So, is the roof installed directly on top of plywood or OSB? Or is it over old shingles? Or is it on battens above plywood or OSB? I understand there is no underlayment but what is beneath the metal roof panels?

According to the International Building Code, your roof should have underlayment.

Just had a exposed fastener metal roof installed on my pole building.
The problem is contractor didn't install any under lament. Already paid the guy. He did a nice job. Just no underlayment.
I heat building in winter. It is insulated.

They stripped off old shingles. Metal is installed on battens above osb roof.
Not sure what to do. Thanks
