Common issues with EPDM roofs include which of the following?

EPDM (Ethylene Propylene Diene Monomer) roofing systems can face various common issues, with one prominent concern being open seams and flashings. This problem typically arises due to the inherent flexibility and expansion-contraction properties of EPDM materials, which can lead to stress at seam joints and flashings over time. If these seams fail, water can penetrate the roofing system, resulting in leaks and potential water damage to the underlying structure.

Seam integrity is crucial for the overall performance of EPDM roofs; therefore, proper installation techniques and regular maintenance are essential to ensure that seams remain intact and watertight. Monitoring the condition of flashings, which are critical points of vulnerability at transitions and terminations, also helps to mitigate the risk of failure in these areas.

Other issues like curling edges and peeling can occur but are less common compared to the challenges associated with seams, particularly if the roof is maintained correctly and installed according to manufacturer specifications. Likewise, excessive weight accumulation is more characteristic of different roofing materials, and rusting of metal flashings is an issue typically associated with metal roofing systems rather than EPDM. Hence, the identification of open seams and flashings as a significant concern underlines the importance of proper installation, inspection, and repair
