Considerations for Adding Snow Guards to Exposed Fastener Roofs by Fabral

Assessing Snow Load Capacity

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

Aesthetic Integration and Color Matching for Roofs

When selecting snow guards, ensuring their visual appeal aligns with your roof's color palette is essential. Customers can order customizable color inserts for ColorBar and SnoCleat along with the system or create them from leftover roofing materials. Additionally, metal pad-style guards and rail systems can be powder-coated to match your roof's hue perfectly. For faster alternatives, consider local coating services or DIY painting, as powder coating may extend delivery times.

Strategic Snow Guard Placement

The effectiveness of snow guards heavily relies on their proper placement. Always consult the manufacturer's guidelines for the best layout. Our website offers resources like spacing guides and quote request forms to assist you. Avoid installing snow guards in isolated areas, such as directly above doorways or walkways, to prevent system overload and potential failure.

Waterproofing Techniques for Snow Guards

Applying a thorough layer of silicone sealant is vital for screw-mounted polycarbonate snow guards. Ensure the base is completely covered and press firmly to remove any air pockets. While metal snow guards and rail brackets typically come with waterproof gaskets, some installers add sealant around the edges for extra protection, although this step is not mandatory.

Ensuring Secure Anchorage for Snow Guards

Proper anchoring is essential for mechanically mounted snow guards. Affix them to a solid substrate, ideally using at least one inch of sturdy wood like plywood decking or purlins. For metal structures, attaching directly to metal purlins is the best practice. Avoid depending solely on the roof panel for support. Adhesive products can be used for less robust structures when additional reinforcement is not feasible.

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 the most suitable period. The recommended adhesive, Surebond SB190, requires approximately a month of temperatures above 50°F (10°C) for complete curing. Cold weather can halt curing, but rain is not a concern after 24 hours.
