Abstract
Wind loading on roofs remains to be a complex phenomenon and one of most common factor in roofs failure. This is mainly due to the fact that wind-flow conditions around buildings and wind-induced effects on such buildings have dynamic characteristics that are time and space related. From a space perspective, the wind’s characteristics are affected by aspects such as building geometry, site topography, and architectural features. From a time perspective, the wind dynamic characteristics are affected by wind speed, turbulence intensity and wind direction. It must also be noted that roof is subjected to wind induced negative pressures on the exterior and positive pressures acting on the underside as shown in Figure1
