Roofer in Los Angeles, California

Reflective surfaces are surfaces that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the surface) and high thermal emittance (the ability to radiate absorbed, or non-reflected solar energy).[1] Reflective surfaces are a form of geoengineering. The most well-known type of reflective surface is the cool roof. While it is true that cool roofs are mostly associated with white roofs, they come in a variety of colors and materials and are available for both commercial and residential buildings. Cool roofs, in hotter climates, can offer both immediate and long-term benefits including: Savings of up to 15% the annual air-conditioning energy use of a single-story building[4] Help in mitigating the urban heat island effect.[5] Reduced air pollution and greenhouse gas emissions, as well as a significant offsetting of the warming impact of greenhouse gas emissions.
