Your roof will absorb heat no matter which color you pick. Choosing a lighter color will naturally be reflective and keep your roof slightly cooler. Studies have shown that lighter shingle colors lower attic temperatures, which can lower your a/c bill. However, when it comes to longevity tests have shown that it makes no difference. Notably, a properly ventilated attic will provide enough cooling to offset the increased heat retention of dark shingles.
