Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use step flashing, not continuous flashing, at dormers and chimneys so each shingle course is independently sealed; this aluminum piece is sized for exactly that detail. Match black or brown to the shingle or trim color for a discreet appearance. The 2 in. x 3 in. brown size suits tighter reveals, while 2-5/8 in. x 3 in. gives more up-wall coverage behind siding or trim.
Aluminum flashing edges can be sharp; wear gloves when handling and follow ladder and roof fall-safety practices during installation.
Order Berger Aluminum Dormer Flashing in black or brown to seal dormers and chimneys right.
