Vented vs. unvented roofs: Need primer
I’m having a building designed for me [I gave a sketch of the floor plan I’d like to the draftsman].
Part of the roof will be engineered trusses. Part will be 12″ I beams to allow a cathedral ceiling over the great room, and windows along the south facing wall.
Now trying to learn the best way to insulate the roof and do I need to the roof to be vented or un-vented. Didn’t even know to ask the question [assumed all roofs were vented] until I joined GBA yesterday.
So, school me on roofs.
