How to Install a Roof Flange for HVAC

Hey!
Thanks for watching.
In this video I show how to cut and install a roof flange for a 2” PVC pipe. These are used with high efficiency appliances such as furnaces and hot water tanks.
The metal flanges are not as wide as I like so I show how to make a gasket to keep out moisture.
Enjoy and share with your friends who enjoy watching other people work 🤘

I'm looking for videos on this topic because a friend and I will be installing a 3" B-Vent pipe for a gas heater in my shop/ art studio. This is the best method I've seen yet for putting in a flange. It actually makes sense! I was thinking of using self-sealing metal roofing screws for the exposed part of the flange, and I was glad to see that you use them. Most people either use nails or nothing at all. I think the way you did it will ensure the flange stays secure to the roof and nothing will leak either. Thanks for the video!

Appreciate the comment. This is a bulletproof way to install flanges.

Only thing I might suggest is the upgraded cupped rubber flange screws for metal roofing.

Thanks! Hope it helped or was at least fun to watch.

the 2 exposed screws may cause water leaking?

@@YihuaWang-gb9dh the screw have neoprene gaskets to seal against the shingle. They are much better than nails with caulking. Thanks for the comment!
