One of the most commonly seen impacts of sunlight on your home’s exterior is the fading of the color over time. Sunlight contains powerful UV rays that react with the pigments in the paint, slowly bleaching them out. This is most visible in dark or brightly colored paints, as the color will lose intensity slowly.
Over time UV rays from sunlight exposure can cause the paint on your home to fade. The finish of your paint job is designed to protect the paint, but as the finish is repeatedly subject to harsh and penetrating UV rays, it breaks down and exposes the paint. Once the protective finish has been broken down, the paint is no longer protected.
