Ballast System

If a ballasted system has been installed, make sure the ballast is evenly distributed.  Care should be taken when inspecting the ballast, reviewing the corners, perimeter, and around penetrations for bare spots due to the increased wind effects in these areas.  The ballast should be redistributed, taking care to not damage the roofing system.  If your inspections reveal that the ballast is being moved repeatedly, it may be necessary to place an interlocking paver system in these areas.  The even distribution of ballast can have a direct correlation to the longevity of a roofing system.
