Trees, gravity, why?

[lizvogel]

During one of the ice storms this past winter, the big tree that visually separates us from the neighbors went over, ending up propped on the woodshed. We didn't want to lose the tree, so we figured we'd see if it survived the process. It's been leafing out with great enthusiasm this spring, better than it has for a while, and the woodshed seemed willing to bear the weight, so yay.

I just looked out, and the woodshed roof has crumpled.

Anybody have any clever ideas for propping up a very large tree? I realize the standard response is to cut down the tree and plant something new, but I don't want to be staring into the neighbor's upstairs windows for the next twenty years.
