I tried asking this previously but don't think I framed my question properly and didn't get any responses despite having asked similar questions previously where I got tons of great responses. Gonna try again...
This is a 17'x19' detached garage which was built in 1942. Standard gable roof. Zero overhang on the gable sides, very small (~10") eaves with no built in soffits. Stucco walls. It's an open, vaulted ceiling with no insulation or drywall. Zero venting installed anywhere. See below for a cross section view.
I would like to add insulation and then drywall the ceiling so it looks nicer, stays cooler in the summer and warmer in the winter. I'm aware that if I add drywall that I need to figure out some kind of roof venting. I wanted to see if my idea will work or not. I'm thinking that if I add vents between the rafter tails then vents or a fan to the "attic" portion just under the ridge that it should provide the needed ventilation.
Front of the garage:
Side of the garage:
Cross section drawing showing the open ceiling framing. I would want to put drywall on the underside of the rafters and collar/rafter ties. This would leave a small "attic" space right under the ridge.
Based on my research the way I have this setup is essentially a combo of how a vaulted ceiling and a regular attic would be insulated and ventilated. Sort of an odd configuration so I wanted to see what people thought. Originally I wanted to do spray foam but now looking to save some $ by skipping that.
Thanks!
