What Bigham Taylor Roofing does

Bigham Taylor Roofing Corp. (BT Roof) is a privately held, commercial and industrial roofing contractor founded in 1977 by Steve Bigham and Don Taylor, headquartered in Hayward, California with a secondary operations office in Manteca. The company installs, replaces, restores, and maintains roof systems across Northern and Central California and Northern Nevada, holding California Class C-39, California Class B, Nevada Class C-15, and Asbestos Abatement licenses, with surety bonding via Merchants Bonding Co. Service scope spans emergency repair, preventative maintenance, roof restoration and coatings, seismic retrofit, structural work, and tenant improvements, delivered across roofing system types including TPO, PVC, EPDM, modified bitumen, built-up, KEE/FiberTite, metal, and torch-applied membranes. Execution technology includes up to five robotic membrane welders, Rhinobond induction welding, CleanWrap interior dust/debris protection, and tapered cricket drainage systems supporting projects up to 800,000+ sq ft with documented 20-year, 100-mph-wind-rated warranties.

Revenue is generated through project-based commercial roofing contracts (one-time, scope-defined engagements) supplemented by recurring preventative maintenance subscriptions, all priced through custom quotes. Go-to-market is enterprise field sales: BT Roof is selected by property owners, facility managers, consultants, and general contractors via RFPs, consultant specifications, and repeat-bid inclusion, supported by a client portal and an inbound website estimate request flow. Master Certified status with Johns Manville, Elevate (Holcim), and Carlisle SynTec Systems, plus the Carlisle Hall of Fame 500 award, function as the primary supplier ecosystem and warranty gateway. Operations serve enterprise customers across healthcare (Sutter Health, St. Joseph's, Fresenius, Abbott), technology (Fujifilm, Fujitsu, MiTAC), industrial/logistics (Miller International, Prologis, Vestar), retail/REIT (Utah Retirement System, Vestar), and senior living (Sunrise). Customer concentration appears diversified across named enterprise logos, but project-based pricing with multi-year warranty continuity creates anchor-account stickiness that materially reduces churn on key relationships.
