These systems require less labor and are generally cheaper to install because no mechanical seaming is required.Snap-lock panels can be used in any environment as long as they’re installed correctly.Snap-lock systems should only be installed on roof pitches (slope) of 3/12 and above unless otherwise approved by the manufacturer.Fastener flange panels use a similar locking mechanism however, we do not consider fastener flange a snap-lock because true snap-locks allow the system to float freely with its clip system. Snap-lock profiles are attached to the roof deck using a clip that attaches to the seam and fastens underneath the panel. Snap-lock profiles consist of panels that have been carefully rollformed with specifically shaped edges, a male and female leg, that snap together and do not require hand or mechanical seaming during installation. Many panel profiles comprise the standing seam category, including snap-lock, mechanical seam, batten panel, and nail/fastener flange. Depending on what type of roof you have, how steep it is, what environment your property is in, and various other factors, it will dictate what profile you should pick with the help of a contractor or architect. One of these choices is the panel profile type.Ī panel profile refers to the shape and way two or more panels are seamed together. These choices stretch far beyond just the panel’s color to include the length, width, profile, shape, thickness, etc. One of the most significant selling points of standing seam metal roofing is the variety of choices and options for customers. The main idea for standing seam systems is that the fastener is hidden, whether the panel is attached to the roof deck using a clip or is directly fastened to the decking material under the vertical leg (fastener flange). Standing seam systems can be used for either metal roofing or metal walls. It’s also described as having raised seams, or vertical legs, that rise above the panel’s flat area. Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad, flat area between the two legs.
