On a steep slope, yes, but on lower roof slopes the sliding glaciers have great destructive potential. I've seen many cases where people upgraded their asphalt shingles to a metal roof without considering this, resulting in having to spend additional money on repairs and then snow stops, and I've seen many failed snow stops because those systems need to be properly engineered to withstand the great forces involved.

On a low slope in snowy areas high grade asphalt shingles or modified bitumen roll are a better investment.
