We moved into a house 3 yrs ago and have had ice dams two of the last three winters when we had heavy snowstorms.No one has been able to diagnose our problem as of yet.We replaced the roof completely after the first incident.We will be adding cellulose insulation to the attic next week to insure we have proper insulation.Our ventilation is good there.We have been told by different people to put in heating cable,pull up the shingles and add ice and water barrier,or remove the gutters.We have no idea what the best course of action would be. Can anyone offer some sound advice on this? Thanks.
