What are the best snow guard choices for Metroll exposed fastener steel roofs?
In winter, buildings with metal roofs featuring exposed fasteners often face problems when snow and ice suddenly slip off. This swift movement, usually called a roof avalanche, can cause several issues for the structure and the area around it.
The smooth surfaces of metal roofs allow snow and ice to slide off easily, creating hazards for people, pets, and nearby property. We offer snow retention systems designed for many of today's popular roofing types to address these concerns. These solutions include adjustable snow guards and customizable rails that can be adapted to suit different roof designs. They control how snow gathers on the roof by considering factors like roof slope, the kind of metal panels used, and local climate conditions. For proper installation and use, we provide a range of helpful resource materials, including blogs, guides, and an up-to-date list of compatible manufacturers. Snow retention systems are critical in regions that experience heavy snowfall, as they help minimize the dangers of ice accumulation and improve building safety. These systems offer dependable protection and peace of mind by reducing winter-related risks during severe weather.

PBR Panel
Metroll's PBR Panel is a metal panel system designed for roofing and wall applications, featuring an exposed fastener profile. Each panel covers a width of 36 inches and has a rib height of 1-1/4 inches, with ribs spaced 12 inches apart. Panel lengths are available from 3 feet up to 51 feet. Installation is suitable for roofs with a minimum slope of 1:12. The panels come in 26-gauge steel. However, customers can request 24 and 22-gauge options. Standard finishes include bare Galvalume, while additional color finishes with Super Durable SMP coatings are available by special order. The PBR Panel can be installed over solid substrates or open framing, making it adaptable to different building requirements. Metroll also offers a selection of trims and flashings designed to work with these panels, with the option for custom designs in bare or colored finishes.

With various color choices and versatility, the PBR Panel is well-suited for multiple architectural and construction needs. See the Snow Guards Compatibility Chart for Metroll PBR Screw Down Metal Roofing Panels.
This panel is highly adaptable for snow guard installation, making it ideal for various applications and user preferences. It is compatible with multiple types of snow guards, including screw-mounted rail systems such as SnoBar, ColorBar, and SnoCleat PBR. Additionally, the panel can accommodate several stainless steel SnowCatcher designs, including Standard Rectangle, Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, and Kodiak. Install most polycarbonate snow guards using either adhesive or screws, but fasten the Snojax I model with screws only. If you use adhesive for polycarbonate options, choose Surebond SB-190, as it is the recommended industry standard; however, this adhesive does not work with metal pad-style snow guards. Place smaller snow guards between the minor ribs in the center of the panel for optimal performance. Some models, like Snojax II and Icejax II, must be installed off-center, straddling either the left or right minor rib or mesa. Avoid mounting snow guards or rail systems directly on the high ribs; instead, they should be secured through the flat, low sections and anchored to a solid substrate for a reliable and durable installation.
7.2 LongSpan Panel
The 7.2 LongSpan Panel from Metroll is an exposed fastener panel with a rib-to-rib spacing of 7.2 inches and a rib height of 1 1/2 inches. Each panel provides a net coverage of 36 inches and can come in lengths ranging from 1 foot up to 51 feet. It is suitable for roofs with a minimum slope of 1:12. It is commonly manufactured in 26 gauge. However, 24-gauge options are available by special request. The panels come in a standard Galvalume Bare finish, with SMP finishes also available through special orders. Metroll offers standard universal trim and flashing and can arrange custom options for bare and colored finishes. A wide selection of colors is available, allowing for flexibility in design and matching. See the Snow Guards Compatibility Chart for Metroll 7.2 LongSpan Screw Down Metal Roofing Panels.
The 7.2 Panel is compatible with a range of snow management solutions designed to control snow and ice accumulation on your roof. The polycarbonate SnoBlox Deuce acts as a pad-style barrier, keeping snow and ice securely in place. Meanwhile, the SnowBreaker helps to fragment ice and snow into smaller, safer pieces as it slides off the roof. Installers can mount these snow guards using either screws or adhesive, and the SnowBreaker 3M model can be attached using 3M double-sided tape. Additionally, the 7.2 Panel works well with the galvanized SnoBar and the aluminum ColorBar snow rail systems. Both systems are mounted using the 1.5-inch-wide aluminum Tall Color Bracket, ensuring a reliable and efficient snow management setup.
7.2 ValuSpan Panel
The 7.2 ValuSpan Panel from Metroll has ribs spaced 7.2 inches apart and a rib height of 1-1/2 inches. Panels can be ordered from 1 foot up to 51 feet, providing a net coverage width of 28.8 inches. This panel is suitable for roof slopes as low as 1:12. It comes in a standard 26-gauge, with 24-gauge available as a special order. Installation is straightforward with exposed fasteners. The standard finish is Galvalume Bare, though an SMP finish can be requested. Metroll also offers a wide selection of colors and universal and custom trim or flashing options to complement the panels. See the Snow Guards Compatibility Chart for Metroll 7.2 ValuSpan Screw Down Metal Roofing Panels.
You can use the 7.2 Panel with several different products to help control snow and ice on your roof. The SnoBlox Deuce, made from polycarbonate, uses a pad-style design to keep snow and ice from sliding off. The SnowBreaker, on the other hand, breaks up the snow and ice into smaller, safer chunks as they fall. Install these guards using either screws or adhesive and attach the SnowBreaker 3M version with 3M double-sided tape. The 7.2 Panel also fits with the galvanized SnoBar and the aluminum ColorBar snow rails, which use the 1.5-inch wide aluminum Tall ColorBracket for secure installation and effective snow control.
CoroDek Panel
The CoroDek Panel is an exposed fastener panel suitable for roofing and wall cladding. Its distinctive curved center profile adds strength and rigidity, making it a reliable choice for various applications, particularly in commercial and agricultural settings. The panel features ribs spaced three inches apart and stands five-eighths of an inch in height. It comes in lengths ranging from one foot up to fifty-one feet, providing a net coverage width of thirty inches. The CoroDek Panel is typically produced in 26 gauge, with 24 gauge available by special order. Metroll finishes the panel in standard Galvalume Bare, but you can also request SMP finishes. You can install the panel flexibly over a solid surface or open framing. It works with Metroll's universal trim and flashing options, available in standard and custom choices. The panel is also offered in various colors to suit different project needs. See the Snow Guards Compatibility Chart for Metroll CoroDek Screw Down Metal Roofing Panels.
The distinctive corrugated shape of these panels means that most standard snow retention options, which need flat surfaces, are incompatible. To address this, we created the SnoCleat 2.67 system. This product can be mounted directly onto the high ribs of the panels using 3-inch screws, ensuring a strong and reliable hold. Because these wavy corrugated panels allow the brackets to span several ribs, they are not subject to the usual restrictions against attaching through the high ribs. For those interested in a continuous snow rail or snow fence, the SnoBar or ColorBar systems use the same 2.67 brackets as the SnoCleat. The ColorBracket 2.67 features six holes for mounting. Although only four screws per bracket are necessary, customers have the option to use all six for added strength, which is particularly beneficial in harsher climates.
EconoRib Panel
The EconoRib Panel from Metroll has a rib-to-rib spacing of 9 inches and a rib height of three-quarters of an inch. Each panel can be manufactured in lengths ranging from 1 foot up to 51 feet, providing a net coverage of 36 inches. It is suitable for roof slopes as low as 1:12. They typically make the panels from 29-gauge material. However, 26 and 24-gauge options are available by special order. The standard finish is Galvalume Bare, with an SMP finish offered for custom orders. The installation uses exposed fasteners, and a selection of standard universal trim and flashing is available, with custom options possible in both bare and colored finishes. You can choose from various colors to match different design preferences. The panel is also offered in various colors to suit different project needs. See the Snow Guards Compatibility Chart for Metroll EconoRib Screw Down Metal Roofing Panels.
This panel supports a wide range of snow retention systems, offering flexibility in installation techniques and material choices. Polycarbonate solutions like the SnoBlox Deuce and SnowBreaker fit between the panel's minor ribs. If you prefer metal options, mount screw-down products such as the SnoCleat PBR and any of the six SnowCatcher models on the flat central area of the panel. Other alternatives, including the Snojax I and Icejax I, are built to bridge the minor ribs. You can install the Icejax I using either adhesive or screws. At the same time, the Snojax I requires you to use mechanical fasteners for a secure hold. Additionally, the panel is compatible with Tall ColorBrackets and the necessary components to support either the aluminum ColorBar PBR or the galvanized SnoBar PBR snow rail systems. This broad compatibility ensures reliable snow retention and consistent performance in various weather and environmental conditions.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Metroll
Select Snow Guards That Match Your Roof's Design
Traditional flat snow guards may not be effective on roofs with curves or unconventional shapes. Choose products designed for unique roof profiles to ensure optimal snow retention and structural protection. Consulting with the roof panel manufacturer can help you identify the most suitable options.
Schedule Adhesive Applications During Warmer Months
When using adhesive to install snow guards, plan to do so in late spring or early summer, when daytime temperatures consistently stay above 50°F for several weeks. This temperature range is crucial for proper adhesive curing, as cooler weather can delay the process. Once the first 24 hours have passed, rain generally does not impact the adhesive's performance.
Coordinate Snow Guard Finishes with Roof Aesthetics
Pick snow guards with finishes or coatings that match or enhance your roof's appearance. Options such as powder coating or custom color inserts can create a cohesive and attractive look. Professional finishing services offer extra durability, but DIY methods may be more budget-friendly.
Secure Snow Guards to Structural Supports for Maximum Strength
For the strongest installation, attach snow guards directly to structural elements like wood or metal framing rather than just the roof panels. If the underlying structure isn't sufficient, consider reinforcing it with additional internal supports or specialized adhesive systems to improve stability.
Test Fit Snow Guards for Proper Alignment
Before proceeding with a full-scale installation, conduct a test fit to ensure all components align correctly with your roof's profile. Samples can help you identify and address any potential issues with fit or function before committing to the entire project.
Adjust Installation Methods Based on Roofing Material
Modify your installation technique according to the roofing material. Softer metals like aluminum or copper may require snow guards to be spaced closer together, with more rows than harder materials like steel. Also, confirm that all coatings are compatible to prevent adverse reactions between different metals.
Use Sealant to Improve Water Resistance
When attaching polycarbonate snow guards with screws, apply a layer of silicone sealant across the entire base. This step helps fill air gaps and enhances the system's protection against water infiltration.
