Ice and Water Shield
Ice and water shield is a type of roofing underlayment used to protect a roof from water damage caused by ice dams or wind-driven rain. It is a self-adhesive, waterproof membrane that is applied to the roof deck, typically in the areas where ice dams are most likely to form, such as the eaves and valleys of a roof.
Ice and water shield is made from a rubberized asphalt material that is highly flexible and resistant to water, making it ideal for use in cold climates. When applied correctly, it creates a secondary water barrier that helps to prevent water from entering the roof deck, even if the primary roofing material is damaged or penetrated.
Ice and water shield is typically used in conjunction with other roofing materials, such as asphalt shingles or metal roofing, and is applied directly to the roof deck, under the primary roofing material. It is also available in a range of widths and lengths, making it easy to install, even on complex roof shapes.
Overall, ice and water shield is an important component of a well-designed roofing system, as it provides added protection against water damage caused by ice dams or wind-driven rain, helping to extend the life of the roof and protect the home from water damage.
