We are currently installing a standing seam metal roof to a new building that has osb plywood roof covered with 30# felt. The owners stopped us from installing the roof panels over damp felt because they said that they had read online that this will cause the screws to rust and eventually fail and the osb to deteriorate over time. What's your take on this?

It would be fine damp.

I would use a climaseal screw or other similarly coated screw and be done with it.
Obviously the best of both worlds is to let the roof dry out but if you need to get it down, you have to get it down.

As long as the wood has a direction that it can dry to (i.e. attic space with ventilation or air space behind panel).
I would be potentially concerned with the expansion or contraction of the wood when it dries and what the will translate to in terms of the fitment of the roof and any sealant adhesion issues on flashing.
