Roofing for the Iconic Rookery Building

The Rookery was designed by Daniel Burnham and John Root with Frank Lloyd Wright redesigning the Light Court shortly after the building was opened. In 1970, the Rookery was placed on the National Register of Historic Places and declared an Official Chicago Landmark in 1972.

The re-roofing project at this landmark building presented logistical and scheduling issues that necessitated the work be performed by a highly experienced roofing contractor. With work being performed in the middle of the financial district, tight restrictions were placed on timing of debris removal, material delivery and noise-producing work. The work area involved a low slope roof in the center of the building and a 5/12 slope roof around the perimeter. The low slope roof surrounded a huge skylight and the sloped areas held extensive ductwork, adding another challenge to the re-roofing project. Custom fabricated sheet metal flashings were installed, accenting the extensively detailed structure.
