Power Efficiency Guide

Roofs can absolutely have an effect on the<a></a> overall indoor temperature of a home. Let's start with color. The darker the color, the more heat it will likely absorb. Dark asphalt shingles, tiles, metal, and similar materials attract more light and absorb higher levels of heat. In the winter, this level of heat absorption does not change, which is a good thing. But in the summer, a roof' surface can reach up to 120 degrees Fahrenheit or more on 90 degree Fahrenheit day.Excess heat will travel into the attic or upper areas of the home, and eventually transfer into the living quarters, thus affecting the indoor climate and even monthly energy bills. Lighter roofing materials are more reflective than absorptive. They retain less light and heat, thus delivering steadier indoor temperatures on hot days. Regions that experience heavier or regular snowfall generally have darker roofs, while hotter regions generally have lighter roofs.
