The global Metal Roofing Market was valued at approximately $28.9 billion in 2024 and is projected to reach about $38.5 billion by 2031.With its long lifespan, energy-saving features, and sleek appearance, metal roofing is experiencing a surge in popularity. Whether you’re improving a residence or laying out a commercial building, metal roofs offer a fantastic blend of curb appeal, performance, and cost that homeowners and business owners love.Fading on metal roofing is generally low, slow, and largely dependent on the overall quality of products and finishes. Through advancements in coatings technology, most of the unsightly checks found in the paint of the past have been eliminated, keeping the roof looking beautiful for much longer.
In this blog, we’ll delve into the causes of color fading, how manufacturers design against it, and provide a comprehensive view of the pros and cons of a metal roof for your home or commercial building. Whether you’re preparing for a new installation or just researching your options, this article will help you make an informed decision with confidence.

Why Metal Roofs Can Fade
How Does Fading Happen? The culprit responsible for roof color fading can usually be attributed to extended exposure to the sun and UV rays, as well as inclement weather such as snow, salt air from a coastal environment, and acid rain. With repeated exposure, paint finishes can diminish, and color shades can change.
However, new technology for protective coatings has made modern metal roofs incredibly fade-resistant. High-performance systems, such as Kynar 500/Hylar 5000, are structured in multi-layer finishes that exhibit color retention of 30-40% over 40 years or more. Most homeowners tend to notice only 5–10 ΔE units of color shift at most, as most rooms are within this range. Few of these homeowners notice the visual difference at all.
To put this into perspective, a roof with asphalt shingles that only needs to be painted can lose 20 ΔE units in 7 to 10 years. With met
Pros of Metal Roofing
Durability and Longevity
Metal roofing has a lifespan of 50 years or more, while traditional roofing materials, such as asphalt, have a significantly shorter lifespan, with an average of 20-30 years. The multi-part construction – comprising steel, a zinc or aluminum coating, primer, resin, and finish – provides a lasting surface that maintains its appearance and resists cracking, warping, and corrosion.
Fade-Resistant Finishes
The premium finish is loaded with UV stabilizers, oxide inhibitors, and powerful resins for a long-lasting color. They’re also factory-tested for fading, which means they’ll hold their color longer compared to other roofing materials.
Energy Efficiency
Metal reflects the solar radiant heat to minimize heat absorption. A lighter-colored surface may reflect 70–80% of the solar energy received, helping to maintain the attic temperature at or below that of the outside air and, in the process, lowering cooling costs by 10–25%.
Low Maintenance
Metal roofs are virtually maintenance-free you need only clear the gutters now and then and give them a look over to make sure there are no loose screws or sealants. It grows no algae or moss, and rebound is not a statistic.
Eco-Friendly
Made of 100% recycled material and 100% recyclable at the end of its lifespan, metal roofing is a sustainable option. Directly installing on the roof grain can be an effective way of preventing additional landfill waste.
Cons and Considerations of Metal Roofing
Initial Cost
Metal roof materials and labor are more expensive than asphalt, typically by a factor of two to three. Yet when you consider longevity and energy savings, the lifetime price often evens out and even becomes cheaper in some cases over decades.
Fading Over Time
Even when it is slow, some fading can occur. That could be an issue for homeowners looking for long-term designer color consistency. One of the primary ways to minimize visible fade is by choosing high-end coatings.
Thermal Movement
Metal also expands and contracts as temperatures fluctuate, leading to loosening of fasteners over time. This can be easily overcome by installing slip-sleeve fasteners and thermal clips.
Noise Factor
Some types of metal can be louder when the rain or hail is falling, and there is less insulation. Mineral wool or foam insulation below the roof can diminish noise transmission.
Potential for Dents
Metal roofs are relatively damage-resistant, although they can be dented by hail or falling objects. Thinner materials (such as 26-gauge steel and copper) and more open-rib profiles are more susceptible to dents.
How Fading Happens
The fading of color on metal roofs is not a sudden event; it is a gradual and subtle process, often not apparent for several years. Fading proceeds in two phases. The first fade, typically occurring within 1-5 years, represents a slight decrease in shine or gloss. Ultraviolet (UV) light breaks down surface molecules and pulls volatile chemicals from the coating, which is what causes the smell. It’s most apparent in bold or densely saturated hues (think dark greens, deep reds, or charcoal blacks). The long fade typically begins around the 5-year mark and can last for decades. At this stage, the resin system of the roof begins to break down, leading to a lightening of the base color. Sometimes, with sound-quality paint systems—and particularly those listed as exterior architectural—roofs can retain 70% or more of their original pigment after 30 years. It’s also worth mentioning that fading is much less noticeable on light colors, such as beige, white, or light gray because the contrast isn’t as stark to the eye.
Comparing Metal to Other Roofing Types
| Roofing Type | Average Lifespan | Fade Resistance | Pros | Cons |
| Metal | 40–70 years | High (ΔE 5–10 over decades) | Durable, energy-efficient, eco-friendly | Higher upfront cost, possible noise |
| Asphalt Shingles | 20–30 years | Low (ΔE 20+ in 7–10 years) | Affordable, versatile | Fade quickly, frequent replacement |
| Wood Shake | 20–30 years | Moderate | Natural aesthetic | Prone to rot, fire concerns |
| Clay/Slate | 50–100+ years | Excellent | Timeless, long-lasting | Very costly, heavy |
Maintenance Tips to Minimize Fading
Being proactive in maintaining a metal roof can help slow the fading of its color and extend the roof’s appearance for longer. Start by washing the roof once a year with a soft brush and mild detergent free of abrasives. This removes pollutants, dirt, and any natural oils that could accelerate fading or cause staining. Complete a thorough examination of the roof’s surface every 3-5 years. Inspect for early chalking (powdering of the coating surface) and minor cracks, as well as coating wear. The earlier you get these right, the less likely you are to need small touch-ups or a complete reapplication before your lip tattooing has completely faded. The fading colors can be repainted or recoated on metal roofs using specialty finishes formulated for use on metal, restoring a fresh color while enhancing UV resistance.
Additionally, ensure your roof has adequate drainage to prevent standing water, which can cause coatings to break down. Pruning overhanging trees also helps to reduce debris collection and mold. These good habits can help maintain the sharp look of your metal roof for decades.
When Fading Is an Advantage
Ironically, not all fading is bad; plenty of homeowners fall in love with the gentle streaking of a metal roof. After a while, even a bright-colored finish can take on the friendly vibe of a more muted shade, adding a rural touch that boosts curb appeal. Some architects and designers don’t mind when certain coatings patina as part of an oxidation process, making metal look more natural or vintage. This slightly weathered look is especially perfect for farmhouses, coastal, and industrial homes. As long as fading doesn’t indicate a problem with the coating or suggest corrosion, it can be a positive aesthetic that complements the surrounding environment well.
Conclusion
Yes, metal roofs can lose their color, albeit very gradually, and often with darker hues. The pros of a metal roof, the long lifespan, energy savings, eco-friendliness, and low maintenance usually outweigh the potential color risk that metal roofing colors may fade over time.
