California Insurers Are Canceling Policies Over Dirty Roofs! We Can Help.
Across California, homeowners are receiving notices that their insurance policies are being canceled or not renewed — and in many cases, a dirty roof is the reason. Moss, algae, and biological growth are increasingly being classified as deferred maintenance, and insurers are acting on it. A professional cleaning and restoration performed by a licensed contractor — properly documented — is often all it takes to resolve the situation and retain your policy.
Pacific Exterior has helped hundreds of California homeowners resolve exactly this situation. We understand what insurers require — proper documentation, before-and-after evidence, and the high-definition aerial photography we routinely provide to substantiate our work. We handle all of it.
Since 2010, every homeowner who has hired us for this purpose has successfully maintained their policy. Not one exception.

Your Roof Is One of the Largest Investments on Your Property. We Treat It That Way.
Pacific Exterior was founded in 2010 on a straightforward conviction: the wrong cleaning method causes more damage to a roof or exterior surface than leaving it dirty ever would.
High-pressure washing strips granules from shingles, forces water under tiles, voids manufacturer warranties, and accelerates the very deterioration you’re trying to prevent. Our Safe Wash process uses carefully formulated, manufacturer-approved cleaning solutions applied at low pressure — eliminating algae, moss, lichen, and biological growth at the source, not just the surface. Simply put, it’s a non-pressure, detergent-based restoration — not pressure washing. The results last significantly longer, and your roof is never put at risk in the process.
This is the method we pioneered in Northern California. It’s the only method we use. And after more than 15 years and hundreds of documented jobs across the Bay Area and Monterey Bay, the results speak for themselves.
The Credentials, Experience, and Accountability
You Should Expect From Any Contractor
Before hiring anyone to work on your roof or exterior, every property owner deserves to ask a few straightforward questions. Here is where Pacific Exterior stands on each one.
Are you a licensed contractor?
Under California law, any exterior cleaning project valued over $1,000 requires a licensed contractor. Pacific Exterior holds a California B-General Contractor license — verifiable at any time through the CSLB — and has carried it since 2001.
What do your customers say?
Hundreds of five-star ratings across Google, Yelp, BBB, and Yahoo — from homeowners, commercial property managers, real estate professionals, and public figures throughout the Bay Area. Every one of them earned, never purchased. We’ll let them tell you in their own words below.
How long have you been doing this — and can you prove it?
We have been in continuous operation since 2010, with a documented job history spanning Santa Cruz, Monterey, Santa Clara, and San Mateo Counties. Our work map covers the full region — from residential neighborhoods in our Santa Cruz home base to high-value estates and commercial facilities throughout the Peninsula. We don’t just describe our experience; we can show it to you.
Are you properly insured?
Standard general liability policies do not cover roof-based work. Pacific Exterior carries specialized liability insurance specifically required for professional roof cleaning, along with full workers’ compensation coverage for every member of our crew — and we’ve carried both since we opened. This protects your property and protects you as the property owner if anything unexpected occurs on the job.
Have others in the industry recognized your work?
Pacific Exterior holds Diamond Certified status — earned through rigorous independent research and verified customer interviews. Our discovery and documentation of bacterial structure striping, a biological growth pattern affecting both building exteriors and roofs, was published in BUILDINGS Magazine. We were also featured in Concrete Decor Magazine, America’s leading publication in decorative concrete, for our approach to modern hard surface cleaning and restoration. We have maintained a BBB A+ rating for nearly 15 consecutive years.
