You have to keep the warmer moist air in the building from touching the cold metal roof and then condensing liquid water. Think beer can in the summer. Seems to me like insulation under the cold metal roof is your best answer. How to best do that is another issue.
Reducing moisture by sealing off the floor would help too.
