    Can I just cut out the broken piece cut a little extra off the pipes and then install a new one? Is there anything I need to worry about the height of the pipe as it goes up and out of the roof?

    The International Plumbing Code (IPC), requires plumbing vent pipes
    to extend vertically at least 152 mm (6 in.) above a roof

    You will need to cut the santee out and replace it. The vent on top needs to be at least six inches above the roof. Normally I see them quite a bit higher than that, so I'm guessing you have something to work with there.

    NYC old code (1968) Vent terminal 5 feet above the roof 7 feet is used for other then weather protection

    New Code 2 feet above the roof which is crazy as we can get over 2 feet of snow up there

    I would worry about why that tape is there. I would open the wall more, and consider replacing more.

    Look at a pvc repair coupling or a no hub coupling for pvc might make the easyer. That fitting break looks like the pipe coming up was in a bind.

    I am thinking three of them, unless jhwmonk can do some precision measuring, cutting, and gluing.
