What Is A Standing-Seam Metal Roof?

Lately, a number of people have been requesting estimates for standing seam metal roofs. This type of residential roofing system is becoming increasingly popular because of its unique look and many benefits. Just a few years ago, metal roofs were seen mainly on commercial buildings. Today, standing seam metal roofing systems are a common choice among homeowners because the initial higher cost of metal roofing will likely pay off over time. Not to mention, standing seam metal panels can also increase the curb appeal of your home!


What Is A Standing-Seam Metal Roof?


Standing-seam metal roofing is installed by running continuous metal panel systems down the length of the roof. These standing seam panels are usually made of Galvalume-coated steel but can also be made of aluminum, copper, and various other metals.

Each 12 to 19-inch wide panel overlaps the other, concealing the seam fasteners with a “standing seam” running continuously from the top of the roof to the edge. This seam can vary in height but is typically 1 inch to 2-1/2 inches.

The panels are held in place with clips that are concealed under the panel, thus allowing the panel to float or move back and forth. Standing seam metal roof panels can either be formed on-site by taking a roll of metal and running it through a mobile panel machine to form specific length panels or can be pre-formed in factories.

Advantages of Standing Seam Metal Roofing Systems


Standing seam systems are very durable and much more impact-resistant than other roofing materials such as asphalt roof shingles as long as you have an appropriate gauge of steel. Be aware of some companies suggesting a type of standing seam metal roofing system with a thinner gauge of steel. It’s much more flimsy, less durable, and creates more oil canning in the snap lock panels. A metal roof installed correctly will often last for more than 50 years.

FIRE RETARDANT & Low Maintenance

On top of this, metal roofs are fire retardant, recyclable, and require very little maintenance. The money will also be saved on your energy bills because metal panels painted with lighter colors reflect much more heat than asphalt shingles. These roofs also add a bright, impressive look and increase the value of your home.

Because the installation process and materials are often two to three times higher than typical asphalt shingles, it is important to calculate whether the higher initial cost will be a better investment for you over time as opposed to other types of roofing.

No Exposed Fasteners

Concealed fasteners – Standing seam systems have mechanically locking 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.

Hidden fastener systems mean they aren’t exposed to UV, moisture, wind, and other elements that can cause a fastener to wear or fail over time. The best roofing companies know this is a major plus, as holes in the panels can cause water leaks as well as hot and cold air leaks and impact your home’s energy efficiency.

Plus, some people see fastener heads as unsightly, which is why using a standing seam system to hide them is common.

Thermal Movement

Restricting the expansion and contraction needed for proper thermal movement of a metal panel can cause problems, such as oil canning, fastener withdrawal, increased noise, and more. Standing seam roofing system panels generally aren’t double-pinned. Therefore, 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.


Engineered standing seam metal roofing systems typically adhere to testing standards for wind uplift, air leakage, water penetration, fire/combustion resistance, and impact resistance in commercial and residential applications.
