When quality, design and warranty align: Raising the standard for snow retention

By Heidi J. Ellsworth.

TRA Snow and Sun explains why engineering and attachment matter more than weight alone.

With winter in full swing, contractors begin hearing from building owners who suddenly realize their roofs need snow retention before major storms arrive. Although these systems are ideally installed earlier in the season, late-fall demand continues to surge. TRA Snow and Sun has become a trusted expert source during this busy period, providing contractors with clear guidance on what truly drives snow retention performance.

Across the industry, misconceptions about strength persist. Many still believe heavier automatically means stronger, yet snow guards can range from thin 26-gauge components to oversized cast pieces without guaranteeing better results. Real strength comes from smart geometry, quality materials and, most importantly, the attachment method. Leading engineers design, test and warranty systems for specific project layouts so brackets, rails and fasteners perform as an integrated whole.

Precision, not bulk, is the true differentiator. Rigorous test protocols reflect real snow loads and actual movement, giving contractors a clear picture of how a system will behave when winter arrives. This engineering-first approach has helped elevate industry expectations and improve outcomes on a wide range of roof types.

Experts also emphasize practical insights that save time and money on the roof:

• Mechanically hemmed standing seam panels can offer up to 71% stronger attachment, potentially reducing system costs by as much as 30 percent.
• Screws outperform nails for bracket installation and can double system strength.
• Many roofs do not require a two-rail fence when a one-rail or hybrid setup can deliver the same performance with fewer materials.
• On more complex structures, combining brackets with snow fences can create an effective dual-system approach.
• Thoughtful design is what sets high-performing snow retention products apart. Systems developed through engineering provide predictable protection.
• Using 16-gauge steel chosen for reliability, today’s top solutions incorporate the right amount of material instead of unnecessary bulk. Project-specific warranties reinforce confidence, and true savings come from efficient design rather than shortcuts.

Daily testing continues to refine performance and strengthen industry knowledge. Whether a project calls for 24-gauge components or heavier 3/8-inch steel, well-engineered systems are designed for longevity and dependable performance. The goal remains consistent: to give contractors solutions that install efficiently, look clean and perform for decades.

For contractors seeking dependable snow retention options, TRA Snow and Sun offers engineered systems for nearly every roof type along with free design support, project-specific layouts and warrantied performance.
