How Long Do Metal Roofs Last?

Updated: May 23, 2023

Metal roofs are a popular commercial roofing choice; known for their durability and low maintenance, they can easily outlast other roofing materials. We often get the question, “How long do metal roofs last?” We will give you the low-down on metal roofs in this blog.

How Long Do Metal Roofs Last?

The lifespan of metal roofs can be impressive. On average, metal roofs can last from 40-70 years. Compare this to the average lifespan of asphalt shingles which ranges from 15-30 years, and you can see why metal roofs are a popular choice. Asphalt shingles can be compromised by environmental factors and, at the end of their life, can be prone to buckle and warp. Metal’s durability makes it a popular commercial roofing choice.

What Can Affect the Lifespan of Metal Roofing?

With proper maintenance, metal roofs can meet and often exceed the 40-70 year lifetime average. Certain conditions can affect the longevity of a metal roof; being aware of these conditions and taking a proactive approach to maintenance can prolong a metal roof.


Climate - Metal roofs can withstand all types of inclement weather. However, the climate can impact the lifespan of a metal roof. Humid and overly wet climates can cause more wear and tear than dry climates. Areas prone to excessively high winds can cause natural wear and tear on a metal roof. Choosing the correct type of metal panel for your climate is critical to the longevity of a metal roof. Your United Materials project manager can assist you in choosing the best type of metal for your roof.


Proper Installation - Faulty or poorly installed metal roofs are more prone to leaks and cracks. This can reduce the lifespan of a metal roof. Ensuring your roof is installed by a professional with excellent references will ensure your roof lasts. This point of advice applies to any roof, not just metal roofs. Professional and warrantied commercial roof installation makes a difference. At United Materials, we have been installing roofs for 100 years, and we can provide excellent commercial roofing references.


Maintenance - Metal roofing is a popular choice due to its low maintenance. Asphalt tile roofs often need tile repair and replacement within 1-5 years. With regular inspections, metal roofs rarely need repair.


Benefits of a Metal Roof

Besides the long lifespan of a metal roof, metal also provides various other benefits when it comes to protecting your building.


Durable - When asked why a metal roof lasts so long compared to other roofing materials, the main reason is due to the durability of metal. Metal can withstand heavy winds, torrential rainfall, and heavy snowfall.


Pest Proof - Metal is a pest deterrent. Avoiding pest damage increases the longevity of a roof and protects the attic and heating/HVAC systems.


Total System - Metal roofs are not just sheets of metal slapped on roof frames. A metal roof is a total system and can be comprised of fasteners, underlayment, sealant, trim, and closures. High-quality components are crucial to the longevity of a total roof system.
