To clarify: do you want to keep the surface of the roof cool, or the attic/space under the roof?

I have a "hot-mop" roof now (black) and a very low pitched roof with no attic and no insulation. Therefore the house gets super warm inside in the afternoon- the roof coating absorbs all the sun's heat I guess. I'm trying to find a way to keep it cooler inside; my ceiling fans can't keep up with the heat. Thanks!

Well if you had an attic I'd suggest looking into soffit vents, a ridge vent, and even an attic fan. But I'm not sure if those will work for you in your case. (you could still look into those though)

The best option in my opinion is to get some form of a Radiant Barrier. It's usually some kind of reflective material that you apply on the inside of the roof. I'll see if I can find some links for you.

Basically what you're looking for is an aluminum-type film that you staple up to the rafters.

Or you can check out this company

They have a spray based coating for the inside of the walls. That wont cool you down as much as the foil, but it will help.
