NIGP 770: Roofing Materials and Supplies

NIGP 770 Roofing Materials and Supplies is a Class code under which state and local governments procure removal and replacement of roofing systems, roof repair and waterproofing services, roofing supplies and materials inventories, and specialized roofing work ranging from built-up asphalt and thermoplastic membranes to cedar shake and metal panels. School districts, municipalities, counties, community colleges, water agencies, fire districts, and state departments all solicit under this code, with roofing contractors competing for replacement projects across educational, administrative, recreational, and operational facilities. Recent solicitations show consistent demand across the Midwest and Southeast, with substantial activity in Michigan, Florida, Oregon, and Texas driven by aging building stock and capital improvement initiatives.

School districts represent the most active issuing bodies, with Taylor School District (Michigan) posting four major roof replacement RFBs alone between mid-September and mid-October 2026, each with response dates in late October and early November. These include roof replacements at the Board of Education building, Career Centers, and Wareing Elementary, typically specifying Tremco products as the basis of design, 20-year manufacturer warranties with inspections in years 2, 5, 10, and 15, and local preferential scoring of 3 percent for Taylor-based vendors. Mason Consolidated Schools (Michigan) and L'Anse Creuse Public Schools (Michigan) also posted high-value roof replacement bids in September and October 2026. Beyond schools, municipalities and special districts are regular buyers: the City of Taylor Heritage Park Pavilion (Michigan) solicited EPDM roof replacement in September 2026; San Jacinto College District (Texas) sought modified-bitumen roof restoration and envelope repairs with response due November 3, 2026; the City of Salem (Oregon) requested Navigation Center exterior improvements including roof replacement with bids due August 11, 2026; and the Oregon Department of Transportation posted two separate roof-replacement ITBs in August and September 2026 for maintenance facilities. County governments, water districts, fire protection districts, and housing authorities complete the mix, with recent activity including Santa Clara County Central Fire Protection District (California), Pasco County (Florida), Clackamas County Housing Authority (Oregon), and West Basin Municipal Water District (California). Geographic concentration is strongest in Michigan—home to at least six major school district roofing solicitations in the past two months—followed by Florida, Oregon, and Texas, with lower but steady activity across Arizona, Connecticut, Illinois, and Kentucky. Built-up asphalt and thermoplastic single-ply membranes dominate specifications, with metal panels and asphalt shingles common for smaller or specialized applications. Bid security, performance bonds, and labor/materials payment bonds typically apply to awards exceeding $50,000, and prevailing wage requirements appear consistently in Oregon and California public works projects. Contractors pursuing this code benefit from early intelligence on school district capital cycles (which often cluster in summer months) and from close attention to manufacturer basis-of-design language, which signals product-line advantage and technical support requirements that inform cost competitiveness.
