See the Snow Guards Compatibility Chart for Nu-Ray Metals NRM-7000 Exposed Fastener Metal Roofing Panels.

Combine the NRM-7000 Panel with a range of snow management products to effectively manage snow and ice buildup on your roof. The polycarbonate SnoBlox Deuce is a pad-style guard that secures snow and ice. In contrast, the SnowBreaker breaks the snow and ice into smaller, safer fragments as they descend from the roof. Install these snow guards using screws or adhesive, and we recommend 3M double-sided tape for the SnowBreaker. The NRM-7000 Panel is also compatible with the galvanized SnoBar and aluminum ColorBar snow rails, which utilize the 1.5-inch wide aluminum Tall ColorBracket for secure attachment, providing dependable snow management.

While only four screws per bracket are necessary, customers have the flexibility to use all six screws, particularly in regions prone to harsh weather conditions, ensuring a robust and reliable installation.

Considerations for Adding Snow Guards to Exposed Fastener Roofs by Nu-Ray Metals

Strategic Snow Guard Placement

The effectiveness of snow guards depends heavily on proper placement. Always follow our guidelines for optimal layout. Avoid installing guards only in isolated areas like above doorways or walkways, as this can overload the system and cause failure. Our website offers resources like spacing guides and quote request forms to assist you.

Ensuring Secure Anchorage for Snow Guards

Proper anchoring is crucial for mechanically mounted snow guards. Attach them to a solid substrate, ideally using at least one inch of sturdy wood like plywood decking or purlins. For metal structures, connecting directly to metal purlins is best. Don't rely solely on the roof panel for support. Adhesive products can be used on less robust structures when additional reinforcement isn't possible.

Aesthetic Integration and Color Matching for Roofs

When choosing snow guards, it is crucial that they visually complement your roof's color scheme. You can order customizable color inserts for ColorBar and SnoCleat with the system or create them from leftover roofing materials. Metal pad-style guards and rail systems can be powder-coated to match your roof color perfectly. For quicker options, consider local coating services or DIY painting, as powder coating may extend delivery times.

Assessing Snow Load Capacity

Understanding your roof's snow load capacity is essential when selecting snow retention systems. Meteorologists analyze historical data to determine regional snow loads. Generally, individual guards or screw-down rails are sufficient for areas with ground snow loads of 45 PSF or less. At the same time, regions with heavier snowfall should opt for rail systems.

Waterproofing Techniques for Snow Guards

Applying a thorough layer of silicone sealant is crucial for screw-mounted polycarbonate snow guards. Ensure complete coverage of the base and press firmly to eliminate air pockets. While metal snow guards and rail brackets typically include waterproof gaskets, some installers add sealant around the edges for extra protection, though this isn't mandatory.

Optimal Timing for Adhesive Snow Guard Installation

The timing of adhesive snow guard installation is critical. In North America, late spring or early summer is ideal. The recommended adhesive, Surebond SB190, needs about a month of temperatures above 50°F (10°C) to cure fully. Cold weather halts curing, but rain isn't a concern after 24 hours.
