This is from todays inspection. The vent is only terminating out of the roof, 7". We live in Ohio and the snow that we can get here might just seal the pipe off.
I looked up on the IRC book, section P3103, And they do not give exact lengths? It must be based on regions.
I believe it’s 6" plus anticipated snow depth.
If I had that sewer stack here, I’d simply recommend an extension.
Not really a big deal though as snow will simply fall inside. Unless of course they get ice damming issues.

Thats what I am going to do.
you did recommend replacement as the collar is starting the crack?
