Snow Guards For Metl-Span Exposed Fastener Metal Roof Panels

See the Snow Guards Compatibility Chart for Metal Central Screw Down Metal Roofing Panels.

Which snow guards work best for Metl-Span exposed fastener metal roof panels?

Metal roofs with exposed fasteners are often prone to sudden snow and ice slides during the winter season.

The smooth surface of metal roofing allows snow and ice to slide off quickly, creating hazards for people, pets, and property below. To mitigate these risks, we offer a range of snow retention products specifically designed for various roofing types and materials. These options include snow guards and rail systems that accommodate a variety of roof slopes, panel designs, and weather conditions. Customers also have access to our resources, including detailed blog articles, clear installation instructions, and regularly updated lists of roof manufacturer compatibility. In regions with frequent and heavy snowfall, these products are crucial for mitigating the risks associated with snow and ice accumulation, thereby protecting both individuals and property throughout the winter months.

Exposed Fastener Metal Roof Panels by Metl-Span

Since its establishment in 1968, Metl-Span has been a recognized leader in the insulated metal panel industry. Over the past five decades, the company has earned a solid reputation through ongoing advancements in the development, production, and marketing of high-performance insulated metal panels and related construction materials. In 2021, the company underwent a significant change when it became part of Metl-Span Corporation following the acquisition of the insulated panel division from Cornerstone Building Brands, which included both Metl-Span and Centria. This development led to the creation of the Insulated Panel Group. It expanded the product range with the introduction of TrueCore. Metl-Span is now a top manufacturer in North America, specializing in insulated metal panels used in commercial and industrial settings. With a strong emphasis on quality and innovation, the company has established itself as a trusted source for building envelope solutions. Operating from eight plants across the U.S. and Canada, Metl-Span remains committed to delivering efficient service. Its wide array of products, including the well-known CFR Insulated Metal Panels, is valued for superior insulation and energy efficiency, making them a popular choice for many construction projects.

The LS-36 Insulated Roof and Wall Panel

The LS-36 Insulated Roof and Wall Panel is a multi-purpose panel with exposed fasteners, suitable for both roof and wall installations. It offers effective insulation and a range of design options, making it adaptable for many types of buildings. With a 36-inch coverage width and 12-inch rib spacing, the panel is available in thicknesses ranging from 1½ inches to 6 inches. It can be custom-cut to lengths of up to 50 feet. Installation is made easy through a through-fastening system and a tongue-and-groove joint that ensures secure overlapping of panels. The core is foamed-in-place polyurethane that does not contain ozone-depleting substances, providing thermal efficiency tailored to specific project needs. Its outer surface is Galvalume® steel, with optional galvanized finishes. It comes in a smooth or embossed texture. Inside, the panel includes a white-coated, stucco-embossed finish and is available in several gauges, including 22, 24, and 26. Suitable for roof slopes of at least ½ inch per foot, this panel works well for both new builds and retrofits, particularly in pre-engineered metal building systems. The system has undergone standard performance testing for weather durability and water resistance, demonstrating its reliability in different conditions. However, it is not designed for use in refrigerated or freezer environments unless specifically manufactured for those purposes. Ensuring proper handling and installation is key to maintaining the panel's performance and warranty. See the Snow Guards Compatibility Chart for Metal Central LS-36 Screw Down Metal Roofing Panels.

Because this panel is insulated, it is only compatible with snow guards that use adhesive mounting. Popular choices include the SnoBlox Deuce, IceJax II, and Ace. Most polycarbonate models are compatible with this panel, except for the Snojax I, which requires a screw-down installation method. When installing polycarbonate snow guards with adhesive, it is crucial to use Surebond SB-190, the recommended adhesive for this application, and to avoid applying it to metal pad-style snow guards. For optimal performance, contractors should install smaller snow guards between the minor ribs at the center of the panel. Models like the Snojax II and IceJax II require off-center placement, straddling the minor rib or mesa on either side. Snow guards should never be mounted directly on the high ribs; instead, they must be positioned on the flat, lower areas to ensure proper and secure installation.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Metl-Span

Attach Guards to Structural Supports

To ensure maximum stability, fasten snow guards directly to the roof's structural framework, such as rafters or metal purlins, rather than attaching them only to roofing panels. If the roof structure is insufficient, reinforce it or use specially formulated adhesives to enhance strength.

Choose Guards for Unique Roof Shapes

Pad-style snow guards are typically ineffective on roofs with curved, arched, or unusual shapes. In such instances, select snow retention devices that are designed specifically for non-standard roof profiles. Consult the roof panel manufacturer for recommendations tailored to your specific roof design.

Check Placement Before Final Installation

Start by temporarily placing one or more snow guards on the roof to verify their fit and positioning. Performing this test fit helps identify any installation challenges before committing to permanent installation.

Apply Sealant to Prevent Leaks

When installing snow guards made of polycarbonate and affixed with screws, apply sealant over the entire base of each guard. This technique seals gaps properly, improves waterproofing, and reduces the risk of leaks.

Install Adhesive Guards in Warm Weather

For snow guards installed with adhesive, schedule the installation for late spring or early summer, when daytime temperatures consistently remain above 50°F for several weeks. Warm conditions are essential for the adhesive to cure effectively; cooler weather slows down the curing process. SureBond SB190 achieves water resistance approximately 24 hours after application, making rain unlikely to compromise the bond after that.

Coordinate Finishes with Roof Appearance

Select snow guards with finishes or coatings that complement your roof's color and style. Options include powder coating and custom color inserts to achieve a visually appealing and unified look. While professionally applied finishes tend to last longer, home-applied options might be more affordable and faster.

Adjust for Roofing Material

Adjust the spacing and layout of snow guards according to the roofing material. Softer metals, such as copper or aluminum, often require closer spacing and additional rows compared to harder metals, like steel. Always confirm that coatings and finishes are compatible to avoid negative chemical reactions between metals.
