Expert Verdict Reviewed by the SuperArbor Pro Desk

At 10 in. wide this flashing gives good lap onto the deck on both sides of the valley; for wide or high-flow valleys consider upgrading to a W- or T-formed valley or a heavier gauge. Crease the center before installing so the sheet can move with thermal expansion, and never nail through the valley center where water travels.

Metal flashing edges can cut; wear cut-resistant gloves and take fall-protection precautions when working in roof valleys.
