Which snow guard systems are best suited for ADCO standing seam panels?
Standing seam metal roofs offer a clean, contemporary appearance along with impressive durability.
However, in areas prone to heavy snowfall, they can pose serious safety risks. Large sheets of snow and ice sliding off the roof can damage property or harm people and pets below. Industry professionals sometimes refer to these instances as roof avalanches. To mitigate this hazard, it's essential to select snow guards and snow retention systems that are compatible with the panel profile and attachment method. Panels with concealed fasteners require tailored solutions that ensure secure mounting and reliable performance. This blog series examines snow guard compatibility by panel type, highlighting reputable metal roofing brands to support informed and safe product selection.

Based in Hattiesburg, Mississippi, with production facilities in Lacombe, Louisiana, and Picayune, Mississippi, the company has served customers across the region for nearly six decades, building a reputation on reliability and craftsmanship. Founded in the 1960s as a small family business, ADCO has grown into a trusted manufacturer offering high-quality metal panels, trim, and structural components for residential, agricultural, and commercial projects. Whether it's barns, workshops, or pre-engineered buildings, ADCO combines local service with advanced roll forming technology to deliver consistent results. Their panels are made in the USA using prime-grade steel and protective coatings that meet modern standards for corrosion resistance, energy efficiency, and color retention.

Sem-Lok Nailstrip Panels
The Sem-Lok panel provides efficient installation and dependable performance across residential, architectural, light commercial, and industrial roofing projects. Measuring 16 inches wide with a 15/16-inch rib height, it creates sharp vertical lines that complement both classic and modern aesthetics. Its nailstrip snaplock design eliminates the need for mechanical seamers, streamlining installation while maintaining a watertight seal. These panels are available in 24- and 26-gauge Galvalume steel, manufactured to ASTM A792 standards under the AZ50 designation. The material offers excellent corrosion resistance and structural strength in challenging environments. Finish options include flat, ribbed (standard), and striated textures, giving designers flexibility in both appearance and performance. The Semcoat Plus Kynar coating ensures long-lasting color and weather protection. At the same time, the bare AZ-50 acrylic Galvalume finish provides a reflective, budget-friendly surface that supports energy savings. See the Snow Guards Compatibility Chart for ADCO Sem-Lok Nailstrip Standing Seam Metal Roofing Panels.
Adhesive-mounted polycarbonate snow guards are a suitable match for this panel, provided the adhesive is applied properly to prevent moisture-related issues such as refreezing or detachment. Recommended models include IceJax II, Snojax II, and SnoBlox Ace for broader coverage, and the Deuce, Ecojax, and IceJax I for smaller-scale use. For controlled snow release, the SnowBreaker and SnowBreaker 3M are effective options. Clamp-on snow guards and rail systems are not compatible with this panel due to its wide tapered seam design.
Verti-Lok Snaplock Panels
The Verti-Lok panel provides a streamlined standing seam solution for residential and light commercial roofing applications. Its snap-together configuration features a 1-inch rib height that delivers crisp architectural lines and a low-profile finish ideal for contemporary designs. Installed over solid decking with hidden clips, it provides a clean look and strong weather resistance. Each 24- or 26-gauge steel panel spans 13 inches, offering reliable strength and durability. Verti-Lok performs best on roofs with slopes of 3:12 or steeper, where its interlocking seams efficiently shed water and resist wind uplift. With multiple finishes and color options available, this panel combines the benefits of a standing seam system with simplified installation for faster project completion. See the Snow Guards Compatibility Chart for Verti-Lok Snaplock Standing Seam Metal Roofing Panels.
This panel supports a wide range of snow retention products, especially adhesive-mounted polycarbonate guards. Proper adhesive application is crucial to prevent moisture infiltration, which could lead to freezing or detachment. Larger models, such as the IceJax II, Snojax II, and SnoBlox Ace, are well-suited, along with smaller options like the Deuce, Ecojax, and IceJax I. For gradual snow release, the SnowBreaker and SnowBreaker 3M are reliable choices. The rib profile also accommodates clamp-on systems, including SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. Contractors can install these using stainless steel SnoBar clamps or aluminum RoofClamp units. Always test clamp fitment before placing an order to ensure compatibility.
Rock-Lok Mechanical Panels
The Rock-Lok Mechanical panel delivers robust performance and design flexibility for demanding roofing applications. Available in 12- or 16-inch widths and constructed from 24- or 26-gauge steel, it features a 2-inch vertical leg seam that enhances resistance to wind and weather. As one of the most versatile mechanical seam systems in the industry, Rock-Lok enables architects and contractors to meet a wide range of design and performance objectives. Panels are mechanically seamed after installation, forming a continuous, watertight joint that withstands extreme conditions while maintaining a refined appearance. The taller seam height improves drainage and wind uplift resistance, making this panel ideal for commercial, industrial, and upscale residential projects where durability is key. See the Snow Guards Compatibility Chart for Rock-Lok Mechanical Standing Seam Metal Roofing Panels.
This panel pairs well with adhesive-mounted polycarbonate snow guards, provided the adhesive is applied correctly to prevent moisture intrusion and potential detachment. Commonly used models include IceJax II, Snojax II, and SnoBlox Ace for larger areas, and the Deuce, Ecojax, and IceJax I for smaller installations. For controlled snow shedding, the SnowBreaker and SnowBreaker 3M are solid options. The rib design also supports clamp-on systems, such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. Contractors can install these using stainless steel SnoBar clamps or aluminum RoofClamp alternatives. Always test clamp fitment before finalizing your purchase.

Considerations for Adding Snow Guards to Standing Seam Roofs by ADCO
Using systems built for unusual roof shapes.
If your roof features curves, steep slopes, or unconventional layouts, you may require a custom snow retention system. Consult with the roofing manufacturer to determine the most suitable solution for your design.
Apply adhesives in the correct season.
Contractors should only install adhesive-mounted snow guards when temperatures are above 50°F to ensure proper curing, which typically takes 28 days. Water resistance begins within the first 24 hours. Do not use Surebond SB-190 on copper surfaces, as it is not compatible.
Order sample snow guards for test-fitting.
Our site allows you to order individual snow guard samples with no minimum purchase. Testing them on your roof helps verify fit and minimizes the chance of installation mistakes. Be sure to follow approved installation methods to maintain warranty coverage.
Account for regional snow load requirements.
Before selecting a snow retention system, consult your local building codes to determine the ground snow load for your area. Pad-style guards typically handle up to 45 pounds per square foot, while rail systems are better suited for heavier accumulations.
Verify that the guards suit your roofing system.
Choose snow guards that match your roof's material and profile. Our compatibility charts are a valuable resource for avoiding mismatches and ensuring a secure installation.
Adjust installation for complex roof details.
Modify snow guard placement to accommodate valleys, pitch changes, and other architectural features. Proper positioning in these areas helps maintain system effectiveness and reduces the risk of failure.
