Quick Answer: A full roof replacement in San Jose, California in 2025 costs $15,000-$40,000 for a typical 2,000 sq ft home, depending on roofing material, roof complexity (number of valleys, hips, dormers), and current roofing removal cost. Asphalt architectural shingles are the most affordable option at $8-$14 per sq ft installed (including tear-off and disposal). Concrete tile runs $12-$20/sq ft. Metal standing seam runs $18-$35/sq ft. Class A fire-rated roofing is required in most San Jose neighborhoods due to the California Fire Code — standard 3-tab asphalt shingles are generally not fire rated and should not be used without verification of your zone’s requirements.

Fire Rating Requirements in San Jose
Most San Jose neighborhoods require Class A fire-rated roofing under California Building Code Section R902. Class A is the highest fire rating — it means the roofing material resists fire penetration from an external source for at least 2 hours under the UL 790 test. Concrete tile, clay tile, and metal are inherently Class A. Asphalt shingles must be specifically labeled “Class A” — most architectural shingles from GAF, CertainTeed, and Owens Corning carry a Class A listing when installed over solid sheathing with a fire-rated underlayment.
