How Often Do Metal Roofs Need To Be Replaced?

Metal is one of the most commercially and residentially sought-after roofing materials worldwide. Despite being a tad bit expensive, its veritable advantages such as durability, strength, and style make the investment worth every penny. One of the best features of metal roofs is that they have a lifespan of 50 to 70 years, depending upon the quality of the material used and the prevailing weather conditions. Furthermore, being moisture-resistant, metal roofs do not hold onto moisture, making them impervious to water damage and fungus. Thus, they become even more long-lasting.

There are specific telltale signs when it comes to replacing a metal roof. You might be observing your metal roofing and assume that it needs replacement. Sometimes, a well-intentioned acquaintance might advise you on a roof replacement. However, the crux of the matter is that you should not replace metal roofs until it is the right time. Nevertheless, you must be wondering, when does that ‘right time’ arrive. So let us look at the few warning bells that indicate that your metal roof needs an immediate replacement.


It is noteworthy to remember that the typical lifespan of a metal roof ranges from 40 to 70 years. However, it is vital to remain vigilant and regularly check for warning signs like those mentioned below.

1. The Painted Finish of Your Metal Roof has Touched the 30-year Mark –

All the major steel panel manufacturers utilize a patented process to apply a painted finish called Kyner 500 tp standing seam metal panels. The painted varnish protects your metal panels from various elements and keeps the color intact. However, the standing seam metal roof has a 30-year paint warranty on the Kyner 500 finish. After the paint reaches its expiration date, you should start planning a metal roof replacement for your abode. It is noteworthy to remember that the expiration of the Kyner 500 finish does not imply that the finish is entirely evaporated. But, when you observe a lot of rush or discoloration on the metal panels, you gather that now is the time to bid adieu to your old metal roofing.

2. Unprecedented Damage to the Painted Finish on Your Metal Roof Panels –

Anything that damages, dents, or scratches your metal roof’s painted Kyner 500 finish will shorten its lifespan. Whether it is damage caused by uprooted tree limbs during torrential rains or a tradesman clumsily trodding over your roof, disruption to the Kyner 500 varnish means that your metal roof will need replacement anytime soon.

3. You Can Observe Wallowed Out Fasteners –

A screw-down metal roof has fasteners exposed through the top of the panels. Due to its lack of expansion and contractors, the fasteners have wallowed until they are too massive for the screws that hold the metal panels down. Thus, the simple correlation is that if you do not fix your wallowed fasteners in due time, your metal roofing will need a replacement.

In conclusion, metal roofs have excellent longevity, and you do not need to worry about their replacement for at least 30 years in normal circumstances. However, being watchful is the key, and you should keep checking for damages and opt for professional maintenance at regular intervals.
