This roofing panel supports various snow retention options, particularly those that work with adhesive-mounted polycarbonate snow guards. Proper application of adhesive is essential to keep the snow guards securely attached and to avoid problems caused by moisture or refreezing. Since the panel surface is stamped rather than smooth, it often requires a thicker layer of adhesive to ensure a secure bond. There are many snow guard models available, including larger options such as IceJax II, Snojax II, and SnoBlox Ace, as well as smaller choices like the SnoBlox Deuce and IceJax I. For added protection against sliding snow and ice, we recommend the SnowBreaker and SnowBreaker 3M. The panel's ribbed design accommodates both adhesive-mounted and clamp-on snow retention systems. Clamp-on options include SnoCleat RC, SnoCleat RCT, SnoBar, and ColorBar, which attach using stainless steel SnoBar clamps or aluminum RoofClamp fasteners. We recommend testing a clamp on the panel before making a final choice to ensure compatibility with specific panel types.

Considerations for Adding Snow Guards to Standing Seam Roofs by Watson Metals

Verify local snow load requirements.

Consult your local building codes to determine ground snow load specifications before choosing snow retention products. While pad-style guards generally support up to 45 pounds per square foot, bar or rail options are preferable in areas with greater snowfall.

Tailor snow retention options for complex roof layouts.

For roofs with distinct curves or unconventional shapes, use snow retention systems specifically designed for these profiles. If you are unsure, contact your roofing manufacturer for additional guidance to ensure proper installation.

Select snow retention systems compatible with your roof.

Select products specifically designed for your roof's material and construction. Use compatibility resources or digital selection guides to ensure a precise match and effective performance.

Match snow retention solutions to your roof’s appearance.

Opt for snow guards with finishes that align with your roof's color or style, such as powder coating or custom color matching. Though custom finishes might extend lead times, on-site finishing can lower costs and reduce project delays.

Install snow retention devices in patterns that maintain even weight distribution to prevent uneven snow accumulation.

Arrange snow guards to evenly spread the load of snow and ice over the roof. Use a staggered layout for pad-style guards, and run bar or rail systems continuously in straight lines—never in isolated sections. Always follow our spacing recommendations.

Request product samples to confirm fit.

Order samples of snow retention solutions to test their compatibility with your roof's profile, helping to avoid installation problems and ensure optimal performance. No minimum quantity is necessary for sample orders.

Plan adhesive installations for favorable weather windows.

Install time-consuming installations using adhesives—such as those for polycarbonate guards—for late spring or early summer, when daytime temperatures consistently stay above 50°F. Water resistance develops in several days, but full curing takes about 30 days. Avoid adhesive mounting on copper panels, as Surebond SB-190 is not suitable due to potential chemical reactions.

Incorporate ice control accessories where needed.

If ice dams or buildup are a concern, use ice management add-ons—such as aluminum stoppers in bar or rail setups—to block ice from slipping under rail systems, especially on tall-seam roofs.

Customize snow guards to match your unique architectural details.

Adapt snow retention devices to fit the unique shapes and features of your roof, maximizing both function and efficiency in winter weather.

Use installation techniques that protect your roofing warranty.

For standing seam metal roofs, choose snow guards that attach with clamps or adhesives, avoiding screws or nails. This method helps maintain the roof's warranty and minimizes the risk of water leaks.
