I am very interested. Please do!
Here ya go (don't forget that the framing must be twice as strong as for a shingle roof):
green roof pitch: 1.5 in 12, no more than 1 in 5.
Roof planking: 2 inch tongue-and-groove
waterproofing membrane directly over planking
extruded polystyrene insulation over waterproofing membrane (optional)
6 mil black polyethylene plastic over insulation (if insulation is used)
composite drainage matting over black plastic (cotton towels from the thrift store work well)
7-8 inches of soil
A layer of hay bales can also be used to cover the roof. Good insulation, and they will eventually turn into a living roof.
