You know those pencils that change color with heat? That's because it's made with thermochromatic materials.
I had an idea. Why not put that on your roof? It lightens up as it gets warmer (reflects more light during the hot weather) and darkens as it gets colder (absorbs more light during the cold weather).
I do not know costs vs savings, but I think it would actually be substantial.
