Roofing Tips


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

What Is Standing Seam Metal Roofing?

Standing seam metal roofing is a fastener roofing system. It’s a concealed system that features vertical legs with flat space in between.

Standing seam metal roofing panels attach using clamps. The clamps allow for a hole-free roofing system. This reduces the risk of leaks. Moreover, the concealed design ensures that the fasteners are protected against the elements.

This metal roofing system is popular. Undoubtedly, it’s 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.

The most most popular choices for standing seam metal roofing are:


Snap-lock profiles have roll-formed panels with specifically-shaped edges. A female and male leg snap together. This eliminates the need for mechanical seaming during installation. A clip is attached to the seam which is then fastened underneath. This secures 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. A mechanical seamer is used to bend the edges and lock 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. This version performs better in milder environments. However, it’s 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. This improves the metal roofing’s 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. This means that they perform well in harsh environments. The caps are fitted with a pre-installed sealant. Even better? They’re 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 commonly known as a fastener flange system. Through the male leg of the panel, it’s directly fastened to the roofing deck. 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 advantages to this type of metal roofing 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

These roofing 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’s also typically offered with a coat of PVDF paint. This is a resin-based coating system that improves a roof’s 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. Additionally, they are tested for fire and impact resistance.
