Is this on the same house with the gas vent you posted in the HVAC section?
If so, then your problems are solved.
The 40 year old roof needs to be replaced. Then, while replacing the roof, replace the gas vent with Type B gas vent, install a proper gas vent flashing and gas vent cap, and don't forget to has a structural engineer design appropriate repairs for the overheated and darkened wood rafter and roof sheathing where the old gas vent was too short.
My guess is that the old gas vent cap blew off, and, to be able to protect the hole, they had to remove the top section which went through the roof flashing, now they would screw the pie tin on.
