We've always had trouble with snow falling off the roof onto the porch making it a slippery mess. And if it snows a lot overnight there gets to be such a pile that we can't open the door.
Dan found and installed this snow fence on the roof this past fall. It works great.
And for the snow that lands on the porch, for Christmas our daughter gave us a heated mat. It has a remote control inside to turn it on and off.
Two winter aids I've been meaning to share.
