Since 2016, San Antonio has replaced dark roofs on low-income homes with reflective shingles; the program was linked to lower attic temperatures and electricity use

San Antonio has launched an innovative project to replace traditional dark roofs with energy-efficient reflective roofing. This initiative has resulted in over a ten-degree Fahrenheit reduction in average attic temperatures. Furthermore, homes involved in the program have experienced a notable 7.3 percent drop in electricity usage. Targeting low-income neighborhoods disproportionately affected by heat, this simple yet effective solution provides both cooling relief and financial savings.
