About this video:

A ballasted EPDM roof is a roofing system commonly used for commercial buildings and high-end residential properties. The EPDM membrane is covered with ballast, usually rounded river rock or concrete pavers. The weight of the ballast holds the membrane in place and protects it from wind uplift and other environmental factors.

Inspectors are not required to move ballast to inspect the EPDM membrane beneath. However, some ballast could be moved from windscouring, uneven distribution, or past repairs. Exposed membranes should be assessed and reported on. Other areas of concern include parapet walls, flashing and penetrations, seams, blocked drainage, and debris. Take the Inspecting Low-Slope Roofs Course to learn more about inspecting ballasted roofs.
