Roofing Tips


Standing seam metal roofing is quickly becoming one of the most popular roofing options for property owners in South Florida. Available in a variety of colors, styles, and application methods, there are a number of advantages to investing in this metal roofing option. Installed by a professional like Aabco Roofing, this metal roofing option is both durable and cost-effective.

What Is Standing Seam Metal Roofing?

Standing seam metal roofing is a fastener roofing system. This system is concealed, and features vertical legs with flat space in between.

The standing seam metal roofing panels are attached to the deck with clamps. The presence of clamps allows for a hole-free roofing system, reducing the risk of leaks. Its concealed design ensures that the fasteners, the component most likely to fail, are protected against the elements.

Growing in popularity, this metal roofing system is known as one of the most durable and weather-tight roofing options available to property owners. The most significant selling point is the variety of choices and options available, with the most popular being:


Snap-lock profiles have roll-formed panels with specifically-shaped edges. A female and male leg snap together, eliminating the need for mechanical seaming during installation. A clip is attached to the seam and fastens under the panel, securing the roofing system to the deck. Snap-lock profiles require less labor and are generally the cheaper option.

Mechanical Seam

Similar to snap-lock profiles, mechanically seamed profiles have roll-formed panels with edges that line up. When in place, a mechanical seamer is used to bend the edges, locking them into place. Choosing this profile means that you can have your panels single or double locked.

Single locked panels (90-degree seam) means that there is only one-fold on the seam. Although this version performs better in milder environments, it is easier to replace damaged panels should the time come.

Double locked panels, as I’m sure you’ve guessed by now, means that there are two-fold In the seam. An extra fold reduces the chance of the panels coming loose, improving its performance.

Batten Panel

The batten panel profiles have two legs that are roll-formed and butted up next to each other. A metal cap is then placed over the legs, creating a seam. Two types of caps are available, namely tee seams and snap caps.

Tee seams require a mechanical application, meaning that they perform well in harsh environments. The caps are fitted with a pre-installed sealant and are easy to replace.

While the snap cap doesn’t require mechanical applications, its performance is dependent on correct installation.

Nail Flange

A nail flange system is also commonly known as a fastener flange system. It is directly fastened to the roofing deck through the male leg of the panel. The female leg snaps over the male leg once the fasteners are in place. While this is not the highest performing option, it is one of the most popular choices for residential applications because of its low price.

Advantages Of Standing Seam Metal Roofing

There are a number of reasons that standing seam metal roofing is growing in popularity, some of which are:

Hidden Fasteners

Arguably the most significant benefit of this metal roofing system is the lack of visible fasteners on the surface of the roof. Not only is it more aesthetically pleasing, but the fasteners’ lifespan is extended.

Additionally, standing seam systems do not put holes in the panels. This lowers the risk of a leak or the development of a weak spot on your roofing system.

Thermal Movement

Generally, these systems are not double pinned. This allows room for the natural expansion and contraction of the roofing system. Restriction of these movements could cause issues with your metal roof.

Life Span

Metal roofing lasts longer and requires less maintenance. It is also typically offered with a coat of PVDF paint, a resin-based coating system that improves its lifespan.


Standing seam metal roofing systems have been tested against the highest standards set by the industry leaders. Engineered standing seam metal roofing systems typically follow testing standards for wind uplift, air, and water leakage, as well as fire and impact resistance.
