Based on a field survey conducted in Chiba Prefecture after the typhoon Faxai in 2019, the authors evaluated the structural performance of the roofing materials of houses damaged by the typhoon. Since the variance of wind resistance investigated was very large and median of that might be less than the design criteria, the authors conducted an experimental study of the pull-out test using deteriorated wood assuming the roof base material. The test results showed that not only the deterioration but moisture content might be affect for the wind resistance.
