woodshed damaged in birch tree suicide attack

The birch, long dead, had been biding its time. Last night, it struck:

One roof board broke, and a 1" hole was ripped through the ridge cap. And the metal roof looks a little crumpled. Since all that damage effects the function of the woodshed not one bit, I'm going to do nothing about it (except clean up the birch).

Nice try, forest. But you're going to have to do better than that if you want to stop me from feeding you into my stove.
