There is a difference in the amount of heat that a dark shingle will absorb as opposed to a light colored one. Dark shingles absorb more heat, thus transferring more heat to your attic space. Light colors are just the opposite. There is a train of thought that says… Your dark roof absorbs more heat so it will wear out sooner. It is my belief that the quality of the shingle is the most important factor as to whether the roof fails prematurely or not. To deal with the heat transfer to your attic, from darker shingles, you must have your attic insulated and vented properly, thus keeping the attic air temperature as close as possible to the outside air temperature. The answer to which color to choose… Make sure you have adequate ventilation and insulation and choose a color you like!
Does it matter which color I choose?
