This is often a question for the area. When considering ice damming one has to be considerate of the snow fall and freezing conditions we can have here in Pagosa Springs. Our philosophy on the matter falls back to the simplicity of eliminating places for damming to occur. A simple Gable roof eliminates the locations for this to happen. Peaks into valleys and having areas where multiple roof lines dump onto one location of the roof is a prime place for ice damming to occur. You also want to consider having your roof line adjusted to where you do not have snow loads dumping in front of your garage or walkways. There are many ways you can re-design a roof to maximize looks while also taking these things into consideration.
