Abstract: | The results of this study demonstrate the potential of the combined thermal IR-nuclear moisture meter roof survey technique described herein. Application of the technique at Dyess AFB, Texas, resulted in the detection of roof areas with entrapped moisture on 5 of the 128 buildings surveyed. Airborne thermal IR imagery proved to be a very effective means of identifying roof areas with potential entrapped moisture. Some false alarms were created by air vents on smaller buildings; however, prior knowledge of the position of the vents (i.e. during the examination of the imagery) would probably reduce this problem considerably. Not all the questions were answered. Information is needed to define the usefulness of the technique as a function of climatic conditions and roof types. In addition, more data are needed to help define the optimum time for acquiring thermal IR imagery for roof moisture surveys. |
