Metal roofs can last between 40 and 70 years, depending on the material. Traditional asphalt roofing materials have an estimated life expectancy of approximately 12-20 years. The average metal roof will last between 40 and 70 years. Some materials, such as copper roofs, will last even longer with some copper roofs that date back more than 100 years.
There are also a number of factors that can increase the longevity of your roof, as well as decrease it. Did you know that some steel roofs installed in the 20th century have not yet been replaced? That's how durable steel roofs are. In fact, if we compare steel roofs to asphalt shingles, steel roofs can last longer without the need for major repairs. As you can see, they are a smart long-term investment.
This is a copper roof that dates back to the 18th century. This greenish color is called patina, a protective coating that develops as the copper roof ages. How long does a metal roof last if it's made of copper? It should be expected to last at least 50 years. Over time, copper roofs develop a patina that indicates corrosion.
But this blue-green coating is really protective in a way that further waterproofs the roof. While metal roofs cost more upfront, this cost is offset by their longer life expectancy and durability. Metal roofs can last 60 years or more, and require little or no maintenance. Many roof suppliers offer a 50-year warranty for metal roofing because they can withstand the elements and are resistant to mold, mildew, and insects.
Metal roofs have a life expectancy of between 50 and 70 years and are very versatile. In metals such as copper, durability extends to more than 200 years. Pure metals are coated with metallic elements to form alloys that make them last longer. It is a design where metal roofs are built to help guide rainwater and prevent water and ice from accumulating and seeping into the house.
However, the appearance of metal roofs may not be to the liking of many homeowners, which could also affect resale value. Metal roofing isn't the only durable option for homeowners when it comes to protecting their families from the elements. Depending on the type of paint used on steel or aluminum panels, it will be determined what type of guarantee you will get on a bolted metal roof system. While it depends on the type of tile roof you choose, on average, tile roofs need to be replaced about two or three times in a 60-year period.
As mentioned above, metal roofs are very versatile and have a life expectancy of between 50 and 70 years. Thanks to the durability and high energy efficiency of metal roofs, homeowners are likely to see a better return on investment compared to tile roofs. A properly installed metal roof will typically last as long as the home, with an expected lifespan of 40 to 70 years and often a 30 to 50 year manufacturer's warranty to boot. When metal is strong, it will last longer and copper is known to be one of the most durable roofing materials available.
In addition, some metal roofs are coated with special reflective pigments to minimize heat gain and keep occupants comfortable without having to start the air conditioner. But to get the maximum benefit, it is better to install a metal roof in the house that you plan to inhabit for a long time. As long as it's properly installed and your attic is properly ventilated, there's no reason you can't get at least 30 years off your standing seam metal roof.
