave positions. Older French Camp roofs get treated like the aging structures they are.
How long does a soft-washed roof stay clean here?
Several years, typically. The fog will keep trying every winter, but because the growth is killed rather than trimmed, regrowth starts from zero, and a light maintenance treatment resets it cheaply when streaks first reappear.
