Unless your furnace is older than the 1980s you are probably dealing with double walled vent piping.
See comment 3 above.
There are 3 gas furnaces and ac units.
Or you may have a distance issue.

Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys.
The roof is a t shaped gable roof.
In contrast modern high efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials such as pvc cpvc or abs for their exhaust vents some high efficiency furnaces also include a plastic pipe for intake area and all types.
You may have a bad boot around the roof vent that is leaking into the attic.
