Expert Verdict — Reviewed by the SuperArbor Pro Desk
For copper roofs or premium slate and shake jobs, 16 oz copper W-valley is the standard choice and should not be combined with dissimilar metals that cause galvanic corrosion. Overlap pieces at least the manufacturer's recommended lap and nail only at the edges outside the water channel. Widen to 24 in. on long or high-volume valleys.
Copper flashing edges can be sharp; wear cut-resistant gloves and use roof anchors when working on slopes.
Order Berger Copper W-Valley flashing in 18 in. or 24 in. widths for durable valley protection.
