I had a friend who had a house & garage. The garage had a questionable roof. So he tore off the old roof and nailed a bunch of corrugated fiberglass on the roof because it was so cheap.
Now, I'm not saying that this is a great idea for a serious roof, but it was quite amazing how much warmth the garage had in the winter, even on an overcast day. He ended up using the garage a a place to produce edible seed sprouts on a medium size scale... it was enough to support his family in a modest fashion.
I'm not championing corrugated fiberglass roofing or even edible seed sprouts, but the heat gain was well worth taking note of.

THIS STUFF might be superb.
