<p>Thank you! I'm a Canuck, so hoping that they're also here. Any
brand names you can think if?</p>

<p><span style="font-family:Helvetica">I appreciate your
perspective. I had a rooftop deck at my last house and
used it a lot, so am pretty certain that this one will
get used. I too, hate the thought of vinyl, but it seems
that it's the simplest (and probably the least resource
intensive) response and will address the pressing
issue...the leaking roof. Just wish there was an
alternative to vinyl for the decking that would be as
waterproof and durable.</span><o:p></o:p></p>

sheet). Every roof supply company has the same basic
system – can look at soprema. Will run about 5 to 8
can per square foot in cost depending on local
contractors and size of roof/ details etc. That is a
current flat roof – not a vinyl deck – vinyl deck will
be comparable and probably simpler.</span><o:p></o:p></p>

roofing weight is minimal in itself as most roofs
would carry at least 10llbs per foot for dead load
(sheathing, ceiling drywall, roofing) – a wood deck
added on top would add about 15lbs per sq. ft. dead
load extra so you would need to look at the framing
and see if it meets current environmental load
requirements (things have changed) and if that could
be added. Carpenters love to make decks as they get to
rebuild them 10 years later</span><o:p></o:p></p>

finishes and replacement is better than replacing a

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?</span><o:p></o:p></p>
