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.

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.

Product Summary
Construction and Materials
This product falls within the Weatherization & Flashing category, specifically as an Ice & Water Barrier and Air & Vapor Barrier. GCP Applied Technologies, the manufacturer, is known for providing advanced building material solutions.
While specific construction details and materials for individual products within this category are often proprietary and vary based on the exact product line, the general principles and common materials for such barriers can be described.
Construction Overview:
- These barriers are typically multi-layered systems designed to prevent the ingress of water and air into the building envelope while also controlling vapor diffusion.
- The primary function is to create a continuous, sealed membrane around the building's exterior, particularly critical in areas prone to ice damming and significant temperature differentials.
Common Materials Used:
- Bitumen-Modified Asphalt: Often forms the core of these membranes. This material provides excellent waterproofing properties and adhesion. The asphalt is modified with polymers (like SBS or APP) to improve its flexibility, elongation, and performance over a range of temperatures.
- Reinforcement Scrim: A layer of polyester or fiberglass fabric is commonly embedded within the asphalt layers. This reinforcement adds tensile strength, dimensional stability, and puncture resistance to the membrane, ensuring its integrity during installation and over its lifespan.
- Release Liner: A disposable protective film (often silicone-coated paper or polyethylene) is applied to the adhesive side of the membrane to prevent premature sticking and allow for easy handling and positioning during installation. This liner is removed just before the membrane is applied.
- Adhesive Layer: The underside of the membrane is coated with a high-tack adhesive, allowing it to bond securely to the substrate (e.g., roof deck, wall sheathing). This self-adhering quality is crucial for creating a continuous, watertight, and airtight seal without the need for torches or adhesives in many applications.
- Surface Granules/Facings: Some products may have a protective top surface, such as mineral granules or a polyethylene film, to protect the membrane from UV exposure and physical damage during subsequent construction phases.
The specific composition and layering are engineered to meet stringent performance requirements for water resistance, air infiltration control, and vapor permeance, contributing to energy efficiency and the longevity of the building structure.
