Compared to other materials, metal roofs are far superior when it comes to longevity and durability. It’s also resistant to extreme weather conditions. To prolong its lifespan, you need to choose a good metal roof paint. Applying the right primer, paint, and sealant can keep the roof performing at its best.
Like any other painted surface, the color will start to get dull over time. Chalking and fading are both natural processes. This blog will take you through why fading occurs and factors that may affect your metal roof’s color.
Why do metal roof colors fade over time?
Over time, environmental elements and substances interact with the paint pigments on your metal roof. The pigment will begin to break down and fade from excessive exposure to the sun.
Metal roof fading is common since the surface gets exposed to harsh elements. When not addressed, this can shorten your roof system’s lifespan. The paint system will no longer be effective in protecting the metal panels from corrosion.
Factors That Contribute to Metal Roof Fading
- Lack of Shade
- Mold and Algae Buildup
- Quality of the Paint System
- Extreme Weather Conditions
- Exposure to UV Rays from the Sun
Which paint colors will fade less?
Fading occurs with any color, but some colors fade much quicker than others. When installing a metal roof, it’s very important to select the right color. As metal roofing experts, we have some recommendations on how to make color fading appear less obvious.
Dark hues and vibrant colors fade faster than others. In fact, the color that’s most susceptible to fading is red. If you want a color that lasts longer, avoid choosing yellow, orange, and red. These paint colors fade faster because their pigments react with chemicals in the environment. They also have less pigment, which is why the color gets washed out easily.
In contrast, neutral tones like beige, tan, and white are less susceptible to fading. Lighter colors do not absorb many ultraviolet rays from the sun. That’s why the paint won’t prematurely fade or peel. Regardless of the color, choosing high-quality paint can make all the difference.
Organic vs. Inorganic Pigments: Which is better?
Paint colors are made from either organic or inorganic pigments. In terms of chalking and fading, inorganic pigments are less prone to losing their color. Lighter paint colors typically have pigments that do not break down easily.
Organic pigments tend to be brighter and more vibrant than their inorganic counterparts. On the downside, organic pigments are usually more prone to fading. When exposed to sunlight, the color will chalk and be less apparent.
Matte vs. Glossy Finish: Which is better?
The difference between matte and glossy finish is the reflectivity. The glossier the paint, the more it will reflect light. Paint colors with glossy finishes absorb fewer UV rays, which causes chalking and fading. You can expect glossier paints to have a stronger visual impact and more durability.
On the other hand, matte finishes offer nearly zero reflectivity. With matte formulations, the pigments are more exposed to the sun. Because of this, matte paint colors are less resistant to fading.
How to prolong your metal roof’s paint color?
Chalking and fading of metal roofs are unavoidable, but there are ways you can minimize the damage. Here’s how you can keep your metal roof looking sharp and flawless:
