re: roof colors--- not necessarily....
A new, good-quality metal roof will be coated with pigments that reflect the sun /keeps cooler. We installed a black metal roof a cpl years ago that had almost the same "SRI" (solar reflectance index, or something like that) as the lighter colored ones. We also have a really steep roof and our roofer said they are more forgiving than a flatter one, when it comes to retaining solar heat. We do have very hot summers here, but certainly you are further south so YMMV.
