Supraseal Tape: Elevating Seam Integrity in Single Ply Roofing Systems

by Tom Rowlay

At Supraseal, we understand that the longevity and performance of single-ply roofing systems hinge on the integrity of seams and joints. That’s why we offer Supraseal tape—a top-tier solution designed specifically for sealing seams and penetrations in single-ply roofing applications. In this overview, we’ll explore the unique features and compliance of Supraseal tape with various roofing systems, with a focus on upstand details and corner applications.

What is Supraseal Tape?

Supraseal tape is a high-performance adhesive tape crafted to provide a waterproof seal for single-ply roofing membranes. Made from premium materials, our tape ensures excellent adhesion, flexibility, and resistance to the elements, forming a reliable barrier against water infiltration.

Key Benefits of Supraseal Tape

  1. Exceptional Adhesion: Supraseal tape is designed for optimal bonding with a range of roofing materials, creating a strong and durable seal that can withstand movement and thermal expansion.

  2. Flexibility: Our tape adapts seamlessly to the contours of your roofing surface, making it ideal for irregular shapes and complex details.

  3. Weather Resistance: Built to endure extreme weather conditions, including UV exposure and temperature fluctuations, Supraseal tape maintains the integrity of your roofing system over time.

  4. Easy Installation: With a user-friendly design, Supraseal tape can be applied quickly and efficiently, helping to reduce labor costs and installation time.

Compatibility with Single Ply Roofing Systems

Supraseal tape is fully compliant with a variety of single-ply roofing systems, including:

  • EPDM (Ethylene Propylene Diene Monomer): Our tape adheres strongly to EPDM membranes, providing reliable sealing for seams and penetrations.

  • TPO (Thermoplastic Polyolefin): Supraseal tape’s unique composition ensures effective bonding with TPO roofing systems, delivering a leak-proof installation.

  • PVC (Polyvinyl Chloride): Designed to work seamlessly with PVC membranes, Supraseal tape meets the rigorous performance requirements necessary for lasting seals.

Specialized Applications: Upstands and Corners

Upstand Details

Upstands, or vertical projections on the roof, often require meticulous sealing to prevent water ingress. Supraseal tape excels in these applications by providing a robust, waterproof seal at the junction between the upstand and the roofing membrane. Key considerations for installing Supraseal tape on upstands include:

  • Surface Preparation: Ensure the vertical surface is clean and dry before application. This enhances adhesion and ensures a proper seal.

  • Full Coverage: Apply the tape to fully cover the junction where the upstand meets the membrane, overlapping the tape sufficiently to create a continuous barrier.

  • Sealing: Press down firmly on the tape, particularly at the edges, to ensure that there are no gaps where water could potentially enter.

Internal and External Corners

Corners are critical areas that require special attention during installation. Supraseal tape is designed to handle both internal and external corners effectively.

Internal Corners

  • Application: When sealing internal corners, cut the tape to the appropriate length to fit snugly into the corner. This minimises stress on the tape and enhances waterproofing.

  • Sealing Technique: After applying the tape, ensure that it adheres well to both surfaces of the corner. Use a roller or your hand to press it firmly into place.

External Corners

  • Angle Adjustment: For external corners, cut the tape to accommodate the angle of the corner. It’s essential to ensure that the tape overlaps onto the roofing membrane for maximum protection.

  • Double Layering: In high-stress areas like external corners, consider applying a second layer of tape for additional security against potential leaks.

Installation Guidelines

For optimal results when using Supraseal tape with single-ply roofing systems, we recommend the following installation practices:

  1. Surface Preparation: Ensure surfaces are clean and free from debris, dust, or contaminants that could hinder adhesion.

  2. Temperature Considerations: Apply Supraseal tape within the recommended temperature range to achieve the best bond.

  3. Overlap and Coverage: Ensure adequate overlap at seams to create a continuous waterproof barrier.

  4. Pressing and Sealing: Firmly press down on the tape to ensure complete contact with the roofing material. Using a roller can help eliminate air bubbles.

Conclusion

Supraseal tape is a trusted solution for enhancing the durability and performance of single-ply roofing systems. With its exceptional adhesion, flexibility, and weather resistance, our tape is the ideal choice for sealing seams, upstands, and corners. By following our installation guidelines, roofing professionals can ensure compliance and achieve long-lasting results. Whether working with EPDM, TPO, or PVC, integrating Supraseal tape into your roofing project helps safeguard against leaks and extend the life of your roofing system.
