Roofing Contractor in San Mateo County

We serve Northern California across three regions: the San Francisco Bay Area, Greater Sacramento, and the Central Valley. Our published guides cover 14 counties and 88 cities. Our Castro Valley and Sacramento offices support local estimating, permit coordination, and project planning across these regions.

Financing may be available for eligible projects with approved credit. Available terms depend on lender approval, project scope, and current programs. Your project manager can review the options that apply before work begins. We also accept checks, ACH, and major credit cards.

San Mateo County spans coastal fog belt (Pacifica, Half Moon Bay) and inland valleys (Redwood City, San Carlos). Coastal homes face salt-air corrosion and persistent moisture, making material selection critical. The county has a mix of postwar ranch homes and modern builds, with hillside properties in Hillsborough and San Carlos subject to WUI fire zone requirements.

For Alameda County homes in Alameda County, we most often recommend asphalt architectural shingles for their balance of durability and value. Tile roofing is popular in neighborhoods like Oakland for its aesthetic appeal, and metal roofs are ideal for energy efficiency in the Bay Area climate.

Most roof replacements in Alameda County take 3-5 days depending on the size and complexity. We handle all permits required by Alameda County and keep your property clean throughout the process.

Many older homes in Alameda and Alameda County were built before modern seismic codes. While a roof replacement alone doesn't trigger a seismic retrofit requirement, it's the ideal time to reinforce roof-to-wall connections — especially for homes near the Hayward Fault. Hamilton Exteriors uses Simpson Strong-Tie hurricane clips on every roof we install, which improves earthquake resistance and meets California's latest building standards at no extra cost.

Yes. Parts of Alameda and the East Bay Hills fall within Cal Fire's Very High Fire Hazard Severity Zones (VHFHSZ). Homes in these zones must use Class A fire-rated roofing materials — which includes the asphalt, metal, and tile options Hamilton Exteriors installs. If your property is in a designated fire zone, we also ensure compliant ember-resistant vents and remove combustible material within 5 feet of the roofline as part of our standard installation process.
