Wait....what? Am I misinterpreting this or do have a litre or two of water in the ducting from your exhaust fan to the roof cap? It.....shouldn't have any water in it, let alone that much. Sure you'll get a touch of buildup in the extreme cold temps when the most air condenses on the cold pipe, but generally it should evaporate as you run the fan.
Couple suggestions:
- Insulate pipe better
- Swap pipe from metal to a PVC pipe (I use rigid PVC drain pipe).
- Run fan longer after showers to help dry the line out (consider a fan timer)

Well, even if you had the hatch open, with proper ventilation it would ideally keep the attic close to the ambient temperature. So ya, I'd say your conclusion is correct.
