    Built in 1935, the shower drain stack needed to be replaced.

    The plumbers stopped just short of the roof and attached the old galvanized Youngstown pipe to the PVC with a clamp.

    Is this the proper way to do it? On the roof, the vent is pretty rusted but I guess it is still holding together. Just not sure they would go through all the trouble of three floors of 2" drain replacement to stop a few feet short of the roof.

    That looks to be the right coupling between the two pipes.
    A metal wrap to prevent the pipes from shifting.

    I guess that was their stopping point, or maybe I can stay it's where the bucks stopped.

    My guess is they didn't want to disturb the roof penetration.
