Green roofs: what's the verdict?
I'm intrigued by the idea but see several obvious problems: 1) leaks, 2) expense, 3) maintenance (weeding etc.), as well as a less tangible but possibly significant issue: 4) prospective home buyers viewing a green roof as a liability (we plan to be in the house for a long time, but plans can change.)
The project in question is about 350 sf. I suppose you could look at the small scope a couple of ways: it's small and therefore more doable, with less at risk; or, it's so small as to be hardly worth the bother. Mostly I'm drawn by the romance of it, inspired in part by childhood visits to Scandinavia. Plus, a green roof would look nicer from the second floor than would a conventional flat roof. The rational part of me says, Why ask for trouble?
What is your experience? How would you advise a client? What resources are available?
