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?

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.

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.

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.. .

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.
