Understanding High Temp Ice and Water Shields
What is High Temp Ice and Water Shield?
High temperature ice and water shields are specialized roofing underlayments designed to provide a waterproof barrier that can withstand extreme heat. They are particularly important in preventing leaks from ice dams and heavy rainfall. These products are self-adhering, making them easy to install, and they offer excellent protection against moisture damage.
Importance of High Temperature Resistance
Roofing systems are subjected to various environmental conditions, including high temperatures that can exceed 200°F in some areas. High temp ice and water shields are engineered to maintain their adhesive properties and structural integrity even under these extreme conditions. This ensures that the roofing system remains watertight, reducing the risk of costly repairs down the line.
Applications of High Temp Ice and Water Shields
Residential vs. Commercial Use
High temp ice and water shields are versatile and can be used for both residential and commercial roofing applications. In residential settings, they are often used in areas prone to ice dams, such as sloped roofs. For commercial applications, especially with metal roofs, these shields provide enhanced protection due to their ability to seal around fasteners and resist high temperatures.
Compatibility with Roofing Materials
These underlayments are compatible with a variety of roofing materials, including asphalt shingles, metal, and tile roofs. Each type of shield may have specific compatibility requirements, so it’s essential to check the manufacturer’s recommendations to ensure optimal performance.
Technical Features of High Temp Ice and Water Shields
Material Composition
High temp ice and water shields are typically made from advanced materials such as rubberized asphalt and polymeric films. For example, the GRACE ICE & WATER SHIELD® HT features a proprietary rubberized asphalt adhesive combined with a high-performance polymeric film that offers UV protection. Comparatively, the MetShield HT Underlayment is constructed from SBS modified bitumen with a durable polyethylene top facer.
Adhesive Properties
The adhesive used in these shields is crucial for creating a strong bond with the roof deck. Products like Grip-Rite® ShingleLayment®-HT utilize a butyl adhesive for enhanced performance, ensuring a secure connection that withstands the elements. The inclusion of features like RIPCORD® in some products facilitates easier installation, particularly in detailed areas.
UV Resistance and Exposure Time
Many high temp ice and water shields are designed to withstand UV exposure for extended periods. For instance, Ice & Water Shield® HT can endure UV exposure for up to 120 days, making it suitable for projects that may experience delays during construction.
