I can tell you're not from the north. Snowy days aren't dark and cloudy. You'll wear sunglasses sometimes. Dark roofs absolutely help melt snow. The snow starts melting near the gutters and then climbs upward. The snow also sublimates. When it gets really cold, clouds can't form so there are a lot of bright days without a cloud in the sky.
