Black Shingles=Bad News???

I am going to put a new roof on my house soon. The local roofing supply has a closeout sale on Owens Corning 30 year shingles, the only problem is they are Black Onyx. The roof I am replacing is black and you can tell it's pretty aged. My questions is will this roof that has alot of sun exposure age prematurely in the sun being black? I was going to get a lighter grey but the black onyx shingles are about $4 a bundle cheaper. Thanks for any replys.

Asphalt shingles have low reflectiveness. Black, of course, is the least reflective at 5%. White shingles reflect at about 20-30%. See chart: http://eetd.lbl.gov/coolroof/asshingl.htm

Sunlight and extreme temperatures can cause asphalt shingles to curl and buckle. A consideration with asphalt shingles is adequate attic ventilation. This is especially important for dark shingles. Attic heat can literally bake asphalt shingles.

Here's an interesting study that shows that geography, direction, and shingle color have a greater impact on shingles than attic ventilation: http://www.professionalroofing.net/p...2/feature2.asp
