The IICRC WRT body of knowledge stresses thatdocumentation is a critical component of professional water damage restoration, and restorers are expected to obtain and maintain documents that validate drying progress and project completion. These records demonstrate that drying goals were properly established, monitored, and achieved in accordance with the ANSI/IICRC S500 Standard.

Drying documentation typically includes moisture content or moisture level readings, moisture maps, psychrometric data (temperature, relative humidity, humidity ratio, and dew point), equipment placement records, and daily monitoring logs. Together, these documents form a defensible record that shows the restorer followed an appropriate standard of care.

The WRT manual explains that such documentation is necessary not only for communication with materially interested parties (owners, occupants, insurers) but also for dispute resolution, quality assurance, and potential legal proceedings. Without validated drying documentation, it is difficult to prove that materials were returned to a dry standard or that secondary damage was prevented.

AHAM certificates may be useful for understanding equipment performance, but they are not required project documents. Law enforcement permission and historical restoration records are unrelated to the drying verification process. Therefore, obtaining documents that validate drying and completion is the correct and required practice under WRT guidance.
