Which snow guard systems are most effective for Garco Building Systems’ standing seam panels?
Standing seam metal roofing offers a modern appearance and dependable longevity. Still, it also brings specific safety challenges in climates with regular snowfall.
Managing snow movement is essential to reduce winter-related risks. When snow and ice suddenly release in large sheets, commonly called a roof avalanche, they can cause extensive damage to anything below. Vehicles, landscaping, walkways, and outdoor equipment are all at risk, and the sudden drop can also pose a danger to people and pets. To minimize these hazards, installers rely on snow guards and bar-style retention systems that match the roof panel's geometry and attachment method. Because concealed-fastener profiles require solutions tailored to their specific shapes, choosing the right snow retention system is vital for long-term performance and safety. This blog highlights the snow guard products that pair well with Garco Building Systems' standing seam panels, helping you make informed decisions for your project.

Considerations for Adding Snow Guards to Standing Seam Roofs by Garco Building Systems
Account for local snow load standards.
Check regional building requirements to confirm your snow-retention setup meets the necessary load ratings. While pad-style guards often support up to 45 pounds per square foot, areas with heavier winter conditions may require stronger rail-based systems.
Apply adhesives during the correct weather window.
You should only install adhesive-mounted guards when outdoor temperatures remain above 50°F for a continuous 28-day period. Although the adhesive becomes moisture-resistant after about 24 hours, it takes about 4 weeks to cure fully. Avoid using Surebond SB-190 on copper panels, as it can accelerate premature corrosion.
Use systems tailored for unique roof shapes.
Roofs with sharp pitches, curved sections, or other unusual geometries often call for specialized snow-retention solutions. Consult your roofing supplier to determine which system best fits these nonstandard configurations.
Order sample snow guards for test-fitting.
We sell samples on our website with no minimum quantity, allowing installers to test-fit guards directly on the roof. This practice helps confirm proper alignment and sizing while reducing the risk of installation errors. Always follow the manufacturer's instructions to preserve warranty coverage.
Adapt installation for complex roof features.
Snow guard placement may need to be adjusted to work around valleys, slope transitions, and other architectural elements. Correct positioning in these areas is essential to maintaining system performance and preventing issues later.
Verify that guards match your roof design.
Choose snow guards engineered for your roof’s specific panel profile and material. Compatibility charts help prevent mismatches and support long-term system reliability.
