What Are the Best Snow Guards for Metal Roofs?

Buildings with standing seam metal roofs face significant challenges during winter due to the risk of unexpected snow and ice slides. These sudden avalanches can threaten people, pets, vehicles, and nearby structures. The smooth surface of metal roofs exacerbates this issue by releasing accumulated winter precipitation without warning, creating a notable safety concern. Implementing effective snow and ice retention strategies that safeguard the surrounding area is essential to address this problem. Snow retention devices, such as snow guards and rail systems, offer practical solutions by preventing snow from sliding off the roof. These devices can suit various roof styles and configurations. Factors like roof pitch, panel design, and local climate conditions require careful consideration when choosing these protective measures. Property owners can utilize online resources, including articles and blog posts, to identify the most appropriate snow retention solutions. By adopting these strategies and leveraging available resources, building owners can significantly reduce the risks associated with snow and ice accumulation on standing seam metal roofs. This proactive approach helps ensure a safer environment during the winter months, protecting both people and property near these structures.

CRS 25/CRS 38

The CRS series is widely recognized for its stylish design and outstanding performance, making it a popular choice. These panels are well-suited for contemporary architectural projects, offering exceptional weather resistance and straightforward installation. The CRS 25 panel features a 1-inch seam height and a width of 17 inches, while the CRS 38 panel has a taller 1.5-inch seam and a standard width of 16 inches. Installation involves securing the panels with concealed fastener clips and mechanically seaming them to a 90-degree or 180-degree profile.

This panel is compatible with various snow retention solutions, especially adhesive-mounted polycarbonate components. Proper adhesive application prevents moisture-related issues between the snow guards and roof panels. Customers can choose from an extensive range of options, including larger units like IceJax II, Snojax II, and SnoBlox Ace, as well as smaller alternatives such as the Deuce and IceJax I. For enhanced safety during controlled snow and ice release, we recommend the SnowBreaker and SnowBreaker 3M. The panel's unique rib design supports clamp-on snow guards, including rail systems such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar. It is advisable to test-fit a sample clamp before placing an order to ensure compatibility with specific panel designs. Installers commonly use standard stainless steel SnoBar clamps or aluminum RoofClamp options. Still, this preliminary step helps confirm proper fit and functionality.

CRB Panels

CRB panels are designed for exceptional durability, making them ideal for commercial and residential applications. They deliver reliable, long-lasting protection against various weather conditions. With a seam height of 1.75 inches and a panel width of 17 inches, they feature a distinctive batten seam cover that creates a bold and substantial appearance.

CRB panels pose challenges when selecting compatible snow guard solutions due to their wide, separate batten strip design, which limits the available options. Clamp-on individual snow guards, such as the SnoCleat RC and RCT, are unsuitable for this panel type. Clamp-on snow rails like ColorBar or SnoBar have the same problem. Consequently, glue-down polycarbonate pad-style snow guards are the only viable choice for this roofing system. Among the snow guard products compatible with the PC System Batten Seam are larger options like the IceJax II, Snojax II, and SnoBlox Ace, as well as smaller guards like the Deuce and IceJax I. Also, safer alternatives designed to shed snow and ice, such as the SnowBreaker and SnowBreaker 3M, may be considered. It may be necessary to apply a more generous amount of adhesive to accommodate the panel's striations and any optional texture To ensure proper sealing and prevent moisture intrusion beneath the snow guard.

CRC Panels

CRC panels stand out for their distinctive design and exceptional strength, making them ideal for projects that demand visual appeal and reliable structural performance. See the Snow Guards Compatibility Chart for CR Systems CRC Standing Seam Metal Roofing Panels. These panels feature a batten cover seam in heights of either 1 inch or 1.5 inches, with panel widths measuring 15 inches.

This roofing panel incorporates a batten cap or batten strip for the rib, which makes certain snow retention systems incompatible. Clamp-on individual snow guards, such as the SnoCleat RC and SnoCleat RCT, and clamp-on snow rail systems, like the SnoBar and ColorBar, cannot be used effectively with this design. Installers use Batten strips for aesthetic reasons; however, clamp-on solutions are unsuitable because the clamps would only grip the strip itself rather than the main panels. This lack of proper torque can cause the strips to detach from the roof, potentially leading to costly damage and repairs. Instead, this panel is compatible with glue-down polycarbonate snow guard models like SnoBlox Deuce, SnoBlox Ace, IceJax II, and Snojax II. For a safer and more controlled approach to managing snow and ice shedding, the SnowBreaker system is an effective option. It breaks snow and ice into smaller chunks, slowing their release from the roof. The recommended adhesive for this installation method is Surebond SB-190. This glue is the industry standard for glue-down snow retention systems.

Considerations for Adding Snow Guards to Standing Seam Roofs by CR Systems

Adapting Snow Retention to Roofing Materials

Tailor your snow retention strategy to suit the specific properties of roofing materials. Softer metals, such as aluminum or copper, may necessitate closer spacing and additional rows of clamp-on guards or rails compared to more robust materials like steel.

Protecting Copper Roofs

Exercise caution when installing snow guards on copper roofs to avoid chemical reactions. For adhesive-mounted pad-style guards, ensure no direct contact with copper and the adhesive itself. This contact could cause premature corrosion and damage to the panel. Apply protective coatings to bar systems before attaching them to copper surfaces to prevent dissimilar metal interactions.

Holistic Roof Protection Plans

Design a comprehensive plan to safeguard the entire roof structure. Distribute multiple rows of retention devices evenly to manage stress and weight effectively. Use our spacing guidelines and calculation tools for optimal placement and maximum protection.

Managing Curved Roofs Effectively

Curved roofs present unique challenges for traditional flat pad-style guards. Roofing professionals must innovate to address these architectural challenges successfully.

Assessing Local Snow Load Conditions

When selecting a retention system, evaluate your region's typical snow accumulation, known as the Ground Snow Load. While pad-style guards may suffice in areas with moderate snowfall (up to 45 psf), regions with heavier snow loads demand specialized rail systems to prevent snow slides.

Strategic Adhesive Application

Plan adhesive-mounted installations during suitable temperature ranges. When determining curing times, account for ambient temperature fluctuations; for instance, high-quality adhesives like Surebond SB190 require about 28 days at 50°F or higher for full curing.

Ensuring Compatibility of System Components

Before installation, verify that all components are compatible with the specific roof type. Testing individual elements can help avoid errors and ensure seamless integration. Components are often available individually or in sample kits for evaluation.

Integrating Ice Control Solutions

Incorporate specialized elements like our IceStopper accessories into snow rail retention systems for areas prone to ice accumulation. Position these components carefully, especially on roofs with higher seams, to mitigate ice-related issues effectively.

Enhancing Roof Aesthetics Through Snow Management

Choose snow retention systems that complement your roof's design and color scheme. Options include color-matched powder-coated systems or guards with coordinating metal inserts. Budget-conscious homeowners can explore local finishing services or DIY coloring methods.

Exploring Advanced Attachment Techniques

Investigate modern fastening methods for standing seam metal roofs that maintain structural integrity while preserving weatherproofing. Options include clamp-on or adhesive-mounted systems that comply with warranty requirements.
