Roof snow removal, a topic near and dear to my heart !!! I am trying to find a way to get my new tracked rig up on the roof. Barring that it is just one shovel full at a time. I have +40 in the forecast but with rain. The information I have been able to find indicates that nice dry snow is only about 3# per square foot, wet snow goes to 21# per sq., foot and ice is around 50# sq., foot.
Being almost as old as I you know about "canaries in the coal mine" My canary is the old barn that was here when I bought the place, it was build by a committee, none of the members had any idea about construction, and is is by guess and by gosh, mostly 2"X4", and as far as I know it has been here for around 30 years, and the roof never shoveled off during that time, it is still standing.
