Expert Verdict Reviewed by the SuperArbor Pro Desk

W-valley flashing in 26 ga galvanized steel is a workhorse choice for asphalt shingle valleys, helping water track down the center rib rather than along the shingle cut edges. Lap pieces adequately and keep laps consistent with the valley direction. In coastal or high-corrosion environments, consider whether a heavier gauge or alternative coating suits the job.

Galvanized flashing edges can be sharp; wear gloves and use fall protection when working on roofs.
