Hello all. I had a question about the vent coming out of the roof. In my kitchen, I have a cathedral ceiling framed with 2 x 12 joists. I was planning on bringing a vent from behind my sink straight up through the roof. I have a 18" overhang, and this will place the vent close to the edge of the roof. Is there an issue with this? I don't know how well I've explained this, so if need be, I can sketch out something and attach it.
Thanks in advance for the help.
