A Fresno home replaced dark asphalt shingles with reflective concrete roof tiles; a Lawrence Berkeley study reported 26% lower annual cooling energy use and 37% lower peak-hour demand

A recent study in Fresno demonstrated that reflective roofs could lower cooling energy consumption by an impressive twenty-six percent. Homeowners experienced a peak cooling demand decrease of thirty-seven percent, resulting in significant savings. The reflective material absorbs much less sunlight compared to traditional dark shingles, and the study also revealed minor benefits for winter heating. Effective installation with proper airflow is essential for achieving these energy-saving results.
