Depending on the type of roof you have on your home, how steep it is, the environment your property is in, and a variety of other factors will dictate what standing seam type you should pick – along with the help of a contractor or architect. There are different panel profiles that make up the standing seam category, including:

Nail Flange/Fastener Flange

Nail flange (also referred as a fastener flange) is similar to a snap-lock panel system, but instead of using a clip to attach the panel to the roof deck, it is directly fastened down to the deck through the male leg of the metal panel. Once the fasteners are in place, the female leg of the panel snaps over the entirety of the male leg, which hides the fastener head.

Snap-Lock

Snap-lock profiles are panels that have been carefully roll-formed with specifically shaped edges, a male and female leg, that snap together and don’t require hand or mechanical seaming during installation.

Snap-lock Quick Facts

• Snap-lock systems should only be installed on roof pitches (slope) of 3/12 and above, unless otherwise approved.
• Snap-lock panels can be used in any environment as long as it’s installed correctly.
• These systems require less labor and are generally cheaper to install because no mechanical seaming is required.
• Engineered snap-lock panel systems­ deliver known performance, unlike non-engine­ered versions.

Mechanical Lock

Mechanically seamed panels are also roll-formed with specific edges that line up with each other. Once the two panels are engaged, a hand or mechanical seamer is used to bend the edges and lock the panels together. There are two different versions of mechanical seams: Single lock 90-degree seams and double lock 180-degree seams.
