Which snow guards work best with Kingspan's exposed-fastener roofing?
Metal roofs that rely on exposed fasteners are particularly susceptible to sudden slides of snow and ice during winter.
These events, often referred to as rooftop avalanches, can occur without warning and pose serious safety concerns. Because the panels have a smooth surface, snow and ice tend to break free in large sheets rather than gradually melting away. This sudden release can endanger people, pets, and property located beneath the roofline. To help manage these risks, we offer snow retention systems specifically designed for various roof designs and climate conditions. Solutions include both individual snow guard options and rail-style systems, adaptable to a variety of slopes and panel types. For added support, installers and property owners have access to our detailed manuals, blog articles, and updated compatibility charts covering major roofing brands. Whether in regions with light or heavy snowfall, these systems are essential for controlling how snow sheds from the roof.

JI Vulcasteel Roof Panel
The JI Vulcasteel Roof Panel is a robust insulated solution designed for pitched roofs, combining a trapezoidal outer steel sheet, mineral wool core, and a lightly profiled inner steel sheet. With insulation thicknesses available up to 7.9 inches (200 mm), it delivers outstanding fire resistance and acoustic performance, making it ideal for agricultural, industrial, service, and residential projects. The panel's trapezoidal ribs are spaced at 9.8 inches (250 mm) on center and stand 1.46 inches (37 mm) high, ensuring excellent structural strength and load distribution across wide spans. This composite design not only enhances durability but also simplifies installation, giving contractors a reliable option for demanding environments where safety and performance are non-negotiable. See the Snow Guards Compatibility Chart for Kingspan's JI Vulcasteel Screw Down Metal Roofing Panels.
Contractors can install polycarbonate guards with adhesive, except for the Snojax I, which requires mechanical fastening. For adhesive applications, use Surebond SB-190, the industry standard for this type of snow guard installation. Center the guards between the high ribs. Never mount guards and rails on the high ribs; instead, secure them to the flat sections to ensure lasting performance and stability. Because of this panel's insulated nature, mechanically fastened snow guards and bar or rail systems are incompatible.
K-Clad Roof Panel
The K-Clad Roof Panel is a single-component insulated system designed to simplify installation while delivering reliable thermal performance. With a cover width of 39.4 inches (1000 mm) and lengths ranging from 5.2 feet to 45.9 feet (1.6–14 m), it provides flexibility for a wide range of building types. Its PIR insulation core, available in thicknesses from 1.2 to 4.7 inches (30–120 mm), ensures excellent energy efficiency and condensation control. The trapezoidal ribs are spaced 13.1 inches (333.3 mm) on center, with a rib height of approximately 1.25 inches (32 mm), providing the panel with strong spanning capability and a clean profile. Offered in steel gauges of 22, 24, and 26, the K-Clad system strikes a balance between durability and installation speed, making it a versatile choice for warehouses, logistics facilities, and agricultural projects. See the Snow Guards Compatibility Chart for Kingspan's K-Clad Screw Down Metal Roofing Panels.
Contractors typically install polycarbonate snow guards using adhesive, but the Snojax I model requires mechanical fastening. When using adhesive, apply Surebond SB-190, the recognized industry standard for this type of installation. Position the guards in the flat areas between the ribs rather than on top of the high ribs to ensure proper load transfer and long-term durability. Because this panel is insulated, mechanically fastened guards, bars, or rail systems are not suitable.
KS1000RW Trapezoidal Roof Panel
The KS1000RW Trapezoidal Roof Panel is one of Kingspan's most widely used insulated roofing solutions, combining strength, efficiency, and ease of installation. It features a cover width of 39.4 inches (1000 mm) and is available in lengths ranging from 6.6 feet to 44.3 feet (2–13.5 m). Its PIR insulation core ranges between 1.6 and 5.5 inches (40–140 mm), ensuring compliance with modern thermal regulations while maintaining consistent energy savings. The trapezoidal ribs are spaced at 13.1 inches (333.3 mm) on center, with a rib height of 1.25 inches (32 mm), providing excellent load distribution and weather resistance. Available in steel gauges from 0.016 to 0.028 inches (0.4–0.7 mm), the KS1000RW panel is backed by third-party accreditations and fire performance approvals, making it a trusted solution for both new construction and refurbishment projects. See the Snow Guards Compatibility Chart for Kingspan's KS1000RW Trapezoidal Screw Down Metal Roofing Panels.
Installers can attach polycarbonate snow guards using adhesive, except for the Snojax I, which requires a mechanical connection. For adhesive applications, rely on Surebond SB-190, the proven product trusted across the industry. Always place guards between the ribs on the flat sections, never directly on the high ribs, to maintain structural integrity and performance. Due to the insulated design of this panel, mechanically fastened snow guards and rail systems are not compatible.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Kingspan
How Can I Fasten Snow Guards for Maximum Strength?
For the strongest hold, contractors anchor snow guards into structural components, such as rafters or purlins, rather than just the roof panels. Reinforcing the mounting area increases load capacity and ensures long-term stability.
Should I Test Fit Snow Guards Before Final Installation?
Doing a trial placement of snow guards before fastening them permanently helps confirm spacing and alignment. This step ensures a precise layout, resulting in a clean and professional finish.
How Does Roofing Material Affect Snow Guard Placement?
The type of roofing directly determines how contractors arrange snow guards. Softer metals, such as copper or aluminum, often require closer spacing and multiple rows, whereas harder materials, like steel, can accommodate wider gaps. Always verify that adhesives and sealants are compatible with the roofing material to prevent bonding issues.
When Is the Best Time to Install Adhesive-Mounted Snow Guards?
Adhesive-mounted snow guards perform best when installed in warmer conditions, typically from late spring through early summer, when temperatures are above 50°F. Warm weather accelerates curing, while cold weather can slow bonding. Adhesives like SureBond SB-190 typically resist moisture within 24 hours, reducing weather-related delays.
What Snow Guard Solutions Work Best for Unique Roof Shapes?
Roofs with distinctive designs, such as those featuring curved or arched profiles, often require custom snow guard solutions. Because standard models may not fit properly, contractors choose guards tailored to the roof's contours and consult the manufacturer.
Should I Apply Sealant Under Screw-Mounted Snow Guards?
Adding sealant beneath screw-attached polycarbonate snow guards helps close gaps, block water intrusion, and prevent leaks. This extra measure strengthens the installation and supports long-term performance.
How Can I Coordinate Snow Guard Finishes with My Roof Design?
Choose finishes that complement your roof's color scheme and architectural style. Powder-coated options or decorative inserts can enhance curb appeal and help the guards blend seamlessly. Professional coatings offer lasting durability, while DIY finishes may provide quicker and budget-friendly results.
