Which Snow Guards Work Best with Hercules' Exposed-Fastener Panels?
Exposed-fastener metal roofs are prone to releasing snow and ice in dangerous sheets when conditions are right.
Because the surface offers minimal friction, the entire layer can slide off at once rather than melting gradually. This sudden movement, often called a roof avalanche, can pose serious hazards to people, pets, vehicles, and anything beneath the eaves. To help reduce these risks, we supply snow-management products designed to work with a wide range of panel profiles and regional snow conditions. Depending on the project, installers may choose individual pad-style guards or continuous rail systems that span the roof for more uniform control. We also offer extensive educational resources, including an average of 3 weekly blog posts, installation instructions, compatibility tools, and manufacturer-specific guidance, to help property owners and contractors make informed decisions. Managing snow movement is essential for protecting a metal roof, whether the building is in a mild climate or an area that regularly experiences harsh winter weather.
About Hercules

R-Panel
The R-Panel features 12-inch rib spacing and a 1.25-inch rib height, creating a structural profile built for durability and long-term service. It is available in 26- and 24-gauge painted steel with a 40-year paint warranty, 26- and 24-gauge Galvalume with a 20-year warranty, and 29- and 26-gauge Galvalume with no warranty. The panel uses Sherwin-Williams WeatherX® coatings, offers Energy Star–qualified reflectivity depending on color, installs with an exposed-fastener system supported by a Purlin Bearing Rib leg, and provides 36 inches of coverage. WeatherX® finishes may also qualify for federal tax incentives. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings R-Panel Screw Down Metal Roofing Panels.
This panel works with a broad selection of our snow-retention products, allowing installers to match the system to the project's snow load and aesthetic needs. Stainless steel pad-style guards, such as the SnowCatcher series in Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang designs, can be mechanically fastened to the panel surface. Polycarbonate guards, including the SnoBlox Deuce, IceJax II, and SnoBlox Ace, can be installed with adhesive or screws, while the Snojax I must be mechanically attached. For breaking snow into smaller pieces, the SnowBreaker and SnowBreaker 3M offer effective control. In regions with snow loads above 45 PSF, or when a streamlined appearance is preferred, rail systems like SnoBar and ColorBar provide a strong, continuous solution. These systems use Tall ColorBrackets with butyl tape gaskets for secure installation. Because the panel has a textured finish, installers may need a thicker adhesive or sealant layer to ensure proper bonding.
Low Profile Panel
The Low Profile panel features 9-inch rib spacing and a ¾-inch rib height, offering a subtle, versatile appearance suitable for residential, agricultural, and light commercial projects. It comes in 26‑ and 24‑gauge painted steel with a 40‑year paint warranty, 26‑ and 24‑gauge Galvalume with a 20‑year warranty, and 29‑ and 26‑gauge Galvalume with no warranty. The panel features Sherwin-Williams WeatherX® coatings, may qualify for Energy Star reflectivity depending on color, installs with an exposed-fastener system, and provides 36 inches of coverage. The manufacturer uses steel with a minimum yield strength of 80 KSI, meeting the 1986 AISI standards. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings Low Profile Screw Down Metal Roofing Panels.
This profile is compatible with many of our snow-retention options, giving installers flexibility across different roof types. Polycarbonate guards such as the SnoBlox Deuce, EcoJax, and SnowBreaker fit neatly between the minor ribs. Metal guards, including the SnoCleat PBR and all SnowCatcher designs, fasten to the flat center section. Other models like the Snojax I and IceJax I span the minor ribs; the IceJax I supports adhesive or screw installation, while the Snojax I requires mechanical fastening. The panel also pairs well with Tall ColorBrackets, which support the ColorBar PBR and SnoBar PBR rail systems. This wide compatibility makes this panel a dependable choice for snow control in many climates.
Max Rib AG Panel
The Max Rib AG panel features 9-inch rib spacing and a ¾-inch rib height, creating a low-profile roofing and siding option commonly used in residential and post-frame construction. It is available in 26- and 29-gauge steel, finished with Sherwin-Williams WeatherX® coatings that meet Energy Star reflectivity requirements, and installs with an exposed-fastener system across a 36-inch coverage width. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings Max Rib AG Screw Down Metal Roofing Panels.
This panel supports a variety of our snow-retention products. Polycarbonate guards, such as the SnoBlox Deuce and SnowBreaker, fit between the minor ribs. In contrast, metal options, such as the SnoCleat PBR and decorative SnowCatchers, mount to the flat center section for added strength and visual appeal. Installers must mechanically fasten the Snojax I, while the IceJax I allows installation with screws or adhesive. For larger roof areas or regions with ground snow loads above 45 PSF, rail systems provide the most consistent performance. When used with Tall ColorBrackets and the appropriate fasteners, the ColorBar PBR and SnoBar PBR systems deliver reliable snow control across a wide range of climates.
Corrugated “S” Panel
The Corrugated “S” Panel features 2.5-inch rib spacing and a ½-inch rib height, creating the classic corrugated look used in both residential and commercial applications. It is available in 24-gauge painted steel with a 40-year paint warranty and in 29-, 26-, 24-, and 18-gauge Galvalume with a 20-year warranty. The panel comes with Galvalume® and Sherwin-Williams FluroponSR® coatings, may qualify for Energy Star reflectivity depending on color, installs with an exposed-fastener system, and provides 21.5 inches of roof coverage or 24 inches of wall coverage. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings Corrugated S Screw Down Metal Roofing Panels.
Because this panel's rib spacing is narrower than that of standard wavy corrugated profiles, our snow-retention products, including those designed for wavy corrugated panels, are not compatible with it. We recommend consulting the manufacturer for their approved snow-management options.
5-V Crimp Panel
The 5-V Crimp panel uses 12-inch rib spacing and a ½-inch rib height, giving it the traditional look associated with historic and coastal residential roofing. The manufacturer offers it in 29‑ and 26‑gauge Galvalume with a 20‑year warranty, applies Galvalume® coatings for corrosion resistance, uses an exposed‑fastener system for installation, and provides 24 inches of coverage. The manufacturer engineers the panel in accordance with the 1996 Cold‑Formed Steel Design Manual with the 1999 AISI supplement and states that oil canning is a visual characteristic, not a structural problem. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings 5-V Crimp Screw Down Metal Roofing Panels.
This profile supports a wide range of snow-retention solutions. Stainless steel SnowCatchers, available in Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang shapes, can be mounted individually. Installers can mount polycarbonate guards, such as the SnoBlox Deuce, IceJax II, and SnoBlox Ace, using screws or adhesive. Still, they must mechanically fasten the Snojax I. For controlled shedding, the SnowBreaker and SnowBreaker 3M help disperse snow and ice into smaller, safer pieces. In regions with snow loads above 45 PSF, or for those seeking a clean, modern appearance, rail systems like SnoBar and ColorBar offer strong, continuous protection. These systems rely on Tall ColorBrackets with butyl tape gaskets for secure installation.
Hercules Rib Panel
The Hercules Rib Panel features 9 ¾-inch rib spacing and a 1-inch rib height, creating a durable ribbed profile suitable for roofing and siding. It is available in 26-gauge Galvalume with a 20-year warranty, uses Galvalume® coatings, installs with an exposed-fastener system, and provides 29.25 inches of coverage. This product is one of the company's original ribbed panel designs. See the Snow Guards Compatibility Chart for Hercules Sheet Metal & Metal Buildings Hercules Rib Screw Down Metal Roofing Panels.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Hercules
How Can I Coordinate My Snow Guards with My Roof?
Choosing finishes that complement the roof's color and texture helps the guards blend in naturally. Durable powder-coated options maintain their appearance for years. At the same time, field-applied coatings offer a cost-effective way to customize the look.
Should I Use Sealant Under My Screw-Mounted Snow Guards?
A layer of sealant beneath screw-mounted guards helps seal small gaps, reduce the risk of leaks, and prevent moisture from entering the roof assembly. This added protection improves the overall reliability of the installation.
When Is the Best Time to Install Adhesive-Mounted Snow Guards?
Adhesive-mounted guards bond most effectively in warm weather, typically from late spring through early summer when temperatures stay above 50°F. Heat accelerates curing, and products like SureBond SB-190 usually become moisture-resistant within about a day.
Should I Test Fit Snow Guards Before Final Installation?
Temporarily placing the guards before fastening them allows you to confirm spacing, alignment, and layout. This simple step helps ensure a uniform pattern and a clean, professional finish once everything is secured.
What Snow Guard Solutions Work Best for Unique Roof Shapes?
Roofs with curves, arches, or other nonstandard contours often require guards that are selected or fabricated to match the exact shape. Standard models may not sit properly, making custom options and strict adherence to manufacturer instructions essential.
How Can I Fasten Snow Guards for Maximum Strength?
For the strongest attachment, fasten snow guards directly into structural framing such as rafters or purlins rather than relying solely on the roof panels. Securing them to these components increases load capacity and enhances long-term performance.
