How will the addition of a reflective insulation with an airspace between the roof deck and the aluminum surface change the conditions that cause condensation?

A reflective insulation below the roof deck results in an interior surface temperature that is greater than the outside temperature (in cold weather). As the inside surface temperature increases, the conditions for condensation become less likely to occur.
