I am considering using standing seam on a reroof of a manufactured home. This is a gable roof constructed of 2x6 at 16"o.c. with va;ulted ceiling. My contractor will tear off the existing ashpalt shingle(required by mf'd home code in CA) and install 2x3's vertically over the existing deck which is only 1/4" ply, and attach them to the 2x6's. Then apply 1/2" OSB with TechShield reflective barrier. The TechShield would face down and the SS Kynar coated panels would be applied to the new decking. This would create a 1 1/2" air space fron eave to ridge vent. Prior to installing the roof we plan to blow in more insulation in the cavity between the 2x6's (existing rock wool is sparse and has settled unevenly). I am located in inland So Cal, so cooling is more of a problem than heating. Do you think this method would achieve my goal of better handling high temperatures? I had originally planned adding rigid foam insulation, but that approach also has problems, i.e., practical thickness, venting, added cost.

This sounds reasonable but proper details at the eave and ridge are essential to ensure good airflow ventilation. Install an appropriate underlayment (check with the metal roofing manufacturer) on top of your new OSB.
