Roof collapse due to wind load impact on roof sheeting during thunderstorm event was reported by media. In most cases, failure of roof sheeting based on two points, either on material roof sheeting or at connection of roof sheeting. It was observed that the most failure of roof sheeting is likely occurred for non-engineered building. Base on MS 1553: 2002 wind load for building structure, structural elements should be able to resist wind speed up to 32.5 m/s. Therefore this study is conducted to identify the possibility of the pull-through failure of nail connection with Corrugated Galvanized Iron (CGI) roof sheeting for non-engineered buildings. This study is focus on the connection between roof sheet metal and nail connection with various spacing between the connections. Finite Element Method was used in this study to analyse and identify the load distribution. From the result it shows that the maximum spacing of nail connection is 480 mm to resist the wind load recommended by MS 1553: 2002. From the result it can be concluded that as the spacing of connection increases the failure of CGI metal roof also increases.
