Coloured aluminium roofing sheets represents the common roofing sheet for the most houses in Benin city. Different colours of aluminium deliver various impacts on the indoor environment. This study focuses on estimating the amount of heat gain and roof surface temperature obtained from different colours of aluminium . The paper hypothesizes that colour techniques could affect the thermal efficiency of aluminium roofs. The research was based on the simulation analysis applied on an actual room size with different colours (dark purple, green and orange} in the University of Benin, Benin-city. As a result, the findings affirm the hypothesis and show the significance of roof colour in the thermal efficiency of aluminium roof. This study contributes efficiently to the knowledge of the roofing design in the tropics. In addition, it will shed light on the economic sector and sustainability for optimum roofing concept particularly for low cost housing components in Nigeria.
