We get asked a lot about the performance difference between batten seam vs double lock standing seam metal roofing. At Spengler Industries, we don’t compromise on quality, which is why we don’t offer batten roof systems. While convenient and culturally ubiquitous, batten seam systems -especially snap on batten seam systems with a cap- fail to meet the high standards required for performance, longevity, and water-tightness. Instead, we recommend Double Lock Standing Seam Panels, which offer superior durability, strength, and longevity. Here’s why:
The History of Batten Seam Roofs
Batten seam roofing systems date back to medieval Europe, used for practical water-shedding on structures like barns and churches. These systems used copper, zinc, and lead, and while they were an effective option in their time, modern advancements such as Double Lock Standing Seam Panels have outperformed these older systems in terms of watertightness and structural integrity.
The Drawbacks of Batten Seam Roof Systems
The design of batten roof systems prioritizes ease of installation over long-term reliability. While they may seem convenient, these systems come with several critical flaws.
Exposed Fasteners: A Major Flaw
Batten seam systems often use exposed fasteners, which is considered a roofing malpractice. These fasteners create weak points where water can penetrate, leading to leaks and significant damage over time. In contrast, Double Lock Standing Seam Panels feature hidden fasteners, ensuring a completely sealed and watertight surface.
Lack of Longevity
The 25-35 year warranty typically offered with snap-on batten systems is a clear indication of their limited lifespan. Water-tightness is frequently compromised due to loose connections between panels and trim, increasing the risk of water damage. And the small print usually indemnifies them from any significant weather factor. We stand behind our products with a lifetime warranty because our systems are built for true durability.
Structurally Irrelevant Design
Although the name “batten seam” suggests the use of battens for support, many modern batten seam roofs no longer utilize actual battens. Instead, they rely on cosmetic caps that cover the seams, making them structurally irrelevant. This lack of true structural support further weakens the system, making it less capable of withstanding heavy snow loads or high winds. Without the strength of real battens, the roof system is more prone to failure under stress.
Unsuitable for Complex Roof Designs
Batten systems also struggle with intricate roof designs, such as dormers or skylights. Their seams are not tight enough to prevent water ingress. Double Lock Standing Seam Panels, on the other hand, are much better suited for complex structures, ensuring complete water-tightness even in the most challenging installations.
Above are some commonly seen metal roofing panel systems. 98% of the time, there is no substructure to support the batten, and even if there is, it still fails miserably. The truth is, any system pictured above—other than a properly installed double-locked standing seam roof—is not built to last and will inevitably cause issues.
Why do people still choose metal panels other than double locked standing seam? Because they’re “easy” to install and familiar. They prioritize a traditional look without the durability or performance that true Old World masters would demand. But you’re here because you understand that there’s a better solution—one that offers both timeless beauty and the reliability you need.
Snow Guards for Batten Seam Roofs: The Challenge of Heavy Snow Loads
One of the best ways we can show why batten seams are not viable choices for buildings expecting severe weather is how they handle snow loads.
We offer the best possible solutions for any project, even when faced with suboptimal roof systems like batten seam roofs. One notable example is a famous museum in Chicago, where we provided a batten seam snow guard system designed to handle the area’s heavy snow loads. While this system is truly the best in the world for batten seam roofs, it still falls short compared to the performance of a double lock standing seam system, especially in extreme conditions like those in Chicago.
Snow Guards: The Problem with Batten Seams
The snow guards we installed on this project were carefully designed to protect the roof from the dangers of snow sliding off in large sheets. However, installing snow guards on a batten seam roof requires roof penetrations, creating potential weak points for water ingress. Additionally, batten seam roofs are not strongly integrated with the rest of the roof structure, meaning heavy snow loads can exert enough force to rip the top off the battens, compromising the entire system.
Even with the best snow guard system, the inherent weaknesses of batten seam roofs—especially under heavy snow—make them less reliable. This is why we recommend, for long-term performance and permanent solutions, transitioning to a Double Lock Standing Seam system in areas prone to significant snowfall.

The Superior Solution: Double Lock Standing Seam
For regions like Chicago, with heavy snow and extreme weather conditions, Double Lock Standing Seam Panels offer unmatched durability and strength. Unlike batten seam roofs, double lock panels are fully seamed and integrated, making them far more resistant to snow loads, wind, and water infiltration. Virtually impervious, in fact! This roofing system provides a watertight, secure, and permanent solution for both modern and historic buildings.
To showcase the difference, here are some close up images of what a Double Lock Standing Seam system looks like,
For heavy snow areas, the best practice is clear: Double Lock Standing Seam is the ultimate roofing solution.
These detail pictures show clearly that no penetrations or roof damage occurs with the correct snow abatement systems on a standing seam roof. This is one reason among many why choosing the right roof from the beginning will net you the best overall results no matter the season or location.
Why Double Lock Standing Seam is the Superior Choice Over Batten Seam
For those seeking durability and superior performance, Double Lock Standing Seam Panels are the optimal solution. This system has been used for centuries in challenging environments and is the best choice for longevity and protection against the elements.
- No Exposed Fasteners
The Double Lock Standing Seam system eliminates the risk of exposed fasteners entirely. This prevents weak points and ensures the roof is fully sealed against water, wind, and debris. - Proven Longevity
Buildings with Double Lock Standing Seam roofs often last hundreds of years. This system’s longevity is proven, with older roofs still standing today, thanks to their robust design. - Durability in Harsh Environments
Double Lock Standing Seam panels are built to withstand extreme weather conditions, from heavy snow to high winds. The double-lock seam provides unparalleled strength that batten systems simply cannot match. - Precision Installation by Skilled Professionals
A properly installed Double Lock Standing Seam roof by skilled professionals ensures that it will remain watertight for generations.
