What Is a Standing Seam Metal Roof?
A standing seam metal roof features a flat central section with raised vertical seams along the edges. This roofing system uses a concealed fastener design, meaning fasteners are hidden beneath the panels, protecting them from weather exposure.
Known for its exceptional water-tightness and durability, standing seam metal roofing provides long-lasting performance. However, due to its premium construction and installation process, it is one of the more expensive metal roofing options.
Types of Standing Seam Metal Roofing Panels
Standing seam metal roofing comes in three main types, all featuring a concealed fastener system. This design keeps fasteners hidden, protecting them from the elements and making these panels more weather-resistant and durable compared to exposed fastener options.
- Mechanically Seamed – Panel edges are locked together using a roof seamer, ensuring a tight, secure fit.
- Snap Lock Panels with Concealed Fasteners and Clips – Clips attach to the panel and fasten directly onto the roof deck for easy installation.
- Nail Strip (Nail Flange) Panels – A standing seam panel that eliminates the need for clips, simplifying the installation process.

MS2® Mechanically Seamed
This is the most weather-tight type of standing seam metal roofing, making it an excellent choice for low-slope roofs with a pitch as low as 0.5" to 1":12". Due to its complexity, installation requires professional expertise and is rarely attempted by DIY roofers.
- Mechanically Fastened Seams
- Double Lock Or Single Lock
- 2″ Seam Height
- The Most Expensive Standing Seam

Western Lock® Standing Seam
This standing seam panel offers the best **balance of performance, affordability, and ease of installation**, making it an ideal all-around roofing solution.
- Snap Lock With Concealed Fasteners And Clips
- 1.75″ Seam Height
- Our Most Popular Standing Seam

Western Seam® Nail Strip
Nail strip roofing panels feature a snap lock system that uses screws instead of clips. The male flange includes one-inch slots spaced six inches apart, allowing for direct fastening to the roof deck. While this design makes installation slightly easier and more affordable, it comes at the cost of reduced performance. Without clips, these panels offer less expansion and contraction capability, making them inferior to MS2® or Western Lock® in terms of durability and weather resistance.
- Nail Strip or Nail Flange System
- 1″ or 1.5″ Seam Height
40 year lifespan
The majority of standing seam metal roofing installations use 24-gauge steel, known for its strength and longevity. As a premium roofing system, it is designed to last 40+ years, with all components working together for maximum durability.
Standing seam panels are among the most expensive roofing options and feature the highest-quality paint systems. Using a lighter gauge steel for minor cost savings would compromise performance, making it an impractical choice for a long-term investment.

Standing Seam vs. Corrugated Metal Roofs: Key Differences
The main difference between standing seam and corrugated metal roofing lies in their attachment method:
- Standing Seam Roofing – Uses a concealed fastener system, meaning fasteners are hidden beneath the panels. This design prevents fasteners from penetrating the panel’s surface, enhancing weather resistance, durability, and aesthetics.
- Corrugated Metal Roofing – Features an exposed fastener system, where screws are drilled directly through the panel to secure it to the structure. While more affordable and easier to install, this method increases the risk of leaks and requires more maintenance over time.
Both options provide durability, but standing seam offers a sleeker look and better long-term performance, while corrugated panels are a cost-effective and traditional choice.
