2 things you can do to fight ice dams
1. Clean leaves, sticks, and debris from gutters and down spouts each fall. This basic maintenance will allow melting snow to flow into the gutters and down the spouts as intended.
2. Remove the snow regularly from the roof with your Roof Snow Scraper. By keeping the snow load to a minimum, you will reduce the chances of an ice dam forming. You don’t have to clean the entire roof area, mainly the bottom edge of the roof, about 3 or 4 feet wide along the eave edge. After you have cleaned off the bottom edge of the roof the snow will melt off when the sun comes out, this will keep the eave edge free of ice.
Ice dams are only a symptom of the problem. The real problem is poor ventilation and insulation.
