Hello Gentleman- Is OSB or plywood roof sheathing required with a metal roof or can the metal sections be fastened to the rafters? Thank you for your time.

Some metal products can be installed to battens spaced horizontally spanning the rafters. Many residential products though require solid deck. Also, particularly if decking and underlayment are not prosent, there will be a need for good ventilation, a vapor barrier behind the ceilings, and good attic insulation in order to avoid condensation problems. Always make sure that the product you've chocen is being installed according to manufacturer instructions.
