The another day I did a roof certification on a house with a tile roof. The homeowner called us because the insurance Co. sent out their own inspection firm. He claimed there was leakage in the roof deck at the rear half of the building. He left themal images behind as proof, taken inside the attic.
There is no evidence for any leakage in the area if he identifed as the problem. The day he was there is had rained earlier on (ponding on flat roof, the real problem) and the roofing was drying out, leaving some areas of roof sheathing colder. The tile roofing is 13 years old…another expert with a thermal camera.
