The answer to 'ridge vent ice dam' is that a ridge vent ice dam is a buildup of ice at the peak of the roof, which can block the ridge vent and prevent proper ventilation. This can lead to moisture buildup, mold, and potential roof damage. Common causes include poor insulation, inadequate ventilation, and extreme cold temperatures.
Symptoms of a ridge vent ice dam include visible ice buildup at the peak of the roof, icicles hanging from the eaves, and water damage or leaks inside the home. Solutions may include improving insulation, clearing the ice dam, and ensuring proper ventilation. In some cases, a professional roofer may need to be called to address more complex issues.
