The attic may very well be cooler however, less than 17% of radiant energy enters from the attic to the home. Heat doesn't radiate downward very much, this should not surprise anyone as heat still rises.
The home is the concern, not the attic.
Radiant barrier can increase shingle life, however, your roof replacement will be dictated by the insurability of your home not the condition of the roof. A sad, but true statement.
