Was that based on stock white shingles or shingles painted white?
Because surfaces painted white reflect roughly 90% of the sunlight,
while regular white shingles reflect only 10%.


Years ago, a flat roof in Florida had a white quartz on them. In the
desert here, I have seen a couple that used white rocks. Strange,
considering the weight of the rock of the roof and the home age.
