What's with the Racoons ?

At approximately 1am today I was woken up by what sounded like someone having a party on the roof of the house (quickly checking my schedule on my Pocket PC and SPOT watch I certainly hadn't setup a party) - there was the sound of footsteps running up and down, and something banging on the roof.

I stepped outside and used a torch (flashlight) to shine onto the roof, there was a Racoon trying to remove portions of the roof - sure these critters look cute, but not at 1am with parts of my roof in it's mouth - after an appropriate amount of arm waving, shouting and shining the torch into it's face it ran away... Just wondering whether it's going to be back again tonight...
