1 · Product approvals

Product approvals

Alaska has no state product approval or listing system for roofing. Where a city enforces a building code, inspectors rely on the IRC's labeling rules and evaluation reports (ICC-ES, UL, etc.).

Code evaluation reports (ICC-ES, UL, IAPMO): 48 roofing reports
