Looks like something fell out of the sky straight onto the roof? Maybe a grand piano? Or and Anvil? On a similar vein about 7 years ago I used to have a VW Caddy. My Dad drove it through a height restriction at the dump and ripped the roof half off. I sold it on Ebay two weeks later for £700.00 and the polish bloke who bought it was over moon and said it was a complete bargain!
