Not really. Currently (my visualization is that) there is nothing to attach it to. There is ice and water. After you get rid of those, the problem is gone, and a snow rake should prevent re-ocurrence. Getting rid of it is the trick. Also if the problem is (as he says) the gutter, rather than the edge of the roof, heat tape would make it worse rather than better.

Not to mention the horror of the idea of heating the whole outdoors with electricity...
