if open cell spray foam is used for insulation under a metal roof will it harm the integrity of the roof or shorten the life of the paint or warranty?		Guest User 5/16/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11423/find/
It shouldn't. It would be best to ask the specific manufacturer of the product you plan to use.		Ken Buchinger NCI Building Systems, Inc. 5/16/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11424/find/
