Q: I have a garage in my backyard that I use as a shop and it measures about 24′ x 18′. There is no type ventilation in the roof whatsoever and it gets boiling hot in there when it’s closed up. I’m not wanting to spend a lot of money and I’m not real handy, but I’m thinking that some gable and soffit vents might help cool it off.
I wouldn’t be able to put them directly in the middle of the peak of the Gable because there are support beams in the way, so I was thinking that I might put a one on both sides of this beam as high up towards the peak as I can ,thereby giving me 2 in the front and 2 in the back for a total of 4 Gable vents and then putting in several in both soffits.
So, do gable vents HAVE to be in the middle or would I be OK with 2 just near the top & middle of the Gable as I described?
A: Gable vents would not have to be dead center.
If at some point you can add a ridge vent and also have as many eave soffit vents as possible, I would encourage you to do that and to then eliminate the gable vents.
You also may sometime wish to consider a light colored roof or a roof with reflective pigment.
