My bathroom has a window but it can't be opened when someone is taking
a shower and moisture builds up fast.

I would like to install an exhaust fan in the ceiling but I have a tile
roof so it can't go out through the roof. My dryer was originally
vented out through the roof (it's at the other end of the house) but it
stopped working right and a man who does repairs came in and ran a new
vent pipe up into the attic and out through the soffit. It works fine.
I am wondering if there is any reason why I can't do the same thing
with the bathroom.



The thing I would tend to think about out the soffit (dryer or bath) is the
moisture quickly rises getting trapped under the soffit while the vent is
running...aka rot and/or mold. Can you run it out a gable end?
