ASTM-D7053/D7053M 2017

1.1 This guide describes methods for determining and evaluating causes of water leakage in low-sloped roofs. For this purpose, water penetration is considered leakage and therefore problematic, is causing or is likely to cause premature deterioration of the roof, building or its contents, or is adversely affecting the performance of other components of the building. A roof is considered an assembly including the membrane, insulation, vapor retarder (if required), deck, and structural components.

1.2 Investigative techniques discussed in this guide may be intrusive, disruptive, or destructive. It is the responsibility of the investigator to establish the limitations of use, to anticipate and advise of the destructive nature of some procedures, and to plan for repairing and selective reconstruction as necessary.

1.3 This guide does not address steep-sloped roofs, standing or flat seam metal roofs, or architectural standing seam metal roofs.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
