In this case ventilation is required and the roof can still become wet with condensation which may cause materials to decay.

If there is not a vapor barrier it is recommended to have one for every 150 square feet. On most flat roofs however stack effect will be ruled out since all vent openings will be at approximately the same level and there will generally be only small pressure differences from wind.
