Researchers created a roof paint (a “nano-engineered polymer coating”) “that not only reflects up to 97% of the sun’s rays, but also passively collects water”. And kept the interior of the building 6°C (~11°F) cooler.

We painted our (formerly black) flat rubber roof white this past spring after thinking about it for a few years. Wish we had done it sooner!
Cooling bills were definitely lower and it was just easier to keep our top floor condo comfortable. I’d recommend it to anyone-the currently available roof paints seem to be quite good.
I'm thinking about doing this for my flat rubber roof. What product did you use?
We used the gaco roof 100% silicone product. First coat gray, top coat white (so you can see what you’re covering the second time). We used this one because it was easy to get locally and we could return unopened 5 gallon containers-I think a few of the products out there are pretty similar. Which was good because we needed quite a bit less than we thought to get good coverage.
Make sure you clean the roof really well first. And try to do it before it gets too hot out…
