Increasing solar reflectance on roofs is an efficient strategy for urban cooling. The aim of this study is to evaluate how the passage of time affects the thermal behavior of 19 roof tiles and roof paint. The impact of aging is quantified by the change in the Solar Reflectance Index over three years. The results show that the roof coatings evaluated tend to increase the surface temperature between 3.5 degrees C and 24 degrees C. The main morphological characteristics that impact the thermal performance of new materials are: color, composition and finish; while for aged materials are: color, finish and shape.
