not necessarily. there is enamels/urethanes that keep dark colors cool, just by a high uv rating...it needs to accept uv to accept heat, and then be able to give it away again.
a roof should get hot, there is organic and gases in the house that need out, and other physics that just needs up, unless you have a common sensed air circulation?
making a dirty old barn out of the house ...ewww.
