I would like to build a metal-clad roof.
The roof will have 2×6 16″o.c., rbs, and R-13 batts stapled to the inside of the attic, leaving an air space below the rbs, so air can flow from soffit vents in each bay to a ridge vent at the top. Does this make sense? I plan to insulate the 2×6 ceiling with closed-cell foam. Thanks.
