Dark coloured roofs captured by FLIR thermal camera

The Sizzling Impact of Dark Roofs and Urban Heat Islands

Dark roofs are popular in Australian urban areas but they come with a catch. Dark coloured materials absorb and retain a substantial amount of heat, increasing local temperatures, and fostering urban heat islands. Understanding the impacts of dark roofs on urban heat is crucial for developing sustainable solutions to mitigate their effects and building resilient cities. The
