During installation, the vertical legs are positioned over each other, and then pressure is applied to push the upper panel down onto the lower panel until the legs properly engage. Snapped: As you might expect, the male/female legs on snapped panel systems simply snap in place due to their design. There are also two primary methods of panel engagement: snapped and mechanically seamed. Based on the panel design and installation requirements, weather tightness warranties are common with clipped panel systems. As a result, they are much better suited for the long panel runs commonly found in educational, commercial, and industrial applications. These clipped systems tend to offer more significant expansion and contraction features than fastening flange style panels.

While fastening flange systems require a solid deck, clipped systems typically install over either solid deck or open framing like that commonly found in pre-engineered metal buildings. Consequently, these panels are best suited for residential applications and smaller light commercial structures.Ĭlipped: Unlike fastening flange style panels, clipped systems attach to the substructure with a heavy gauge steel clip specifically designed to integrate with the male/female legs on the panel. Additionally, the slotted flange limits the expansion and contraction ability of the panels to around 45’. These types of panels are typically not suitable for projects requiring a weathertightness warranty, and they require a solid roof deck for attachment. While this attachment style is the most economical standing seam panel to purchase and install, there are limitations. The next panel then snaps on top and covers both the fastening flange and the screw. There are two main styles of attachment: fastening flange and clipped.įastening Flange: As the name implies, this family of panels is attached directly into the roof deck by inserting a fastener through a slotted flange. The attachment method for standing seam panels refers to how the panels are physically attached to the roofing deck, rafters, or purlins. With a better understanding of these criteria, product selection becomes much more manageable. How they attach, how they engage with each other, and the panel shape. However, there are three defining factors with standing seam panels. With so many panel options, product selection can feel a bit overwhelming. Consequently, building owners have unparalleled options to find the best product for their particular needs. There are many different types of standing seam metal roof systems. You can read more about the differences between the panel types by clicking here. Beyond the improved appearance, standing seam panels also offer less maintenance and a longer life expectancy since exposed fastener panels can allow water to penetrate the building over time. Since the fasteners aren’t visible, most people prefer the visual look of standing seam panels over their exposed fastened counterparts. This family of panels installs with concealed (or hidden) fasteners. Standing seam systems also feature a raised interlocking seam that connects adjoining panels.
Typically, they are installed vertically and run from eave to ridge. Standing seam metal roofing systems are one of the many roofing options available. Used for commercial, residential, and industrial applications, standing seam metal roofs (also commonly referred to as concealed fastener roof panels) are a versatile roofing option that offers building and homeowners many advantages like cost savings, durability, and a wide variety of design options.
