The gutter helmet people sell a heavier duty solution for about $1000 on my modest sized home, but that wouldn't include the electrical hook-up.
However, I have enough electrical know-how to do that part myself.
Used to live in CO mountains. Roof ice dams were very common.
Guys would climb up on an icy roof, sometime two or three stories up, and flail away at the ice with an ax or sledgehammer. And, yes, some tried the torch method.
Results were often not pretty.
