At McClurg Court, Clark
Roofing was chosen to replace the roof systems on twin towers in the heart
of downtown Chicago. Imagine traveling 450 feet vertically along an all
glass wall carrying 900 to 1,200 lbs. at a time. Add to that the special
challenges that strong and swirling winds pose to high rise buildings.
Using a hydraulically driven hoisting device we were able to carefully and
cautiously lift the new roofing material to the roof and lower the debris
safely to the ground. To secure the first layer of insulation to the roof
deck, we drove 11,000 specially designed mechanical fasteners 3" into
structural concrete. Using this fastening technique, we were able to
obtain the wind uplift resistance we were striving to achieve. The
remaining layer of insulation was fully adhered in asphalt, two fiberglass
base plies were installed and the Johns’ Manville modified bitumen roof
membrane, TriPly, was heat welded into place.
