How Often Do Metal Roofs Need to Be Replaced?

Nov 6, 2022Blog

One of the biggest advantages of metal roofing that sets it above other materials is its long lifespan. Metal is incredibly durable compared to asphalt shingles or tiles and will last many years. But how often do metal roofs need to be replaced? Here’s some important information to keep in mind when it comes to metal roof lifespans.

How Long Is a Metal Roof Lifespan?

When properly installed, a metal roof can last around 40 years. It might even extend its lifespan to 70 years in ideal weather conditions and with regular maintenance. In fact, it could very well last the rest of your life if the installation was performed correctly.

Additionally, metal roofing lifespans can differ depending on the style. For example, a screw-down panel metal roof may last two decades or more, depending on how well-maintained it is. A standing seam metal roof, comparatively, can last roughly 50 years, with finish warranties lasting 30-40 years, on average. Knowing what type of roof you have can determine its longevity.

How Do I Tell If a Metal Roof Replacement Is Needed?

While metal roofing is largely resistant to corrosion, there are some instances of rust to look out for. A painted finish protects your panels from rusting, so if it ever becomes damaged or scratched, it will expose the metal to moisture.

While metal roofs can withstand high winds and extreme weather conditions, long-term exposure may eventually lead to problems. Constantly expanding and contracting from high heat can shorten metal roofing lifespans, while frequent snow can damage the finish in some instances.

Unfortunately, a metal roof replacement may be necessary if mistakes were made during the initial installation. An inexperienced roofing contractor may not have the essential training for the job, resulting in errors that require a replacement to fix. For example, incorrect measurements can lead to metal panels that are too big or small for your home. When it comes to residential metal roofing installations, always ensure that trained professionals handle them.

How Often Do Metal Roofs Need to Be Replaced?
