The answer to 'fascia ice dam' is that a fascia ice dam is a buildup of ice that forms on the fascia board, the horizontal board that runs along the lower edge of a roof. This occurs when heat from the home escapes through the roof and melts snow, which then refreezes on the cold fascia board. Fascia ice dams can cause water to back up under the shingles and leak into the home, leading to water damage.
Common causes of fascia ice dams include poor attic insulation, inadequate ventilation, and heat loss through the roof. Symptoms include icicles forming on the fascia, water stains on the interior walls or ceiling, and standing water on the roof. Solutions may involve improving attic insulation, adding roof vents, or installing heat cables on the fascia to melt the ice. If the problem is severe, it's best to call a professional roofer to assess the situation and recommend the appropriate repairs.
