Standing Seam Metal Roof Panels by Varco Pruden

Since its formation, Varco Pruden Buildings has established itself as a prominent name in the pre-engineered steel building industry. Its origins go back to R.G. Varner Steel Products and Pruden Products. R.G. Varner Steel Products, founded in 1948 in Pine Bluff, Arkansas, specializes in manufacturing equipment for farm buildings. Similarly, Pruden Products, created in 1950 by Clark Prudhon in Fort Atkinson, Wisconsin, initially focused on farm-building equipment before shifting to steel-building components. In 1968, these two companies merged to form Varco Pruden Buildings, leveraging their expertise to deliver innovative pre-engineered steel building systems. Over the years, the company expanded its product offerings, manufacturing capabilities, and network of authorized builders throughout North America. In the early 2000s, it became part of BlueScope Steel, an Australian global steel manufacturer, through its acquisition by BlueScope's North American subsidiary. Today, Varco Pruden remains a leader in the industry, supported by nearly 1,000 authorized VP Builders serving markets across the United States and Canada.

SLR II™ ROOF

The SLR II™ Roof from Varco Pruden is a concealed-fastener standing seam metal roof system designed for low-slope applications, blending architectural appeal with structural performance, as detailed by Varco Pruden, a recognized leader in pre-engineered metal building systems. Crafted from 22 or 24-gauge Galvalume steel, it features 16-inch wide, 2-inch deep panels with factory-installed sealant and pre-caulked galvanized clips, enabling field-seaming to form a weathertight single membrane suitable for slopes as low as 1/4 inch per 12 inches and panel lengths up to 40 feet. Varco Pruden emphasizes its durability, with certifications like the UL 90 Wind Uplift Rating and approvals from the U.S. Army Corps of Engineers and Factory Mutual for wind resistance. At the same time, its thermal-responsive design uses a galvanized clip (22-gauge hook, 16-gauge base) to accommodate temperature-induced movement. Installation is efficient due to factory-punched and notched panels, ensuring precision and modularity. It's paired with tailored accessories like the CFR™ Roof Curb and DuraCurb™ to maintain integrity around penetrations. This fact makes the SLR II™ an economical, low-maintenance solution for commercial and industrial buildings where aesthetics and reliability are key.

This panel's adaptability is showcased through its broad compatibility with our various snow retention solutions, particularly those using adhesive-mounted polycarbonate components. Proper adhesive application prevents moisture-related problems between our snow guards and roof panels. Customers have a wide array of options, including larger units such as IceJax II, Snojax II, and SnoBlox Ace, as well as more compact alternatives like the Deuce and IceJax I. For improved safety during controlled snow and ice release, we recommend the SnowBreaker and SnowBreaker 3M. The panel's distinctive rib design allows for clamp-on snow guards, including rail systems like SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. We recommend test-fitting a sample clamp before finalizing your order to ensure proper fit and functionality with your specific panel design. While installers typically use standard stainless steel SnoBar clamps or aluminum RoofClamp alternatives, this step helps guarantee compatibility.

SSR™ STANDING SEAM ROOF

The SSR™ Standing Seam Roof, a product of Varco Pruden, is an advanced roofing solution that combines durability with energy efficiency. This system features panels that are 24 inches wide with distinctive 3-inch high trapezoidal ribs, creating a robust profile. These panels interlock seamlessly, forming a continuous weathertight surface across the roof. The system's unique design includes specially engineered clips that allow for significant thermal movement, up to 1-5/8 inches in either direction, which is crucial for maintaining the roof's integrity in varying temperatures. Available in both 24-gauge and 22-gauge steel, the SSR panels can be finished with acrylic-coated Galvalume® or KXL cool colors, offering protection and aesthetic appeal. The system's versatility is evident in its compatibility with various insulation methods, potentially achieving insulation values up to R-38. This versatility makes it an excellent choice for energy-conscious building designs. The SSR roof is not just about performance; it also prioritizes safety. It can be equipped with several fall protection systems, ensuring worker safety during installation and maintenance without compromising the roof's integrity. The SSR system's performance is backed by industry-standard certifications, including UL 90 and FM Class 1 ratings, testifying its ability to withstand severe weather conditions. Its patented ridge system further enhances its weathertight properties. Whether for new construction or retrofitting existing structures, the SSR Standing Seam Roof system offers a long-lasting, low-maintenance solution that meets modern commercial and industrial roofing needs.

The flexibility of this panel comes from its ability to work with a wide range of our snow retention solutions, especially those that use adhesive-mounted polycarbonate components. It's essential to apply adhesive correctly to avoid issues related to moisture between snow guards and roof panels. Customers can select from various options, ranging from larger units like IceJax II, Snojax II, and SnoBlox Ace to more compact choices like Deuce and IceJax I. For better safety during controlled snow and ice release, we recommend using the SnowBreaker and SnowBreaker 3M. The panel's unique rib design is compatible with clamp-on snow guards, including rail systems such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. Although installation typically involves standard stainless steel SnoBar clamps or aluminum RoofClamp alternatives, testing a clamp sample before placing an order is recommended to ensure proper fit and functionality with the specific panel design.

Considerations for Adding Snow Guards to Standing Seam Roofs by Varco Pruden

Analyze Snow Load Requirements

Assess your area's ground snow load to guide your snow retention system selection. Individual pad-style guards are typically sufficient for regions with snow loads up to 45 psf. Heavier snowfall areas require more substantial rail systems. Seek expert advice from panel manufacturers for roofs unsuitable for snow rails or in areas with ground snow loads exceeding 45 psf.

Design a Comprehensive Layout

Create a holistic snow retention plan covering the entire roof area, usually incorporating multiple ascending rows for even load distribution. Arrange individual pad-style snow guards in a zigzag staggered pattern and snow rails in straight lines. Avoid isolated installations above exits, walkways, or architectural elements to prevent system overload. Utilize our available resources, spacing guides, and custom quote forms to optimize your design.

Verify Component Compatibility

Before full implementation, ensure compatibility of chosen snow retention components. We suggest testing samples of our snow guards, clamps, brackets, or fittings on your roof type. This precautionary step helps avoid costly mistakes and ensures optimal system integration.

Manage Ice Formation

For standing seam roofs with rail systems, consider adding IceStopper ice management attachments, especially above high-traffic pedestrian areas. These can be installed initially or added later. Proper spacing is crucial to prevent ice from sliding under the bar, mainly for seams taller than 1 inch.

Follow Proper Installation Protocols

Avoid directly attaching snow guards or rails to standing seam metal roofs using penetrating fasteners. This incorrect method often leads to panel damage, compromised weatherproofing, and expensive repairs due to natural thermal expansion and contraction. Instead, clamp-on or adhesive-mounted systems ensure compatibility and maintain warranty validity.

Time Installation Optimally

Plan installation during late spring or early summer for adhesive-mounted polycarbonate snow guards. Our recommended adhesive, Surebond SB-190, needs about 28 days at 50°F (10°C) to fully cure, with rain resistance developing after approximately 24 hours.

Integrate Aesthetically Pleasing Finishes

Match snow retention system colors to enhance your roof's visual appeal. Some products offer optional, adaptable metal inserts that match your roof color or create contrasts. These can be purchased with snow guards or made on-site using extra roofing material. For precise color matching, consider optional full-coverage powder coating services. You can explore DIY painting or local powder coating options for greater color control or faster processing.
