Metal roof on purlins spray foam

We are doing a large addition and wanting to do artic white metal roofing on purlins and 1-2" closed cell spray foam directly to the metal. Is there any issues with this application? Warranty? Does there need to be a moisture barrier on top of the purlins? We are in SW Missouri.

Its a well approved application, however, I prefer to spray to the backside of some foam if you can.
