Solar Reflectance

Solar reflectance refers to a roofing material’s ability to reflect sunlight and reduce heat absorption. Higher solar reflectance values indicate better energy efficiency and cooler roof temperatures. Materials with high solar reflectance help reduce cooling costs and extend roof lifespan by minimizing thermal stress. In roofing design, solar reflectance is an important factor in selecting energy-efficient materials suitable for varying climates, including the mixed weather conditions found in Vancouver.
