Your roof is the last line of defense for your family and property from severe weather elements. However, the roof also contributes to your house’s curb appeal and overall market value. Therefore, you want to choose a strong roof with a vibrant color that will remain bright for a long time without regular maintenance. So, what color metal roof lasts the longest?
It is not easy to pick a particular color of metal roof that will last the longest. Generally, metal roofs with light colors last longer than darker ones. It depends on several factors, like the color pigmentation and the ending. Let’s look into several factors that affect the longevity of your metal roof.
Roof Color Pigmentation
Most dyes and colors fade when exposed to direct sunlight. The sun’s ultraviolet photons are powerful enough to ionize the color pigments and the oxygen in the air at the roof’s surface, causing oxidation. As explained below, the rate at which metal roofs of a particular color faint closely relates to the pigment’s origin and composition.
Organic vs. Inorganic Compounds
Color pigment’s chemical composition plays a significant role in how it fades. For example, pigments with organic compounds like carbon break down much easier and quicker, fading faster.
You’ll find them in darker and more vivid colors, such as red, blue, and black. Conversely, inorganic compounds in lighter colors from natural rocks are harder to break down and take longer to fade.
Paint Finish Matte vs. Glossy
You are better off with a roof with a protective coating that extends its service life and maintains its vibrant color. Some roofs are coated with a special acrylic resin to block ultraviolet rays preventing fading, corrosion, and rust. It works well with glossy paints, which dry with a protective layer over the pigments.
We also recommend the application of several coating and sealant layers as additional protection during repairs to make your roof last longer.
