Let me see...in the winter, when energy costs are the highest, wouldn’t we want a dark roof to capture all the heat from any sun possible????
Shhhh. It’s another jobs program. Carpenters to flatten everyone’s roof and then another crew to paint them all white.
Of course, this won’t be necessary once homes are foreclosed on and everyone is forced into state coordinated “smartgrowth” towers.
