Your Insurance Policy May Depend on It

Insurance companies across California are increasingly canceling or refusing to renew homeowner policies due to roof condition — specifically the presence of moss, algae, and biological growth that insurers classify as deferred maintenance. If your insurer has flagged your roof, or if you want to make sure they never do, the right response is a professional cleaning performed by a licensed contractor — documented properly and done safely.

The Right Way to Clean and Restore Exterior Building Surfaces

Most of what grows on a roof — the dark streaking across north-facing facets, the green patches in shaded areas, the biological staining that builds up over years — isn’t just surface dirt. Algae, bacteria, lichen, moss, and fungus root into roofing and exterior materials and cause ongoing deterioration that worsens over time.

Pressure Washing Damage

Pressure washing may remove most of what you can see. It does nothing about what’s causing it — and on tile, slate, asphalt shingle, and most other roofing and exterior materials, high pressure causes physical damage that voids manufacturer warranties and shortens the life of the surface.

Safe Wash

Our Safe Wash process uses low-pressure application with custom-blended cleaning solutions that eliminate biological growth at the source. Results are immediate and lasting (we guarantee it). It’s the method recommended by GAF, Sto, Dryvit, and most major roofing and exterior product manufacturers — and it’s the only method we use. Simply put, it’s a non-pressure, detergent-based restoration — not pressure washing.

Why Homeowners and Property Managers in
Santa Clara County Choose Pacific Exterior

Every property owner deserves to know who they’re hiring. Before signing with any contractor for roof or exterior cleaning, it’s worth asking for their contractor’s license number, proof of roof-specific liability insurance, and workers’ comp documentation. We’re happy to provide all of it, along with documented proof of work and extensive before-and-after photography from jobs throughout the region.

License

State law requires a contractor’s license for any exterior cleaning job valued over $1,000 — ours is verifiable through the CSLB and we’ve carried it since 2001.

5.0 Star Rating

Hundreds of verified reviews across Google, Yelp, BBB, and Yahoo — every one of them earned, never purchased.

About Pacific Exterior

Pacific Exterior was founded in 2010 by a California-licensed contractor with over 25 years of field experience. We are the original soft-wash contractor in Northern California — operating and documented since the day we opened.

This is our craft, and that focus shows in our results, our equipment, our insurance coverage, and our track record. From single-family homes to complex commercial facilities and HOA communities, we bring the same licensed, insured, and documented approach to every job.

Our crews serve Santa Clara County regularly and will travel for larger commercial and estate-level projects throughout the Bay Area.
