The warm weather causes the snow to start to shift from the metal roofs. It starts with often no warning -- there is a sudden roar, and an avalanche, and the snow comes tumbling down.
We are keeping an eye on the garage snow-load, which is gradually working its way towards terra firma. The big Rec Barn shed its snow with a roar on last Friday. The garage is just hanging on.
I have certainly seen that many a time!
