This is on a pole barn. If a roof is aluminum and we are switching to a metal roof that will have 3: 3' x 10' skylights in it. Would you recommend a vapor barrier(1/2" thermax) to prevent dripping? This is cold storage from my understanding with a concrete floor. I am thinking only if he has livestock or heating it does he need a vapor barrier especially if he has 3 skylights in it.

I agree with you. Vapor barrier is not necessary provided it has concrete floor, will not have conditioned air, and will not be used for animal confinement.
