The snow came off the garage roof at the back - as you can see the pieces were massive. I was worried about the window but it was ok. The roof is so sloped that it slid out from the house instead of just down. Thank goodness. But that is bad news for the wood shed across from the garage. I have a feeling that there will be some adjusting to do to it after the snow comes down on that side. I am checking every couple of minutes this afternoon for it to come down. I can just see it from the window at the top of the stairs here. Just checked - not yet.
