Standing Seam Panels – Strength, Longevity, and Style for Every Project
High-performance standing seam roof systems delivering structural strength, architectural appeal, and decades of proven reliability.
Standing seam metal roofing systems deliver premium performance through concealed-fastener design, raised interlocking seams, and engineered clip systems that allow for thermal movement. McElroy Metal's standing seam portfolio includes architectural, structural, snap-together, and mechanically seamed profiles suited for residential, commercial, and high-wind applications.

138T and 238T systems are classified as symmetrical standing seam systems and offer many advantages over traditional standing seam panels. Due to the symmetrical standing seams, individual panels can be removed and replaced in the event of damage. McElroy Metal's Shingle Recover System features the 138T panel and is an economical and energy efficient method to recover an existing shingle roof.
The symmetrical trapezoidal profile delivers superior wind uplift performance and on-site forming lengths up to 250' eliminate end-lap vulnerability common in traditional trapezoidal panels. Mechanical seaming provides exceptional weather resistance, while the symmetrical design allows individual panel replacement for easier long-term maintenance.

Green Span Profiles, a McElroy Metal joint venture, manufactures RidgeLine IMP roof panels featuring a 238T symmetrical standing seam and thicknesses from 2½" to 5". These Insulated Metal Panels (IMPs) combine structural strength, insulation, and finish into a single, energy-efficient component.
Our Ridgeline's slide-in joint lets crews position panels without heavy rolling, reducing coordination and lift strain. Meanwhile, the symmetrical design allows installers to start anywhere on the roof and replace individual panels without disturbing adjacent ones.
