Amazing that u-6leaped so much....but mores in that there is nary a peep about it from the “experts”.
Thanks. I only got a cursory look at the TV/Fox take on his. Then, living in NE, I had to get up on a ladder to fight ice damming. If anyone cares, the best thing I've found is a compressor driven air-hammer with a muffler shearing tip. It makes the ice spall and fall off. The only risk is that you might chisel your shingles, so it takes some touch.
