Which snow retention systems are best suited for Delta Metals' exposed-fastener metal roofing?

Metal roofing with exposed fasteners is especially susceptible to sudden releases of snow and ice during the winter, commonly known as rooftop avalanches.

The smooth finish of these panels allows snow and ice to build up and then slide off without warning, posing risks to people, pets, and property below. To help mitigate these dangers, we designed our snow retention systems to work across a wide variety of roof styles and materials. Customers can customize our snow guards and rail systems to fit specific panel profiles, roof pitches, and regional climate conditions. We also offer valuable resources, including blog articles, installation instructions, and updated compatibility charts for leading roofing brands. In areas with regular or heavy snowfall, these systems are essential for managing how and when snow and ice shed from the roof surface.

Delta Decking

Delta Decking by Delta Metals is engineered for strength, durability, and efficient installation, making it a robust alternative to traditional B-deck systems. The panels have a rib spacing of 6 inches and a rib height of 1.5 inches, providing excellent lateral diaphragm action that supports longer spans and reduces the need for additional structural bracing. Available in 20-gauge (.036-inch minimum thickness) and 18-gauge (.047-inch minimum thickness) galvanized steel, both options use A1011 CS Type B material with a G60 coating for corrosion resistance. The decking complies with ANSI/SDI RD-2017 standards. They reference it in the SDI Roof Deck Design Manual, Second Edition, for load and span calculations. It is also Factory Mutual compliant, with securement details accessible via FM Global. Contractors can fasten the panels using mechanical fasteners or puddle welds, subject to the engineer's approval. Additional specifications include a recommended 6-inch overlap, minimum end bearing of 1.5 inches, and interior bearing of 3 inches. Side lap screws are required if support spacing exceeds 5 feet. See the Snow Guards Compatibility Chart for Delta Metals Delta Decking Screw Down Metal Roofing Panels.

Because of the narrow nature of the low flats on this panel, it is compatible only with the SnowBreaker and our SnoBar and ColorBar systems when using the tall aluminum ColorBrackets for attachment. All other options are either too wide or too short for this unusual panel profile.

Delta Max Rib

The Delta Max Rib panel from Delta Metals combines a sleek, low-profile aesthetic with rugged performance, making it a versatile choice for residential, agricultural, and light commercial or industrial applications. Each panel offers a 36-inch coverage width with ribs spaced 9 inches on center and a rib height of ¾ inch, delivering a clean, modern look while maintaining structural integrity. Panels are available in 29-gauge steel with 26 color options and 26-gauge steel with 16 color options, allowing for design flexibility across a range of building styles. Custom-cut lengths range from 2 feet 6 inches to 40 feet, accommodating various project needs. The finish is backed by a Sherwin-Williams 40-year paint warranty, ensuring long-lasting protection and color retention. This panel is ideal for customers seeking both durability and visual appeal in their roofing or siding systems. See the Snow Guards Compatibility Chart for Delta Metals Delta Max Rib Screw Down Metal Roofing Panels.

Installers will appreciate how well this panel works with a variety of our snow retention products, giving them flexible options across different materials. Polycarbonate units, such as the SnoBlox Deuce and SnowBreaker, nest between minor ribs. At the same time, metal systems such as the SnoCleat PBR and all six SnowCatcher styles require screw attachment to the flat center area. Models like Snojax I and Icejax I span the minor ribs, with Icejax I offering both adhesive and screw mounting, and Snojax I relying solely on mechanical fastening. This panel also pairs seamlessly with our Tall ColorBrackets, which are compatible with either aluminum ColorBar PBR or galvanized SnoBar PBR rail systems. Thanks to this adaptability, the panel performs reliably under a range of snow conditions.

Legacy Panel

The Legacy Panel from Delta Metals offers a sleek, modern aesthetic at an affordable price, making it a popular choice for residential roofing and siding applications, as well as accent installations. Each panel provides 3 feet of coverage, streamlining installation and reducing material waste. Panels are available in 29-gauge steel with 26 color options and 26-gauge steel with 16 color options, giving homeowners and builders flexibility in both style and durability. Custom-cut lengths range from 2 feet 6 inches to 40 feet, accommodating a wide variety of project sizes. The finish is protected by a Sherwin-Williams 40-year paint warranty, ensuring long-term resistance to fading and environmental wear.

This panel is compatible with a broad spectrum of our snow guard systems, making it adaptable to diverse mounting methods and climate demands. You can also install Stainless steel pad-style options, such as the SnowCatchers in Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang designs. For added versatility, polycarbonate models like the SnoBlox Deuce, Icejax II, and SnoBlox Ace allow for either adhesive or screw attachment. The Snojax I, however, requires mechanical fastening and is not designed for adhesive use. To help mitigate the dangers of sliding snow and ice, the SnowBreaker and SnowBreaker 3M systems are ideal for fragmenting accumulated snow and ice into smaller, safer pieces. In regions with heavy snow loads (exceeding 45 PSF) or for those prioritizing a sleek, modern look, rail-style systems such as SnoBar and ColorBar offer a robust solution. These systems utilize Tall ColorBrackets paired with butyl tape gaskets to ensure a secure, watertight seal. Because of the panel's striated surface, installers may need to apply additional adhesive or sealant to achieve optimal bonding and fill any gaps between the snow guards and the panel.

Vintage Rib

The Vintage Rib panel from Delta Metals offers a timeless aesthetic with modern durability, making it ideal for residential, agricultural, and light commercial applications. Each panel provides a 36-inch coverage width with ribs spaced 9 inches on center and a rib height of ¾ inch, delivering a classic look with reliable performance. Panels are available in 29-gauge steel with 26 color options and 26-gauge steel with 16 color options, offering flexibility for both design and structural needs. Custom-cut lengths range from 2 feet 6 inches to 40 feet, accommodating projects of all sizes. The finish is protected by a Sherwin-Williams 40-year paint warranty, ensuring long-term resistance to fading and environmental wear. With its traditional profile and versatile application, the Vintage Rib panel is a dependable choice for customers seeking both style and strength. See the Snow Guards Compatibility Chart for Delta Metals Vintage Rib Screw Down Metal Roofing Panels.

This panel integrates effectively with a wide array of our snow retention systems, offering installers versatile solutions across multiple material types. Polycarbonate options like the SnoBlox Deuce and SnowBreaker fit snugly between the minor ribs. Metal alternatives, including the SnoCleat PBR and all six SnowCatcher models, must be mechanically fastened to the flat central section. Other designs, such as the Snojax I and Icejax I, span across the minor ribs. Icejax I accommodates both adhesive and screw installation, whereas Snojax I requires screw mounting. The Elite Panel is also compatible with Tall ColorBrackets, which support aluminum ColorBar PBR and galvanized SnoBar PBR rails. This broad compatibility makes the panel a reliable solution for snow load management in varying climates.

1/2 Inch Corrugated Panel

The ½ Inch Corrugated Panel from Delta Metals offers a refined, low-profile design that balances aesthetics with strength, making it ideal for architectural and residential applications. As an exposed fastener panel, it provides a cost-effective solution with easy installation and long-lasting performance. Panels are available in 26-gauge steel with 16 color options and 24-gauge steel with 12 color options, giving customers flexibility in both style and durability. Coverage varies by gauge: 26-gauge panels offer 34-inch coverage with double lap and 37-inch coverage with single lap. In contrast, 24-gauge panels provide 40-inch coverage with double lap and 42 inches with single lap. The panel features a 2.67-inch-on-center rib spacing and a ½-inch rib height, contributing to its sleek appearance and structural integrity. Custom-cut lengths range from 2 feet 6 inches to 40 feet, and the finish is backed by a Sherwin-Williams 40-year paint warranty, ensuring long-term color retention and protection against the elements. This panel is a smart choice for modern and traditional builds seeking a clean, durable exterior. See the Snow Guards Compatibility Chart for Delta Metals 1/2 Inch Corrugated Screw Down Metal Roofing Panels.

These Corrugated Panels bring a fresh look to roofing with their standout ribbed design. More than just aesthetics, they enable snow guards to be installed directly on the raised ribs, a rare advantage in the roofing world. While they support several snow retention systems, there are a few considerations. The new SnoCleat 2.67 snow guards attach firmly to the ribs using 3-inch screws. If you're looking for something stronger, the SnoBar and ColorBar systems are great alternatives, both using the ColorBracket 2.67, the same bracket as the SnoCleat 2.67. Each bracket includes six screw holes for extra holding power. Most installs only need four screws, but in areas with tough weather, using all six boosts reliability.

7/8 Inch Corrugated Panel

The 7⁄8 Inch Corrugated Panel from Delta Metals is a classic, high-performance metal panel that balances architectural appeal with structural durability. Its bold, refined profile makes it suitable for a wide range of applications, including modern and traditional roofing and siding. The panel is available in 26-gauge steel with 16 color options, 24-gauge steel with eight color options, and 22-gauge steel in weathering steel only (such as A606, Cold Rolled, and Bonderized). It features rib spacing of 2.67 inches on center and a rib height of 7⁄8 inch, offering a strong visual texture and excellent load-bearing capacity. Coverage varies by gauge and lap type: 26-gauge panels provide 32 inches of coverage with a single lap and 29 inches with a double lap. In comparison, 24- and 22-gauge panels offer 36-inch coverage with a single lap and 34 inches with a double lap. Panels are available in custom-cut lengths from 2 feet 6 inches up to 40 feet, and the finish is protected by a Sherwin-Williams 40-year paint warranty, ensuring long-term color retention and resistance to environmental wear. This panel is a durable, stylish solution for projects that demand both form and function. See the Snow Guards Compatibility Chart for Delta Metals 7/8 Inch Corrugated Screw Down Metal Roofing Panels.

The corrugated profile of these panels adds a modern twist to traditional roofing, setting them apart from standard exposed-fastener systems. This ribbed configuration allows for direct snow guard installation on the raised ribs, an uncommon capability among roofing styles. While the panels support various snow retention options, some limitations apply. The newly released SnoCleat 2.67 mounts securely to the elevated ribs using 3-inch screws. For enhanced performance, the SnoBar and ColorBar systems are also compatible, utilizing the ColorBracket 2.67, the same bracket used with SnoCleat 2.67. Each ColorBracket features six mounting holes to maximize strength. Although four screws per bracket are typically sufficient, installers may opt to use all six in high-impact weather zones for added durability.

PBR Panel

The PBR Panel from Delta Metals is a heavy-duty, commercial-grade solution designed for metal buildings and industrial facilities. Known as the standard workhorse for strength and versatility, it spans freely between purlins up to 5 feet, making it ideal for large-scale open-frame structures. Each panel offers a 36-inch coverage width with ribs spaced 12 inches on center and a rib height of 1¼ inches, delivering exceptional load-bearing capacity and durability. Panels are available in 26-gauge steel with 26 color options and in 24-gauge steel with 16 color options, offering both aesthetic flexibility and structural performance. Custom-cut lengths range from 2 feet 6 inches to 40 feet, and the finish is backed by a Sherwin-Williams 40-year paint warranty, ensuring long-term protection against fading and environmental wear. This panel is a reliable and cost-effective choice for demanding commercial applications. See the Snow Guards Compatibility Chart for Delta Metals PBR Screw Down Metal Roofing Panels.

This panel works with a wide variety of snow retention systems, giving installers the flexibility to match solutions to local weather and mounting preferences. Stainless steel pad-style guards, like the SnowCatcher series in styles such as Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang, fasten directly to the panel. Polycarbonate options, including SnoBlox Deuce, Icejax II, and SnoBlox Ace, support both glue and screw installation, while the Snojax I must be mechanically attached. To help break up snow and ice into safer, smaller pieces during release, the SnowBreaker and SnowBreaker 3M systems are highly effective. For high-snow-load areas or customers seeking a modern look, rail systems like SnoBar and ColorBar offer a strong, clean solution. These systems use Tall ColorBrackets with butyl tape gaskets for a secure fit. Because of the panel's textured surface, you may need to apply a thicker layer of adhesive or sealant to ensure proper bonding.

Delta Trap 438

The Delta Trap 438 panel from Delta Metals combines bold aesthetics with industrial-grade strength, making it ideal for commercial buildings, privacy fencing, accent walls, and residential wainscoting. Its trapezoidal profile delivers exceptional rigidity and visual impact, especially in exposed fastener applications. Panels are available in 26-gauge steel with multiple color options and 24-gauge steel with limited color availability (contact sales for details). The panel features a 4.25-inch-on-center rib spacing and a ⅞-inch rib height, offering a structured, corrugated look with reliable performance. Coverage varies by gauge: 34 inches for 26-gauge panels and 38.25 inches for 24-gauge panels. Custom-cut lengths range from 2 feet 6 inches to 40 feet, and the finish is backed by a Sherwin-Williams 40-year paint warranty, ensuring long-term durability and color retention. This panel is a versatile choice for projects that demand both strength and style. See the Snow Guards Compatibility Chart for Delta Metals Delta Trap 438 Screw Down Metal Roofing Panels.

Due to the narrow spacing of the flats on this panel, we do not currently offer a compatible snow retention system for it.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Delta Metals

Should I Apply Sealant Under Screw-Mounted Snow Guards?

Using a generous amount of sealant beneath screw-fastened polycarbonate snow guards helps close gaps, improve water resistance, and minimize future leaks. This added measure strengthens the overall installation and enhances its longevity.

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

Choose finishes that complement your roof's color scheme and architectural features. Options such as powder coating or custom inserts can enhance aesthetics and help the guards visually integrate with the roof. Professional-grade coatings offer long-term durability, while DIY alternatives may deliver faster results at a lower cost.

Should I Test Fit Snow Guards Before Final Installation?

Laying out snow guards in advance allows you to verify spacing and alignment before committing to installation. This step makes it easier to adjust placement and ensures a more polished, professional outcome.

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 to the roof panels. Reinforcing the attachment area or combining adhesive with screws can increase load resistance and improve overall stability.

What Snow Guard Solutions Work Best for Unique Roof Shapes?

Non-standard roof designs, such as arched or curved profiles, often need custom snow guard solutions. Standard models may not conform properly, so it’s wise to select guards designed for the roof’s specific geometry and consult the manufacturer for recommendations.

How Does Roofing Material Affect Snow Guard Placement?

Roofing type significantly influences snow guard layout and spacing. Softer metals like aluminum or copper may require closer spacing and multiple rows. At the same time, harder materials like steel can support wider gaps. Always confirm that adhesives and sealants are compatible with the roof surface to prevent bonding issues or damage.

When Is the Best Time to Install Adhesive Snow Guards?

Adhesive snow guards perform best when installed in warm conditions, typically late spring through early summer, when temperatures exceed 50°F. Heat promotes proper curing, while cold can slow the process. Products such as SureBond SB-190 often become moisture-resistant within a day, helping reduce weather-related delays.
