What's happening in California?
California's property insurance market has undergone significant changes in recent years as insurers reassess wildfire exposure, property condition and other risks.
Roof condition can be one of the visible characteristics reviewed when an insurance company evaluates a property.
Heavy moss, algae, lichen, leaves and organic debris can make a roof appear poorly maintained and may contribute to moisture retention and deterioration over time.
For some homeowners, this results in a simple request:
Clean the roof and provide proof that the work was completed.

Why Insurers Care About Your Roof
Your Roof Is One of Your Home's Most Important Protective Systems

Moss
Moss can retain moisture against the roof surface and grow between roofing materials.

Algae
Algae and biological staining can create extensive discoloration and make a roof appear older or poorly maintained.

Lichen
Lichen attaches strongly to roofing surfaces and can become increasingly difficult to remove as it matures.
