Set some ground rules to manage your expectations. Both of you need to be clear with what you expect of with each other during this long distance relationship. Set some ground rules so that none of you will do things that will take the other party by surprise.
As air is pulled from the attic space by the turbine vent, ridge vent or even an electric powered fan, the same amount of air must be allowed to flow into the attic space where the roof passes over the exterior walls of the home.
That way your drain portion is within the heated space but the vent is in the exterior wall. Once your vent is above the fixture level such as in your attic you can run it horizontally over to another vent so you only put one hole through the roof. The make sure the vent has a slight slope to drain so it doesn't funstion as a trap for condensation.
