In Illinois, the cyclical nature of extreme temperatures significantly impacts roofing materials. Single ply roofing membranes, such as TPO and EPDM, are often utilized on commercial and low-slope residential structures, offering good flexibility to accommodate freeze-thaw cycles. The heavy snowfall experienced during winter months requires careful attention to drainage and the structural load-bearing capacity of the roof. Furthermore, the prevalence of high winds, particularly in the Chicago area, necessitates secure fastening and expertly sealed seams to prevent uplift and ensure long-term performance against the elements. Proper substrate preparation is also critical to prevent moisture intrusion during the more humid periods.
