Heat-Reflective Roofing in Perth
Perth's extreme summer heat (40-degree days are common) makes Colorbond's Thermatech solar-reflective finish a worthwhile upgrade for Perth roofs; lighter Colorbond colours (Surfmist, Shale Grey, Dune) can reduce roof surface temperatures by 10-15 degrees compared to darker colours, reducing ceiling and attic heat load
