Professional roof cleaning in Gilroy, CA — serving downtown Gilroy, Eagle Ridge, Hecker Pass, and surrounding neighborhoods. Fast quotes, all 5-star reviews, fully insured.
With Gilroy's warm summers and wet winters, organic buildup on gutters and roofs accumulates fast. We know the local conditions and tree coverage better than anyone.
California's insurance crisis has made roof condition a make-or-break factor for homeowners. Insurers are canceling policies over moss, algae, and black streak buildup — signs they interpret as neglect. A dirty roof isn't just cosmetic: mold breaks down shingles from inside, traps moisture, and can void your roofing warranty.
ORS Clean uses a professional soft-wash method — biodegradable, low-pressure treatment that kills moss, algae, and lichen at the root without lifting or cracking shingles. We provide before-and-after photos suitable for insurance documentation. This is the method recommended by roofing manufacturers and insurance carriers.
Bay Area roofs typically need cleaning every 2–3 years. Homes with heavy shade, nearby trees, or coastal proximity accumulate mold faster and may need annual treatment. If you see black streaks or green patches, don't wait — it spreads.

"Matt was timely with his response, fair with his quote and professional with his work. I had my insurance company tell me I needed to clean the moss off the roof over the garage. I called ORS and Matt gave me a fair quote and did a good job cleaning the roof. He provided the pictures and invoice for proof for me to submit to insurance."
"I received a letter from my home owners insurance that I was being canceled due to moss and algae on my roof. Matt was great to work with. He came out the next day to site walk it and determine pricing. I received a quote that evening, and we were scheduled within 3 days. Matt and his crew showed up as scheduled, cleaned my roof and cleaned my solar panels. Matt sent me photos of the cleaned roof to submit to my insurance company. I highly recommend Matt and his crew."
