Which snow guards provide the best performance for Westform Metals’ metal roof panels with exposed fasteners?

Metal roofs with exposed fasteners are commonly prone to abrupt snow and ice slides throughout the winter season.

The smooth surface of metal roofs causes snow and ice to slide off quickly, creating potential risks for people, pets, and property below. To address these dangers, we offer a range of snow retention products specifically designed for various roof types and materials. Our offerings include snow guards and rail systems that accommodate a wide range of roof pitches, panel designs, and weather conditions. Additionally, customers have access to our valuable resources, including comprehensive blog articles, clear installation instructions, and updated compatibility lists for many well-known roofing brands. In regions with heavy and consistent snowfall, these solutions are crucial for mitigating the risks associated with snow and ice accumulation, offering protection throughout the winter.

See the Snow Guards Compatibility Chart for Westform Metals Diamond Rib Screw Down Metal Roofing Panels.

The diamond rib resembles a standard PBR panel, but the ribs are much closer together. As such, none of our current product offerings are narrow enough to be compatible with this panel.

Weathershield 1

The Weathershield 1 metal roof panel, featuring a light steel cladding profile, is designed primarily for agricultural use. It features a low profile with .38 inch high rib on 8-inch centers, a solid lapping rib design that makes it well-suited for cladding arch rib and Quonset-style buildings. The panel is typically made from steel, providing durability and strength for various agricultural environments. The typical steel gauges used in such agricultural roofing panels generally range from 26 to 29 gauge for a balance of strength and weight. Overall, the Weathershield 1 panel offers a practical and robust solution for agricultural roofing needs, emphasizing coverage, weather resistance, and ease of installation on curved or arched structures.

Due to the unusual rib profile of this panel and the narrow flats, we recommend the Icejax I for attachment to this panel only. It will need to straddle one of the minor ribs for use. You can install it with adhesive or screws. See the Snow Guards Compatibility Chart for Westform Metals Weathershield 1 Screw Down Metal Roofing Panels.

Weathershield 2

The Weathershield 2 metal roof panel is a low-profile panel designed for both wall and roof applications.

The material options generally include steel, often with a protective coating such as Galvalume or painted finishes, with special colors available on request. The panel's construction and material choices aim to provide both strength and weather resistance suitable for diverse roofing needs.

The flats of this panel are wide, but the slight striations make this panel best for use with screw down guards. If you choose to use glue-down attachment methods, ensure that you apply a thicker layer of adhesive to seal any potential air gaps below the guards. Mechanical fasteners may flatten these striations under the guards, allowing for a better fit. See the Snow Guards Compatibility Chart for Westform Metals Weathershield 2 Screw Down Metal Roofing Panels.

WF-7/8-Inch Corrugated

The WF-7/8-Inch Corrugated metal roof panel from Westform Metals is a traditional and proven panel profile widely used for various building types such as schools and shopping malls. It is available in multiple gauges—26, 24, and 22 gauge. This panel features 0.90-inch high ribs on a standard corrugated rib spacing of 2.67 inches. The panel comes in standard lengths ranging from 1 to 40 feet. Material options include galvanized steel and Galvalume, with a selection of paint finishes, including SMP (silicone-modified polyester) and PVDF (polyvinylidene fluoride) premium coatings. The WF-7/8-Inch Corrugated panel provides durability, aesthetic appeal, and flexibility for commercial roofing applications. See the Snow Guards Compatibility Chart for Westform Metals WF-7/8-Inch Corrugated Screw Down Metal Roofing Panels.

This panel is distinguished by its unique wavy corrugated design, setting it apart from conventional exposed fastener roofing systems. Its profile enables customers to mount snow guards on the panel's raised ribs, which is a departure from typical roofing methods. The panel supports multiple snow retention options for those seeking effective solutions. Install the SnoCleat 2.67 snow guards by securely fastening them to the elevated ribs with 3-inch screws. Alternatively, customers may select the SnoBar or ColorBar snow retention systems, both of which use the ColorBracket 2.67 attachment bracket, the same bracket used by the SnoCleat 2.67. Each ColorBracket 2.67 features six attachment holes to enhance mounting strength. While only four screws are necessary for installation, users can opt to use all six screws per bracket—particularly in regions with harsh weather conditions—to ensure a robust and reliable installation.

WF-12-36

The WF-12-36 metal roof panel offers strength, a clean aesthetic, and a range of color options, making it suitable for pre-engineered metal buildings, post-frame structures, and agricultural applications. Its standard coverage width is 36 inches. The panel is available in multiple gauges, including 22, 24, and 26 gauge, with color options varying by gauge. Some premium PVDF colors are also available at an additional cost. This panel features 1.25-inch high ribs spaced 12 inches apart. Material options typically include various steel grades suitable for roofing. You can customize the exact steel type and finish options based on project needs and requests.

This flexibility makes the WF-12-36 panel a versatile choice for a range of commercial, industrial, and agricultural roofing needs. See the Snow Guards Compatibility Chart for Westform Metals WF-12-36 Corrugated Screw Down Metal Roofing Panels.

These Panels provide considerable versatility for installing snow guards, supporting a variety of types to suit different needs and preferences. Compatible options include screw-down models such as the SnoBar, ColorBar, SnoCleat PBR, and stainless steel SnowCatchers, which come in multiple designs like Standard, Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, and Kodiak. Most polycarbonate snow guards, aside from the Snojax I, can be attached using either adhesive or mechanical fasteners, while the Snojax I must be installed exclusively with mechanical fasteners. Use the Surebond SB-190 adhesive, which is specifically formulated for polycarbonate models, when installing them. Avoid applying this adhesive to metal pad-style guards. For optimal performance, place smaller snow guards centered between the minor ribs and aligned on the panels. Certain models, including the Snojax II and Icejax II, require off-center mounting by straddling either the left or right minor rib. It is essential to maintain consistent placement on the same rib throughout the entire installation. Snow guards and rail systems should never be attached directly to the high ribs; instead, they must be fastened through the panel's low flats into a solid substrate underneath to ensure a secure and stable installation.

WF-636 R

The WF-636 R metal roof panel features a reversed profile of the WF-636 Wall panel, designed to provide excellent waterproofing for roof applications while also offering a narrow rib aesthetic suitable for wall cladding. It has a coverage width of 36 inches and a rib depth of 1.5 inches. This panel accommodates various structural requirements on both flat and pitched roofs. It is commonly attached to light-gauge framing, open-web joists, or structural steel.

It also comes in a range of material options, with various colors available, including premium PVDF-coated colors, subject to extra charges, which provide flexibility in both appearance and performance. Overall, the WF-636 R panel combines structural robustness, waterproofing efficiency, and aesthetic versatility for commercial and industrial roofing and cladding applications. See the Snow Guards Compatibility Chart for Westform Metals WF-636 R Corrugated Screw Down Metal Roofing Panels.

This panel features 3.27-inch-wide flats, which limits the options for snow retention. We recommend the SnoBlox Deuce or IceJax I for glue-down installation or mechanical fastening. If you are looking for a way to allow snow and ice to shed but in a controlled, safer manner, then we recommend the SnowBreaker or SnowBreaker 3M. This panel is also compatible with the SnoBar and ColorBar rail systems when using the Tall ColorBracket attachment brackets.

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

Adjust Based On The Roofing Material

Tailor the spacing and arrangement of your snow guards depending on the roofing material in use. Softer metals, such as aluminum or copper, usually require guards to be placed closer together and in more rows than harder metals like steel. Always ensure that coatings and finishes are chemically compatible to avoid any negative reactions.

Coordinate Finishes with Your Roof’s Appearance

Select snow guards with finishes or coatings that complement your roof's color and design. Options include powder coatings and custom-colored inserts, which help create a unified, appealing appearance. While professionally applied finishes often offer greater durability, DIY options may be more affordable and quicker to use.

Attach Guards to Structural Supports

For maximum stability, mount snow guards directly onto the roof's supporting framework, such as rafters or metal purlins, rather than attaching them only to the roofing panels. If these structural supports are insufficiently strong, consider reinforcing them or using specialized adhesives to enhance the strength of the connection.

Apply Sealant to Prevent Leaks

When installing polycarbonate snow guards using screws, apply sealant evenly across the entire base of each guard. This method seals gaps effectively, enhances waterproofing, and reduces the likelihood of leaks.

Install Adhesive-Mounted Guards in Warm Weather

Schedule adhesive-based snow guard installations during late spring or early summer when daytime temperatures consistently exceed 50°F for several weeks. Warm weather is crucial for the proper curing of the adhesive; colder conditions slow the process. For example, SureBond SB190 becomes water-resistant about 24 hours after application, reducing rain-related bonding issues.

Check Placement Before Final Installation

Start by temporarily placing one or more snow guards on the roof to evaluate their fit and alignment. This fitment test helps detect potential installation problems before they become permanent.

Seek Guidance for Snow Guards for Unique Roof Shapes

Pad-style snow guards are generally less effective on curved, arched, or irregular roofs. For such roof types, opt for snow retention solutions specifically designed for unusual roof shapes and seek guidance from your roof panel manufacturer.
