Learn how these award-winning projects demonstrate technical precision, collaboration and innovation across complex roofing systems. 

Sika Roofing & Waterproofing’s 2025 Projects of the Year Awards offer a clear view into how contractors are meeting rising expectations for performance, durability and architectural integration. The annual competition recognizes application excellence across Sika’s approved applicator network, drawing submissions from across the country in categories including low-slope, steep slope, waterproofing and sustainability. 

Samuel Oschin Air and Space Center 

The 2025 winners reflect a broader shift in the industry, where complexity is no longer situational but inherent to the work itself. That reality is evident in the Samuel Oschin Air and Space Center in Los Angeles, California, where Letner Roofing Company executed a roofing system designed to meet both technical and visual demands. The approximately 200,000-square-foot expansion, built to house the Space Shuttle Endeavour, required more than 55,000 square feet of Sarnafil PVC membrane installed across five distinct roof levels. 

Each section required a different approach. A ballasted assembly with Mexican black pebbles delivered a clean, finished appearance while supporting efficient installation, while other areas demanded precise detailing around pre-installed ductwork and complex wall transitions. At higher elevations, multiple systems were integrated, including Sikaplan membrane for interior protection and a Sarnafil Décor Roof system engineered to replicate the look of standing seam metal, ensuring consistency across both performance and design. 

QTS New Albany 1 (NAL1) DC1 

That same emphasis on system integration carries into the QTS New Albany 1 (NAL1) DC1 data center in New Albany, Ohio. Completed by Cotterman & Company Construction, the 240,000-square-foot facility was built to support mission-critical operations where failure is not an option. The roofing assembly was designed as a unified system, combining layered insulation, vapor barriers, leak detection and a 72-mil Sarnafil PVC membrane. Extensive expansion joints and perimeter detailing were incorporated to manage movement and maintain long-term reliability across the structure. 

These projects demonstrate how roofing has evolved within modern construction. As buildings demand greater coordination and higher performance thresholds, roofing systems are increasingly defined by how well they integrate with the broader structure. The 2025 winners represent that shift in practice, setting a higher standard for execution across the industry.
