My house, like most other houses has a tin/aluminium roof, and lately there has been a lot of banging and crashing from it, like elephants walking on it. It's the worst when you're upstairs. We've been trying to figure out what it is, because we don't have an attic or anything that the cats could get into to cause chaos in.
It was only just now when I saw my neighbour throwing footballs onto the roof and over the house and onto the road that it clicked what it was...
