Facility roof maintenance requirements and standards shall be performed by
personnel responsible for this task. An effective roof maintenance/management
program is the platform on which the roof repair work standards specified herein
are based. This UFC does not attempt to define standards for a maintenance or
management program, including inspection and diagnosis of roof components
and systems. The standards defined in this UFC relate to the actual repair
methods and materials to be used only. The appropriate personnel shall
determine the need for and appropriateness of repairs to roof components and
systems prior to referencing this UFC and performing the specified repair work.
