Types Of Standing Seam Metal Roofs

Types of Standing Seam Metal Roofs

The product selection from types of standing seam metal roofs can seem daunting with so many panel variations. Standing seam panel types are distinguished by how they are engaged with each other and how they are laid on the roofing surface. The mechanism of attachment, engagement, designs and styles affect the initial cost and maintenance cost. With an appropriate choice of roof, you can save time, effort, and money for yourself.

Different types of standing seam metal roofs comprise metal panels and metal sheets that have been prefabricated or formed on site. Steel and Stud offer standing seam panels in different colors, gauges, and heights in your area.

Standing Seam Roofs

Standing seam metal roofing has vertical legs or elevated seams that protrude above the panel’s smooth and flat surface. Choose standing seam metal roofs over corrugated metal panels if the weather condition is severe in your region or you have a low slope roof. The standing seam gives a smooth seamless look to your roofing system with no barriers to block rainwater, snow, and debris and accumulate there.

There are several ways to attach a standing seam metal roof, but the two most popular types are clipped and fastening flange. Purlins also help in strengthening your metal roof.

Nail Fastening Flange

nail strip panels
Nail Fastening Flange

Also referred as nail strip panels, these panels are directly fastened to the roof deck with a fastener through a slotted flange. As metal roofs become hotter, the slotted flange limits the panels’ ability to expand and contract to around 45′. The most significant places for installing these exposed fastener systems are residences and other small, light commercial structures.

  • Cheapest standing seam with exposed fastener panels
  • Professional installers must fasten the screws properly to avoid any restriction movement.
  • The metal close to the fastener head could rend due to ongoing expansion and contraction.

Clipped Snap lock

Clipped systems latch to the substructure using a heavy gauge steel clip incorporated with the male and female leg on the panel instead of nail-type panels that use flanges. In snap lock panels, the vertical legs are fitted over one another during installation, and the upper part is pushed down into the lower part until the legs correctly join.

Snap lock and Mechanical Lock
  • No extra tools are required during installation.
  • The installation process is precise and more affordable.
  • Concealed fasteners save the cost of rubber sealing washers, which often need to be replaced due to ongoing expansion and contraction.

Mechanically Seamed

Standing Seam Metal Roof Types

In contrast to snapped panels, mechanically seamed panels require using motorized seaming equipment for installation and engagement. The mechanical seam profile comprises panels with roll-formed edges that align with one another. The clip is attached to the male leg using the same screws used in the snap-lock profile. The edges can be bent manually or mechanically once the panels are connected.

There are two types of mechanical seams:

  • Single lock
  • Double lock

The panel seams are folded twice, once in a single lock and twice in a double lock.

  • Most expensive standing seam metal roofs
  • Require expertise, professional help, and tools.
  • Most weather-tight.

Standing seam metal roof advantages and disadvantages

The main benefit of employing a standing Seam roof is its endurance, which outweighs its aesthetics and the potential cooling effect it may have on your property. These roofs are made to last; therefore, neither do they rust nor do most of them fade in the sun. The installation is this type of roof’s major drawback. Fewer roofers understand metal roof installation and metal roof materials, while the majority of roofers work with asphalt roofs. This indicates that it can be more challenging to locate someone informed about the type of roof.
