In addition, adequate maintenance of the secondary drainage system is essential to ensure its performance in the event of a failure of the roofing system. The rooftop system and membrane should be evaluated every 20 years to assess the need for replacement. Maintenance access points should be clearly identified in the plan for the system. Special training required to perform specific tasks is required for the appropriate person/consultant (entity) responsible for completing the specific maintenance activity.
