Put a styrofoam baffle under the roof deck before spraying the foam. This will prevent one side of the deck boards from being smothered and potentially cupping the boards. Wood shrinks and swells with the seasons, which is why both sides should have access to air.

It really shouldn't make any difference. Make sure and use wood decking and not OSB OR plywood for the nailing surface though

Is there any reason not to use spray foam insulation beneath a slate roof? This is new construction, with the whole house using closed-cell foam insulation, and the attic will be a finished room.
