Project Details

After numerous failed attempts by contractors to correct recurring water intrusion incidents, the Port of Portland tasked Professional Roof Consultants, Inc. with conclusively determining the leak sources and providing recommendations for repair as well as budgetary cost estimates.  An exhaustive failure analysis of integral sloped glazing systems and metal panel roofing assemblies was performed along with numerous leak tests in conformance with ASTM and AAMA standards.  Careful study of the skylight assemblies lead PRC to determine that the leaks were ultimately the result of a systemic defect, but innovative repair concepts were developed which could provide long term correction, and met the strict criteria for the continual operation of the Airport concourses.  PRC provided expert services and submitted a report which was the basis for a successful construction defect mediation.
