Because we have a metal roof, the snow doesn't slowly melt off - it all slides off in great house-shaking chunks. We thought this was fun, last year, but it can be a little destructive too.
Most of our berry cages look like this. Just fine, though buried under almost 3 feet of snow.
And then there is this poor cage, which lives just under the sewing room roof, where all the snow from the second story and the sewing room roof falls off. I hope the plant underneath is okay!
