Roofing for River City Condominiums

The River City Condominiums are located on the Chicago River in the up-and-coming South Loop neighborhood. The building designed by Bertrand Goldberg as a “city within a city”, was built to support the residents’ health, education, day-care and recreation facilities. As the original roofs on this distinctive S-shaped building reached their end of life, units were facing recurring problems with water infiltration.

Knickerbocker removed the existing roofing and installed insulation, coverboard and Sarnafil’s EnergySmart PVC roof membrane and flashings at the 19 different odd-shaped roofs. There were also thousands of feet of challenging liquid membrane flashing that added significant complexity to the project at the serpentine multi-level building. Material was double, triple and even quadruple handled with cranes, hoists and manpower to reach the various roof areas without impacting the residents. Safety was a critical component of the project and there were no injuries to workers or residents for the duration of the project.
