Summary: The high rate of heat transfer through the residential roof assembly exacerbates indoor thermal discomfort. Installing bulk insulation can improve thermal performance, but it also inhibits heat transfer. On the other hand, high-albedo roof tiles reflect heat at the roof surface. By evaluating the thermal-energy performance of a pitched residential roof assembly under a hot and humid climate, it was found that energy savings of 15.13% were achieved by switching to a high-albedo roof surface and 17.00% by adding bulk insulation to the high-albedo roof assembly.
