How Many Types Of Pipes Are On My Roof?
Depending on where you live will determine the type of pipes that are on your roof. Roof vent pipes can vary based on the local building codes. Let’s take a look below at what vent pipes you might see on your roof.
- Plumbing vent stack – This vent pipe is installed to allow gases to be released from your plumbing lines. Also, they create pressure in your plumbing lines so that you can flush your toilets.
- HVAC vent stack – This vent stack is used to allow fuel or gas to be released from your burner, fireplace, boiler, or water heater.
- Attic fan – The attic fan pulls hot air from the attic and releases it through the vent. This keeps the attic dry and free from moisture. Most attics with attic fans on their roofs are in southern homes.
- Small vent box – This vent box is used to suck moisture from your bathroom out of the air and releases it into the outside. Typically, there are mesh screen coverings over these vent boxes to keep rodents and birds from nesting in them. Additionally, you might see a clothes dryer vent on the roof.
For example, roof vent pipes. What exactly are they for? Roof vent pipes are to allow air to escape the plumbing and keep the plumbing pipes pressurized. Should a roof vent be covered? Covering a roof vent pipe should only be done to keep debris and bird nests out of the pipe.
What Is A Vent Boot?
Typically, a vent boot is used to cap your vent pipe. It is a rubber vent cap cover that seals the pipe to protect it from debris and dirt. The use of rubber material to make the vent boot allows it to expand and contract under various weather conditions. Keep in mind that vent boots can break down due to extreme temperatures. Let’s take a look at how we can tell if a vent boot cover is worn out.
- The paint on your interior walls will begin to crack.
- Any wallpaper that you have on your walls will begin to peel.
- You will notice water markings on the ceiling and your walls.
- The vent pipe will have damaged shingles around it.
What Are Roof Pipes And Boots?
Throughout your home, you likely have exhaust fans in your bathrooms and/or a range hood in your kitchen. These fans can help move hot air and unwanted smells out of your home through vents that lead to your roof. There are also plumbing vents that run through the walls of the home and out the roof. These pipes regulate the air in your plumbing system. Wherever the air vent is coming from, it terminates on your roof and might look like a pipe sticking out of your roof.
In another article, we told you all about step flashings. While boots might not look like step flashings, they serve the same purpose and are technically a premade type of flashing. With the help of a little silicone sealant, boots fit securely around the base of roof vent pipes to seal the pipe from outside elements.
Two Types Of Roof Vent Pipes
There are two main types of roof vent pipes: those that are vented and those that are not vented. Vented roof vent pipes have a hole or openings that allow air to flow through. Non-vented roof vent pipes do not have any holes or openings, so they rely on convection to draw air through them.
Roof Vent Materials
Roof vent pipe and boot products come in a variety of materials, including metal, plastic, rubber, fiberglass, asphalt, wood, and more. It’s important to choose a material that is durable and will withstand the elements. Some materials are better suited for certain climates than others. For example, metal is a good choice for areas with high winds, while plastic is a better choice for areas that are prone to moisture.
