The roof garden is 10x16 planted with sedum. It took a lot of research to figure ot how to. It calcs at 6,700 lb.s wet so I needed to double up on rafters and collar ties first. Then secure the garden frame to keep the whole thing from sliding off. Then, layers of pond liner, J drain mat, root filter then half inch coconut fiber mat for soil filter. Grid the whole thing with 1by every 20 inches to prevent landslide and irrigate with pop up micro's tied to my timer. The planting medium is half Perlite, half peat moss. 2yd.s in total. I set up scaffolding to work up there since it's a so sloped. 52 flats of sedum succulent. Had I known it would be such a major project I might have rethought it but we love it now. Next year, the other half of the garage roof we like it so much. I'm in Napa, CA where it's easy to grow anything. I've had hot air balloons come down for a closer look.
