Q&A: Insulating a Flat Roof in a Hot Climate

Q: I am reroofing a flat roof framed with 2x10s on a house in Tucson. The foil-faced batt insulation was installed more than 25 years ago and seems very spotty, so I’d like to replace it while the roof is stripped. Winters are mild here, but the summer heat is brutal. I use both a/c and evaporative cooling depending on the outside humidity level, so humidity inside varies. What’s the best way to insulate the ceiling joists to provide ventilation? And how should I handle the vapor barrier? Since I don’t want to remove the drywall ceiling, is there some way to coat the back of the drywall? Or can a synthetic roof coating be used as a spray-on vapor barrier? More
