re: Why aren't white shingle or light colored roofs more common in the South and hot climates?

I don’t consider it that way. And I’ve never been a believer in global warming. But we just had the road in front of the house blacktopped. The heat reflected off it makes it unbearable to walk on. That made me think of the millions of miles of earth that has been concreted and blacktopped. That has got to be making a difference in earth’s temperature .
