Thats very likely BUT lighter colored roofs reflect more heat thus the
attics are cooler so the shingles last longer. I recently sold a home
with gable end and ridge vent. The home inspector wrote it up because
the attic was 20 degress warmer than the outside on a hot july day. He
recommended adding power vents to the roof.

That inspector was uninformed. Power vents might be an OK idea if they
are solar powered, but the University of Illinois did a study in 1990
that showed that the cost of operating power vents exceeded the energy
savings in a properly insulated attic.
