What is Pipe Boot?
Roofing Glossary · Roof Anatomy
Definition
A prefabricated rubber or metal flashing collar that seals around plumbing vent pipes where they penetrate through the roof surface. Pipe boots are installed over the pipe and under adjacent shingles, with the base nailed to the deck. The rubber collar compresses against the pipe for a watertight seal. Rubber boots eventually crack with UV exposure and are a common leak point on older roofs.
