How Long Will My Metal Building Last?

how long will my metal building last?

A tricky question. Metal buildings will require maintenance, so they’re not a maintenance-free option by any means. With this in mind, steel buildings are also susceptible to the elements, albeit they are much less vulnerable than a traditional building.

A lot of metal buildings have a 50-year warranty, so this is a good starting point.

Roofing and siding will be the main point of failure, but a little maintenance can go a long way in ensuring that your building reaches the 50+ year mark.

There are stories of 70+ year metal buildings still maintaining their integrity with little maintenance needed. Of course, if you live in an area where natural disasters occur, the building may fail, depending on the severity of the issue.

Homeowners that want to use their metal building as a garage will find that a 30×40 metal building provides more than ample space for a garage. You might even be able to use space for storage or even set up your own little workout studio in your garage.

Dimensions for a typical garage are:

  • 12 x 22 (a one-car garage)
  • 14 x 22 (longer vehicle option)
  • 16 x 24 (long truck storage)

As you can see, you’re able to fit two longer vehicles in your building with 18 feet of space available. You can use this space for smaller vehicles, or you can make use of the additional 480 space for tools to work on your cars.

And the 480 square feet is if you have a truck. You can have as much as 600 additional square feet of space to build a workshop in your garage. It’s more than enough room for all of your needs.

  • Crafts
  • Woodworking

  • Auto repair

  • Repair shops

  • Real estate offices
  • Insurance offices

You’ll find that even fast food restaurants use somewhere in the vicinity of 1,200 square foot buildings. Metal buildings have the benefit of not being combustible, so if a fire does break out, it will remain contained, which is a big benefit for businesses and their customers.


Metal buildings are a mainstay in the agricultural industry. These buildings have many uses in agriculture, including:

  • Storage for equipment, hay, feed and so on.
  • Small barn structures.

Storage is the main choice for these buildings in the agriculture industry, so you’ll find that many farms choose to use their building to store items that otherwise don’t have a “home.”

Since metal is weather-resilient, farmers don’t have to worry about their grain, feed or equipment being damaged by the elements. In the event of an outdoor fire, the building will hold up much better than its wooden counterparts.
