NIGP 77045: Insulation, Roof, All Kinds

NIGP 77045 Insulation, Roof, All Kinds is an Item code encompassing removal and replacement of existing roofing systems, installation of insulation boards and membranes, flashing work, and related labor on municipal buildings, higher-education facilities, county infrastructure, and special-purpose districts. State and local governments soliciting under this code are currently procuring complete roof replacements using specified membrane systems—single-ply TPO, EPDM, PVC, and specialty materials such as cedar shake shingles and slate tile—with manufacturer certification requirements, extended warranties, and performance bonding. Issuing bodies include city procurement offices (Detroit, Tucson, Phoenix, Doral, Tybee Island, Madison, Tarpon Springs, Taylor, Conyers, College Park), county governments (Harris County, Chatham County, Jackson County, Pasco County, Santa Clara County, Stephens County Board of Education, Kane County Forest Preserve District), community colleges (Houston City College, City Colleges of Chicago, San Jacinto College), fire districts (Santa Clara County Central Fire Protection District, Louisville Fire Department), and transit or special-purpose authorities. Detroit's Construction and Demolition Department appears twice with Duro-Last roof systems; Chatham County and Houston City College each issued multiple related solicitations in the May-June 2026 window.

Recent opportunities span Michigan, Georgia, Texas, Florida, California, Illinois, and Mississippi, with particular density in the South and Midwest. Representative recent solicitations include the City of Detroit Office of Contracting and Procurement requesting proposals for Duro-Last Roof System installation at the 3rd Precinct (RFP, proposals due October 16, 2026, with 15-year warranty and 10-point minimum contractor experience requirement); City of Taylor, Michigan soliciting sealed bids for Taylor Heritage Park Pavilion Roof Project under IFB9212622 (bids due October 12, 2026, requiring factory-trained Carlisle SynTec authorization or written pre-qualification, 20-year total system warranty, mandatory pre-bid inspection); Harris County Precinct 2 requesting bids on TPO roofing replacement at the Leonel J. Castillo Community Center under ITB 26/0102 (bids due June 15, 2026, with M/WBE participation goals, five-year workmanship warranty, 20-year No Dollar Limit manufacturer warranty, prevailing wage compliance); and Chatham County, Georgia soliciting bids for 60 mil TPO membrane installation at the Records Center (bids due June 18, 2026, with 30 percent combined M/WBE participation goal, manufacturer-restricted to GAF, Firestone, or John Mannville). Bid bonds typically range from 5 to 10 percent; performance and payment bonds equal 100 percent of contract value. Most municipal roofing contracts run one to two years with optional renewals; liquidated damages for delay range from $500 to $2,500 per calendar day. Prevailing wage and OSHA compliance (10/30 certification) are common on public works. Set-asides and M/WBE participation goals appear regularly in Texas and Georgia solicitations but vary by jurisdiction.
