Types of Standing Seam Metal Roofs

Standing seam metal roofs are popular for residential, commercial, and industrial projects. They provide many advantages to owners. With the initial investment, energy savings, a variety of design options, durability, impressive longevity, and more can all be expected.

When deciding which type of standing seam metal roof is right for your home, you must first understand exactly

what these metal roofs are and their advantages and disadvantages.

What are standing seam metal roofs?

A concealed fastener system is common to all standing seam metal roofs. The design has vertical legs and an area between the legs topped with a large, flat metal panel. Since its raised seams allow for protected fasteners, increased durability, and incredible longevity, this is why this roofing type is so popular.

The most common way for standing seam metal roofs to be installed is vertical, from eaves to ridges. As their fasteners are concealed and not visible, standing seam metal roofs have a pleasing visual aspect while providing practical benefits. 

In addition, they require minimal maintenance and are highly reliable. Standing seam metal roofs are attached directly to the decking beneath the versatile legs with a fastener flange or a clip.

Types of Standing Seam Metal Roofs

Standing seam metal roofs have different options, making it difficult to decide which one is best for your home. Although there are countless types, all can be sorted by three factors: the way the panels attach, the shape of the panels, and how they engage with each other.

Attachment Method

The panels attached to the roof constitute this aspect of a standing seam metal roof. Roof decks, rafters, and purlins can all be attached to them. Fastening flanges and clips are the two main methods for attaching standing seam metal roofs.

Fastening Flange

Roof decking is attached directly to this type of attachment method. Fasteners are inserted into slotted flanges, and then a panel snaps onto the slotted flange to cover the screw and the fastening flange.

This type of roof is unsuitable for weather-tightness guarantees or solid roof decks for proper installation. Finally, the slotted flange attachment allows for less contraction and expansion, a characteristic of metal panels, which means that these panels work best for smaller projects.

Clip

Clamped attachment methods attach the roof to the substructure with a heavy steel clip. These clips support male and female legs. An open frame or a solid deck can be covered with clips. These attachment methods also offer the advantage of extending and expanding far more than a fastening flange.

Thus, they are suitable for a wide range of projects. Standing seam metal roofs with clip-attached seams can also offer weather tightness warranties.

Panel Shape

Standing seam metal roof panels come in many different shapes, sizes, and types. They differ in their width and seam height most of all. These seemingly insignificant details can significantly impact your roof's performance.

Snap Lock

Snapped connections fasten male and female legs together with a snap-in-place method. The legs are aligned beside each other during the installation process to make the process easier. The legs are generally pressed together with hands. When the legs engage, the upper panel is pushed into the lower panel. In some cases, a rubber mallet can help snap engagement styles when they are done by hand.
