We recently bought a house, and they had a deck over the garage. Unfortunately, they covered the deck in tile with no waterproofing underneath AND the deck slopes toward the house. It's a mess, and we're planning on redoing the framing as they did quite the crazy DIY frame job and the only solution is to tear it down.
However, what I'm not sure about is what the best floor for the decking could be. We could do the EPDM rubber membrane over deck, but that's not very attractive. I'd appreciate any suggestions.
