Why San Mateo County Homeowners Choose R&J Roofing
When a roof fails, homeowners across the Peninsula call R&J Roofing because we've been here since 2002 and we're not going anywhere. We're not a franchise, not a door-to-door outfit, and not a company that subs everything out. Randy and the crew do the work themselves, show up when they say they will, and price jobs honestly.
We carry CA Contractor's License #807358, we're fully bonded and insured, and we pull permits on every job that requires one. We work on composition shingles, architectural shingles, concrete tile, clay tile, and slate — residential and commercial, new installs and repairs.
Our service area covers San Mateo County and the cities of San Mateo, Redwood City, Menlo Park, Palo Alto, Mountain View, and Sunnyvale in Santa Clara County. We do not serve areas north of San Francisco or east of the Dumbarton Bridge.
