What is the name of the flashing around a plumbing vent pipe?

The flashing around a plumbing vent pipe is called a boot. This component is specifically designed to provide a watertight seal between the pipe and the roofing material, preventing water from entering the building around the vent. Boots are typically made from durable materials like rubber or metal and are essential for ensuring the longevity and integrity of the roofing system. By fitting snugly around the vent pipe, the boot directs water away from the pipe and down the roof slope, enhancing protection against potential leaks.

The other terms refer to different roofing components: a pan typically refers to a type of flashing used at the bottom of a wall, apron flashing is placed at the intersection of a wall and a roof to direct water away, and gutters are systems installed along the eaves of the roof to collect and channel rainwater. Each of these plays a critical role in managing water on the roof but does not serve the same specific function as a boot.
