Used to live in big snow country.
Most people had these big alumnimum rake things that were used to rake show off the eaves. Had to get it before it melted and refroze, and in a really big snowfall you’d have to pull the show off several times. But you could get back on the eaves about four feet.
Potentially an excellent way to electrocute yourself, BTW.
I have a snow rake as well:
The one I have is made and sold by a company based in Minnesota. It costs me about $80 with two optional extensions.
It is a bit of a balancing act: You definitely want to use it on the big snows (8" plus) but need to be careful about overusing it on the smaller snows (less than 4") as you run the risk of scraping shingles along with the snow.
I NEVER dig deep. If you run into any resistance, ease off immediately. I always rake as is I intend to leave at least 3/4" on the roof. Here in SW Pennsylvania with a NORMAL winter and dark roof tiles, the sun will help out with the balance anyway and leave you with a thin coating of ice to protect your shingles from future rake jobs.
No, they have the tapes that are made just for eaves. No chance of electrocution at all. Problem is they last just a few years, and the water drips and will freeze below.
