What is a Standing Seam Metal Roof?


Metal roofing is a generic term that relates to a variety of roofing choices and products. When the word metal roofing is used, it could be an exposed fastener roofing system, tiles constructed from metal, or a standing seam metal roof system.

Of all the metal roofing options, a standing seam system is increasing popularity because property owners are looking for long-lasting and modern-looking products that will also provide protection. However, do you know what a standing seam metal roof is?

Standing Seam Metal Roof

roofing company would define a standing seam metal roof as a concealed fastener metal panel system with vertical support legs and a flat section between those two legs. Additional descriptions include a roof with vertical legs that rise above the panel’s flat area. This type of system can be used for metal walls or metal roofing, which is the most common usage.

Types of Standing Seam Metal Roofs

One of the best advantages of this type of system is the number of options for customers that exceed dimensional changes, colors, thickness, and shape. Almost every roofing company offers the following panel profiles:

Batten Panel

The batten panel is constructed with two legs of the panels that are roll-formed and then place next to each other. A metal cap goes over the legs, thus creating a seam and snaps into place.

Mechanical Lock

Mechanically seamed panels are roll-formed with edges that align and, once engaged, a mechanical seamer bends the edges to lock both panels together.

Nail Flange

A nailing flange directly fastens down to the deck using the male leg of the panel. Once the fastener is secured, the female leg then snaps over the male leg thus hiding the fastener.


A snap-lock system consists of panels that are roll-formed with custom edges and male and female vertical supports that snap together without requiring mechanical seaming.
