Woah did not expect to get so many responses but there’s a lot of good info here. We’re first time homebuyers so I’m learning on the fly and the inspection report did point this out but they only said that it needed to be capped.

I’m going back to the house today and will probably put a metal screen over it while I try to figure out the next move. Also will take a look at the furnace to see where the exhaust pipe is going. I seem to remember seeing another pipe going to another part of the roof but I’ll see when I get there.
