Maybe a dumb question, why don't they just make shingles that reflect the solar energy a lot more?

They do but they are expensive.

Or if one needed to replace their roof, they could go with the lightest color, closest to white, as possible - if they could tolerate the color and their HOA (if applicable) would allow it (not likely). That alone can reduce attic temp near 20 F in summer.

I put it up in a pole barn with a metal roof/siding when it was built and it stays pretty cool in there. Will probably add it to my attic at some point.
