Yes. I clean up under the skylight to avoid an ice dam and any leaks.Been using one for years. We are in the snow belt of Ontario. My house doesn't have a steep pitch, so I worry about ice dams building up. It's not hard to do if you do it while the snow is still nice and fluffy.
I think my next roof might be metal as well.I'll need shingles in the next couple years. I'm going to use sheet metal instead. I'll be long dead before it ever needs to be placed. No leaks, no worries about hail, snow slides off and it will never moss up.
