I'm wanting to make my garage water-tight. Part of that will be having it re-roofed, but I'm struggling to figure out how to get a good seal around the door at the rear of the garage. The problem is that the passage is too narrow for a standard door, measuring just 550mm.
I've attached a picture to illustrate the problem. Currently there's a wooden "gate" hinged on one side that bolts closed against the wall of the house where it hits. This arrangement leaves a gap between the roof of the garage and the door (in red). Any ideas what I could do? Ideally I want a proper door that seals closed against a frame. The pillar supporting the outer wall by the gate is just a single brick.
