      Trap-Tee Metal-Over-Metal Recover Ideal Applications

      • Metal-over-metal recover projects where existing roof removal is not desirable.

      • Remove-and-replace retrofits requiring minimal downtime and improved performance.

      • New construction projects demanding superior uplift capacity and panel longevity.

      • Industrial and commercial buildings needing large coverage with minimal maintenance.

      Trap-Tee Metal-Over-Metal Recover Top 3 Benefits

      1. No Tear-Off Required: Installs directly over existing metal roofs—saving time, labor, and disposal costs.

      2. Symmetrical Panel Design: Allows individual panel replacement anywhere on the roof and enables repairs or future modifications without disturbing adjacent panels.

      3. Long-Length Panels and Onsite Rollforming: Single-piece panels up to 250 feet long eliminate lap joints; onsite rollforming reduces damage risk, shipping limits, and storage needs.

      Frequently Asked Questions

      The questions below address common considerations and help guide product selection for your project.

      What makes Trap-Tee different from traditional trapezoidal panels?
      Trap-Tee features a symmetrical rib design that allows for individual panel replacement, eliminating one of the biggest service challenges of older trapezoidal systems.
      Can Trap-Tee be used for both new and recover applications?
      Yes. Trap-Tee is equally well-suited for metal-over-metal recover, remove-and-replace retrofits, and new construction.
      How long are Trap-Tee panels available?
      Panels can be rollformed onsite up to 250 feet long, eliminating leak-prone end laps.
      What slope is required?
      Trap-Tee can be installed on slopes as low as ¼:12, making it ideal for low-slope metal roof conversions.
      What paint systems are available?
      The standard finish is Kynar 500® (PVDF) for maximum color stability and durability; acrylic-coated Galvalume® is available for budget-conscious applications.
