The slope of the roof does matter. Min=6"/foot, max=about 1.5'/foot of run. I would seal the roof and add a layer of felt tar paper. No sand needed, keep it light and get a soil with a more porous and light constitution. There may not be a lot of drainage needed, just depends upon your rain patters.
