Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always order the storm collar to match the vent pipe diameter and the roof jack flashing already installed. Bed the collar in a continuous bead of silicone where it meets the pipe—this is the manufacturer's required seal. Galvanized mill finish suits standard B-vent assemblies; confirm the flashing base material matches the rest of the penetration for corrosion consistency.
Work on roofs only with proper fall protection, and apply sealant with adequate ventilation.
