California insurers now flag roofs from aerial photos
Fox Roof Cleaning sees carrier letters that allow up to 75 days to remove moss, algae and debris from a roof.
Carriers writing in California review most homes with aerial imagery before renewal. Software scores the roof for moss, lichen, algae streaks, debris and overhanging branches. A poor score brings a conditional renewal, an inspection request or a non-renewal notice.
Homeowners in San Francisco and Fairfield have been dropped over roofs that only needed cleaning. A 2026 Assembly bill, AB 1559, would let homeowners request an in-person inspection.
Fox fixes the conditions the letter lists
Fox Roof Cleaning treats every roof slope for 3 growths, moss, algae and lichen, then clears the gutters in the same visit.
- Photograph the cited conditions from high angles
- Remove debris from valleys, crickets and skylights by hand
- Soft wash the full roof at low pressure
- Clean and flush gutters and downspouts
- Photograph the finished roof from the same angles
Every insurance job ends with a 4-part documentation package
Fox Roof Cleaning sends 4 items you can forward to your agent or upload to the carrier portal.
- Dated before-and-after photos, labeled by roof slope
- A work statement on Fox letterhead with address, date, method and scope
- A certificate of insurance with roof-specific liability coverage
- A written maintenance interval for your roof
Underwriters accept soft washing and question pressure washing
Fox Roof Cleaning uses only the low-pressure method that GAF and the Asphalt Roofing Manufacturers Association approve, never 1,500+ PSI.
Shingle makers prohibit pressure washing. Evidence of a pressure-washed roof can turn a cleaning citation into a warranty question.
Fox documents a clean roof even when the aerial image was wrong
Fox Roof Cleaning photographs a clean roof from at least 4 angles, so a mistaken citation can be disputed with dated proof.
Aerial images can be outdated or misread shade and tree cover. United Policyholders and the California Department of Insurance both accept complaints about aerial-image non-renewals.
