Expert Verdict — Reviewed by the SuperArbor Pro Desk

Pick the ribbed style for extra rigidity on long or steep valleys, and open hemmed where the roof system calls for it. Always run valley flashing under the roofing with laps in the direction of water flow and center the W or V of the flashing on the valley line. Zincalume mill finish is a good match for unpainted metal roof panels.

Metal flashing edges are sharp; wear cut-resistant gloves and eye protection when handling, and work safely on roof slopes.
