The AppLok 100 panel is well-suited for various snow retention systems, particularly those using adhesive-mounted polycarbonate guards. To ensure long-term performance and prevent issues such as trapped moisture or ice buildup, it's crucial to apply the adhesive properly. Larger models such as IceJax II, Snojax II, and SnoBlox Ace deliver strong protection. At the same time, compact alternatives like IceJax I and SnoBlox Deuce also perform reliably. For added defense against sliding snow and ice, SnowBreaker and SnowBreaker 3M are dependable choices. However, due to the panel's wider trapezoidal rib, clamp-on snow guards and rail systems are incompatible.
AppLok 450 Panels
The AppLok 450 features a refined look and 1 17/32-inch tall seams that add visual depth. Designed for installation over solid decking, it uses concealed clips that simplify the process and allow the panels to adapt to temperature fluctuations. Offered in six standard finishes along with bare Galvalume, this profile maintains the clean, modern standing seam aesthetic favored in both residential and commercial construction. With panel widths ranging from 12 to 24 inches, it gives builders and designers the flexibility to match project size and style.

This panel supports a wide selection of snow retention solutions, with adhesive-mounted polycarbonate guards being particularly effective. Proper adhesive application is essential to ensure long-term performance and to prevent issues caused by trapped ice or moisture. Larger models, such as IceJax II, Snojax II, and SnoBlox Ace, provide robust protection. At the same time, smaller options, like IceJax I and SnoBlox Deuce, offer reliable results in more compact formats. For enhanced defense against sliding snow and ice, products like SnowBreaker and SnowBreaker 3M are excellent choices. The ribbed design of the AppLok 450 also allows for clamp-on systems, including SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar, which can be secured using stainless steel SnoBar clamps or aluminum RoofClamp attachments. To ensure proper fit and function, we recommend a test installation of the clamp.

Considerations for Adding Snow Guards to Standing Seam Roofs by Appalachian Metal Sales
Order sample snow guards to check the roof fit.
Individual sample units are available for purchase without a minimum quantity. Trying out a guard beforehand ensures it fits correctly and helps avoid expensive errors during installation.
Verify that guards suit your roofing system.
Ensure the snow guards you choose are compatible with your roof’s design and material. Use our compatibility charts for guidance.
Apply adhesives in the correct season.
Install adhesive-based guards when temperatures are above 50°F to allow proper curing, which generally takes around 28 days. They become water-resistant after 24 hours. Do not use Surebond SB-190 adhesive on copper roofing due to incompatibility.
Select roof finishes that complement your roof.
Enhance your roof’s look with powder-coated or custom-colored finishes. On-site DIY finishing may be quicker, though special colors may require additional lead time.
Plan layouts that balance snow loads.
To evenly distribute snow, place pad-style guards in staggered rows or install rail and bar systems in continuous lines, following our spacing recommendations.
Account for regional snow load requirements.
Review local building regulations to determine ground snow load values before choosing a system. Pad-style guards typically support up to 45 lbs per square foot; for heavier loads, we advise rail systems.
Using systems built for unusual roof shapes.
Roofs with curves or other unique designs may need tailored snow retention solutions. Always consult the roofing manufacturer for the most suitable setup.
Incorporate accessories to manage ice.
If ice movement is a concern, add IceStoppers to rail systems to reduce the risk of damage. These accessories help block ice sheets from sliding beneath rails, especially on taller standing seam roofs.
Adjust installation for complex roof details.
Modify snow guard placement to accommodate valleys, curves, or irregular roof features, ensuring consistent and effective coverage.
Follow installation methods approved for warranties.
To preserve your roof's warranty, use non-invasive mounting options, such as clamp-on or adhesive systems, for standing seam roofs. This practice helps prevent leaks caused by loose or damaged fasteners.
