What do you think about insulation on rafters? Will it shorten the life of the roofing?

Below is what our roofing expert John Stout from Go Roof Tune Up had to say in response to the above question:
Extreme Heat and improper ventilation will cause premature deterioration of roof shingles. Having a Batt Insulation layer between rafters should not have a negative effect on the life of the shingles. Attic temperatures are an important part of the equation in calculating shingle life.
I think insulation between rafters would be without problems as long as it did not restrict the normal ventilation and would not create hot spots at the roof sheathing.
