Every building I have has a metal roof. If you provide ventilation, or if lacking that, insulation, they are no more uncomfortable than any other type of roof system. Hey, I live in Arizona. If they were hotter than other types of roof, I would notice. I've had no cooked, or frozen chickens. The are much longer lasting and more durable than most other materials. I like metal.
After doing a little research, I ran across some interesting information on the heat reflecting properties of metal roofing. White painted metal is one of the best in keeping things cool. Here is a link to a Florida energy study:
