A few years ago we put a standing-seam metal roof on our house. They are more durable than asphalt shingles and do not accumulate snow or form ice dams. Well, they do accumulate snow during colder periods, like the last week, but when it gets warm (like today), that snow slides slowly off, often in huge sheets. Whump! it hits the ground. When Pam re-did the decking, a few years ago, she had the clever idea to make a section of the deck fold up against the house, allowing the snow to fall through to the ground below. I’ve written about this before – but today I captured a brief video for you. These are small, compared to what they can often be! The whole house shakes several times every minute, as this snow load drops off.
