    Colorado is known for its long sunny days and beautiful sunshine. However, the ultraviolet (UV) rays from the sunlight can have a major impact on your home’s vinyl siding. 

    If you have seen that your vinyl siding has been gradually losing its color or has faded, don't worry, you are not the only one. A lot of homeowners in Colorado face this issue due to the intense amount of ultraviolet radiation. The vinyl siding color is affected as time passes. In this blog, we will look at the reasons as to how UV radiation can cause vinyl siding to fade. We will also discuss how this affects different colors of vinyl siding and how you can maintain your home's exterior look.

    UV Rays and Vinyl Siding- How the Sun Affects Your Home's Exterior

    Vinyl siding is made of polyvinyl chloride (PVC), a durable and weather-resistant material. It is a popular choice because it's low-maintenance and is available in a broad range of colors. It is regarded as strong against the elements of weather. One of the primary challenges with vinyl siding is the exposure to UV radiation from the sun. As the sun rays continuously hit the siding, the chemicals in the siding get broken down, causing the siding color to fade.

    In Colorado, altitude and clear skies allow for stronger UV exposure, and vinyl siding is especially vulnerable. Homes at high altitudes, like those in Denver and Colorado Springs, are exposed to stronger UV rays as the atmosphere is thinner.

    Why Does UV Radiation Fade Vinyl Siding Colors?

    1. Chemical Breakdown of Vinyl Siding

    The colors on your vinyl siding are typically created by mixing pigments into the plastic material during the manufacturing process. Unfortunately, the sun's UV rays cause oxidation, which is a chemical reaction whereby the molecules in the pigments break down. 

    So, the original color goes on fading. The process of degradation can be very slow. But it's inevitable when the siding has been exposed to intense sunlight for a long duration.

    2. The Role of Pigments

    Vinyl siding colors that are darker or more vibrant tend to absorb more UV radiation, resulting in them fading faster. Lighter shades and pastels, conversely, reflect more light and thus tend to retain their color for a longer time. Nevertheless, all vinyl siding will eventually fade, even though it may take longer for some colors.

    Best Vinyl Siding Colors for Colorado Homes

    When choosing vinyl siding colors for Colorado homes, it is important to consider not only aesthetics but also how well the colors will stand up to UV exposure. Here are some colors of vinyl siding that generally remain vibrant in the sun, in intense places like Colorado.

    1. Light Colors

    Shades like beige, light gray, or pastels are less prone to fading under UV radiation. These colors reflect the sunlight instead of absorbing it, thus they are a perfect option for the houses located in the sunniest areas.

    2. Neutral Colors

    Neutral vinyl siding colors like taupe, off-white, or light brown are classic and tend to fade more slowly compared to darker hues. These colors go perfectly with both rustic and modern styles of homes.

    3. Darker Colors

    Deep blues, greens, and burgundies may give an amazing touch to homes;  however, they are more prone to fading when exposed to high levels of UV, especially in Colorado. These colours absorb more heat and light, which can lead to more rapid degradation.

    Can You Paint Vinyl Siding?

    One question many homeowners have is whether they can paint vinyl siding to restore its look once it begins to fade due to UV exposure. The answer is simple: yes; however, there are some limitations. In essence, you can paint vinyl siding; it is essential to choose the right kind of paint. The best choice is acrylic latex paint made specifically for exterior use on vinyl.

    Painting your vinyl siding can be labor-intensive and may not last as long as the original color. Also, if your siding has started to degrade from UV exposure, painting may not address underlying structural issues that can lead to further fading or damage.

    Did You Know? 

    UV Rays Affect More Than Just Your Vinyl Siding!

    UV rays don’t just cause your vinyl siding to fade; they can also damage other elements of your home’s exterior, such as roofing materials, windows, and decking. Over time, prolonged exposure can lead to brittleness and cracking. 

    The constant exposure to the sun can cause the material to crack and become brittle. To ensure the structural integrity of the exterior of your house, it is recommended to use reflective coatings that resist UV, paints and even shading devices like awnings that protect your walls.
