You might want to cut some wedge blocks and attach them to the roof and cut a wider piece of plywood, which overhangs the walls, and attach it to the wedges to create some pitch in order to improve water shedding. Might consider a shingle or two as well. They can often be bought singly. Maybe felt underneath if you happen to have some.
