A resident from West Chicago dared to challenge our “go ahead, ask us anything” motto. This question has been asked too many time and I thought it’d be great to share with our followers. Please understand all answers are based off the experience of a general contractor. I’ve been an acting roofing contractor and have been doing roof replacements for many years. If anyone finds my answers untrue, please inform us immediately.
We do not, but I do know the problem and have solutions. Usually ice dams occur due to improper air flow in your attic. Attics are supposed to be 5 degrees (give or take) difference compared to the outside temperature. When there is snow on your roof, the heat from your attic is melting the snow. The melted water turns into ice once it reaches the gutters. This cycle will continue, and eventually, ice will get backed under all your roof underlayments (shingle/ice water/felt). That ice will melt and water will find its way into your home.
Proper solution- You either do not have enough ventilation in your attic or the insulation in the attic is plugging the soffit vents. You’ll need to crawl into your attic with a flash light and check if insulation is plugging the soffit. Use a tool to bring out as much insulation away from the soffit area. Do this along all soffit surroundings.
Alternative solution– Purchase a heat coil at Home Depot/Lowes. When winter comes, line the heat coil inside the gutters and ice dams will no longer occur.
