Western Roofing Service replaces the roof on a United Airlines maintenance facility

San Francisco International Airport has made clear its dedication to the environment. Its 2005 annual review provides examples of the airport's efforts, including increasing the number of airport vehicles that use clean power and reducing post-emergency pesticide and herbicide use.

So when United Airlines decided to replace the 20-year-old roof system on its maintenance facility—which had been experiencing leaks—at San Francisco International Airport, energy efficiency was an important factor. United Airlines also wanted a durable roof system that effectively would protect the daily operations inside the facility.

Western Roofing Service, San Francisco, a Tecta America company, was chosen to remove and replace the building's existing built-up roof (BUR) system.
