I'm considering using this paint on the underside of my garage attic
roof deck. I have asphalt shingles, and the underside deck surface
temperature can be 130 degF in the summer. Even after the sun goes
down, the heat soak in the shingles keeps the underside of the roof
deck a radiator for hours.
I'm wondering how much temperature difference to expect on the roof
Any experiences / real-life data with these paints?

If you reflect a lot of the heat back up through the roof structure, what do
you suppose will happen to the asphalt shingles? A scheme with soffit and ridge
vents might be more beneficial even if it's more trouble. Worth considering if
you need your garage more temperate. HTH

I just replaced a roof 8 years early, primarily because I didn't
have ventilation on the bottom of my roof deck. I'm positive that
you will drastically shorten the life of your roof with the radiant
barrier. Don't do it or else provide a false deck with 2 inchs of
sophit ridgevent ventilation .
