How Long Will Metal Roofing Last?

When replacing your roof, one of the most important decisions is choosing the roofing material you will use. Several factors will impact that decision, but one of the big ones will be how long the new roof will likely last. Installing a new roof is one of the most significant financial investments you will make into your home, so it is not something you want to have to do multiple times! As a metal roofer in Knoxville, we recommend metal roofing if you are looking for longevity at an affordable rate.

When your metal roof is installed correctly by a professional metal roofer in Knoxville, it should last 50 years or more, assuming it is properly maintained. Let's take a closer look at some factors that can impact the lifespan of metal roofing.


Metal roofing is very attractive for many homeowners because it requires little to no maintenance when properly installed by a metal roofer in Knoxville. A visual inspection a couple of times a year is usually sufficient for metal roofing to ensure no damage has occurred. However, clearing off any debris collected on the roof, such as leaves or branches, can be beneficial as a preventative measure to protect your roof.


Like any other roofing system, metal roofs are only as good as their installation, which impacts how long your roof will last. Having your metal roofing installed by an experienced metal roofer in Knoxville is essential. This will ensure everything is installed appropriately, minimizing the risk of leaks or cracks. Professional installation can substantially extend the lifespan of a metal roof.


All exterior materials of your home play a key role in protecting your home and family from the elements, and metal roofing is no different. Metal roofing is generally very functional in all climates. However, occasionally, there can be issues due to 'thermal shock,' which is caused by the metal contracting and expanding rapidly in extreme temperature shifts. This can result in gaps in seams or cracks on panels. In Tennessee, the risk of thermal shock is most prevalent in Winter, but it is not exclusive to metal roofing and would be a factor for any roofing. Metal roofing withstands extreme temperatures much better than many other roofing materials, so it is an excellent choice if thermal shock is something that you have concerns about.

What Makes Metal Roofing Last So Long?

So, what is it about metal roofing that makes them last for 50 to 70 years when well maintained and properly installed by an experienced metal roofer in Knoxville? Let's look at some of the characteristics that help with this longevity.

  • Sturdy Construction - Metal roofing isn't just any random sheets of metal! The materials used have been developed over years of research and include high-performance materials to make them as strong and durable as possible.
  • Lightweight - Some roofing material is quite heavy, putting a strain on the structural integrity of the building. In comparison, metal roofing is designed to be lightweight, making it more durable while also putting less strain on the structure. This makes metal roofing an option for most properties, even older historic structures.
  • Resistant to Fire, Rot & Pests - Many homeowners approach a metal roofer in Knoxville to discuss their roof because they have heard that metal roofs are resistant to just about every threat! Metal is not combustible, making it fire resistant. However, it is also resistant to rot, insect damage, moss, and fungus. This reduces the maintenance needed and extends the roof's lifespan.
  • Energy Efficiency - Metal roofing will reflect the heat from the sun making your property cooler in Summer and warmer in Winter. This can positively impact your heating and cooling costs in the form of lower utility bills. According to studies, metal roofs can save up to 40% on energy costs.

Is Metal Roofing Worth the Price?

If you have been shopping around for roofing, metal is a little more expensive than other materials. However, it is essential to consider other factors when determining the value for money. If you discuss your options with a metal roofer in Knoxville, they can explain that although metal roofing may cost a little more upfront, it will last longer and likely require far less maintenance than some of the cheaper options. This means that over time, it works out better value. You may need to replace another type of roof long before a metal one reaches the end of its lifetime.
