Welcome to our forum.
I failed to mention that this is a 2nd home, so I'm not always there to sweep the snow off as soon as it falls. Wish we had a caretaker...but no! The tarp idea may certainly be worth a try, thanks. Any other ideas?
Tarp sounds good for a second home, I would hate to remove it and reinstall it each time, for a weekend home that wouldn't be so bad.
I would suggest taking a closer look at the cover. If you are getting ice, that means heat is coming through the cover which is a problem in and of itself. An "Insulating Cover" is exactly that and should not be melting snow to turn into ice.
