Oh, yeah. I have metal roofing everywhere but the gazebo, which nearly collapsed under the snow load a couple of years ago. Got a snow rake and learned the one lesson you always learn the hard way with them: do not stand directly underneath the snow mass you’re trying to bring down. I had approximately half a second to reflect on how stupid I am before the snow impacted... :-(
Another thing: use nowhere even close to where the power lines enter the house . . . even if you think you are a safe distance away. The natural bowing in the aluminum pipe extensions plus the stress put on the rake in moving snow plus the changing winds plus your tiring arms and wrists can give the thing AMAZING recoil.
Yeah, you will leave an arc of snow on the roof in that vicinity. But the risks of getting it off just aren't worth it.
