Standing Seam Metal Roofing Pros & Cons

July 31, 2020
Standing Seam Metal Roofing

Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad, flat area between the two legs. It’s also described as having raised seams, or vertical legs, that rise above the level of the panel’s flat area. Standing seam systems have fasteners that are hidden, whether the panel is attached to the roof deck using a clip or is directly fastened to the deck under the vertical leg utilizing a fastener flange. Standing seam roofing is considered a higher quality system that is commonly used on architectural and commercial buildings.

Advantages of Standing Seam Metal Roofing


Easily one of the most significant benefits of standing seam metal roofing is that no fasteners are visible on the surface, which means they aren’t exposed to UV, moisture, wind, and other elements that can cause a fastener to wear or fail over time. Also, standing seam systems don’t put holes in the panels that are protecting your structure. Plus, some people see fastener heads as unsightly, which is why using a standing seam system to hide them is common.



When you restrict the expansion and contraction needed for proper thermal movement of a metal panel, you can run into problems, such as oil canning, fastener withdrawal, increased noise, and more. In standing seam roofing systems, the panels generally aren’t double pinned, meaning they can expand and contract better. This is especially true if slider/expansion clips are installed or if it’s a snap-lock system where the metal can move freely with a clip.




Metal roofing lasts significantly longer and requires less maintenance, especially when compared to other roofing types, such as asphalt shingles or concrete tiles. Since fasteners don’t penetrate the surface of the metal on a standing seam system, regular maintenance to check for withdrawing, loose, or damaged fasteners is even less frequent. Standing seam metal roof systems typically offer a PVDF paint system, which will increase the lifespan of the appearance of your roof.


College - Standing Seam Metal Roofing


Engineered standing seam metal roof systems are tested to the high standards set forth by industry leaders, including ASTM, UL, and FM Approvals. Requests for engineered construction materials are becoming more and more popular, especially with commercial structures in a hurricane and high-wind zones. Engineered standing seam metal roofing systems typically adhere to testing standards for wind uplift, air leakage, water penetration, fire/combustion resistance, and impact resistance.

Disadvantages of Standing Seam Metal Roofing


One of the most significant drawbacks to standing seam metal roofing is the fact that it can be more expensive when compared to other metal roofing types, especially exposed fastener systems. However, it’s not always the highest price, as metal shingles and other stamped metal materials tend to come in at a higher price, even though stamped materials are often made from 26 gauge or thinner substrates.


For exposed fastener systems, it’s a relatively simple process of putting the material on the roof deck and nailing/screwing it down. We are more than happy to offer this option, however it comes down to what the client is looking for aesthetically and what best fits their budget. However, for standing seam, it’s much more complex and labor-intensive, and may include:

  • Forming the metal panels using portable (on-site) roll forming machine or buying from regional manufacturers
  • Correctly spacing the clips on the panel legs and fastening each one down
  • For snap-lock systems: Aligning the panels and snapping the legs together
  • For mechanically seamed systems: Aligning the panels and hand-seaming or mechanically seaming the panel legs together
  • Making any necessary slits in the metal to account for roof plans, geometry, and flashing areas
