Which snow guard systems work best with Garland Co. standing seam panels?
Homeowners and building owners admire Standing seam roofing for its sleek design and long service life. However, in areas prone to heavy snowfall, these roofs can present safety risks.
When large sheets of snow or ice suddenly slide off, often called a roof avalanche, they can cause property damage or pose a danger to people and pets below. To reduce these risks, contractors must select snow guards or bar-style retention systems engineered for the roof's profile and fastening method. Concealed-fastener panels, in particular, demand specialized solutions that ensure secure installation and consistent performance. This blog explores snow guard compatibility by panel type, focusing on Garland Co.'s offerings to help builders and property owners make informed, safety-driven decisions.

R-Mer Shield
The R-Mer Shield panel features a 2-1/16-inch vertical seam that delivers exceptional wind uplift resistance. It is available in widths of 12.75, 16.75, and 18.75 inches, offering flexibility in rib spacing. Material options include galvanized steel (20, 22, and 24 gauge), aluminum (.040 and .050 inches), zinc (.7mm, .8mm, and 1.0mm), stainless steel (20, 22, and 24 gauge), and copper (16 oz. and 20 oz.). The panel meets rigorous standards, including FM Class I-210, ASTM E 1592, ASTM E 1680, and ASTM E 1646. Architects and engineers often specify R-Mer Shield for government facilities, military bases, and other mission-critical projects because of its strength and resilience. See the Snow Guards Compatibility Chart for Garland Co R-Mer Shield Standing Seam Metal Roofing Panels.
This panel supports a wide range of our snow retention systems, with adhesive-mounted polycarbonate guards being particularly effective. Proper adhesive application is essential to prevent moisture entrapment and ensure durability. Heavy-duty options like IceJax II, Snojax II, and SnoBlox Ace provide robust protection. At the same time, smaller models such as IceJax I, Ecojax, and SnoBlox Deuce are ideal for tighter spaces. For added defense against sliding snow, SnowBreaker and SnowBreaker 3M are reliable solutions. This panel’s rib profile also accommodates clamp-on systems such as SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar when secured with aluminum RoofClamp attachments. The standard stainless steel SnoBar clamp may not fit this panel's ribs. We recommend a test installation to confirm compatibility.
R-Mer Span
The R-Mer Span panel features a 2-3/8-inch-high vertical seam. It incorporates mesas throughout its profile to minimize oil canning. Available in widths of 12, 16, and 18 inches, it offers multiple rib spacing options. Material choices include galvanized steel (20, 22, and 24 gauge), aluminum (.032, .040, and .050 inches), copper, stainless steel, and zinc. Certifications include FM Class 1-195, UL 90, Class A fire rating, UL 263 fire assembly testing, ASTM E 1592, ASTM E 283, ASTM E 1680, ASTM E 331, and ASTM E 1646. With its wide-span capabilities and structural strength, R-Mer Span is a preferred solution for large-scale commercial and industrial projects, including warehouses, factories, and retail centers.

This panel supports a variety of our snow retention systems, particularly adhesive-mounted polycarbonate guards. Correct adhesive use is critical to avoid trapped moisture and ensure long-term performance. Heavy-duty models like IceJax II, Snojax II, and SnoBlox Ace provide strong protection. At the same time, compact designs such as IceJax I, Ecojax, and SnoBlox Deuce are effective in smaller applications. SnowBreaker and SnowBreaker 3M add extra safety against sliding snow. Clamp-on systems, including SnoCleat RCT, SnoBar, and ColorBar, can also be used, but only with aluminum RoofClamp RCT attachments. The RC Clamp and standard SnoBar clamp are not compatible, so we advise a trial installation to verify fit.
R-Mer Loc
The R-Mer Loc panel features a 1-3/4-inch vertical seam with an integral standing seam design that ensures watertight performance. It is available in widths of 12, 16, and 18 inches, offering flexibility in rib spacing. Material options include galvanized steel (22- and 24-gauge) and .040-inch aluminum. Certifications include UL 90, Class A fire rating, ASTM E 1592, ASTM E 283, ASTM E 1680, ASTM E 331, and ASTM E 1646. Government facilities, military bases, and other mission-critical projects often rely on R-Mer Shield for its strength and resilience. See the Snow Guards Compatibility Chart for Garland Co R-Mer Loc Standing Seam Metal Roofing Panels.
This panel works well with our adhesive-mounted polycarbonate snow guards, provided adhesives are applied correctly to prevent moisture issues. Larger systems such as IceJax II, Snojax II, and SnoBlox Ace deliver strong protection. At the same time, smaller options like IceJax I, Ecojax, and SnoBlox Deuce are effective in compact areas. SnowBreaker and SnowBreaker 3M add further control for sliding snow. The panel's ribbed design enables installers to secure clamp-on assemblies like SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar with stainless steel SnoBar clamps or aluminum RoofClamp attachments. As with other panels, we recommend a preliminary clamp installation to ensure proper fit and performance.

Considerations for Adding Snow Guards to Standing Seam Roofs by Garland Co
Apply adhesives during the right weather window.
Contractors should only install Snow guards that depend on adhesives when temperatures are above 50°F. While water resistance develops within the first 24 hours, complete curing takes about 28 days. Avoid using Surebond SB-190 on copper surfaces, as it can cause premature corrosion.
Use systems tailored for unique roof shapes.
Roofs with steep slopes, curves, or unconventional designs often need specialized snow retention solutions. Consult with your roofing supplier to determine the most effective system for your particular layout.
Order sample snow guards for test-fitting.
Samples can be purchased without a minimum order, allowing you to test them directly on your roof. This practice ensures proper fit and helps prevent installation errors. Always follow the manufacturer's approved methods to maintain warranty coverage.
Adapt installation for complex roof features.
Contractors may need to adjust snow guard placement around valleys, slope transitions, or other architectural details. Correct positioning in these areas is essential to maintain system performance and reduce the risk of failure.
Verify that guards match your roof design.
Contractors should select snow guards specifically designed for your roof type and profile. Compatibility charts are available to help avoid mismatches and ensure a secure, long-lasting installation.
Account for local snow load standards.
Check regional building codes to confirm the required snow load capacity before choosing a system. Pad-style guards typically support up to 45 pounds per square foot, while heavier snow conditions call for rail-style systems.
