Without building a new roof system, your best bet is probably to spray the underside of the current roof with closed cell urethane foam. Please keep in mind that your situation is a little unique and not typical of all metal roofs, because of the exact construction that was used.

Lets see a picture, but your best option at fixing it is going to be application of SPF with an approved barrier.
What do you believe is the source of the condensation?
typically when we see issues with condensation it is from humans or other living things.
A typical human person will put 3 whole pints of water into a space just by existing every 24 hours..
If this is just a metal storage building, what's getting the humidity up on the inside to cause it?
I have a storage building that is 16 by 44 it already has a metal roof and I am having a bad condensation problem I've already lost tons of stuff ruined by the condensation how can I stop this!
