Which snow retention systems are best suited for Borga Steel’s exposed-fastener metal roofs?

Metal roofing with exposed fasteners is especially vulnerable to rapid snow and ice release during winter, often referred to as rooftop avalanches.

Due to the smooth finish of these panels, snow and ice can build up and then slide off suddenly, posing risks to people, pets, and property below. To help mitigate these dangers, we offer snow retention solutions specifically designed for various roof styles and climates. Our snow guards and rail systems are compatible with a wide range of panel profiles and roof pitches. We also provide valuable resources like our installation guides, blog articles, and updated compatibility charts for leading roofing brands. In areas with frequent or heavy snowfall, these systems play a vital role in managing how and when snow and ice shed from the roof surface.

With options such as mechanically seamed (SRS) and snap-together (SDP) panels, Borga offers flexible roofing solutions supported by regional expertise and responsive customer service.

Super Panel

The Super Panel is designed for strength and versatility, making it an ideal choice for roofing and siding applications across agricultural and commercial buildings. Featuring 1.375-inch ribs spaced 12 inches apart, it offers excellent spanning ability and a clean, symmetrical appearance. Available in 24 or 26 gauge Galvalume or galvanized steel, this panel supports lengths of up to 45 feet and performs well on low-slope roofs with a slope of ½:12. It's compatible with standard PBR profiles. It comes in finishes such as SMP paint, bare G90, Galvalume, or Zincalume. See the Snow Guards Compatibility Chart for Borga Steel Super Panel Screw Down Metal Roofing Panels.

This panel supports a wide array of our snow retention systems. Compatible options include screw-fastened snow rails, such as SnoBar and ColorBar, as well as the SnoCleat PBR and stainless steel SnowCatchers in decorative styles like Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, Kodiak, and Standard. Most polycarbonate snow guards can be installed with either adhesive or screws, though the Snojax I must use mechanical fasteners. For adhesive-mounted guards, we recommend Surebond SB-190. Note that this adhesive is not suitable for metal pad-style guards. Unlike traditional PBR panels, the Super Panel features a single minor rib between major ribs. For optimal performance, installers should offset smaller guards to one side and maintain consistent alignment. Contractors can center models like Snojax II and Icejax II by straddling the minor rib. Always mount guards on the flat sections, not the high ribs, and anchor them into a solid substrate for long-term reliability.

Classic Panel

The Classic Panel offers a bold, corrugated aesthetic with ⅞-inch ribs spaced tightly at 2.67 inches, creating a textured surface that suits both architectural and industrial applications. With a 32-inch coverage width, it's effective for roofing and siding and performs well on slopes as low as 1:12. Available in 24 and 26-gauge steel, this panel meets UI 90 structural standards. Its retro-inspired design makes it a standout choice for projects that blend style with function. See the Snow Guards Compatibility Chart for Borga Steel Classic Panel Screw Down Metal Roofing Panels.

This panel's distinctive wavy profile allows snow guards to be mounted directly onto the raised ribs, a less common but effective method. For snow retention, the SnoCleat 2.67 is a popular option, secured with 3-inch fasteners. Alternatively, contractors can install the SnoBar and ColorBar systems using the ColorBracket 2.67, which shares compatibility with the SnoCleat. Each bracket includes six mounting holes for added strength. While four screws are sufficient for standard installations, using all six is recommended in regions with severe winter conditions for enhanced durability.

Borga Panel

Borga Steel designed the Borga Panel for affordability and utility, featuring ¾-inch ribs spaced 6 inches apart and offering 36 inches of coverage per panel. Commonly used in mini-storage units, interior liners, and general-purpose roofing and siding, it's available in 24 and 26-gauge Galvalume or galvanized steel. It accommodates roof slopes down to 1/2:12 and comes in finishes such as SMP paint, bare G90, Galvalume, and Zincalume. Its simple profile and wide coverage make it a go-to choice for builders seeking efficiency. See the Snow Guards Compatibility Chart for Borga Steel Borga Panel Screw Down Metal Roofing Panels.

Although the panel flats are relatively narrow at around 3.5 inches, there are still several effective snow retention options. Pad-style polycarbonate guards, such as the Ace, Deuce, and Icejax I, are suitable for holding snow and ice in place. For controlled shedding, SnowBreaker and SnowBreaker 3M models help break up snow into smaller, safer pieces. Contractors can install these guards using screws or Surebond SB-190 adhesive. Additionally, Tall ColorBrackets allow for the mechanical attachment of SnoBar and ColorBar snow rail systems to the U-Panel.

HR345 Panel

The HR345 Panel offers a combination of structural strength and modern design, featuring 1.5-inch ribs spaced 6.9 inches apart with a coverage width of 34.5 inches. Ideal for industrial roofs, walls, and carports, it supports slopes as low as 1:12. Available in 24- and 26-gauge steel, this panel meets UI 90 standards. It comes in SMP finishes or unpainted G90, Galvalume, and Zincalume finishes. Its deep ribs and broad span make it a durable and visually appealing choice for demanding environments. See the Snow Guards Compatibility Chart for Borga Steel HR345 Panel Screw Down Metal Roofing Panels.

Due to its narrow 1.5-inch panel flats, snow guard placement requires careful consideration. The SnoBlox Deuce is a reliable pad-style polycarbonate guard that contractors can install using screws or adhesive to prevent snow and ice from accumulating. For controlled shedding, the SnowBreaker helps disperse snow into smaller chunks, making it easier to remove. This panel also supports galvanized SnoBar and aluminum ColorBar rail systems, which can be mounted using the 1.5-inch-wide aluminum Tall ColorBracket for secure attachment.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Borga

How Can I Coordinate Snow Guard Finishes with My Roof Design?

Choose finishes that complement your roof's color scheme and architectural features. Powder-coated options or custom inserts can enhance the aesthetic and help the guards blend seamlessly with the roofline. Professional-grade coatings offer long-term resilience, whereas DIY alternatives may provide faster and more cost-effective results.

Should I Test Fit Snow Guards Before Final Installation?

Test fitting snow guards in advance allows you to verify spacing and alignment before securing them. This preliminary step helps refine positioning and contributes to a polished, professional appearance.

How Can I Fasten Snow Guards for Maximum Strength?

For optimal strength, secure snow guards to structural supports, such as rafters or purlins, rather than just the roof panels. Reinforcing the attachment area or combining mechanical fasteners with adhesive can increase load resistance and enhance durability over time.

What Snow Guard Solutions Work Best for Unique Roof Shapes?

Non-standard roof designs, such as arched or curved profiles, often require custom-fit snow guards. Standard models may not conform properly, so selecting guards tailored to the roof’s geometry and consulting the manufacturer is recommended.

Should I Apply Sealant Under Screw-Mounted Snow Guards?

Adding a substantial coating of sealant beneath screw-mounted polycarbonate snow guards helps close gaps, minimize moisture entry, and prevent leaks. This step strengthens the overall installation and improves long-term reliability.

How Does Roofing Material Affect Snow Guard Placement?

The type of roofing significantly influences snow guard layout and spacing. Softer metals, such as aluminum or copper, may require closer spacing and multiple rows, whereas harder materials, like steel, can accommodate wider gaps. Always ensure adhesives and sealants are compatible with the roofing surface to avoid bonding issues.

When Is the Best Time to Install Adhesive-Mounted Snow Guards?

Adhesive-applied snow guards bond best in warmer conditions, typically late spring through early summer when temperatures exceed 50°F. Heat accelerates curing, while cold can slow or impair adhesion. Products like SureBond SB-190 often become moisture-resistant within a day, helping reduce weather-related delays.
