I have an unvented garage with a hip roof that I am looking to add a mini split and insulate the roof. I thought that if I insulate against the sheathing, it needs to be spray foam. I had two insulation contractors come out and both said they recommended installing R38 fiberglass directly...

Downside of insulating with no AC is that the building will not be able to cool down overnight and will retain the heat.
