I don't think it's a big concern We dig up our garden and start over
from scratch far more often than we reroof our house. We've been in our
house for 21 years - we put a new roof on 2-3 years in, and we literally
haven't touched it since except, I think, to replace a single shingle
that blew off in a high wind a few years ago.

When you need a new roof under a roof-top garden, you dig up the garden,
put all the dirt in a dumpster, put in a new roof, put all the dirt
back, and start planting again. If that happens once every 20 years,
OK, then. Here in metro NYC, you'd just time it to be at one end or the
other of the growing season.
