Unpopular opinion: I thought spray foam was a waste for a container roof, but my Reno build proved me wrong
We had a 1/4 inch condensation drip after the first cold night, but sealing the roof seams with closed-cell foam fixed it completely. Anyone have a better method for preventing interior moisture in a dry climate?

What about a vapor barrier under the roof panels? That helped my build a lot.

My Reno had the same drip problem. Honestly, spray foam was the only thing that worked for good. I wouldn't mess with anything else now.
