Several years ago we had a lot of accumulation of wet snow and roofs on buildings were caving in and I was concerned about the motorhome roof also. I had 3 feet of wet snow and decided to shovel it off just to be safe. In the process I cracked both air-conditioning covers, trying to remove the snow. So knowing what I know now I would just leave the snow alone, your app to do more damage than good. The only time I would remove it is if I decided to travel, I would not want the snow coming off the roof on a car in back of me.
