Expert Verdict — Reviewed by the SuperArbor Pro Desk
Order the base and cap together so the assembly matches - this listing is the 4 in. shake base only in mill finish. Mill aluminum weathers naturally and suits exposed-metal or shake roofs where a painted finish is not needed. Verify pipe size against the 4 in. base diameter before ordering.
Metal flashing edges can be sharp; wear gloves when handling and installing.
