My mum n dad have a garage attached to their house. It's rather long, since
the guy who built it (previous owner did it himself, we're told) also
extended the kitchen sideways at the same time. So, it's the same length as
the house (25 feet or so). Neighbour says he used pretty much any bits of
chipboard he could find. There seems to be no incline, since water tends to
sit it pools on top. It has a few leaks, and has once caused water to pour
out of a light switch in the kitchen. I patched that one up, but we're
thinking it would be nice to do something so that we can just forget about
it in future. Having it properly replaced is out of the question - the
money will never be available in their lifetimes. I was wondering if I
could cover it all up with some corrugated sheets, making sure they slope
down to the back, where there is already a gutter. Is this a reasonable
thing to do, or just plain bonkers?
