I'm not trying to brag or anything, but my apartment building has a roof. Yeah, that's right: a roof, right on top of the building. I'll take your high-fives at the end of the post, thanks. Anyway, it's pretty much like any other roof -- keeps the weather out of the interior of the building, mostly tar paper, a few crappy pavers surrounded by planters and a strongly-worded sign from the co-op board reminding residents that leaving the paver-ed area is strictly verboten. Look, it's not a very cool building -- and don't get me started on the inefficient windows in the bedroom -- but I figure that our roof isn't appreciably less cool than most others in the city. Which means that they're less cool by a factor of a thousand than the two new demonstration roofs that recently went on display. The roofs are a collaboration between Town & Gardens landscapers and greenscreen green walls and to say that they are cooler than my roof (or probably yours) is a dramatic understatement.
