I'm in cold northern Alberta Canada and when it snows we have a major drift on our lower shed roof blown off the higher gable roof. This drift piles behind the gable and adds a lot of weight to the shed roof. I have been thinking of ways mother nature could work for me to undo this situation. Have you seen the air spoilers on say the back of a school bus or some cars? These are here to clear the back window of debris left in the vortex while traveling down the road. I was thinking of hanging something similar off the higher gable roof fascia pointing down to the shed roof to act as a wind disturber to send those nasty snow particles on there way to the nabours to plug up his roof. Would any of you have ideas how it may work. I might build a small model and put in my wind exposed yard . That would save me climbing on a slippery tin roof to change my designs when they don't work.

Thanks Greg
