Roof Replacement Program

Evanston Township High School consists of numerous buildings and facilities on a 65-acre campus site in Evanston, Illinois. The main buildings and facilities are located on the eastern portion of the site, with parking lots and athletic fields and facilities on the western portion of the campus. The dates of construction of the buildings vary, beginning in the early 1920’s through the mid 1960’s. The majority of the building facades are clad with clay brick masonry. Terra cotta and limestone ornamentation is used at various points throughout the facades and metal-framed windows and curtainwalls of various configurations and sizes are used in the building facades.

Over the years the roof replacement program for the various buildings on campus has addressed installation of a 2-ply modified bitumen roof membrane system

• Removal of the existing roof systems and associated components

• Replacement of drain heads

• Installation of a temporary roof vapor barrier

• Installation of flat or tapered insulation, underlayment, base and cap sheets with integral flashings and sheet metal counterflashings
