What Are the Best Snow Guards for Metal Roofs?

When winter nears, buildings with exposed fastener metal roofs encounter distinct seasonal challenges, particularly from the sudden movement of snow and ice, also referred to as roof avalanches. The smooth surfaces of these roofs make it more likely for snow and ice to slide off quickly, creating potential dangers for people, pets, and nearby property. Engineers have developed specialized retention systems with adaptable snow guards and customizable rail systems to address these risks for various roof designs. These solutions effectively manage snow buildup by considering the roof's slope, the type of panels used, and the area's specific climate conditions. We provide comprehensive support materials, including instructional blogs, digital guides, and an up-to-date list of compatible manufacturers, and we regularly expand these resources to ensure proper product use. These systems are beneficial in regions that experience heavy snowfall, as they help minimize the hazards associated with frozen precipitation and improve overall structural safety. Reducing winter-related risks offers dependable protection and greater peace of mind during severe weather.

Corten Roofing is a division of Western States Metal Roofing that specializes in manufacturing and supplying weathering steel panels for roofing and siding applications. The standout feature of Corten steel is its ability to develop a rusted patina over time, giving buildings a distinctive, rustic appearance and acting as a protective layer to enhance the material's resistance to further corrosion. Western States Metal Roofing, established in 1996 originally as Western States Decking, Inc., began as a distributor of Verco metal decking products and later expanded into producing its own metal roofing and siding solutions. Over the years, the company has built a reputation for leading the market in weathering steel products, including panels that provide the look of aged metal. Corten Roofing continues this legacy by offering a broad selection of panels suitable for residential and commercial projects. Their offerings cater to architects, builders, and homeowners who desire durable and visually appealing materials. Product options include corrugated panels, standing seam roofing, and structural components crafted from ASTM-grade weathering steel, such as A606-4, A588, and A847. By purchasing Corten steel in large quantities, the company can provide competitive pricing, fast shipping, and custom panel sizes to meet specific project requirements. Unlike pre-weathered alternatives, Corten Roofing's panels are shipped in their original state and naturally develop their protective patina after installation. The manufacturer recommends a minimum roof slope of 3:12 for best results and longevity. Known for its quality products, competitive prices, and knowledgeable service, Corten Roofing has established itself as a prominent supplier in the weathering steel roofing and siding industry.

7/8 Inch Corrugated

The 7/8 Inch corrugated panel made from Corten steel is a popular choice for roofing and wall applications, thanks to its distinctive deep, wavy corrugations that provide impressive structural strength and impact resistance. When delivered, the panels have a dull gray appearance and are not pre-rusted; instead, they naturally develop the well-known Corten patina as they are exposed to the elements, requiring no special treatment to start the rusting process. The manufacturer produces these panels from A606-4 Corten steel in 20 and 22-gauge thicknesses. Each panel has a rib height of 7/8 Inch with ribs spaced 2.67 inches apart, offering an overall width of 39 inches. For roofing, the coverage area is 34.67 inches, while for wall installations, it is 37 inches. Panel lengths can range from 1 foot up to 52 feet. Installation is straightforward, utilizing exposed fasteners—preferably stainless steel screws with painted brown heads—over a solid substrate. It's important to note that these panels are recommended for roofs with a minimum slope of 3:12 and are unsuitable for flatter roofs where water might pool. Perforated versions of the Corten panel are also available for those seeking additional design options. They can create partially open, translucent screens for exterior and interior spaces. Overall, the 7/8 Inch corrugated Corten panel offers a durable and visually appealing solution that evolves, making it a versatile choice for various architectural and industrial projects.

The distinct corrugated shape of these panels makes them incompatible with most standard snow retention systems, which typically require flat surfaces for installation. To address this, we provide a solution known as the SnoCleat 2.67. This product can be mounted directly onto the high ribs of the panels using 3-inch screws, ensuring a strong and reliable attachment. Because these wavy corrugated panels allow the brackets to span across multiple ribs, they are not subject to the usual restrictions against screwing through the high ribs. SnoBar and ColorBar use the same 2.67 brackets as the SnoCleat for those interested in a continuous snow rail or snow fence system. The ColorBracket 2.67 features six holes, and while only four screws per bracket are necessary, customers have the option to use all six for increased mounting strength, which is especially beneficial in harsher weather conditions.

R Panel/PBR Panel

They designed their R and PBR panels for residential and commercial roofing and siding projects. These panels are available in A606-4 (Corten) steel at 22 gauge and bare cold rolled steel at 22, 24, and 26 gauge thicknesses. When first delivered, the panels have a dull gray appearance and are not pre-rusted; instead, they naturally develop a rusted patina when exposed to the elements over time. Each panel features ribs spaced 12 inches apart and stands 1.25 inches high, providing a coverage width of 36 inches. Customers can order these panels from one foot up to 52 feet. Contractors install them using exposed fasteners—ideally stainless steel with a brown-painted screw head—over a solid substrate. For roofing applications, they recommend a minimum slope of 3:12 to prevent issues with standing water, and these panels are unsuitable for flatter roofs. In addition to standard panels, perforated options are offered for creative uses such as fencing, shade structures, and architectural accents, allowing for partial visibility and light passage. Digital samples and 3D textures are available to preview the look of the panels before purchase, making it easy to achieve the distinctive appearance of rusted metal while avoiding common problems associated with rust.

The panel design offers remarkable adaptability for snow guard installation, making it suitable for various project needs. This system works well with multiple snow guards, such as our screw-fastened rail systems and stainless steel SnowCatchers. Because of the Corten coating on these panels, we do not recommend using adhesive-mounted polycarbonate snow guards. The manufacturer designed the Corten coating on these panels to patina and rust. We do not have testing data for Surebond SB-190 or 3M double-sided tape on this coating. We cannot guarantee their performance or the outcome if you try it. These panels also contain nickel, chromium, manganese, and copper elements. Of these elements, copper is especially incompatible with Surebond SB-190 adhesive; using this glue could cause premature damage to the panels. Screw-down installations are the only ones we recommend for this style of panel. For the best results, place smaller snow guards between the minor ribs at the center of the panel. Some models, including the Snojax II and Icejax II, must be positioned off-center, straddling either the left or right minor ribs or mesas. It is essential to avoid attaching snow guards and rail systems directly to the high ribs of the panel; instead, they should be secured through the low, flat areas to ensure optimal stability and strength by anchoring them to a solid base underneath.

Western Rib

The Western Rib Panel, also known as the 7.2 Panel, is recognized as the most durable option produced by Corten Roofing. People frequently use it for fencing and siding projects, although it is also suitable for roofing. These panels are made from A606-4 (Corten) steel in 20 or 22 gauge or bare cold rolled steel in 22, 24, or 26 gauge. When delivered, the panels are dull gray and not pre-rusted; they will naturally develop a rusted patina once exposed to the elements. Each panel features ribs spaced 7.2 inches apart and stands 1.5 inches tall, providing a coverage width of 36 inches. Panel lengths can range from one foot to 52 feet, and installation requires a solid substrate. Roofers attach these panels with exposed fasteners, and the manufacturer recommends using stainless steel screws with a brown painted head for the best look. A minimum slope of 3:12 is necessary for roofing applications, as these panels are unsuitable for flatter roofs where water may collect. In addition to their strength and weathered appearance, perforated versions are available for projects that require a see-through effect, such as screens or decorative architectural features. Customers can request Digital samples and 3D textures to help with project planning. See the Snow Guards Compatibility Chart for Corten Roofing Western Rib Exposed Fastener Metal Roofing Panels.

Of these elements, copper is especially incompatible with Surebond SB-190 adhesive; using this glue could cause premature damage to the panels. Screw-down installations are the only ones we recommend for this style of panel. The polycarbonate SnoBlox Deuce uses a pad-style guard to keep snow and ice in place. At the same time, the SnowBreaker breaks up falling snow and ice into smaller, safer pieces. Additionally, the Western Rib is compatible with the galvanized SnoBar and the aluminum ColorBar snow rails. Both systems use the 1.5-inch wide aluminum Tall ColorBracket for secure attachment.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Corten Roofing

Adapting to Unique Roof Shapes

Conventional flat-based snow guards often fail on curved or unusually shaped roofs. Use retention solutions engineered explicitly for non-standard surfaces to address these architectural challenges to maintain snow control and structural soundness. It is advisable to consult with the roof panel manufacturer to obtain tailored recommendations for these scenarios.

Material-Specific Installation Methods

The type of roofing material greatly influences installation strategy. Softer metals like aluminum or copper typically need more closely spaced snow guards than harder materials like steel. Additionally, applying protective coatings can help prevent adverse chemical reactions when combining different metals in retention systems.

Timing for Adhesive Applications

For adhesive-mounted systems, plan installations during late spring or early summer when temperatures consistently exceed 50°F for at least four weeks. This temperature range ensures adhesives cure properly, while colder conditions can slow the process. After 24 hours, rain generally does not affect the adhesive's performance.

System Compatibility and Pre-Installation Test Fits

Before installing, confirm that all retention components are compatible with the specific roof profile. Trial installations may be necessary to guarantee a proper fit and reliable performance.

Aesthetic Considerations

Select snow guards that complement the roof's appearance, such as those with color-matched finishes or powder coatings. While professional finishing services offer durable and visually appealing results, they may be more expensive than do-it-yourself alternatives.

Reinforcing Attachment and Structural Suitability

Fasten mechanically attached snow guards directly to solid substrates such as wood or metal supports rather than only to the roof panels. Where structural support is lacking, internal blocking or adhesive-based solutions may be required to ensure secure installation.

Optimizing Sealant Use

When installing screw-down polycarbonate guards, apply silicone sealant across the entire base to seal air gaps and enhance waterproofing.
