Commercial Roof Condition Reports decision points
Every condition report we produce begins with a roof zone diagram. The diagram divides the roof into numbered sections — drainage areas, membrane sections, parapet runs, penetration clusters, equipment groups. Every observation in the report is referenced to a zone number, and every photograph in the photo log is labeled with the zone number and compass orientation. A reader who has never seen the building can map any observation in the report to a location on the diagram.
