How long will a metal roof last? 

When most people ask, “How long will a metal roof last?” they are trying to understand the value of metal roofing and are interested in it or interested in learning a little more about it. At Tri County Metals, we think it’s a valid question, with several different and relevant answers.

How long a metal roof will last often depends on the make-up of the metal roofing panel.

The longevity of a metal roof is largely determined by what it is comprised of, so when we think about answering the question of how long will a metal roof last, we firstly have to consider what material the metal panel is made of. Tri County Metals prefers Galvalume® (a patented coating originally owned by the Bethlehem Steel company, now owned by BIEC International Inc, consisting of 55% Aluminum and 45% Zinc) for our base substrate, either as mill-finish or if we have it painted. The Galvalume® warranty is 25 years whether you use mill finish or prefer one of our 40 plus colors painted over Galvalume®. Many Galvalume® roofs out in the market today are well over 40 years old, so we think you can expect 40 to 50 years as a fair assessment. What material would you like to use, Mill finish or Painted?

How long a metal roof will last can depend on the paint system used to coat the metal roofing panel. 

As you explore the topic of how long will a metal roof last, it’s important to point out that our painted products are coated with Sherwin-Williams Industrial Cool Roof paint systems. All indicators are a painted metal roof can last well over 50 years. We believe this is a good and fair expectation for a metal roof. The warranties are for 35, 40 or even as many as 45 years for our “Platinum 45” extended warranty following certain roof applications guidelines.
