UNSPSC 30151510: Slate roofing

UNSPSC 30151510 Slate roofing is a Commodity code that captures a narrow slice of actual state and local procurement activity — primarily commercial and institutional roof repair and replacement work across multiple membrane and material systems, though the recent opportunities show almost no demand specifically for slate roofing. State and local governments issue these solicitations through cities, counties, school districts, and special districts for maintenance and replacement of existing roofs on public buildings, libraries, recreation centers, administrative facilities, and educational campuses. The work typically includes removal of existing roofing systems (asphalt shingle, modified bitumen, TPO, metal, or tile), substrate repair, installation of new membrane or shingle systems with associated flashing and drainage, and performance warranties ranging from five to twenty years. Issuing bodies vary by jurisdiction type — Florida counties (Monroe, Volusia, Orange, Clay) and cities (Tallahassee, Tybee Island, Tucson, Madison) dominate the recent opportunity set, alongside school districts (DeKalb County, Lone Star College) and special districts in Georgia. Contractors must hold state-specific roofing or general contractor licenses (Florida, Georgia, California, Wisconsin), maintain commercial general liability insurance of $1 million to $2 million per occurrence, and comply with prevailing-wage and federal procurement rules where federal funding applies. Many jurisdictions require pre-bid or pre-proposal site visits, 10 percent bid bonds, and performance bonds equal to 100 percent of contract value upon award.

Representative recent opportunities include the City of Madison Engineering's Normal Hall Roof Replacement (RFB, bids due August 6, 2026) covering approximately 3,600 square feet of asphalt shingle removal and replacement on a historic park pavilion, with compliance requirements for Wisconsin burial site preservation statutes and a one-year warranty; Monroe County's Key West Library Roof Replacement (RFP, proposals due July 28, 2026) for removal of concrete tile roofing and installation of V-Crimp metal roofing in strict accordance with Miami Dade Notices of Acceptance, covering 15,400 square feet; the City of Tucson's Roofing Supplies procurement (RFB, bids due July 29, 2026) for an indefinite-quantity catalog of stocked and special-order roofing materials subject to ARPA compliance; and the DeKalb County School District's District Wide Roofing Repairs and Emergency Services (ITB, bids due May 7, 2026) covering emergency leak response across 139 schools and facilities on multiple roofing types with mandatory 4-hour response times. Recent activity concentrates in Florida and Georgia, with secondary activity in California, Wisconsin, and Texas. The code sees continuous activity but reflects actual procurement in roof repair and replacement of common commercial systems rather than slate-specific work; firms without expertise in slate installation may find alignment marginal.
