This report describes the effects of the approaching wind on fluctuating pressures acting on flat roofs. The wind pressures acting on the flat roofs fluctuate irregularly both in time and in space. The cladding and the main frames supporting the roofs should be designed considering these pressure fluctuations. The wind tunnel testing on the fluctuating pressures acting on the flat roofs are carried out in the boundary layer wind with 5 different propaties. The wind pressure fluctuations acting on the flat roofs highly depends upon the turbulence intensity of the approaching wind. The correlations of the fluctuating pressures are also affected by the turbulence intensity and the turbulence scale at the height of the roof.
