What Is Standing Seam Metal Roof

Jun 19, 2023

A standing seam metal roof is a type of roofing system that uses interlocking metal panels to create a watertight seal. The panels are formed into standing seams, which are vertical ridges that run the length of the roof. Standing seam systems may be utilized either on roofs or walls.

Standing seam systems rely on hidden fasteners; whether the panel is attached using clips or fastened directly onto decking material using its vertical leg (fastener flange).

Sizing, Options & More for Standing Seam Panels

Panel Widths

Standing seam metal roof panels offer various profile options and sizes to suit different requirements. Panel widths can be purchased prefabricated or roll formed on-site, depending on performance needs and buyer preferences. While sizes may vary among manufacturers, most standing seam panels range from 12″ to 18″ in width, with 16″ being the most popular choice. It’s important to note that panels found in big box stores may feature wider exposed fastener panels, which can compromise performance. If more comprehensive panels are desired, consulting with the supplier and installer is advisable to ensure engineering validation and suitability.

Seam Heights

The height of the standing seam portion, also known as the “rib height,” is a crucial aspect of panel systems. Standing seam systems typically offer seam widths ranging from one to three inches, with 1 1/2″ and two-inch seams being the most commonly chosen options. Snap-lock systems, often specified in commercial settings, frequently feature 1 3/4-inch seam widths. It’s worth noting that the design and features within the seams have a significant impact on performance, particularly in uplift situations. For example, a 1.5″ Snap-Lock 550 with additional clips and strategic bends in the male leg provides superior uplift performance compared to a similar-looking 1.75″ seam.

Striations, Rib Stiffeners, or Rib Rollers

Striations, or stiffening ribs or rib rollers, are patterns roll formed into metal roofing panels between seams. These features serve various purposes, such as aiding installation, reducing oil canning, or enhancing visual appeal. It is highly recommended to include striations with standing seam panels. Some available options include:

  • Flat: Panels with no indents between seams.
  • Striated: Panels with small indentation lines on the surface, creating a series of marks.
  • Ribbed: Panels with ribbing that defines indentations between seams, adding visual interest and three-dimensional texture.
  • Pencil: Indents for circular panels.
  • V-Ribs: “V”-shaped panel indents.
  • Bead: Longer rectangular panel indents.
  • Clip Relief: Stiffening ribs near seams that create space for clips, allowing for clip relief installation.


Rollformed metal coil panels come in different thicknesses. Standing seam panels typically range from 22 to 26 gauges, with 24-gauge Galvalume® steel being a common choice. Aluminum standing seam panels are available in thicknesses ranging from 0.32mm to 0.040 inches.

Benefits of Standing Seam Metal Roof

Standing seam metal roofing is a popular choice for commercial and residential roofing applications. Here are some of the benefits of standing seam metal roofing:

Fasteners Concealed for Enhanced Protection

One of the standout advantages of standing seam metal roof is its hidden fasteners, providing enhanced protection against UV radiation, moisture intrusion, wind force, and other environmental elements. With no exposed fasteners, the risk of wear or failure due to these factors is significantly reduced. Additionally, the absence of visible fasteners preserves the sleek and clean aesthetic of the roof, which many homeowners prefer. It’s important to note that flashing materials may require rivets or exposed fasteners for functional purposes.

Engineered Solutions Tested to High Standards

Reputable manufacturers subject standing seam metal roof systems to rigorous quality control measures, ensuring they meet high standards. These engineered systems have demonstrated their performance in extreme climates, making them particularly advantageous in hurricane-prone and high-wind zones. With their proven durability and reliability, standing seam roofs offer peace of mind and long-lasting protection.

Thermal Mobility and Expansion

Standing seam metal roofing systems are designed to accommodate thermal movement, minimizing potential issues such as oil canning, fastener withdrawal, and increased noise levels. Standing seam panels do not restrict expansion and contraction by pinning the panels, unlike other roofing options. Including expansion clips or using snap-lock systems allows for optimal thermal movement of each panel, ensuring stability and minimizing the risk of damage.

Longevity & Lifespan

Metal roofing, including standing seam systems, offers exceptional longevity and requires minimal upkeep compared to other roofing materials like shingles or tiles. Using fasteners that do not penetrate the metal surface reduces the need for frequent checks for loose or damaged fasteners. While regular inspections by professional contractors are still recommended, the maintenance requirements for standing seam roofs are generally lower, contributing to their long-term cost-effectiveness.

Warranties for Added Protection

Many manufacturers provide warranties for standing seam systems, offering further protection and peace of mind. Weather-tight warranties ensure that the roof won’t fail, and manufacturers may also provide repair arrangements in case of any issues. It’s important to note that weather-tight warranties are often more commonly available for commercial projects.

Sleek, Consistent & Modern Look

A standing seam metal roof sleek and modern aesthetic has made them increasingly popular in architectural applications. These roofs feature clean lines and can be customized with various colors, including custom hues to complement the structure they adorn perfectly. The modern look of standing seam roofing adds a touch of sophistication to any building.

Architectural Freedom and Design Flexibility

Standing seam metal roof offers architects greater freedom in designing structures with various planes or complex designs. The versatility of standing seam profiles allows for seamless integration into architectural visions, making them a preferred choice for many architects seeking functionality and aesthetic appeal.

Materials with Diverse Attributes

While galvalume and steel are common substrates for standing seam metal roofing, other materials such as aluminum, zinc, and copper can also be viable options. Each material brings unique attributes and characteristics to the roof, providing flexibility and customization options to meet specific project requirements.
