We have a screened porch with a sloping low asphalt roof off the back of our house. I have limited garden space in our small yard. I was wondering if I could put perforated bags of garden/potting soil along the edge of the roof and plant vining vegetables like cukes or tomatoes in them to form a curtain of vegetables that would hang down off roof, kind of like the upside down planters, or like the pioneers who planted gardens on the roof of their sod houses. I could water with hose and perhaps place the perforated bags on skids for better drainage against roof. Do you think this would work?

I think you will rot the roof unless the design is planned very well.
I also think weight will be an issue on a porch roof.

I agree that the structure needs to be able to handle the load, but than I'n sure you will not exceed any snow loads.
I'd be more concerned with the added heat coming off the roof. Otherwise, I say give it a try. Who knows, maybe you'll have your own infomercial someday.
