What snow retention systems are best suited for Marco Metals’ standing seam panels?
Standing seam metal roofing is known for its sleek appearance and high performance. However, during winter, it can become a safety hazard when snow and ice suddenly slide off the roof.
These rapid releases, commonly called roof avalanches, can endanger people, pets, vehicles, and landscaping below. To reduce these risks, it's important to select snow retention systems tailored to the roof's profile and fastening method. For concealed fastener panels, product-specific guidance ensures a secure fit and dependable performance. This blog series explores compatible snow guard options for various panel types and highlights trusted metal roofing brands to help readers make safe, informed decisions.

Considerations for Adding Snow Guards to Standing Seam Roofs by Marco Metals
Using systems built for unusual roof shapes.
Architectural designs with curves, angles, or non-standard features may require tailored snow retention solutions. Always consult your roofing manufacturer to determine the most suitable system for your specific layout.
Apply adhesives in the correct season.
Contractors should only install adhesive-mounted snow guards when temperatures exceed 50°F to ensure proper curing, which typically takes 28 days. Moisture resistance begins within the first 24 hours. Avoid using Surebond SB-190 on copper due to incompatibility.
Verify that guards suit your roofing system.
Make sure the snow guards you choose are compatible with your roof’s material and profile. Our compatibility charts can help you avoid mismatched installations and ensure a secure fit.
Select roof finishes that complement your roof.
Choose powder-coated or custom-colored finishes that align with your roof’s aesthetic. DIY options may offer quicker turnaround, while custom colors often require additional lead time.
Adjust installation for complex roof details.
Adapt snow guard placement to suit valleys, pitch transitions, and other intricate roof features. This practice helps maintain consistent snow retention and minimizes the risk of failure in vulnerable areas.
Follow installation methods approved for warranties.
To maintain your roof’s warranty, use non-penetrating mounting techniques such as adhesive or clamp-on systems, especially for standing seam panels. These methods help prevent leaks caused by fasteners.
Account for regional snow load requirements.
Before selecting a snow retention system, consult local building codes to determine your area’s ground snow load. Pad-style guards typically support up to 45 pounds per square foot, while rail systems are better for heavier snow conditions.
Order sample snow guards for test-fitting.
Individual sample guards are available without a minimum order. Testing a sample on your roof helps verify fit and reduces the risk of costly installation errors.
