Well, the type of roofing in that Craigslist photo is going to be much more thin than the corrugated you're looking for. I'd be very hesitant to use any metal roofing with flat parts to hold back dirt. All the curves in corrugated lend strength. Corrugated WILL bulge out a bit with dirt behind it, but it's less noticeable than with a flat panel. Mine are about 36" high, which is a significant amount of dirt to be holding back.
