Expert Verdict — Reviewed by the SuperArbor Pro Desk
Size the vent to the pipe so the collar slips over the penetration without forcing. Bed the flanged base in sealant and fasten through the flange into solid sheathing, then shingle up-slope over the flange. The Acrylume mill finish blends with bare Galvalume panels; choose a painted color for metal roofs with a baked-on finish.
Work safely on pitched roofs with fall protection, and caulk the flange fully to prevent water entry at the penetration.
