What is the typical flashing material used for an EPDM single-ply roof?

Metal
EPDM
PVC
TPO

The correct answer is: EPDM

The typical flashing material used for an EPDM (Ethylene Propylene Diene Monomer) single-ply roof is EPDM itself. This is because EPDM roofing systems are designed to be seamless and fully adhered, allowing for the use of the same membrane material for flashing details. Using EPDM for flashing ensures compatibility and adhesion properties, which are critical for preventing water infiltration at vulnerable areas such as roof penetrations, edges, and seams. When the same material is used for both the roofing membrane and the flashing, it minimizes the risk of leaks, enhances the performance of the roof system, and simplifies the installation process. Other materials such as metal, PVC, and TPO may be used in different roofing systems but are not typical for EPDM applications due to concerns about compatibility, different thermal expansion properties, and bonding issues. Thus, using EPDM for flashing maintains the integrity and durability of the entire roofing system.
