I'm Suprised people don't just paint everything white in really hot countries. I've always felt that would probably help a lot.
True it would probably look bad a lot quicker.
always been confused why roofing in the NA area is often black, or close to black, it simply doesn't help anybody.
Also, the color doesn’t make that much of a difference. Like a percentage you can count on one hand. Much more significant gains can be had from ridge vents and other ways of getting the heat out of the attic, and insulation to keep that heat from going into the house.
At least according to my acquaintance in the roofing industry, and obvs this is regarding typical US/Canada SFHs
i could see the utility in it providing natural drafting for ventilation, but honestly, with the advent of modern homes moving towards insulated attics and loft spaces, that's definitely the correct choice.
