Oh yeah, I love learning things. It doesn’t mean I love actually doing them.

I’m not familiar with that library.

My roof only has like a 4" overhang with no sofet so that isn’t an issue in my case.

Yup. With the vermiculite insulation in my attic and the moisture from that vent, I practically have an ideal mold farm up there right now. I need to fix that vent before it gets too much worse.

Weird. Must just be one of those regional things. All of the ones I’ve ever encountered that I know of went out the roof. Good to know going out the side is normal somewhere though.

Now that you mention it I have a dryer vent that’s exactly like that. If something like that works for warm moist air from a dryer then I don’t see why it wouldn’t work for warm moist air from a bathroom.

Theres no sofets on my roof (only has like a 4" overhang) so that shouldn’t be an issue on my house.

It’s just a cosmetic defect. But if you’re really woried about it then you could just replace it. Breakers aren’t that expensive.
