Hey Folks - have a question about using the roof of my attached garage as a deck/patio. I did this a few years ago using a product from Sani-Tred, which is basically a liquid rubber that is supposed to be able to hold up to the weather and also made to be walked on. To say the least I have been highly disappointed. It has cracked, gotten moldy, and looks like crap. The stuff was expensive too. I think I spent over $3K using their products. Does anyone have any ideas on what other products would be a good alternative, or best practices on using flat roofs as decks? Thanks in advance!
