I just watched a 52 minute video by what seemed to be a very smart, arrogant, engineer. I think I'll stick to having it ventilated.I know in a home if you insulate the back side of the roof you need to install the foam board they sell that keeps an air gap to the roof boards to allow air to flow between the insulation and the roof board.

God! could ya just give me a few minute break. lol
