Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 3-in-1 design lets a crew stock one flashing for four common pipe sizes, reducing attic callbacks for wrong-size orders. Slide the base over the pipe before shingling and weave base shingles over the upslope flange per manufacturer instructions. For hotter type "B" flues beyond 45 degrees, stick to the 1-1/2 in. and 2 in. collar configurations.
Install per the manufacturer's instructions and local code; on steep or high roofs use appropriate fall protection while working around vent penetrations.
Stock the IPS 3-in-1 weathered grey pipe flashing and cover four vent sizes with one unit.
