  Gennaro,

  Add "eco material" to that description and it becomes an old quest of mine. 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.

  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.

  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?)

  There is a group called Brooklyn Bridge Forest ( http://www.brooklynbridgeforest.com/) 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.)

    Hello,
    Can anyone suggest a lightweight non-combustible deck material for a roof deck?
    In New York a brownstone has an average flat roof of 700sq.ft. The law only allows 20% of it to be covered with combustible decking, which isn't much of a deck. Yet the non-combustible decking is too heavy for the old roofs.
    Suggestion?
