The answer to 'fascia ice dams' is that fascia ice dams are a common roofing problem caused by improper insulation and ventilation in the attic. They occur when heat from the attic melts snow on the roof, causing water to refreeze on the colder fascia boards at the roof's edge. This can lead to leaks, water damage, and even structural issues.
Symptoms of fascia ice dams include visible ice buildup on the fascia, icicles hanging from the roof, and water stains or damage on the interior walls or ceilings. To prevent and fix fascia ice dams, it's important to ensure proper attic insulation and ventilation, as well as proper roof drainage. In some cases, homeowners may be able to address minor issues themselves, but larger or more complex problems may require the expertise of a professional roofing contractor.
