Common Question: Will the color of painted metal roofing panels fade out in a year or two?
Constant exposure to UV light breaks down chemical bonds in the colors of any object left in sunlight and thus causes fading. This process is known as photodegradation. Just like anything left to the endless daily punishment of UV light from the sun, painted metal roofing will fade to some extent over time. When purchasing your new painted metal roof, it is extremely important to know what type of paint is applied to the metal roofing. Choosing the correct type of painted metal roofing will protect your investment and ensure you have a beautiful roof for years and years to come. There are three main types of paint that is applied to metal roofing; polyester, siliconized modified polyester, and Fluorocarbon-based paints.
Polyester paints are by far the cheapest paint and as to be expected have the lowest resistance to fading. Polyester painted metal roofing typically comes with a paint fade warranty ranging from one to five years. Some suppliers market polyester painted metal roofing as prime forty-year warrantied products. This makes pricing very attractive to the consumer but, in the end leads to extreme disappointment in the performance of the metal roof. You have heard the saying before, and when it comes to painted metal roofing it holds true. You get what you pay for.
Siliconized modified polyester or SMP uses polymerized silicone to vastly improve fade resistance and gloss retention when compared to polyester paints. You will not find a better SMP paint than Valspar’s WeatherXL line of paints. Echols Metal offers you quality metal roofing coated with Valspar’s WeatherXL or WeatherXL Crinkle Finish line of vibrant paint colors. All WeatherXL paints are designed for long lasting durability and extreme fade resistance. Valspar WeatherXL painted metal roofing is always applied with a primer layer and not one but, two top coat layers. WeatherXL paint carries a forty-year warranty and not only ensures fade-resistance but also increases the corrosion resistance of your metal roofing panels.
Fluorocarbon based paints implement a much more expensive technology and are a completely different chemistry from SMP paints. Due to the extreme cost of Fluorocarbon based paints, they are typically reserved for larger commercial projects that demand the most ultimate level of fade protection.
