With all of the snow we’ve been getting, a lot of people have huge drifts on their roofs, which, if left untreated leads to ice dams. There are several different ways to take care of this problem.
You can install heating wires on the shingles. You can get up there and shovel it of. You can use a blowtorch. Make your wife do it. Let it sit there until it does permanent and costly damage to your structural supports. Or, if you DON’T want to be a man, you can use a roof rake.
