Lifespan of a Metal Roof

Metal Roof Lifespan

Nothing lasts forever, but the right choice of metal roofing can endure for many lifetimes. Just take a look at some of the roofs atop cathedrals and castles in Europe! If priorities for your roof include low maintenance and longevity, metal should be one of your first choices. So, just how long will your metal roof last? Let’s take a look!

Metal Material

Overall, the longevity of your metal roof will depend on which metal you decide to go with. Galvanized metal, for example, can last at least 50 years. Perhaps even more, as the practice of galvanizing is only 60 years old! Copper roofs are considered to be the best roofing material in the industry due to their longevity and durability. These roofing systems can last 100 –  even 200 – years, easily withstanding wind, saltwater, and more. Steel roofs, on the other hand, can last up to 75 years, while zinc roofs can last longer than 100! Aluminum roofs last the least amount of time compared to other metals, often lasting up to 50 years.

Lifespan Factors

Other factors affecting your metal roof’s lifespan can include:

  • Roof Color: A darker roof tends to absorb more heat, while a lighter colored roof reflects heat. The heat absorption and UV exposure will eventually take a toll on your metal panels, degrading the material over time.
  • Roof Pitch: Pitch refers to the steepness of a roofing system. A low sloping roof speeds up wear and tear because it soaks up and weakens the roof material.
  • Installation: No matter how durable your metal roof is, it won’t last if it was poorly installed. Your roofing contractor must install the roof according to the manufacturer’s specifications. They should be a certified installer. Also, make sure that your contractor is licensed and provides labor and material warranties.
  • Maintenance: All roofing systems need care. Metal roofs put busy homeowners at an advantage because they’re low maintenance. But just because they’re low maintenance, doesn’t mean you don’t have to inspect it. Regular inspections by a licensed roofer ensure that it receives early repairs before problems get bigger.
