I am trying to do my best to not relive the nightmare of last winter's ice dam issues. I have talked to a number of people and researched this topic endlessly. I understand the concept that if the attic space is close to the same temperature as the outside, this would eliminate the problem because it's the warm attic that is creating all of this. The most common answers to this issue is to make sure that the warm air from the living space is not getting into the attic, which is done through insulation. There also needs to be a ridge vent and soffit ventilation in place to keep the attic cold. One of my problems was that my house was built in 1983 and soffit vents were never installed. That will be done before winter. I also want to make sure that I have the correct amount of attic floor insulation in place. My concern is that I use my attic for storage and floor insulation is not supposed to be compressed. Has anyone been in this situation before and what was your solution. Thank you..
