Thermal images can narrow the area for further investigation, but core cuts or another approved test are what confirm concealed assembly conditions. We mark proposed test locations on the roof plan and review them with the owner before cutting. The site contact authorizes each opening, and we confirm how the area will be repaired the same day. A test should be placed where it can answer the question while avoiding drains, seams, equipment and other details that complicate interpretation.
At an approved opening, we inspect the layers, insulation and deck that are exposed, photograph the materials and record what is dry, wet, damaged or inconclusive. One test result applies to that location and assembly. It should not be extended to an untested roof section without supporting evidence. If the sample differs from the thermal pattern, we explain the uncertainty and may recommend another location or a different method. A roof condition report can preserve the image map, test points, photographs and unresolved questions.
Results can support repair, removal, maintenance or capital planning. We keep tests separate from repair quantities until approval. Limited moisture may suit a focused repair; broader findings may call for sampling or a replacement evaluation. Recover work requires separate review of moisture, layers, drainage and structure.
