I have a metal roof installed on purlins over rafters. There is bubble wrap under the metal and the seams are taped. There is a roof ridge vent and the soffit is vented. I am planning on using fiberglass batts to insulate the roof. Should I use rafter vents under the fiberglass batts? The room is not heated at this time, and there is no ceiling, but may be in the future.

Hi there. Are you referring to baffles between the rafters to create / maintain a vented airspace? I think that is a good idea.
