A roof vent pipe is a plumbing ventilation pipe that extends through the roof to release sewer gases and regulate air pressure in the plumbing system. It is typically sealed with a pipe boot or flashing to prevent water leaks. In roofing systems, proper sealing around vent pipes is critical to maintaining waterproof integrity. In rainy environments like Vancouver, roof vent pipes must be carefully flashed and maintained to prevent leaks and structural damage.
