I am trying to figure out the best way to properly vent a hip roof with almost no ridge and exposed rafter tails, which means no soffits. The intake for the venting can be done between the rafters with a product I found (raft-a-vent) but the exhaust has me puzzled. supposedly, power roof vents disrupt the air flow for this application. I do have 2 dormers so I may have to creatively vent through those. Ideas? I am using AP metal panels for the roof. The house is 50 feet square, 2story, in central Texas.
