Hey everyone! I'm in the middle of a renovation for our main bathroom, and I'm facing a challenge. We want to install an exhaust fan, but there's no existing vent. The bathroom has a flat roof that slightly slopes towards an exterior wall, and I'm not seeing any space to run a vent outside. The roof is pretty new, and I'm hesitant to make any holes. The other walls are all interior. Any creative suggestions for venting the fan without compromising the roof? I've also shared some photos and a rough drawing to help visualize. Thanks for any help!

Check out this Panasonic WhisperWall exhaust fan. It can be mounted on the wall, and while it might be 15-20 ft away from the shower, it’s definitely a viable option if you can’t vent through the roof directly. It’s energy efficient too!
One suggestion is to run a PVC pipe through the roof to connect to the vent duct. It's become a common method, and while it does involve making a hole, it could solve your issue! Just make sure you seal it well to prevent leaks.
That's not a bad idea! It is still a hole, but PVC vents are pretty standard. Thanks for the suggestion!
You could look into using rubber flashing to help seal any areas where you might need to put a vent through. It might be worth considering as part of the overall strategy for venting without compromising your roof.

Interesting! That could definitely work, though I worry about the distance from the shower. Still, thanks for the lead!
