The answer to 'drip edge ice dams' is that drip edge is an important roofing component that can help prevent ice dams from forming. Ice dams occur when melting snow refreezes at the edge of the roof, causing a buildup of ice that can lead to water damage. Proper installation of drip edge, along with good attic insulation and ventilation, can help mitigate this issue.
Drip edge is a metal flashing installed along the eaves and rakes of a roof. It directs water off the roof and away from the fascia and siding, preventing water from seeping back under the shingles and into the home. Without drip edge, melting snow and ice can accumulate and freeze, leading to ice dams that can cause leaks and damage.
