Standing Seam Metal Roofing Panels
Durable, High-Performance Systems
Standing seam metal roofing panels are the benchmark for performance, aesthetics, and long-term protection in today’s roofing systems. Designed with concealed fasteners and raised interlocking seams, they deliver superior weather resistance, durability, and a sleek, modern look that complements both residential and commercial architecture.
Types of Standing Seam Metal Roofing Panels
The two primary types of standing seam roofing panels are: mechanical seam panels and snap-lock panels. Mechanical seam systems are crimped together on-site, creating a continuous, watertight seal that performs exceptionally well for low-slope roofs and demanding environments. By contrast, Snap-lock panels feature a precision-forms locking mechanism that “snaps” into place without seaming tools, making them faster and easier to install while still maintaining excellent performance. Depending on your project requirements, snap-lock options include clip-fastened systems for enhanced thermal movement, and nail strip systems for straightforward installation for smaller spans and residential applications.
