Fiberglass is cheapest, foam works best. Insulation followed by a vapor barrier/retarder should stop the sweating. Vapor barrier/retarder will need to be air tight to the roof. Any leaks will lead to condensation.		Eric Novotny An informed customer is the Best Customer! 9/17/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/15175/find/
