A couple comments, which sound hard-hearted:
- I suspect many of the roofs which succumbed to the snow load were on buildings erected during the last half of the last century. I doubt either the old-old-fashioned barn on my childhood farm, or the old-fashioned hip-roofed barn which was the standard when I was born would have suffered so. Their roofs were steeper in pitch than the more modern barns I've seen.
- I'm not sure why FSA should be involved. Surely the farmers were carrying insurance on buildings and herd. If they had insurance and the insurance covered barn collapses because of snow, FSA should not be involved.
