Expert Verdict Reviewed by the SuperArbor Pro Desk

Install the flashing base lapped into the shingle courses below the penetration and let upper courses cover the top edge so water never runs against the flow into the cut. Dead soft aluminum is easy to dress, but avoid over-working any single spot, which can fatigue the metal. For high-heat flues rather than soil stacks, use a flashing rated for that temperature instead.

Aluminum flashing edges can be sharp; wear gloves when handling and dressing the metal on the roof.
