Should i still lay down the recommended 1/4" fanfold insulation over the shingles to act as a vapor barrier even though there is no heat in the building? Jason		Guest User 6/15/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14849/find/
No reason that you need a vapor barrier if the space is unheated. Make sure that you lay down a slip layer to protect the underside of the metal roof.		Eric Novotny An informed customer is the Best Customer! 6/15/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14850/find/
