NIGP 91473: Roofing and Siding

NIGP 91473 Roofing and Siding, Item code, encompasses installation, repair, and replacement of roof assemblies and wall cladding systems across state and local facilities. Recent solicitations show state and local governments purchasing full roof replacements (membrane, metal panel, asphalt shingle systems), partial repairs and preventative maintenance contracts, gutter and downspout installation, flashing and trim work, and roofing material supply contracts—often bundled with siding or related envelope work. Issuing bodies span school districts (San Antonio ISD, Collin County Community College District, Columbia County School District, Alpine School District), county governments and special districts (Collier County, Kenosha County, St. Johns River Water Management District, Monroe County), state departments (California Department of Highway Patrol, Texas Historical Commission, Texas Department of Public Safety, Missouri Department of Transportation, Washington Military Department), city procurement offices (Tucson, Jackson, Madison, Boston, Pittsburgh, Westerville), and community colleges. Large systems and facility inventories drive sustained activity: Collier County manages roofing preventative maintenance across 351 county-owned facilities totaling 1.56 million square feet under a two-year contract with optional renewals; Hudson Valley Community College maintains four roofing system types across 39 buildings covering 769,594 square feet.

Geographic activity concentrates in Texas (multiple school districts, state agencies, and counties), California, Florida, Wisconsin, Washington, and Georgia, with scattered opportunities in Ohio, Arkansas, Massachusetts, New York, Pennsylvania, and Colorado. Representative recent solicitations include Collier County Board of County Commissioners requesting roofing preventative maintenance and repair services (RFP, proposals due August 10, 2026) estimated at $2.12 million historically; California Military Department requesting complete demolition and replacement of a 98,400 square-foot roof at Camp San Luis Obispo (IFB 26C875002, sealed bids due August 27, 2026) with mandatory pre-bid walk on July 23; St. Johns River Water Management District requesting metal roof, gutter, and downspout replacement at Pablo Creek Field Station (IFB ITB16389, bids due July 20, 2026, estimated budget $200,000); Missouri Department of Transportation requesting metal roof and siding installation on a state facility (IFB, bids due August 18, 2026) with mandatory pre-bid conference; and San Antonio ISD requesting continuous, open-ended general maintenance including roofing repairs and installations across district-wide facilities (RFP, proposals due August 15, 2026). Set-asides and preferences are common: prevailing wage requirements apply across state procurements; SBE, MBE, WBE, and DBE participation goals surface in California, Texas, and Florida solicitations; HUB subcontracting plans are mandatory in Texas for contracts exceeding $100,000; local-vendor preferences appear in Wisconsin and Colorado procurements. Bond requirements, insurance minimums ($1 million general liability standard), and manufacturer certifications are typical conditions.
