NIGP 70058: Proofing Systems

NIGP 70058 Proofing Systems, an Item code, encompasses roof replacement and repair work on municipal facilities, including removal of existing roofing materials, installation of new asphalt shingles or comparable systems, replacement of damaged roof sheathing, and associated ancillary work such as gutter and flashing reinstallation. State and local governments solicit roofing services primarily through cities and municipalities for public buildings and park facilities; the recent activity reflects municipal engineering departments managing capital maintenance on aging structures. The work typically involves fixed-price competitive bidding under IFB or RFQ structures, with mandatory pre-bid site visits, detailed specification compliance including local and state building code adherence, and performance guarantees spanning one or more years post-completion.

The City of Madison, Wisconsin posted a representative recent solicitation in July 2026 (RFB# 15026-0-2026, due August 14, 2026) for roof replacement on Normal Hall, a 3,600-square-foot asphalt shingle roof replacement on a historic landmark pavilion originally installed in 2000. The scope included removal and replacement of roofing materials to sheathing, repair of damaged sheathing on the northern side, installation of new underlayment and asphalt shingles, replacement of counterflashing at clerestory windows, and reinstallation of gutters and downspouts. Work was scheduled to begin October 1, 2026 and complete by October 30, 2026, with a one-year performance guarantee required. The solicitation mandated compliance with Wisconsin Statute 157.70 regarding burial site preservation, commercial general liability insurance of at least $1,000,000 per occurrence, and local vendor preference scoring for contractors registered with the City of Madison as of the bid due date. The source supports no additional geographic or issuing-body data beyond this single recent Wisconsin opportunity.
