Ice Dam Removal Columbus Ohio
An ice dam is ice buildup that forms at the edge of your roof, usually above the gutters. Once it has formed on your roof, the water then backs up behind the ice dam and creates a pool of water. This pool of water can then leak under the shingles and enter into your house causing damage to walls, ceilings, insulation, and other areas.
Ice dams are typically caused by heavy snowfall and improper ventilation and/or insulation of your attic. This results in slightly warmer areas in the top of your attic which causes the snow to melt, even though the outside temperature may still be well below freezing. When the accumulated snow on your roof starts to melt, it runs down the roof underneath the existing snow until it reaches a much colder section (like in the gutters) and then it freezes again. This process of thawing and refreezing is what causes an ice dam.
Cleaning the gutters on your home can help prevent ice dams from forming but they can still occur if the conditions are right. Your gutters will be just as cold as the outside temperature or they could have frozen debris. So even if you don’t have a soffit for the water to refreeze in, the melted water will most likely refreeze when flowing into the gutters.
