The roof over your family is not a place to cut corners.
California First Roofing was built to be different. Licensed, bonded, and insured (CSLB #1094851), with 20+ years and 1,000+ roofs across California — premium GAF, Owens Corning, and Boral materials, warranties up to 50 years, and a written scope with fixed, transparent pricing.
Who we are
A South Bay roofing company, run by roofers.
We work out of 690 Saratoga Ave Ste 100 in San Jose and cover every community in Santa Clara County — Willow Glen, Almaden Valley, Naglee Park, Los Gatos, Saratoga, Cupertino, Morgan Hill, and beyond. Our estimators climb roofs. Our project managers answer their phones. And when the honest answer is "you don't need a new roof yet," that's the answer you'll get.
Fixed, transparent pricing
A written line-item scope before a single shingle moves. The number you sign is the number you pay.
Factory-certified crews
GAF Master Elite, Owens Corning Preferred, CertainTeed SELECT ShingleMaster, Polyglass Certified Applicator.
Never subcontracted
Our own vetted crews on every San Jose roof — the same faces from tear-off to final walk-through.
