Why Would Roof Tar Be Applied To Top Of DWV?

Don’t know why it comes up sideways sorry

It looks to be sealing the decorative copper wrap put over the original pipe material.

It looks like they are trying to make a copper flashing of some sort. Similar to a lead flashing which encapsulates the entire pipe and wraps around the top of the pipe. Not a very good method. Call it out.

It is not properly terminated and that sealant is temporary. You will see it molded/hammered over the top and bent over into the pipe or a termination ring.

I agree, call it out.
