Expert Verdict — Reviewed by the SuperArbor Pro Desk
Size the flashing by pipe diameter, not by the base, so the EPDM collar snaps down tightly for the auto-caulk seal. Slide the base up under the upslope shingles and leave the downslope flange exposed so water runs over it, and it will handle pitches to 40 degrees. Pick copper or aluminum variants where appearance or corrosion compatibility with your roof metal matters.
Use caution on roofs above 30 degrees; this flashing fits up to 40 degree pitch but steeper roofs require added fall protection.
Order the brown 3 in. to 4 in. auto caulk pipe flashing for a leak-proof, no-caulk vent seal.
