Is it a good idea to vent a bath fan exhaust out of eyebrow roof?
I originally liked the idea of venting the bath fans out a gable end of the house in order to minimize roof penetrations on the steel roof. I did some research into venting through the main roof soffit vents, and obviously that is not a great idea due to the possibility of drawing moist air back into the roof.
However, I will be having a couple eyebrow roofs over the windows on the gable ends that seem like would be excellent spots to exhaust the bath fans. I originally intended to use non-vented soffit on these small roof sections, but perhaps I could use vented soffits here and dump the bath exhaust air into these?
Can you think of any implications or downsides to venting into / out-of an eyebrow roof?
