Windstorm event hit several parts of Malaysia particularly in the Northern region has severely affected humans and causing damage to the properties as well as fatality. Disaster risk mitigation efforts should be exerted to reduce the disastrous consequences of windstorm to the housing sector in rural area. The main objectives of the study are to develop conceptual framework of wind risk mitigation for rural houses in Northern Peninsular Malaysia. Questionnaire survey using five points Likert-scale was distributed to two groups of respondents, namely the expert and community group in the study. A non-probabilistic sampling technique was chosen as a purposive or judgmental sampling and analysed using IBM SPSS statistics version 21. The secondary data on post windstorm survey shows windstorm event predominantly occurs during the month of April, May and October during the inter-monsoon period in the Northern Peninsular Malaysia tremendously damage the rural houses roof cladding, hence, replacement is needed. The relative importance index was introduced to analyse significant influence on pre-identified risk factors. Meanwhile, Spearman’s rho correlation was performed to ascertain the risk and threat among the variables in the wind hazard mitigation. Thus, framework on the wind disaster risk mitigation for rural houses in Northern Peninsular Malaysia derived risk identification rank, and also risk hierarchy and threats took place in mitigation phase. The risk identification rank showed implementation of design in rural roofing system as the most significant preidentified risk factor. The framework indicated that roles of codes on wind loading, wind disaster event and design implementation are significantly important in risk hierarchical and threat. A process cycle involved during the reconstruction phase to produce a good quality of rural houses. Challenges and preventive measures encountered throughout the process shall be taken into account required continuous improvement over time. Finally, this study shall benefit the policy maker and governance body in decision making and develop a guideline on the wind disaster risk mitigation.
