[GBlist] low tech green roof?

["Alan Abrams" <awabrams@starpower.net>]

this is a request for *practical* information on
detailing a green roof.  Does anyone have first hand
experience building green roofs with commonly
available, more or less conventional building
materials?  I've looked at a few websites on the
subject; they seem to require sophisticated membranes
and drainage matts--I think it would be beneficial to
be able to build with, for example, torch applied
modified bitumen and ordinary foundation wall drainage
matts.  Low-tech is good, no?
