Back half of the roof completed from north west corner.

Roof framing. The center will be solid foam extending 8 inches past the gable walls so there is no thermal transfer through joists. We filled the center with 8 inches of rigid foam then used 10" logs screws with washers to screw stringers on top of the foam into the decking and rafters underneath the decking. The metal roofing then screws into the stringers.
