So, my neighbours an elderly couple have this problem with a corner of their roof possibly missing a gutter or something because when it rains, the rain pours down the side of the pillar and during the winter all of this freezes and hugh chunks of ice hang down the roof as well as creating an ice skating spot in front of their home. I had a roofing company look at it but they said that they would need a new roof as theirs is already sloped and now the rain is being redirected away from the gutters. I was thinking about maybe temporarily installing some kind of corner gutter with downspout to at least try to re-direct the rain water away from the house. Any help would be very appreciated. Any thought on diverters??
