I have a green roof on my house, but some how I don't think you mean moss covered tiles
But if you are considering a green roof you really need to have strong joists, when I built my extension 8 X 2 joists that size was required to take the weight of any potential snow fall so I think the minimum thickness of joists would be 6X2 and I would think it would also require 4 X 4 uprights or a metal framed shed and another possibility is a small shipping container, as for plants, you can buy rolls of low growing sedum or you could buy some suitable sedum seeds and sow them in shallow trays
