Customer has talked to inspector, who says they dont care. So i say instead of spraying between trusses, we just spray to roof deck with 3 inches of closed cell foam. does anyone have any comments on this. Roof is steel with underside plywood. Should i allow for Morvents to be installed? Or do i just spray directly to roof deck. This is my first roof by the way. Thanks....
