Capacitance Roof Moisture Inspections

Capacitance roof moisture meters can be used to trace leaks or perform a complete roof moisture inspection.

Tracing leaks is accomplished by taking readings in the problem area, noting the positive readings and their level and looking for the highest readings which often indicates the source.

Full roof moisture inspections are performed by taking readings on a grid pattern over the entire roof.  When a positive reading is found, additional readings are made in each direction until a negative reading indicates dry material.
