There is not debating whether or not lighter colored roof shingles save on cooling costs for homes.  Lighter shingles help keep your attic temperatures down. However, when it comes to whether light roof shingles last longer than dark roof shingles, there is no definitive answer.

According to Family Handyman:

One major shingle manufacturer I spoke with said its tests showed no difference. Its position is that a properly ventilated attic provides enough cooling to offset the increased heat retention of dark shingles.

But some studies dispute that. They claim that since heat always increases molecular activity, and since dark shingles always run hotter, the heat factor alone dictates a shorter life for dark shingles. Yet another study suggests that the sun's UV rays play a much bigger role in shingle degradation than heat.

In a nutshell though, most experts agree that the most important thing when it comes to roof systems (and the longevity of its shingles) is proper attic ventilation.  So, make sure you have enough roof soffit vents and you should be fine, unless you want to save money on cooling costs, and then you can also pick the lighter colored roof shingles.
