Insulation under existing metal roof | Ask The Experts Forum

Andrew Berezowsky 11/27/2016	I have a gambrel-roofed pole barn with a metal roof. The underside of the metal is exposed. The peak is vented. The metal is on battens. I would like to install insulation under the roof, but am unsure of the best way to go about this. Can anyone give me some advise? Thanks.. .

Todd Miller Isaiah Industries, Inc. 11/27/2016	Can you possibly install the insulation so that a vented air gap remains between the insulation and the back side of the metal? That would be my advice.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21662/find/
Guest User 11/27/2016	Thanks for the reply. I could use foam baffles between the metal and the insulation, but that would preclude using spray foam, wouldn't it?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21663/find/
Eric Novotny An informed customer is the Best Customer! 11/27/2016	How about a picture of the roof? Structure and accessibility will dictate if you have to use Spray Foam of if you can tackle it other ways.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21664/find/
Todd Miller Isaiah Industries, Inc. 11/27/2016	If you can use closed cell spray foam, you can probably get by without the ventilation. Spraying foam direct to the back of metal roofing creates a real challenge if the roof ever has to be altered, repaired, or replaced.
