Several major tests that have been completed have shown that dark materials, like shingles, asphalt and tar, only reflect 5-10% of the sun’s rays. This also means temperatures rise 70 to 90 degrees more than the air around them. White roofing materials, on the other hand, will reflect as much as 25% of the suns rays with a 50 to 70 degree difference in the surrounding air. Some materials will reflect as much as 35% and only 60 degree differences.
