• Code Compliance and Risk Reduction: Protection against ice dams is required by most building codes at eaves wherever the January average temperature is 25°F (-4°C) or lower or where there is a possibility of ice forming in the eaves — i.e., the area labeled “North”.  In Southern/warmer climates, leak barriers provide critical protection against wind-driven rain.
