Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use the 3 in. x 3 in. galvanized profile where the edge detail calls for a taller gravel stop than standard 2 in. versions. Keep the galvanized surface intact at fastener penetrations and use compatible fasteners to limit corrosion at cut edges. Where the client wants a painted edge, prepare and prime the galvanized surface before topcoating.
Sheet-metal flashing edges are sharp; wear cut-resistant gloves and eye protection when handling and cutting.
Order the TRI-BUILT 28-gauge Galvanized Gravel Guard for corrosion-resistant roof-edge protection.
