It used to be common to vent into the space above the soffit. That is no longer allowed. You can vent through the soffit, ie the exhaust goes to the exterior below the soffit. Depending on how the soffit and roof are constructed there isn't always space to do this.
If you're referring to me, 18:02, I'm not sure how I am confused, and I think you are misinterpreting me...I said (about soffit venting): "You might also be able to vent out and down through the soffit (and if it is near a window then you can open the window to access the vent and clean it)." I said "out and down" meaning not into the soffit cavity but with an exhaust termination on the surface of the soffit and having the exhausted air blow out into the open atmosphere. You should never vent into an enclosed space since it will just build up moisture

Any time you make a perforation in the building envelope you run the risk of creating a leak. That risk is highest in the roof and lowest in the soffit.
If there is no other alternative the roof is acceptable but it's not preferable.

Anonymous wrote:Sorry if this is a dumb question! We purchased a home built in the 60s and the bathrooms have fans that don't seem very effective. When we looked in the attic, they appear to be venting through an open tube straight into the attic. Should they actually vent through the roof? If so, what kind of person should I hire to do this kind of work?
