I have a finished attic with bathroom where there is currently no exhaust. I am thinking of installing an exhaust fan in this space. I have following questions.
1) Can I install a fan that directly vents thought the roof?
2) What kind of exhaust fan do I need? I imagine space is tight between the finished drywall and roof boards.
3) Can this type of installation cause any moisture or ice-dam issues as the part of the insulation will have to be removed to accommodate fan? I live in the northeast.
