Overview

Diagnosis: Infrared scans were conducted at the site. Infrared photos show the wet areas, and are typically easily identified by the outline of the insulation boards that are wet. The areas were marked, and verified using core samples and moisture meter detection through the membrane.

Total roof area for Roof A – 42,000 sf

Total wet area for Roof A – 8,327 sf

During the final walk through after the scan, J Reynolds & Co., Inc. superintendent noticed some pitting on the metal deck under the wet areas. The areas were rusted through and the decking needed to be replaced.
