Product Summary
For a roof to last, your roofing system must include protection from wind-driven rain. This is accomplished by installing waterproofing underlayment directly beneath the shingles. WeatherLock® Series self-adhesive water-proofing underlayment is perfect for both new construction and reroofing projects. In addition to protecting the roof deck from damage from ice dams and wind-driven rain, WeatherLock should also be used on areas of the roof where water has a tendency to collect or flow. Valleys, vents, chimneys and skylights are examples of where WeatherLock Series underlayment should be considered.
Construction and Materials
Owens Corning offers a range of underlayment products designed to provide a critical secondary barrier against water infiltration beneath primary roofing materials. These underlayments are engineered to work in conjunction with shingles and other roofing systems, offering enhanced protection and longevity for the roof deck and building structure.
The construction of Owens Corning underlayments typically involves a durable reinforcing mat or fabric, which is then saturated and/or coated with specific asphalt formulations. This construction provides both strength and water-resistant properties. The specific materials and manufacturing processes vary depending on the product type, with options designed for different climates, exposure levels, and installation methods.
Key materials commonly found in Owens Corning underlayments include:
- Reinforcing Scrim/Mat: Often made from polyester or fiberglass, this provides tensile strength and dimensional stability, preventing tearing and stretching during installation and under roof stress.
- Asphaltic Coating: Specially formulated asphalt provides the primary waterproofing layer. This coating is designed for flexibility, adhesion, and resistance to degradation from UV exposure and temperature fluctuations.
- Mineral Granules (on some products): Some underlayments may incorporate mineral granules on the surface to improve slip resistance for installers and provide additional UV protection.
- Surface Treatments: Proprietary treatments can be applied to enhance grip and facilitate overlap sealing during installation.
Owens Corning offers several types of underlayment solutions, each with specific characteristics:
- Synthetic Underlayments: These are engineered products that utilize advanced polymers and reinforcing fabrics. They are known for being lightweight, strong, and resistant to moisture and rot. Their construction often involves multiple layers of polymeric film and woven or non-woven reinforcing materials.
- Felt Underlayments: Traditionally made from asphalt-saturated felt, these underlayments offer reliable water resistance. The felt base provides a strong absorbent layer, while the asphalt saturation creates the waterproofing barrier.
- High-Temperature Underlayments: Designed for use in areas with high ambient temperatures or with roofing materials that generate significant heat, these underlayments are formulated to maintain their integrity and performance at elevated temperatures without softening or degrading.
The construction of these underlayments emphasizes ease of installation, durability, and long-term performance. Features such as pre-printed guidelines for overlap and fastening can be incorporated to ensure proper installation and optimal water-shedding capabilities. The specific combination of materials and manufacturing techniques ensures that Owens Corning underlayments meet industry standards for fire resistance and wind uplift, contributing to the overall integrity and safety of the roof system.

Options-Styles
Owens Corning offers a range of underlayment products designed to provide a critical secondary layer of protection beneath your roofing shingles. These underlayments play a vital role in safeguarding your home from water intrusion in the event that shingles are damaged or blown off by wind, as well as providing enhanced protection against ice damming in colder climates. They also create a smooth, clean surface for shingle installation, contributing to a more aesthetically pleasing and longer-lasting roof system.
The style of Owens Corning underlayments generally falls into two primary categories, catering to different performance needs and installation preferences:
- Felt Underlayment: This is a traditional and cost-effective option. It's typically made from asphalt-saturated felt paper, offering reliable water resistance. Felt underlayment is known for its ease of installation and familiarity among roofing professionals.
- Synthetic Underlayment: Representing a more modern and advanced solution, synthetic underlayments are engineered from polymer-based materials. These products are generally lighter, stronger, and more resistant to tearing than felt. They often offer superior water holdout and can provide enhanced UV resistance before shingle installation. Many synthetic options also feature improved slip resistance, aiding in worker safety during installation.
Owens Corning provides specific underlayment products within these styles, each with its own set of features and benefits. While specific product names and detailed technical specifications can vary and are best consulted directly for the most up-to-date information, the general options available typically include:
- Standard Felt Underlayment: Designed for general-purpose use, offering a good balance of protection and value.
- High-Temperature Felt Underlayment: Formulated to withstand the higher temperatures often found under dark-colored shingles, preventing degradation and maintaining its protective properties.
- Synthetic Underlayment Options: These can range from general-purpose synthetic underlayments to specialized products designed for enhanced durability, superior water resistance, and increased tear strength. Some may also offer specific features like enhanced grip surfaces.
When selecting an Owens Corning underlayment, considerations such as local climate, the type of shingles being installed, building codes, and project budget will influence the best choice. Each underlayment is engineered to work seamlessly with Owens Corning roofing systems, contributing to the overall integrity and longevity of your roof.
