NIGP 77023: Cements and Mastics, Roofing

NIGP 77023 Cements and Mastics, Roofing, Item code, encompasses the products and materials state and local governments procure to restore, seal, and waterproof existing roof membranes—primarily silicone and polyurethane coatings, cold-applied synthetic rubber restoration systems, thermoplastic polyolefin (TPO) membranes, and fluid-applied waterproofing systems applied to metal and modified-bitumen substrates. Recent solicitations show this code driving activity across community college districts, county facilities, municipal transit and fire protection departments, and city parks infrastructure, with issuing bodies including San Jacinto College District, the City of Rome Georgia Transit Department, Okaloosa County Florida, Santa Clara County California, and Jackson County Missouri. Work centers on mid-scale roof refurbishment projects—typically 2,600 to 50,000 square feet per project—in which contractors apply protective membrane coatings, conduct surface preparation, and execute envelope repairs to extend roof life without full replacement.

Recent opportunities are concentrated in Texas, Georgia, California, and Arizona, with scattered activity in Wisconsin, Kentucky, and Florida. Representative solicitations include San Jacinto College District's CSP #27-04 Building N1 Roof and Envelope Repairs (competitive sealed proposal, responses due November 3, 2026) for approximately 50,000 square feet of modified-bitumen roofing restoration with silicone coating; Okaloosa County Florida's ITB FM 64-26 Rigdon Center Roof Restoration and Repairs (sealed bids, due July 15, 2026) for 21,800 square feet of fluid-applied polyurethane and cold-applied synthetic rubber coatings across three metal roof sections; and Jackson County Missouri's ITB 26-037 County-Wide Roofing Services (bids due June 16, 2026) for an estimated annual spend of approximately $330,000 on time-and-materials roofing work across all roof types, with an established 9.5 percent minority-owned business participation goal. Municipal and county procurement offices are managing these bids through both sealed-proposal and ITB processes; prevailing wage compliance is required on public-works projects in California jurisdictions. Pre-bid meetings and site visits are standard, with question deadlines typically ten to fourteen days before bid submission.
