Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pitch-matched flanges sit flatter against the deck and shed water better than a one-size flange, so always order the 5/12, 8/12, or 10/12 version that matches the roof. Bed the flange in roofing sealant and fasten per shingle manufacturer practice, integrating it into the shingle courses uphill of the vent. Keep the mill finish and pair with a matching Joval wind band cap where wind-driven rain is a concern.
Check local plumbing and roofing codes for vent flashing requirements before installation, and use fall protection when working on a roof.
Order the Joval Roof Flange in your pipe size and roof pitch for a weather-tight plumbing vent.
