I have a roof/deck over my garage and I want to install the Gorilla Deck watertight decking. Does anyone have any comments? I live in a snow prone area.

Handle the extra weight.

With less egress for water you may get pooling and get extra weight on that deck and your deck may end up in your garage.So insure your roof can handle the weight and make sure you have proper drainage.

Thanks, Handyman. Do you think 2'x10' at 16" centers over a 16' span with a .5/12 pitch will stand up ? Also, my wife asked about any possibility of water getting stagnate and smelling in the drain passages. Anyone have any answers?
