Choose your city
Illinois' climate presents significant challenges for EPDM roofing. The extreme temperature swings between hot, humid summers and bitterly cold winters can cause considerable expansion and contraction, putting stress on EPDM seams. Heavy snowfall and ice accumulation in winter, coupled with intense summer rains, demand a meticulously installed and sealed roof. For Chicago homeowners, ensuring the integrity of EPDM, particularly on the prevalent low-slope or flat roofs, is essential for preventing leaks and protecting their property throughout the year.
Common questions
