Cool roof surfaces

xxx

I would greatly appreciate any good ideas anyone out there has for an elegant roof surface. I am currently working on a flat roof deck for an existing (large) residential home. We've put a new roof on- a 3-ply GAF membrane system with a granulated surface. The problem is: it's friggin' ugly. I'm currently trying to find a solution for something to lay down on top of the surface that would make for a nicer roof deck. It needs to be relatively lightweight and removable. So far, all I've been able to come up with is a rubberized tile system (think playground surface) -http://www.surfacingsystems.com/.
Does anyone have any more suggestions? Examples? Thanks.

I would love to. Unfortunately, the loads have to be minimal. It's got to be something fairly lightweight and treadable.
Since you brought it up, though, have you (or anyone) ever installed a green roof?

I recall a professor of mine did that once.
Goats trimming the roof... it's got a real 'green' feel to it.
Sorry, I have no technical information.

My last firm put a 3" extensive Hydrotech green roof system on a police station; I don't have access to the drawings anymore but I can try to answer questions off the top of my head.

Check out the GreenGrid roof system if you're shopping for a ready-made removable modular system, or just inspiration for your own solution.

Thanks for the suggestions, this is becoming really helpful. A question for the Hydrotech roof- did you install the hydrotech system over an existing roof system or was there an integrated roofing membrane installed with the Hydrotech layers? I'm definately going to check out the GreenGrid modules as well.
Anyone else have some green products? Or just some regular old tiling/surface systems?

The project was all new construction. Roof construction was sloped steel decking w/3" rigid insulation and an EPDM roof membrane. The green roof system was put in place on top of that - a root barrier membrane covered by a moisture retention mat covered by gravel fill covered by three inches of soil planted with sedum.
