You want the hot air to have a way to get out and since it rises, you want the vent close to the peak.

Yes, that does make sense. Thanks! And there are indeed 2 vents up near the peak of the roof, one on each side.
So, do people normally attach the ceiling to the underside of the rafters or lay them on top of the rafters? Or is it just personal preference?
