What is the consensus on radiant barriers and how they affect roof underlayment, decking and shingles themselves?

Does it make any difference at all? Are they getting that much heat anyway? Is the barrier sandwiching extra heat between the shingle and the barrier?

Although shingles can get hotter with the presence of a radiant barrier research studies in FL show that they do not shorten the life of the roof. That information is on-line.

Whether it truly impacts it or not, do shingle mfgs warranty the product with radiant barriers installed? I honestly don’t know. That would be my primary concern.

I’m thinking about setting up a little experiment to prove the radiant barrier concept to myself. I understand the science but I’m still a skeptic.
