Product Summary
Construction and Materials
GAF Materials Corporation, a recognized leader in roofing and weatherization products, offers a robust line of Ice & Water Barrier systems designed to protect your home from the damaging effects of ice dams and water penetration. These underlayment membranes are a critical component of a comprehensive roofing system, providing an extra layer of defense against moisture that can compromise the integrity of your roof deck and the structure of your home.
The construction of GAF's Ice & Water Barrier products typically involves a sophisticated multi-layer design. At the core is a tough, dimensionally stable fiberglass reinforcing mat. This mat provides excellent tear strength and ensures the product lays flat and stays in place, even in challenging weather conditions. This reinforcing layer is then saturated and coated with specially formulated asphaltic compounds.
The proprietary asphaltic coatings are engineered for superior adhesion and waterproofing. They create a tenacious bond to the roof deck, preventing water from migrating underneath, even if shingles are damaged or blown off. The granular surface often found on the top layer of these products is designed to provide excellent walkability for roofing contractors during installation and to offer superior shingle adhesion once the roofing shingles are applied over the barrier.
Key materials and construction features commonly found in GAF's Ice & Water Barrier systems include:
- Reinforcing Scrim: A robust, dimensionally stable fiberglass mat for superior tear resistance and stability.
- Asphaltic Coating: Specially formulated asphaltic compounds provide exceptional waterproofing and adhesion.
- Granular Surface: Enhances walkability for installers and promotes shingle adhesion.
- Self-Adhering Technology (in some models): Select products feature a full adhesion system, often with a removable release film, for enhanced holding power and ease of installation without the need for additional fasteners in the adhered area. This technology creates an immediate watertight seal.
- High-Temperature Resistance: Materials are selected to withstand extreme temperature fluctuations without degradation, ensuring long-term performance.
- Slip-Resistant Texture: Provides a safer working surface for roofing professionals during installation.
GAF's commitment to innovation is evident in the development of advanced Ice & Water Barrier products. These membranes are meticulously engineered to meet and exceed industry standards for water holdout and durability. The result is a dependable barrier that safeguards your home against leaks, rot, and the costly repairs associated with water damage, particularly in vulnerable areas like eaves, valleys, and around penetrations.

Options-Styles
GAF Materials Corporation offers a range of high-quality ice and water barrier products designed to protect your home from the damaging effects of ice dams and wind-driven rain. These underlayment products provide an essential layer of defense for your roof system, particularly in vulnerable areas.
The primary purpose of GAF's ice and water barriers is to create a robust seal against moisture intrusion. They are engineered to adhere securely to the roof deck, forming a watertight membrane that prevents water from seeping under shingles and causing rot, mold, or structural damage. This is especially critical along eaves, valleys, rakes, and around penetrations like chimneys and skylights.
GAF provides several product options within their ice and water barrier category, each offering distinct features and benefits to suit various project needs:
- RoofRunner® Waterproofing Underlayment: While not strictly an ice and water barrier in the same category as dedicated self-adhering membranes, RoofRunner is a synthetic underlayment that provides a protective layer against water. It's often used as a secondary water barrier and can contribute to the overall weather resistance of the roofing system. Its strength and durability offer reliable protection against wind-driven rain.
- StormGuard® Chipped-Surface Waterproofing Shingles: These shingles are designed with a granulated surface that provides enhanced grip and protection against wind uplift. While they are shingles, their construction incorporates waterproofing capabilities that offer an added layer of defense in critical areas, working in conjunction with traditional underlayments.
- SureGuard® Waterproofing Underlayment: This is a self-adhering waterproofing underlayment that offers superior protection against ice dams and wind-driven rain. SureGuard forms a tenacious bond to the roof deck, creating a continuous waterproof barrier. Its design is intended for easy installation and long-lasting performance.
- Tiger Paw® Specialty DryGuard® Underlayment: Tiger Paw Specialty DryGuard is a high-performance synthetic underlayment. It is engineered to be durable and resistant to moisture, providing excellent protection against water intrusion. Its robust construction makes it suitable for various roof pitches and challenging weather conditions.
- Underlayment Options: GAF also offers a variety of other underlayment products, some of which may include asphalt-saturated felt and synthetic alternatives, designed to work as part of a comprehensive roofing system. The specific ice and water protection capabilities will vary based on the product chosen.
The installation of GAF ice and water barriers is typically straightforward, with many products featuring a self-adhering design that simplifies the application process. This self-adhering technology ensures a strong, reliable seal without the need for mechanical fasteners in certain applications, reducing the risk of leaks through fastener holes.
When selecting an ice and water barrier, consider factors such as your local climate, the specific design of your roof, and the overall warranty and performance expectations for your roofing system. GAF's comprehensive line of underlayment and waterproofing products provides contractors and homeowners with reliable solutions to safeguard structures from the elements.
