Bishop

What Bishop does

Bishop, Inc. is a privately held commercial roofing, waterproofing, and sheet metal contractor headquartered in Orange, California, with a secondary office in National City (San Diego). Founded in 1998 and operating for over 20 years, the company self-performs roofing systems (asphalt shingles, green roofs, clay and concrete tile, single-ply, modified bitumen, coatings, interior protection), commercial waterproofing, and metal roofing and panel fabrication using in-house crews rather than subcontractors. The firm holds California Contractor's License #793917 (B, C-39, C-43, C-12) and is certified as a DBE, MBE, SBE, and SCMBDC, positioning it as a prime contractor on federal set-aside work.

Revenue is generated through project-based engagements, primarily IDIQ contracts and individual task orders with federal and military clients including the GSA, US Army, US Navy, FBI, USPS, Department of Veterans Affairs, and FDIC, supplemented by work for educational institutions (Cal State Fullerton), healthcare facilities (Naval Hospital Camp Pendleton, St. Jude Medical Center), and commercial property managers (South Coast Plaza, Knott's Berry Farm, Bank of America). Operational reach extends across California, Nevada, and Arizona, with demonstrated capability to manage up to 20 simultaneous projects at geographically dispersed sites. Pricing is quote-based and undisclosed, and the firm explicitly avoids commission-driven sales in favor of need-based evaluations.

The company's competitive positioning rests on its federal certifications, a documented zero OSHA injury record and 0.73 EMR safety profile, over 100 years of combined experience among key personnel, and a diversified multi-vendor material sourcing strategy across major roofing manufacturers. With a headcount of 11–50 employees and no disclosed funding, M&A activity, or leadership changes, Bishop operates as a stable, independently owned specialty contractor focused on safety, self-performance, and federal procurement credentials.

Direct peers

• Nations Roof: Nations Roof is a national commercial roofing contractor providing roof system installation, maintenance, and replacement for industrial, retail, and institutional clients. Its project-based, self-perform delivery for non-residential customers closely mirrors Bishop's GTM.
• CentiMark Corporation: CentiMark is one of the largest U.S. commercial roofing contractors, providing roof installation, repair, and maintenance for non-residential buildings across multiple states. It is the closest large-scale direct competitor to Bishop's commercial roofing and waterproofing service line.
• Flynn Group of Companies: Flynn Group operates a North American roofing and building-envelope contracting business serving commercial and institutional clients. Its combined roofing, waterproofing, and sheet metal offering delivered through regional branches parallels Bishop's three-trade integrated service model.
• Tecta America: Tecta America is a national commercial roofing contractor with regional operating companies serving institutional, industrial, and government clients. Its multi-region, self-perform model and federal contracting exposure make it a direct comparable to Bishop.
• Bone Dry Roofing: Bone Dry is a multi-state commercial and residential roofing contractor with regional offices across the Midwest and Southeast. It is a comparable regional self-perform roofing operator, though Bishop leans more heavily on federal/government work.
• Greenwood Industries: Greenwood Industries is a commercial roofing, sheet metal, and waterproofing contractor serving industrial, institutional, and government clients nationwide. Its bundled roofing-plus-waterproofing service line and federal exposure match Bishop's integrated offering.
• Baker Roofing Company: Baker Roofing is a multi-state Southeastern commercial and residential roofing contractor offering installation, repair, and sheet metal services. Its regional scale and similar mixed commercial/government service mix mirror Bishop's operating model.

Broad incumbents

• Duro-Last Roofing: Duro-Last is a national manufacturer and installer of custom-fabricated single-ply roofing systems serving commercial clients. While Bishop sources Duro-Last membranes, Duro-Last also competes as a vertically integrated installer in the same commercial roofing category.
• Tremco Roofing & Building Maintenance: Tremco is a large commercial roofing and waterproofing contractor (also a major manufacturer) under RPM International. It overlaps with Bishop across commercial roofing and waterproofing but operates as part of a much broader materials-and-services portfolio.
• Roofing Corp of America: Roofing Corp of America is a multi-brand commercial roofing platform consolidating regional contractors nationally. It operates in the same space as Bishop but at meaningfully greater scale, serving as a broad incumbent and a potential roll-up acquirer of regional players like Bishop.
