I'd prefer not to cut a hole in my roof, but to vent through a wall
I'll have to run 25' of duct.

Thanks.



Careful if that 25 ft run is thru the attic and
it gets cold where you are. Often, condensation
inside the duct occurs and runs back down to the bath.

Any chance you could mount the fan itself right in
the outside wall? They make a bath fan just for that.

Too late, it's already installed!

I'd generally prefer to go out a soffit, but 25ft is too far for the
condensation issue above as well as substantial reduction in fan
capacity. I'd go with a roof vent in this case, as long as it's close
and can be done on a side that's not highly visible.

what sort of vent would you use for puting the exhaust out a soffit? I have
about 8" of soffit, and it would only be 4-5' away
The only ones I have seen are for a roof, or wall type, that seem to need to
be vertical for the shutters to work.

thanks.
