- Code Compliance and Risk Reduction: Protection against ice dams is required by most building codes2 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” on the map. In Southern/warmer climates, leak barriers provide critical protection against wind-driven rain.
- Strong Protection: Guards vulnerable areas of your roof including eaves and rakes, in valleys, around chimneys and skylights, and more.
- Dependable: Self-seals around nails to help avoid leaks.
- Fiberglass-reinforced: Helps resist buckling and wrinkling that can detract from the look of your finished roof.
- Split-back Release Film: Peels off in layers for fast installation.
- Convenient: 1.5 square (150 ft.2 [13.9 m2]) and 2.0 square (200 ft.2 [18.58 m2]) roll - excludes laps.
