How to Install a Roof Flange for HVAC

[@mattphilleo971]

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.

Best video. Quick and to the point. Thanks

Glad it helped!

What can be used to support the pipes below the roof, in attic?

[@schoenroofing]

Usually pipe straps. Hvac takes care of that part of the job.

Why don't you have to seal or try to seal the two bottom screw holes that you put right through the shingles and the roof?

[@schoenroofing]

These screws have a neoprene gasket that keeps water out. We find they hold a lot better than nails and caulking.

Did I just see a hole drilled next to where the hole should be drilled?

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

I'm glad im not the only one who laughs when they say no chalk.

the 2 exposed screws may cause water leaking?

[@schoenroofing]

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