Received a Roof Cleaning Notice From Your Insurance Company?
We help Bay Area homeowners resolve insurance non-renewal notices with professional roof cleaning, full documentation, and before-and-after evidence your insurer requires.
Why Insurance Companies Are Canceling Policies Over Dirty Roofs
Insurance companies across California are using aerial drone imagery and satellite photography to inspect roofs -- without ever stepping foot on your property. What they're looking for: moss, algae, black streaks, lichen, and any visible biological growth.
Even if your roof is structurally sound, visible organic growth is now classified as deferred maintenance -- and insurers are acting on it. Homeowners are receiving non-renewal notices, policy cancellations, and premium increases based solely on what their roof looks like from above.
What Happens If You Ignore the Notice
If You Don't Act
- Policy gets canceled or non-renewed
- New insurance at 2-3x the premium (if you can get it)
- Property value drops -- buyers see uninsurable risk
- Organic growth causes actual roof damage over time
- Premature roof replacement: $15,000-$40,000+

Frequently Asked Questions
Will roof cleaning actually save my insurance policy?
In the vast majority of cases, yes. Insurance companies issue non-renewal notices to prompt action. Once you provide documentation showing the roof has been professionally cleaned and the organic growth removed, most insurers will reinstate or continue your policy. The key is acting quickly and providing proper documentation -- which we handle for you.
How long does the cleaning last?
Our soft wash treatment kills organic growth at the root, not just the surface. Results typically last 2-3 years, sometimes longer depending on your roof's sun exposure and surrounding trees. This gives you a long runway before your next cleaning.
Will pressure washing void my roof warranty?
High-pressure washing can void manufacturer warranties -- which is exactly why we DON'T use it. Our soft wash method uses low-pressure application that is safe for all roof types and compliant with every major shingle manufacturer's guidelines.
How much does insurance compliance roof cleaning cost?
Most residential roofs range from $800-$1,500 depending on size, pitch, and severity of growth. Compare that to $15,000-$40,000+ for a premature roof replacement, or 2-3x higher insurance premiums with a new carrier. Professional cleaning is by far the most cost-effective solution.
How quickly can you schedule the service?
We understand insurance notices have deadlines. We typically schedule insurance compliance cleanings within 3-5 business days of your call. Rush service is available if your deadline is sooner.
What if my insurer still cancels after cleaning?
This is extremely rare when proper documentation is provided. If for any reason your insurer doesn't accept our documentation, we'll work with you to provide any additional information they require at no extra charge.
