UNSPSC 30151603: Gravel stops

UNSPSC 30151603 Gravel stops (Commodity) covers roof-edge and perimeter materials — specifically gravel guards, ridge rolls, and edge strips — that state and local governments procure as components of larger roofing projects. Recent opportunities show this code being tagged to roof repair, replacement, and maintenance work where gravel stops function as protective trim pieces rather than as standalone material orders. The code sees solicitation from municipalities, counties, special-purpose fire districts, school districts, and state health agencies, typically embedded within facility maintenance or capital improvement programs rather than as discrete commodity procurements.

Activity is concentrated in Texas and California. Representative recent opportunities include the Texas Health and Human Services Commission (HHSC) Invitation for Bids (IFB) HHS0017204 (posted June 16, 2026, due June 3, 2026) for roof repairs at the San Antonio Texas Center for Infectious Disease facility covering approximately 24,485 square feet and explicitly citing gravel guards under NIGP code 770-41, with ESBD set-asides and VetHUB subcontracting plan requirements; Houston Independent School District RFP 270002 (posted June 29, 2026, due July 30, 2026) for roofing repairs and improvements at McCollum and Harlandale High Schools requiring 20-year system lifespan with completion by December 31, 2026; Santa Clara County Central Fire Protection District ITB ITBCFDFY270065 (posted August 12, 2026, due September 9, 2026) for roof replacement at San Martin, California with mandatory pre-bid site visit August 24, 2026 and prevailing wage requirements; and City of Rome, Georgia Bid 037-26 (posted October 5, 2026, due October 29, 2026) for transit department roof coating. The code shows minimal standalone procurement volume — gravel stops typically appear as line items within larger roofing packages rather than as primary solicitation drivers.
