Snow Guard Options for Pacific Building System’s Exposed-Fastener Metal Panels

See the Snow Guards Compatibility Chart for Pacific Building Systems Screw Down Metal Roofing Panels.

Which Snow Guards Work Best with Pacific Building System’s Exposed-Fastener Panels?

Exposed-fastener metal roofs often release snow and ice quickly when temperatures shift.

Their smooth surface gives snow very little grip, so large sheets slide off rather than melting gradually. This sudden movement, sometimes called a roof avalanche, can pose hazards to people, pets, vehicles, and anything located near the edges of the building. To help reduce these risks, we offer snow retention products that match a wide range of panel profiles and regional snow conditions. Installers can select individual pad-style guards or continuous rail systems that spread holding strength across the roof. We also supply a wide range of educational resources, including installation guides, compatibility information, manufacturer-specific charts, and detailed blog content to support proper product selection. Whether a building is located in a mild climate or an area with heavy winter weather, managing how snow releases from the roof is an important part of protecting the structure and the surrounding property.

About Pacific Building Systems

Pacific Building Systems is a fourth-generation, family-owned steel building manufacturer located in Woodburn, Oregon. The company began in 1962 as a small operation serving local farms and community projects. Over time, it has grown into a well-established provider of custom pre-engineered metal buildings, delivering more than ten thousand structures throughout the Pacific Northwest and other regions. PBS offers comprehensive in-house services, including design, engineering, manufacturing, and shipping, enabling it to support commercial, industrial, agricultural, aviation, and government applications. The company emphasizes strong customer relationships, dependable service, and durable steel building solutions designed for long-term performance.

PBR Panel

The PBR panel offered by Pacific Building Systems is a structural exposed-fastener panel designed for both roofing and wall applications where strength and spanning capability are essential. It provides 36 inches of coverage, with ribs spaced 12 inches apart and 1.25 inches high, giving the panel the rigidity needed for demanding conditions. It is most commonly produced in 26 gauge, although heavier gauges may be available for certain projects. The purlin-bearing leg improves load transfer at sidelaps, and the deeper rib profile supports longer spans over open framing while helping manage snow. These features make the PBR panel a dependable option for agricultural, industrial, and commercial buildings that require durability and weather resistance.

This panel works with a wide selection of our snow retention products, allowing installers to match the system to the project and climate. Stainless steel pad-style guards from the SnowCatcher series, including Standard, Sun Burst, Maple Leaf, Fleur-de-lis, Kodiak, and Mustang designs, can be mechanically fastened to the panel. Installers can mount polycarbonate models such as the SnoBlox Deuce, IceJax II, and SnoBlox Ace using adhesive or screws. Still, they must mechanically fasten the Snojax I due to incompatibility with the adhesive. For snow breakup, the SnowBreaker and SnowBreaker 3M offer effective performance. In regions with snow loads above 45 PSF, or when a cleaner appearance is preferred, rail systems like SnoBar and ColorBar provide a strong, streamlined solution. These systems use Tall ColorBrackets with butyl tape gaskets for secure attachment. Because the panel has a textured finish, installers may need to apply a thicker layer of adhesive or sealant to achieve proper bonding.

Tuf Rib Panel

The Tuf Rib panel from Pacific Building Systems is a versatile exposed-fastener option commonly used in residential, agricultural, and light commercial projects where affordability and simple installation are priorities. It provides 36 inches of coverage and is typically manufactured in 29-gauge, making it a more economical choice than heavier structural panels like PBR. The profile usually includes ribs spaced 9 inches on center with a rib height of about three-quarters of an inch, creating a traditional, closely spaced appearance. Because it is lighter and has a lower rib height, Tuf Rib performs best when installed over solid decking or framing with minimal spacing rather than long spans. This fact makes it a practical solution for projects that value cost efficiency, appearance, and ease of installation. See the Snow Guards Compatibility Chart for Pacific Building Systems Tuf Rib Screw Down Metal Roofing Panels.

This panel supports many of our snow retention products, giving installers flexibility across different roof types. Polycarbonate guards such as the SnoBlox Deuce, Ecojax, and SnowBreaker fit neatly between the minor ribs. Metal options like the SnoCleat PBR and all six SnowCatcher designs attach to the flat center area with screws. Other models, including the Snojax I and Icejax I, span the minor ribs. The Icejax I can be installed with adhesive or screws, while the Snojax I requires mechanical fastening. The panel is also compatible with Tall ColorBrackets, which pair with aluminum ColorBar PBR or galvanized SnoBar PBR rail systems. With this wide range of compatible products, the Tuf Rib panel offers reliable snow management options for many climates.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Pacific Building Systems

How Can I Coordinate My Snow Guards with My Roof?

Selecting finishes that closely match your roof’s color and surface texture helps the guards blend naturally into the design. Durable powder-coated options offer long-lasting color, while field-applied coatings provide an economical way to fine-tune the appearance.

Should I Use Sealant Under My Screw-Mounted Snow Guards?

Using sealant beneath screw-down guards helps close small gaps, limit water intrusion, and keep moisture from seeping into the roof assembly. This extra barrier supports better long-term reliability.

What Snow Guard Solutions Work Best for Unique Roof Shapes?

Roofs featuring curves, arches, or other irregular contours often need guards shaped or chosen to match those profiles. Standard units may not sit correctly, so custom-fit selections and careful adherence to manufacturer guidance are key to dependable performance.

When Is the Best Time to Install Adhesive-Mounted Snow Guards?

Adhesive-set guards bond most effectively in warm conditions, typically late spring through early summer when temperatures remain above 50°F. Heat accelerates curing, and adhesives such as SureBond SB-190 generally reach moisture resistance within roughly a day.

Should I Test Fit Snow Guards Before Final Installation?

Temporarily placing the guards on the roof allows you to verify spacing, alignment, and the overall layout before permanently fastening them. This preview step helps ensure a consistent pattern and a clean finished appearance.

Compatibility Guidance Note

The compatibility information presented in this guide is based on SnoBlox-Snojax product testing and field experience with Pacific Building Systems metal roof panel profiles. Panel manufacturers periodically update profile specifications, and individual project variables including seam condition, coating type, and installation method can affect outcomes. Customers are encouraged to confirm current panel specifications directly with Pacific Building Systems and to contact SnoBlox-Snojax with project-specific questions before ordering.
