Standing Seam FAQ
Expert answers to frequently asked questions about Standing Seam metal roofing systems, installation, and performance.
🏗️System Overview
What is Standing Seam metal roofing?
Standing Seam is a premium metal roofing system where panels are connected with raised seams that run vertically up the roof slope. The panels are secured with a concealed clip system, meaning no fasteners penetrate the panel surface, creating a completely weather-tight system.
How does Standing Seam differ from Snaplock?
Standing Seam uses a concealed clip system with mechanical seaming, while Snaplock has an integrated nail strip. Standing Seam provides superior weather resistance and accommodates thermal movement better, making it ideal for commercial and high-end residential applications.
What panel widths are available?
Standing Seam panels are available in widths from 12" to 24". Narrower widths (12"-16") create more seam lines for a traditional appearance, while wider panels (18"-24") provide faster installation and modern aesthetics.
What is the minimum roof pitch for Standing Seam?
Standing Seam requires a minimum pitch of 1:12 (8.33%) or approximately 5 degrees. This low slope capability makes it suitable for commercial applications and modern architectural designs with shallow roof pitches.
⚙️Installation & Performance
Does Standing Seam require special installation tools?
Yes, Standing Seam installation requires a portable seaming machine to mechanically join the panel seams. The clip system also requires specific tools and training. Professional installation by certified contractors is strongly recommended.
How does the clip system work?
The clip system secures panels to the roof structure while allowing thermal movement. Fixed clips are used at panel centers, while sliding clips accommodate expansion/contraction. This system prevents panel buckling and ensures longevity.
What wind speeds can Standing Seam withstand?
Properly installed Standing Seam systems are rated for winds up to 150 mph (241 km/h) when tested to ASTM E1592 standards. The concealed fastening system provides superior uplift resistance compared to exposed fastener systems.
How does Standing Seam perform in snow loads?
Standing Seam systems excel in high snow load conditions. The structural integrity of the seamed joints and clip system distribute loads effectively. The smooth surface also promotes snow shedding, reducing sustained loads on the structure.
🛡️Materials & Durability
What materials are Standing Seam panels made from?
Standing Seam panels are typically made from Galvalume (aluminum-zinc coated steel) or aluminum. Galvalume provides excellent corrosion resistance, while aluminum offers superior longevity in marine or industrial environments.
What paint systems are available?
Standing Seam panels are available with Kynar 500® PVDF or SMP polyester paint systems. PVDF offers superior fade resistance and longevity, while SMP provides excellent performance at a lower cost point.
How long do Standing Seam roofs last?
Standing Seam roofs typically last 50+ years with proper installation and minimal maintenance. The concealed fastening system eliminates fastener degradation, which is a common failure point in other metal roofing systems.
Are Standing Seam panels recyclable?
Yes, Standing Seam panels are 100% recyclable at the end of their service life. Metal roofing is one of the most sustainable roofing options available, often containing significant recycled content in manufacturing.
💰Cost & Applications
Is Standing Seam more expensive than other metal roofing?
Standing Seam has a higher initial cost than exposed fastener systems due to the specialized installation requirements and concealed clip system. However, the longevity and minimal maintenance requirements provide excellent long-term value.
What types of buildings are best suited for Standing Seam?
Standing Seam is ideal for commercial buildings, high-end residential homes, and any application requiring superior weather resistance. It's particularly well-suited for low-slope roofs and buildings with large roof areas.
Can Standing Seam be used on curved roofs?
Yes, Standing Seam panels can accommodate gentle curves when properly designed. The clip system allows for some flexibility, though significant curves may require special engineering and fabrication techniques.
What maintenance is required?
Standing Seam roofs require minimal maintenance. Annual inspections should verify that clips remain secure and drainage systems are clear. The absence of exposed fasteners eliminates the need for regular fastener maintenance.
