This paper describes the results of a study on wind resistance performance of clay tile roof. In order to get the wind resistance performance of clay tile roof, questionnaire survey on the construction methods were carried out to the clay tile roof construction companies. Pulling-up tests on clay roof tiles were carried out using roof specimens having 4x 4 or 5 x 5 clay roof tiles. Pulling-out test on the fasteners were also carried out. Probabilistic model on wind resistance performance of clay tile roof is constructed based on the data. Damage rate functions were derived based on the model for evaluation of wind resistance performance of clay tile roofs. Regionalized evaluation of wind resistance performance of clay tile roof is shown using the function. Damage ratio can be expected using the function to a given wind velocity.
