What is the best way to waterproof a deck that is over living space? It’s a very protected deck, but it will be over a living room. We prefer a tiled finish, but want to make sure there is proper ventilation and drainage. The deck is about 6′ by 10′. I have heard of a system that requires torch -on roofing, sleepers and a membrane for drainage, then concrete and tile.
Anyone know about this?

I would prefer EPDM rubber roofing if it were mine. Other than that, the basic system described is fine. This is not a DIY project for most folks tho, IMO

Piffin is right. The reason I don't do sealed decks is because of the liability factor. You want to hire someone that only specializes in sealed decking.
There's nothing like looking up and wondering how those brown water spots got on your ceiling, then wondering how you are ever going to find out where the leak is coming from.
Guess what, if the dude has to come back and fix a leak, he wasn't worth the money you saved.
There is a system with elevated tiles over rubber membrane down the street from me. I'll go take some shots of it and post them plus find out who the manufacturer is.
Check back in a day........

Most interested to hear about the deck down the street. I am designing the house for the homeowners, and they will be getting a professional to do the job. I just need to know I've got it figured out ahead of time, so i can be sure it's sound, and allow enough depth for slope, venting and finishes etc. I'm always concerned about decks over living spaces, but I know it can be done properly with some planning.
look forward to hearing more thoughts.

I'll second the motion for a waterproofing specialist. I've had occasion to sub work to a company that did nothing but waterproof decks. They knew all the materials and all the tricks, and by comparison, carpenters look silly playing with that stuff. Look in the Yeller Pages under 'Waterproofing Contractors'
