Which Snow Guards Work Best with Garco Building Systems’ Exposed-Fastener Panels?
Metal roofs that use exposed fasteners are especially prone to sudden, heavy slides of snow and ice once winter sets in.
These fast-moving sheets, often called rooftop avalanches, can pose serious hazards along the edges of a building. Because exposed-fastener metal panels have smooth surfaces, snow tends to shed in large sections rather than melting gradually. When this happens, anything below the roofline, such as people, pets, vehicles, landscaping, or outdoor equipment, may be at risk. To help reduce these dangers, we offer snow retention systems designed to match specific panel profiles and local climate conditions. Installers can choose from individual pad-style guards or continuous rail systems, which makes it easier to adapt to different roof slopes and panel layouts. Our blogs, installation guides, compatibility charts, and manufacturer-focused resources help contractors and property owners select the right solution. Whether your region experiences light snowfall or heavy winter accumulation, snow retention is an important part of controlling how snow releases from your metal roof.
About Garco Building Systems and Its Exposed-Fastener Panels
Garco Building Systems produces advanced standing seam roofing as part of Ceco Building Systems within Cornerstone Building Brands. Garco now operates under the Ceco name and benefits from more than 135 years of combined experience in metal building engineering and roof system design. Ceco's expanded engineering resources, manufacturing capabilities, and Authorized Builder network support Garco's product lineup. Contractors use these panels on commercial, industrial, and institutional projects that require long-term reliability. Garco's systems continue to deliver strong performance backed by Ceco's technical support and Cornerstone's manufacturing strength.
PBR Metal Roof Panel
The PBR (Purlin Bearing Roof) panel, also known as an R-panel, is a versatile and widely used option. It features a bold, symmetrical rib pattern with deep, evenly spaced ribs and exposed fasteners suitable for both roofing and wall applications. The panel is 36 inches wide and includes ribs that are 1-1/4 inches tall with 12-inch on-center spacing. Ceco manufactures the PBR panel in two steel gauges: 24 gauge at 0.0276 inches thick and 26 gauge at 0.0179 inches thick. These options provide strong durability and long service life. Beyond its appearance, they engineered the PBR panel for enhanced structural performance. Reinforced flats between the ribs strengthen the building envelope and improve weather resistance. The panel also carries wind uplift ratings and qualifies for UL Class 90 construction under several construction numbers, which adds fire resistance and safety benefits. Installation is straightforward due to its efficient profile, which also improves diaphragm action for purlin stability. These qualities, combined with its clean look and weather-resistant design, make the PBR panel a strong choice for many roofing and wall system applications.

PBR panels offer excellent flexibility when installing snow guards and support a wide range of products and mounting preferences. They are compatible with many snow guard systems, including screw-down SnoBar and ColorBar rails, the SnoCleat PBR, and stainless steel SnowCatchers in designs such as the Standard Rectangle, Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, and Kodiak. Most of our polycarbonate snow guards can also be installed on these panels using either adhesive or mechanical fasteners. The only exception is the Snojax I, which requires mechanical fasteners. When using polycarbonate models, Surebond SB-190 is the adhesive needed because it is formulated specifically for these materials. Do not use this adhesive with metal pad-style guards. For best results, smaller snow guards should be placed between the minor ribs and centered on the panel. Certain models, including the Snojax II and Icejax II, must be mounted off-center. Hence, they straddle either the left or right minor rib and must remain aligned over the same rib throughout the installation. Installers should never attach individual guards or rail systems directly to the high ribs. The correct method is to fasten through the low flats and into solid structural support beneath the panel to ensure maximum strength and long-term stability.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Garco Building Systems
How Can I Fasten Snow Guards for Maximum Strength?
For the most reliable hold, secure snow guards directly to structural elements like purlins or rafters rather than relying solely on the roof panels. Fastening to these framing members increases load resistance and enhances long-term performance.
What Snow Guard Solutions Work Best for Unique Roof Shapes?
Roofs with curves, arches, or other nonstandard contours often require guards fabricated to match the exact profile. Off-the-shelf products may not sit properly, so installers should use custom-fit options and follow manufacturer recommendations for correct placement.
Should I Test Fit Snow Guards Before Final Installation?
Doing a preliminary fit on the roof allows installers to confirm spacing, alignment, and overall layout. This trial run helps ensure a consistent pattern and a polished final appearance for the guards.
Should I Use Sealant Under My Screw-Mounted Snow Guards?
Applying sealant beneath screw-mounted guards helps seal small gaps, limit water intrusion, and prevent moisture from working its way beneath the hardware. This added layer of protection improves the system's reliability and extends its service life.
When Is the Best Time to Install Adhesive-Mounted Snow Guards?
Adhesive-based guards bond most effectively during warm weather, typically from late spring into early summer when temperatures stay above 50°F. Heat accelerates curing, while cooler conditions slow it. Products like SureBond SB-190 usually become moisture-resistant within about a day, helping reduce weather-related setbacks.
How Can I Coordinate My Snow Guards with My Roof?
Choosing finishes that complement or closely match the roof’s color and texture helps the guards blend in visually. Powder-coated options offer durable, long-lasting color, while DIY coatings provide a faster, budget-friendly way to customize the appearance.
