Just wondering If what I am doing is ok, I have an unheated building, roof is going to be OSB on top of the wood perlins, 30# felt, and metal roofing on top. I have been advised to put down some 1x stickers between the felt and the metal to prevent moisture from the OSB, to prevent rot, Any thoughts? I was told that the OSB will collect moisture, and mold in an unheated envrionment in the pacific northwest. Thank You!!

Is there going to be much air movement in the building? Condensation can be an issue ... it results when warm moist air hits a cool surface. To eliminate it, you need to keep that situation from occurring.
