Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 4 in. base suits smaller-diameter pipe penetrations where roof space is tight. Always match base and top diameters so the cap seats properly. Seal and lap the base per the manufacturer's instructions and local code.
Aluminum flashing edges can be sharp; wear gloves and handle carefully on the roof.
