Roof Moisture Survey Report
This is an example of an actual roof moisture survey report. The in-place construction of the roof assemblies that were surveyed consisted of (from bottom to top) a wood plank or structural concrete deck, two coal tar pitch built-up roof systems with wood fiberboard or perlite insulation, 3 inches of spray polyurethane foam, and a silicone coating with embedded granules.
The survey was performed using both infrared thermography and nuclear moisture detection technology. The survey was performed by an excellent non-destructive testing services company, Infra-red Analyzers, Inc. (www.iranalyzers.com).
