One might want to get up on the roof this fall, and cover it with "Bubble Wrap" held down
with "Plastic Netting".
I researched this for a builder in 1992. The stuff with bubbles over an inch is almost as good as double pane glass.
In 30 F air the temperature of a metal roof increased to 130 F in direct sunlight.
It should float on a pond or swimming pool. Good for windows too.
