^^ The only comment to the above is that the IR radiation has to penetrate the roofing to get to the radiant barrier, after which it gets reflected and returns the same way. In effect, it goes through the roofing material twice, leaving some of its energy (heat) in it each time. This can make the roofing warmer than without the barrier, and the higher temperature can shorten its lifetime.

This is why it is better to reflect heat closer to the source.
