Which snow guard systems are best suited for Coastal Metal Roofing Supply standing seam panels?
Standing seam roofs deliver a modern, streamlined look along with long-lasting durability. But in snowy regions, they can create safety concerns.
Large sheets of snow or ice sliding off the roof, often referred to as roof avalanches, can damage property or injure people below. To prevent this, contractors must carefully match snow retention systems to the roof's profile and the fastening method used. Concealed-fastener panels, in particular, require specialized solutions that ensure secure attachment and reliable performance. This guide reviews snow guard compatibility by panel type, highlighting Coastal Metal Roofing Supply's offerings to help contractors and homeowners make safe, informed choices.
Who Is Coastal Metal Roofing Supply?
Located in Ladson, South Carolina, Coastal Metal Roofing Supply has quickly become a trusted resource for contractors, builders, and homeowners across the Lowcountry. They designed their products to withstand the coastal climate, heavy rains, salt exposure, and hurricane-force winds. Standing seam panels are a cornerstone of their lineup, valued in Charleston and surrounding areas for their wind resistance, clean appearance, and long service life. In addition to standing seam, Coastal also produces R-panels and multi-rib panels, giving customers options for residential, agricultural, and commercial projects. Each panel is custom-cut to project specifications, reducing waste and simplifying installation.
Nail Strip Panels
Coastal's nailstrip standing seam panels are widely used in residential and light commercial construction thanks to their clipless, snap-lock design. Installation is straightforward: panels fasten through a slotted flange directly into a solid deck, eliminating the need for seamers or specialized tools. Standard dimensions include a 16-inch width and 1-inch seam height, producing a refined architectural look with dependable strength. Manufactured in 24- or 26-gauge steel with PVDF finishes such as Kynar 500, these panels resist fading, chalking, and coastal weathering. With over 40 color choices and warranties up to 40 years, they meet strict codes, including Miami-Dade and Florida Building approvals. See the Snow Guards Compatibility Chart for Coastal Metal Roofing Supply Nail Strip Standing Seam Metal Roofing Panels.
For snow retention, we recommend adhesive-mounted polycarbonate guards such as IceJax II, Snojax II, SnoBlox Ace, Deuce, Ecojax, and IceJax I. For gradual snow release, SnowBreaker and SnowBreaker 3M are effective. Clamp-on systems are not suitable due to the seam's wide tapered design.
Series 1000 Snap Lock Panels
The Series 1000 snap-lock system is a versatile choice for residential and light commercial roofs. Panels feature a 1.5-inch seam height and attach with concealed clips, creating a watertight finish that allows natural thermal movement. These panels are available in widths ranging from 12 to 20 inches, made from 24-gauge steel or .032 aluminum with high-performance PVDF coatings. These finishes resist UV damage and carry warranties up to 40 years. The system meets UL Class 90 wind uplift ratings and ASTM standards for air and water resistance, making it ideal for coastal conditions.

Snow retention options include adhesive-mounted polycarbonate guards (IceJax II, Snojax II, SnoBlox Ace, Deuce, Ecojax, IceJax I) and controlled-release devices, such as SnowBreaker. The rib profile also supports clamp-on systems, such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar, which contractors can install with stainless or aluminum clamps. Always confirm clamp fit before ordering.
Series 2000 Snap Lock Panels
Built for strength and durability, the Series 2000 snap-lock panels feature a bold 1.75-inch seam height and widths ranging from 12 to 20 inches. Commonly produced in 22- or 24-gauge steel or aluminum, contractors can secure these panels with concealed clips that allow for expansion and contraction. Optional pencil ribs, planks, or striations add design flexibility. With PVDF finishes from Sherwin-Williams Kynar 500, they resist fading and corrosion, backed by warranties up to 35 years. Certified to ASTM and UL standards, the Series 2000 is well-suited for coastal and high-wind environments.

Custom lengths up to 40 feet make them suitable for large-scale projects. PVDF finishes provide long-term resistance to corrosion and fading, supported by extensive warranties.

Considerations for Adding Snow Guards to Standing Seam Roofs by Coastal Metal Roofing Supply
Verify that the guards suit your roofing system.
Select snow guards designed to work with the specific material and profile of your roof. Compatibility charts are available to help prevent mismatches and ensure a secure installation.
Apply adhesives in the correct season.
Contractors should only install adhesive-mounted snow guards when the temperature exceeds 50°F. This practice allows proper curing, which generally takes 28 days. Initial water resistance develops within 24 hours. Avoid using Surebond SB-190 on copper, as it is not suitable for that surface.
Adjust installation for complex roof details.
Installers may need to alter snow guard placement to fit valleys, slope transitions, or other architectural features. Correct positioning in these areas helps maintain system performance and reduces the chance of failure.
Order sample snow guards for test-fitting.
You can request individual snow guard samples with no minimum order requirement. Trying them on your roof ensures proper fit and helps prevent installation errors. Always follow approved installation practices to maintain warranty protection.
Account for regional snow load requirements.
Check local building codes to identify the ground snow load in your area before choosing a system. Pad-style guards typically support up to 45 pounds per square foot, while we recommend rail systems for heavier snow conditions.
Using systems built for unusual roof shapes.
Roofs with curves, steep angles, or unconventional layouts may require specialized snow retention solutions. Consult your roofing manufacturer to determine the best option for your design.
