F.J.A. Christiansen Roofing Co. Inc., Milwaukee, a Tecta America company, recently restored the roof system on Milwaukee's City Hall. Completion of the 3 1/2-year project was marked with a December 2008 ribbon-cutting ceremony to celebrate the $70 million restoration of the 113-year-old building.

As a National Historic Landmark, the building's original elements had to be maintained or restored, including ornate and decorative panels that were worn out or missing.

Although original drawings and plans facilitated replacement of architectural elements, installation wasn't always easy.
