If this is a plumbing vent the height would only need to be 6” above “expected” snow levels. 12” is the normal height for Chicago and that code has been in place and worked well for decades. It’s not directly under a window and may be 10’ from any operating window. The location is fine and does not need to be extended to the second roof. Best to consult a local plumbing contractor if there are any questions.
A: Insufficient vent support.
B: Vent termination extension reduction.
C: Suspect: Circumference too small. Not 3" inch.
Code Citation
904.2 Frost closure. Where the 97.5-percent value for outside design temperature is 0ºF (-18ºC) or less, every vent extension through a roof or wall shall be a minimum of 3 inches (76 mm) in diameter. Any increase in the size of the vent shall be made inside the structure a minimum of 1 foot (305 mm) below the roof or inside the wall.*
The window doesn’t open.
- Where the pipe exits the roof it must at least 10 feet from any windows that can be opened. The radon pipe needs to be at least 12" above the plane of the roof.

I agree the window doesn’t look like a window that will operate.
Are these the NSPC codes from the OP’s jurisdiction? As I always say…contact a local plumbing contractor.
I concur.
Don’t often see through roof or wall air vents terminating this high because of the clearance.

I think that’s a good idea Robert because the UPC and the IRC are very different when it comes to vent terminations. I believe New Jersey follows neither code.
There were a lot of remarks on this forum all varying greatly because of the two standards. I doubt anyone quoted accurately from the OP‘s jurisdiction.
I believe a good solid practice for a home inspector is to call out a plumbing vent directly under an operating window or within 10 feet horizontal of a operating window.

I never report code. I would report Insufficient support and make my recommendation.

Any chance it is a furnace vent, they are the only PVC vents that I am aware of that allow a reducer like that.
and if radon vent it must discharge above the highest eave

Thanks all, it is not furnace vent and both are on the other side of the house. I described it as not up to modern standards and have it checked.
You guys are very helpful.
Thanks again
