Common types of Roof Vent Pipes
Plumbing Vent Pipes
These pipes are part of your home’s plumbing system. They vent ushers gases out of your home, preventing foul odors from backing up into your drains. They also allow fresh air into the plumbing system to maintain proper water flow and drainage.
- Materials: PVC, ABS plastic, or metal.
- Location: These typically protrude through the roof vertically and are connected to your home’s plumbing stack.
Furnace Vent Pipes
These vent pipes expel exhaust gases from your furnace or water heater, ensuring harmful gases like carbon monoxide don’t accumulate inside your home.
- Materials: Metal, such as aluminum or galvanized steel, due to their ability to withstand high temperatures.
- Special Features: Double-wall or insulated pipes are often used to prevent condensation.
Dryer Vent Pipes
These pipes allow hot, moist air and lint from your dryer to exit your home. Proper venting prevents fire hazards and helps your dryer operate efficiently.
- Materials: Flexible aluminum or rigid metal ductwork.
- Considerations: Dryer vent pipes need regular cleaning to avoid lint build-up.
Gas Appliance Vent Pipes
Vent pipes connected to appliances like gas fireplaces or stoves carry exhaust gases, such as carbon monoxide, outside your home.
- Materials: Stainless steel or aluminum, with variations depending on the appliance’s heat output.
- Special Requirements: Some use a “direct vent” system, which includes two pipes—one for exhaust and one for intake air.
Ventilation Pipes (Attic and Roof Ventilation)
These pipes are part of your home’s roof ventilation system, helping to regulate attic temperature and moisture. They prevent mold growth, ice dams, and premature roofing wear.
- Materials: Typically metal or high-quality plastic.

Other Helpful Information To Know About A Plumbing Vent Pipe Leak
Unfortunately, the flashing designed for your plumbing vent pipe is typically one of the first things to leak on a roof. With that in mind, let’s focus on some helpful tips to resolve any potential leaks from the plumbing vent on your roof.
- Whenever there is a pipe sticking up from your roof, there is also a specifically designed type of flashing for that pipe.
- Your shingle might be a 25 year or 50 year shingle but few pipe flashings are actually designed for that length of time.
- Most builders install a pipe flashing that lasts approximately 7 years.
- Learn how to pick the right flashing for your vent pipe
How the Plumbing Vent Works
The plumbing vent pipe you see in your roof is attached to all the sinks, toilets and water sources in your home, which ultimately drain into the sewer. There are two main reasons for these plumbing vent pipes.
- To help the water drain out of your house, just like the tiny hole in your coffee lid functions.
- Prevent sewer gases from entering back into the house.
