Love the setting - great for sure.

If the association doesn't care what you do, I'd look into wood slats on top of the existing surface, just have it filled and patched first to ensure watertight protection. Things to check include weight (anything added to a roof adds weight and this can be a real problem if not investigated), flashing details at edges, drainage (perfectly flat, horizontal decks are a BAD idea - need to have drainage min. 1/8" per 1'-0", preferably 1/4" per 1'-0"), etc. When I get back that way next if you're around I'd love to check it out for you. Maybe I could look into working something up if you want - I'm not doing much else these days and it'd be a good design exercise... Lemmee know.
