Attic temperatures can vary as much as 20 to 40 degrees f which in turn can reduce energy consumption by 20. The greatest savings resulted from using white metal roofing see table 2 18 shown at left.

You probably know from elementary science that different colors respond differently to light and heat energy. Emissivity and how it relates to energy savings and cool roofs.
