NIGP 77006: Aggregate, Gravel, Marble and Stone Chips, etc. (for Roofs)

NIGP 77006 Aggregate, Gravel, Marble And Stone Chips, Etc. (For Roofs), an Item code, captures the supply and delivery of roofing aggregate materials and related stone products that state and local governments procure for roof replacement, repair, and maintenance projects. Recent solicitations show municipalities and counties buying finished roofing stone (aggregate base course, rip-rap, gravel), TPO and asphalt membrane roofing systems with installed underlayment, and associated materials like flashings, insulation, and gutters as part of bundled roof replacement scopes. Cities, counties, and special-purpose districts issue the bulk of activity under this code—the City of Madison, City of Detroit, County of Santa Clara, Columbus Consolidated Government, Walker County, Bernalillo County, Boulder County Parks and Open Space Department, and the cities of Tybee Island and College Park all posted solicitations between March and July 2026. The issuing bodies span state capitals (Madison, Columbus), large metros (Detroit, San Jose area), rural counties (Walker County, Texas), and smaller municipal park and recreation departments (Tybee Island), indicating fragmented, geographically dispersed demand across multiple jurisdiction sizes and service types.

Recent activity concentrates in the Southeast and Midwest, with particular strength in Georgia, Wisconsin, Michigan, Florida, Texas, and Colorado. Representative recent solicitations include the City of Madison Engineering's RFB for Normal Hall Roof Replacement (due August 6, 2026), covering 3,600 square feet of asphalt shingle roof removal and replacement at a historic landmark with archaeological oversight requirements; the City of Detroit Office of Contracting and Procurement's RFQ 548310 for asphalt pick-up (Bituminous Aggregate Wearing Course 36A, 3,000 tons, due June 29, 2026); the County of Santa Clara's ITB-PRC-FY26-0588 for as-needed roofing repair services at multiple county facilities with prevailing-wage requirements (due July 7, 2026); Columbus Consolidated Government's RFB 26-0037 for stone on annual contract basis with two-vendor award structure and monthly usage around 200 tons (due June 17, 2026); and Bernalillo County's RFB 51-26-NM for gravel and landscaping materials including decorative rock, dirt, fill, and erosion control supplies with four-year pricing agreement and multi-tiered set-aside preferences up to 18 percent for state residents, Native American residents, veterans, and small businesses (due June 3, 2026). Pricing in the code typically flows through fixed unit rates per ton or per yard with all freight and delivery included, and contracts frequently establish blanket purchase agreements, annual supply arrangements, or emergency-response capabilities with 24-to-48-hour fulfillment windows.
