The snow in my Arkansas coffee can test has melted and the depth has been measured - 8" of water, which works out to a snow load of 41.6 psf. This is higher than my estimate based on my 12" snow cube, I am sure because my cube was higher up in the pack and did not account for the more densely packed snow at the bottom. Back at it again today, before there's ever a chance of that getting rain-soaked.
Any fabric covered barns in trouble?? Mine has done alright so far. Truss type 138ft x 83ft by 55ft high
You have my respect...That is hard work that needs to be done. It becomes a priority. It is all about keeping things safe.
Your pictures look familiar to me. That is what my garage looked like when I decided to get up there and clear it. Fact is, the bottom half had turned to ice. I couldn't even chip at it...it was simply to late. A week a 2 later...Down she came.!! It felt like I had just gone through a fire.
But, I learned a big lesson. Get after it every storm.
Best of luck to you.
