<p><font face="Helvetica, Arial, sans-serif">I have a boathouse on
my property with a flat roof that, surprisingly. leaks. I would
like to put a deck on the roof, as the structure is strong
enough to support it. However, I am stumped as to the best
material to use to get a durable and waterproof surface that is
walkable. My carpenter suggests rubber membrane, the styrofoam,
then a wood deck, but I have concerns about the weight, plus the
weight of folks on it. As well, maintenance might be an issue.
Duradeck, etc are seem hardly to be green alternatives. Any
ideas, folks?</font></p>
