"Peel and Stick" waterproof membrane?

Has anyone used any of these products? What would you recommend for a "peel and stick" waterproof membrane on a plywood deck using trex wearing surface ? Here are some web sites that I found.

I need to water proof a deck that is over a first floor room. The deck is the ceiling of the room. The room has drywall and the deck is 3/4" T&G plywood over 2 x 8 joists. The deck is 8' x 30' and is accessed from the second floor of a two story house.

We live in the hight desert of California and average less than 4 inches of rain a year.

I want to have the trex "float" on the membrane without any penetration of the membrane.

No, the Trex HAS to be attached to joists. It will become your worst nitemare if you don't do that!! And the joists that you attach the Trex to have to be secured as well.

Best thing to do is to cover the roof with EDPM, lay your joists (probably 2X4's layed flat, perpendicular to the wall, so water can flow off of the roof) down and caulk the edges to keep water from getting under them. Use a Dow Corning waterproof sealant -- get it at a local glass shop -- anything less will fail. Then screw the Trex to your joists.

If you don't have room to do it exactly that way, forget the deck!
