I guess I could and maybe David Bergmen knows more but I do know that right now the only things allowed are concrete and metal. They recently said Ipe is no good. That gives me a pretty good idea of what will work.<div><br clear="all">

Are you talking about something to sit directly on the "real" roof? About the best I could come up with when I last tackled the question was lightweight concrete roof pavers -- not all that eco though maybe there are some made with flyash.<br>
<br>In terms of wood, NYC used to accept Ipe, but I heard a rumor they stopped when the fire rating claims didn't prove out. And, of course, there was the rainforest sourcing issue.<br><br>I've looked for fire-rated recycled plastic lumber from time to time, but have not yet found any. (Tim V-K: any updates you've heard of?)<br>
<br>There is a group called Brooklyn Bridge Forest (<a href="http://www.brooklynbridgeforest.com/" target="_blank"><span> </span>http://www.brooklynbridgeforest.com/</a>) that is trying to set up a sustainable source for greenheart for maintaining the Brooklyn Bridge. I'm not sure what kind of fire rating greenheart does or doesn't have. (According to one site I just googled, it carries a "high/medium" rating.)<br>
