What product(s) do I give my roofer to install a roof vent for bath drain vent?

I have a 3″ drain vent that terminates in the vented attic space.
I am contacting my roofer to make a hole and add a boot onto 3″ pvc that I’ll stick through the roof (12/12 pitch) and then glue up myself to the drain vent. Could someone please direct me to the product(s) I’d need give to the roofer? I think just the boot and the pipe, right?
– What schedule of PVC is recommended for a roof vent that’ll see the sun?
– Are there certain boots that are recommended for high pitch roofs?
– Is it recommended to add something on the vent to keep debris out?
Basically I want to avoid finding a plumber to crawl through my tiny access panel and into the roof just to glue the pvc together. I’m pretty confident that I can do that.

You should be able to match the existing piping and just extend it through the roof. The roofer should be able to provide the proper boot for your roof (link to article below). Not recommended to add anything to the top of the pipe, it may restrict air flow.

Here are some recommendations and considerations:
Schedule of PVC: For a roof vent exposed to sunlight, it's recommended to use Schedule 40 PVC pipe. This type of PVC is durable and UV resistant, suitable for outdoor applications.
Boots for High Pitch Roofs: Yes, there are specific boots designed for high pitch roofs. These boots often have taller collars to accommodate the steeper angle of the roof. When purchasing the boot, ensure it's suitable for your roof pitch.
Debris Protection: It's a good idea to add a debris guard or screen to the vent to prevent leaves, twigs, or other debris from clogging the vent pipe. There are various options available, including mesh screens or caps designed specifically for vent pipes.
Regarding the products you'll need to provide to your roofer:
Boot: Look for a roof vent boot suitable for a 3" PVC pipe. Ensure it's compatible with your roof pitch.
PVC Pipe: Purchase Schedule 40 PVC pipe with a 3" diameter. You'll need enough length to extend through the roof and connect to the drain vent inside the attic.
Debris Guard: Consider purchasing a debris guard or screen to accompany the vent to keep debris out.
Before proceeding, it's essential to check local building codes and regulations to ensure compliance with venting requirements. Additionally, if you're unsure about any aspect of the installation process, consulting with a professional roofer or plumber can provide valuable guidance and ensure the installation is done correctly and safely.
