A sagging roof section at the Therma-Tron-X plant at 1155 South Neenah Avenue in Sturgeon Bay, caused by the weight of the recent snowfall, led to a call to the fire department asking for help in the snow removal Tuesday afternoon. The department responded at 12:19 and determined that the roof section was sagging in an area close to a two inch gas pipe, communications and electrical service to the company offices and shop area. The department’s aerial truck was used to systematically direct streams of water to the snow-covered roof, starting at the bottom and working up. A nearby storm drain collected the water and a work crew removed the ice chunks. In all, 62,350 gallons of water was used during the operation. Before fire crews left the scene at 3:18PM, they checked the roof section that had sagging and determined that it had lifted by about three inches, indicating that the stress caused by the heavy snow had been relieved.
