Installing rooftop garden?
I live in SF and have a flat roof. I’ve wanted to garden in my (small) yard, but I don’t get a ton of sunlight due to nearby shady trees. It recently occurred to me I could maybe install a garden on my significantly-more-sizable roof, which would also provide much-needed cooling insulation during our increasingly hot summers. I looked a little at local regulations and it seems it might be possible for me (I also have a spot in my house that would perfectly accommodate a stairway up to and through the roof). I’m wondering how (insanely?) expensive this might be and also if anyone with experience has pros or cons to share.
thanks for any input!
