Ice and water membrane is a self-adhering waterproof barrier installed in high-risk roof areas such as valleys, eaves, and penetrations. It prevents water infiltration caused by ice dams, heavy rainfall, and wind-driven moisture. In colder and wet regions like British Columbia, this membrane is essential for protecting roof decks and ensuring long-term durability. It seals tightly around nails and fasteners, creating a highly effective waterproof layer.
