He can only use tin. Get some barn siding tin and use neoprene washer

running foot. That roof should cost $10 with the screws. A rural
lumberyard may have a bent or dented sheet with a usable portion of the
sheet remaining.

To be honest, I'd say find a big ol' fridge at a junkyard (or via
freecycle) and cut down one of the flat side panels.

Or put an angled roof on the thing...
