Award-winning roofing projects highlight technical expertise, safety coordination and creative problem-solving across schools, airports, medical facilities and urban landmarks. 

Sika Roofing & Waterproofing has announced the winners of its 2025 Projects of the Year competition, recognizing standout roofing and waterproofing installations completed by contractors across the United States. The annual program honors excellence across multiple categories, showcasing projects that combine technical expertise, planning and innovation under demanding real-world conditions. 

Among the recognized projects was the Narbonne High School roofing modernization in Harbor City, California, completed by BEST Contracting Services Inc. The large-scale effort covered more than 55 buildings within the Los Angeles Unified School District and featured the first installation of Sarnafil Self-Adhered Feltback membranes in 60-mil EnergySmart. Crews coordinated work during off-hours to minimize disruptions within the active school environment. 

In Boston, Massachusetts, Commonwealth Building Systems earned recognition for the 500 Boylston Street project, which transformed a highly visible rooftop into a checkerboard architectural feature using Sarnafil membranes in White and Lead Grey. The installation required precise measurements and detailed layout planning to maintain consistent alignment across the roof. 

Educational facilities were a recurring theme among the winners. Hayden Building Maintenance Corp. completed a complex restoration at Albertus Magnus High School in Bardonia, New York, replacing aging roofing systems above occupied classrooms, athletic spaces and cafeteria areas while maintaining daily operations. Similarly, DG Roofing LLC completed a six-month replacement project at Carl Schurz Elementary School in New Braunfels, Texas using a torch-applied SikaShield modified bitumen system designed for long-term durability and energy efficiency. 

Several projects highlighted the logistical challenges of roofing active or highly visible facilities. J.Reynolds and Co., a Tecta America Co., replaced the elevated turbine roof atop Houston’s Hess Tower under difficult weather and access constraints. At Milwaukee Mitchell International Airport Concourse D, L. Marshall Roofing and Sheet Metal completed a roof replacement while working within strict Federal Aviation Administration (FAA) and Transportation Security Administration (TSA) protocols to avoid disrupting airport operations. 

Tri-State Commercial Roofing Corp. was also recognized for a large-scale roofing upgrade at Stryker Orthopaedics in Mahwah, New Jersey, where crews coordinated around ongoing corporate operations and installed more than 350,000 square feet of Sarnafil roofing systems engineered to meet strict performance requirements. 

The winning projects reflected a common emphasis on safety, coordination, durability and long-term building performance, showcasing the resilience needed for contractors to meet the growing technical demands placed on modern commercial roofing project needs.
