Hi all, We're in a rooftop apartment here in Burnaby that's got full south and west exposure, and we want to use the 18 x 16.5' empty space of the roof next to our deck for something a little greener than the tar-and-gravel that's currently there. We were thinking of setting up some sort of lawn arrangement up there, using an elevated base (perhaps shipping pallets as a base), then landscaping cloth, then a layer of topsoil a few inches thick, and then laying sod. Does this sound feasible? Or are we right out to lunch? Information on setting up rooftop gardens seems to be relatively hard to come by - most of it seems to be geared towards container gardening, which I've got down pat. Thanks for any suggestions you might have!
