Snow Guard Solutions for Rigidply Rafters’ Exposed-Fastener Roof Panels

What snow retention options work best with Rigidply Rafters’ exposed-fastener metal roofing systems?

Exposed-fastener metal roofs are particularly prone to sudden snow and ice slides during winter months, commonly known as rooftop avalanches.

The slick surface of these panels allows snow and ice to accumulate and then release abruptly, creating hazards for people, pets, and property below. To mitigate these risks, we offer customized snow retention systems tailored to suit a range of roof profiles and regional climates. Our lineup includes both individual snow guards and rail-style systems that fit a variety of panel types and roof slopes. We also provide helpful tools like installation manuals, blog content, and updated compatibility charts for top roofing brands. In regions with heavy or frequent snowfall, these systems are essential for controlling the timing and flow of snow and ice shedding from the roof.

About Rigidply and Their Exposed-Fastener Roofing

Since its founding in 1954, Rigidply Rafters has been a trusted name in engineered wood truss production, blending technical innovation with strong faith-based principles. Headquartered in Pennsylvania, this family-owned company has become a leading supplier of roof and floor trusses throughout the Northeastern United States. Their pioneering work with metal-plated wood trusses began in 1963. Despite enduring major challenges, including two catastrophic fires, they've remained steadfast in their mission. Today, the founders' children and sons-in-law continue to lead the company, upholding its legacy of craftsmanship, customer care, and spiritual conviction.

Grandrib 3 Plus

The Grandrib 3 Plus panel is a widely used solution for metal roofing and siding, known for its durability and timeless appearance. It spans 36 inches in width and features ¾-inch ribs spaced 9 inches apart. Typically manufactured in 29-gauge steel, these panels offer excellent strength and corrosion resistance. A heavy zinc coating provides long-term protection, while the Enduracote paint system enhances weather resilience and visual appeal. With UL 2218 Class 4 hail impact and UL 790 Class A fire ratings, the panels meet high safety standards. Their anti-siphon side-lap design improves moisture resistance, and custom lengths up to 40 feet make them suitable for residential, agricultural, and commercial projects.

The Grandrib 3 Plus panel supports a variety of snow retention solutions tailored to different materials and installation preferences. For polycarbonate options, the SnoBlox Deuce and SnowBreaker models are ideal for placement between the minor ribs. Metal snow guards, such as the SnoCleat PBR and six decorative SnowCatcher styles, are best installed in the flat center section of the panel. Additional choices include the Snojax I, which requires screw mounting, and the Icejax I, which can be installed with adhesive or screws by contractors. For rail systems, pair the panel with Tall ColorBrackets and compatible fasteners to support aluminum ColorBar PBR or galvanized SnoBar PBR. This combination offers a robust and reliable solution for managing snow loads across diverse climates.

Strongrib Aluminum

Strongrib Aluminum panels offer a lightweight, corrosion-resistant option for roofing and siding, especially in agricultural settings. Produced by Fabral and distributed by Rigidply Rafters, these panels withstand exposure to animal waste and harsh environmental conditions without rusting at the edges. Made from 90% recycled materials and fully recyclable, they support eco-conscious construction. With minimal upkeep and a 30-year corrosion warranty, they deliver lasting value. The panels feature ¾-inch ribs, 36-inch coverage, and a 9-inch pitch, available in plain or white finishes. Their resilience and non-corrosive properties make them ideal for livestock enclosures and other demanding farm applications.

Strongrib Aluminum panels are compatible with a broad selection of snow retention products. Screw-mounted rail systems, such as SnoBar and ColorBar, work well, along with the SnoCleat PBR and stainless steel SnowCatchers in styles like Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, Kodiak, and Standard. Contractors can install most polycarbonate guards using adhesive or screws, though installers must mechanically fasten the Snojax I. For adhesive-mounted guards, we recommend Surebond SB-190. Note that this adhesive is not suitable for metal pad-style guards. Unlike standard PBR panels, the Super Panel design includes a single minor rib between major ribs. Installers should offset smaller guards to one side for consistent alignment. At the same time, contractors must center models like Icejax II over the minor rib. The Snojax II is too wide and not compatible. Always mount guards on the flat sections and anchor them into a solid substrate for dependable performance.

Mighti-Rib

Mighti-Rib panels are a versatile exposed-fastener option for both roofing and wall applications, offering a blend of classic aesthetics and modern durability. Each panel provides 36 inches of net coverage and features ribs that are 1-1/4 inches tall, spaced 12 inches apart. Custom lengths, ranging from 6 to 45 feet, accommodate a wide range of project requirements. Made from 26-gauge steel, with heavier gauges available upon request, these panels endure tough conditions. They come in multiple color options, and you can install them vertically or horizontally. Safety certifications include UL 790 Class A for fire resistance and UL 2218 Class 4 for impact resistance, making them suitable for both residential and commercial use.

Mighti-Rib panels offer flexible snow guard installation options to meet a variety of needs. Compatible models include screw-mounted systems like SnoBar, ColorBar, SnoCleat PBR, and stainless steel SnowCatchers in decorative styles such as Standard, Fleur-de-lis, Sun Burst, Maple Leaf, Mustang, and Kodiak. Contractors can attach most polycarbonate guards with screws or adhesive, except for the Snojax I, which requires mechanical fastening. For adhesive applications, we recommend Surebond SB-190; however, it is not suitable for use with metal pad-style guards. You should center smaller guards between the minor ribs for the best results. Models, such as Snojax II and Icejax II, should be positioned to either side of the minor rib and aligned consistently. Never install guards or rails on the high ribs; instead, secure them through the flat sections into a solid substrate to ensure long-term stability.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Rigidply

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

Installers achieve the best results with adhesive snow guards when they apply them in warm weather, typically from late spring to early summer when temperatures exceed 50°F. Heat speeds up the curing process, while colder temperatures may hinder proper bonding. Fast-setting adhesives, such as SureBond SB-190, typically resist moisture within 24 hours, minimizing weather-related setbacks.

Should I Apply Sealant Under Screw-Mounted Snow Guards?

Applying a generous layer of sealant beneath screw-attached polycarbonate snow guards helps seal gaps, reduce water intrusion, and prevent leaks. This additional protection reinforces the installation and contributes to long-term performance.

How Can I Coordinate Snow Guard Finishes with My Roof Design?

Select finishes that harmonize with your roof's color palette and architectural style. Powder-coated finishes or decorative inserts can elevate curb appeal and help the guards blend into the roofline. Professional coatings offer lasting durability, but DIY options may deliver quicker results at a lower cost.

How Can I Fasten Snow Guards for Maximum Strength?

To ensure maximum holding power, attach snow guards to structural elements, such as rafters or purlins, rather than just the roof panels. Reinforcing the mounting area can improve load capacity and long-term stability.

Should I Test Fit Snow Guards Before Final Installation?

Pre-fitting snow guards allows you to confirm proper spacing and alignment before final attachment. This step helps fine-tune placement and ensures a clean, professional-looking result.

What Snow Guard Solutions Work Best for Unique Roof Shapes?

Roofs with unconventional shapes, such as those with curved or arched profiles, often require custom snow guard solutions. Standard models may not fit correctly, so it is advisable to choose guards designed for your roof's specific contours and consult the manufacturer for guidance on the best fit.

How Does Roofing Material Affect Snow Guard Placement?

The type of roofing plays a key role in determining snow guard spacing and layout. Softer metals, such as copper or aluminum, may require tighter spacing and multiple rows, whereas harder materials, like steel, can support wider gaps. Always verify that adhesives and sealants are compatible with your roofing material to prevent bonding issues.
