Last Updated on: 13th June 2023, 10:48 am

Ladies and gentlemen, when it comes to metal roofing, one of the most trendy options is standing seam. Within the standing seam family, there are several various profiles to choose from, including snap lock, mechanical lock, nail strip, fastener flange. And, so on. Why so many, you might wonder ? Well, because no two roofs are exactly the same! Each system has its unique quirks, pros, cons, and ideal applications. And today, dears, we’re going to zero in on one particular system that’s been making some noise in the industry: snap lock metal roofing.

What’s Snap Lock Metal Roofing?

Snap lock is a type of metal roof panel that has female and male parts that fit together like puzzle pieces. It uses hidden clips to attach the panel to the roof, keeping it smooth and without visible fasteners. This design allows for the expansion and contraction of the metal due to temperature changes.

Quite ingenious, don’t you think ? Now , the main selling point of the snap lock system is its simplicity and speed of installation. Thanks to the clip system, there’s no need for seaming tools or additional lock saeming during installation. This, in turn, reduces labor costs, which I’m sure you’ll agree, is always welcome advantage!

Why is it Called Snap Lock ?

Have you ever heard snap lock panel click into place? It’s satisfying , plus its gives the system its name. These seam panels lietrally snap together, locking into place and creating a secure, weather-resistant seal. There’s an efficiency to this design that makes it an excellent choice for many metal roofing projects.

But keep in mind, folks, that th esnap lock system is not the be-all and end-all . It works best on roofs with steeepr pitch. For lower sloped roofs, a different type of seam metal roof panel may be more suitable. We’ll dig more into this later.

How Does Snap Lock Compare to Mechanical Lock ?

Oh, the age-old question! Snap lock versus mechanical lock . Both systems are part of the standing seam family. But there are a few crucial differences. The most notable difference? Installation. Snap lock panels simply snap together, while mechanical lock panels require a mechanical seaming tool to join the panels together. This extra step can increaes installation costs for mechanical lock systems.

But it’s not all sunshine and roses for snap lock . The mechanical lock system frequently performs better in extrmee weather conditions, making it a common type for commercial buildings and high-wind areas. As always, there are pros and cons to each system. 

How Does Snap Lock Perform in Residential and Commercial Applications?

Snap lock is often favored in residential applications . Why’s that, Viliam, you ask? Simple. It’s easy to install, making i t a popular choice for residentail buildings with steep sloped roofs. Plus, its exceptional performance and effective weather resistance add to its appeal for homeowners.

On th ecommercial side, snap lock can also be a worthy contender . It’s used in commercial biuldings too, but not as much as its cousin, the mechanical lock. That’s mainly because commercial roofs tend to have lower slopes where the mechanical lock, with its double lock seam, shines.

Nail Strip Or Fastener Flange Systems

Alright , let’s switch gears bit and talk about nail strip systems. Nail strip, or nail flange, is another type of standing seam system. The panels in this system come with pre-formed flange that features a soltted hole for fasteners. It’s called a nail strip because, you guessed it, nails are used to secure the panels to roof deck.

While this system is also easy to install, it’s more susceptible to issues from thermal movement compared to the snap lock and mechanical lock systems. Hence, nail strip systems are best suited for smaller roofs with less complex geometries. Fastener flange is like cousin to nail strip. But with concealed screwss, resluting in a clean, smooth look.

Like snap lock, fastener flange also provides quick installation. But it doesn’t allow for thermal movement. This means that it’s best suited for smaller roof areas or for use in cold weather climates where thermal movmeent is less of a concern.

Sizes, Finishes, And Warranties of Snap Lock Roofing

Snap lock panels come in various sizes and finishes, giving you options to choose from depending on your design preferences and specific requirements of your dear project . Common sizes range from 12 to 20 inches broad and th panels are typically made from coils of sheet metal that are cut to size.

In terms of finishes, snap lock panels are available in a variety of colors and coatings to match any architectural style. And when it comes to warranties, most manufacturers offer some form of limitde warranty, but it’s always important to check the specifics with the manufacturer.

Understanding the Role of Weather Resistance

Let’s talk weather resistance. You see, snap lock panels, with their interlocking design, offer superior weather resistance. They create a continuous, uninterrupted surfcae that effectively sheds water, making them great for areas with heavy rainfalls. Also, the concealed fasteners in snap lock systems reduce th potential for leaks.

Of course, this isn’t to say that snap lock is completely invulnerable . No system is. But with proper installation and regular maintenance, you can significantly enhance weatehr resistance of your snap lock metal roof.

The Importance of Roof Pitch

Now, let’s return to that roof pitch thing. The pitch of your dear roof plays enormous role in determining th ebest type of standing seam system. For instance, snap lock is best for stepeer slopes, while the mechanical lock is go-to for lower slopes.

The reason? Well , water drainage. The steeper roof, the faster the water can run off. And snap lock, with its single lock seam, handlse this beautifully. On the other hand, on lower slopes, water drains more slowly, so double lock seam, like what mechanical lock system offers, is more desirable. 

Your Metal Roofing Project: What To Consider?

Before deciding on metal roofing system, there are a few key things to consider . First off, consider your roof’s slope and waether conditions it will need to withstand. Your choice of standing seam system will largely depend on these two factors.

Then , think about the aesthetic you want to achieve. With variety of panel profiles, sizes, and finisehs available, the world is your beloved oyster!

Why are Installation Costs and Labor Significant?

Installation costs and labor are significant factors when deciding on standing seam system. Snap lock , for instance, is less labor-intensive, thus reducnig installation time and costs. But keep in mind, each system requires specific tools and expertise for proper installation. It might save you some bucks in short term, but getting its installed by professionals ensures your roof is properly set up for the long haul.

Is Snap Lock an Excellent Choice for Metal Roofing?

You bet it is! Snap lock systems offer blend of easy installation, robust weather resistance, and an attractive appearance. It’s no wonder they’re an great choice for many residential and commercial applications. But of course, it’s not a one-size-fits-all situation. Depending on your specific needs and circumstances, other standing seam systesm may be more appropriate.

In a way , yes. The choice between snap lock and other standing seam systems regularly boils down to preference – both in terms of aesthetics and functionality. But it’s also essential to consider the technical aspects, like th slope of your roof, the expceted weather conditions, plus the desired longevity of the roof.

So , What’s the Bottom Line on Snap Lock and Other Standing Seam Systems?
