I just installed radiant barrier roofing material...
I wonder how that does vs infrared imaging?
Maybe shield it a little.*
Freeper project:
Get an IR camera, set it in front of a board with heat shield installed on it, let someone walk behind the board and check to see if the camera can see the heat signature.
*But I’ve heard that radiant barrier material lessens the life of your shingles, due to the heat reflection/ redirection.
