How Long Do Metal Roofs Last?

Metal roofing can last a long, long time. While the exact lifespan of your roof will depend on the metal it is made of and how it was installed, these roofs generally last longer than other commercial roofing in Denver.

Metal Roofing vs. Traditional Roofs

Most metal flat roofs are warrantied for 40 years, which is significantly longer than the warranty of any other type of roofing on the market. On top of that, the Metal Construction Association has found that many metal roofs last for at least 60 years before they need to be replaced.

Comparatively, the average lifespan for asphalt shingle roofs is 23 years and single-ply roofs come in at 20 years.

As if that wasn’t enough, metal roofs are cheaper, too. Ducker Research Company found that metal roofs have an average lifecycle cost of 30 cents per square foot. Asphalt roofs cost 37 cents per square foot and single-ply roofs cost 57 cents per square foot!

When the math is all finished, metal roofing costs 3.5% of the total installed cost. Asphalt comes in at 38.5% and single-ply at 19%. Clearly, metal roofing will not only last, but it will save you money, too!

Why Does Metal Last So Long?

There are several reasons why a metal flat roof lasts so long.

  • Metal is strong! It can resist the elements, so things like high winds and snows won’t mean it needs to be replaced. It’s even more impact resistant than other commercial roofing materials, so hail won’t necessarily necessitate replacement.
  • Metal is fire resistant. Even a lightning bolt won’t ignite it.
  • Metal roofs have roof clips. These allow the roof to shift and move, both with repeated freezing and thawing patterns and with any seismic activity. It can shift as needed without concern for the roof’s integrity.
  • No pests eat metal roofing.

Metal roofing even does good when you finally do have to replace the roof. You can recycle it so that nothing is wasted.
