Expert Verdict — Reviewed by the SuperArbor Pro Desk
Order the top and base together so diameters and finish match. The 4 in. round top suits standard vent stack penetrations. Do not rely on the cap alone for water control; the base must be properly lapped into the shingle courses.
Aluminum flashing edges can be sharp; wear gloves and handle carefully on the roof.
