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!
60 mil vinyl decking – brand names include Duradek, Tuffdeck, etc.

I’ve got two decks that were built over my garages flat roofs. I can summarize my advice on one word… don’t. Well, not quite don’t do it at all, but don’t walk directly on a flat roof covering. It will sag, the covering will crack and then you’re in a world of hurt. I ended up having to rebuild one entire deck/roof with a proper slope, cover it with a waterproof membrane (EPDM) and then lay tile over it. The other one will have to be rebuilt soon as well. You can also install raised decking to protect the membrane.
I learned the hard way that the so called tough membranes aren’t.

We’ve used dec-k-ing brand with good luck, maybe look into this before throwing in the towel.deedub35 wrote:

I hear you on not doing it in the first place. It’s such a waste of space, and made for a perfect spot to put an outdoor living area. When we did ours, we incorporated a slight slope. I probably should have went with the membrane like duradek, but I was concerned with the seams.
Thanks for the advice and welcoming everyone!
