NIGP 77073: Roofing, Tin

NIGP 77073 Roofing, Tin, an Item code, encompasses roofing supplies, materials, and replacement systems that state and local governments buy through indefinite-quantity cataloging contracts, fixed-price roof replacement projects, and on-call emergency repair services across municipal facilities, school districts, county buildings, and transit authorities. Recent solicitations show governments procuring both stocked and special-order roofing components (membranes, flashings, underlayment, gutters, downspouts, insulation board, fasteners) through blanket supply agreements, as well as full-scope installation services including removal, surface preparation, waterproofing application, and warranty obligations on asphalt shingle, TPO (thermoplastic polyolefin), modified bitumen, EPDM, metal, and built-up roofing systems. Work ranges from routine maintenance and emergency leak response on district-wide facilities to large design-build replacement projects on convention centers and airport terminals.

Activity under this code spans municipal procurement offices, county departments, school districts, and special-purpose authorities in at least twelve states, with notable recent concentration in Florida (Volusia County, Okaloosa County, Hillsborough County Public Schools, City of Tybee Island, City of College Park), Georgia (DeKalb County School District, City of Colquitt), and California (County of Santa Clara). Representative recent opportunities include the City of Tucson issuing an indefinite-quantity RFQ for roofing supplies and special-order materials due July 29, 2026; the City of Madison issuing an RFB for a 3,600 square-foot asphalt shingle roof replacement on Normal Hall due August 6, 2026 with a mandatory pre-bid site visit July 22, 2026; the County of Santa Clara issuing an ITB for as-needed roofing repair services countywide under prevailing wage due July 7, 2026; Okaloosa County issuing an ITB for fluid-applied waterproofing membrane restoration on approximately 21,800 square feet of metal roof at the Rigdon Center due July 15, 2026; Jackson County, Missouri issuing an ITB for county-wide roofing services on a 24-month term with time-and-materials pricing and a 9.5 percent MBE participation goal, with estimated annual spending of approximately $330,000; and the Greater Orlando Aviation Authority conducting a design-build procurement (BP-00511) for North Terminal Roof Replacement covering approximately 334,725 square feet across Areas 2-6, with a $13,000,000 estimated project budget and substantial completion timeline of 640 calendar days.
