Lifespan of a Metal Roof – A Complete Guide
The lifespan of a metal roof is anywhere from 40 to 70 years or more. Some types of metals, such as copper and zinc, can last upwards of 100 years.
Their durability comes from quality materials that are properly installed and include essential protective coatings. When compared with other roofing options, such as shingles or tiles, a metal roof is the superior option with maximum protection, longevity, and minimal maintenance.
Having a roof you can depend on is essential, and so is knowing when it is time to replace it. However, doing so can be a major (and expensive) home improvement project. Is it possible that replacing your roof could be one of those things you’d do once and never have to worry about again? Perhaps, if you choose the right roofing.
Metal roofing is a durable, long-lasting solution that can provide you with peace of mind for many years to come. Here is your complete guide to the lifespan of a metal roof.
What’s the average lifespan of a metal roof?
Metal roofs may have a reputation for longevity, but what does that really mean? They last longer than any other traditional roofing material and can provide you with coverage for about 40 to 70 years, even longer.
It is important to note that the type of metal used will impact the lifespan, as each metal comes with different qualities. For instance, a steel roof can last 40 to 70 years, whereas an aluminum roof lasts 40 to 50 years, on average. Copper and zinc can last nearly 100 years or more!
Why Do Metal Roofs Last So Long?
There is no denying that metal roofs are durable and yield a long life. But what is it that makes the lifespan of a metal roof so long?
The Metal Itself
Metal is hardy and strong. And after being constantly exposed to the outdoor elements, it will not crack, shrink, warp, or erode. It can handle the strongest of weather conditions, such as heavy rain or snow, high winds, hail, and intense heat from the sun, without being harmed or compromised. It is also non-combustible, giving it a high fire rating.
Design and Install
It isn’t just the metal, but the way it is used that helps extend its lifespan. Standing seam metal roofs, for instance, conceal fasteners and interlocking panels to keep water from infiltrating. Utilizing proper flashing, ventilation, and underlayment also aids in leaving you with a durable, long-lasting roofing solution.
Protective Coatings
A metal surface is perfect for protective coatings to adhere to and offer an extra layer of security. Depending on where you live and the roofing company you work with, you may find that your metal roof is coated with a special finish to enhance corrosion resistance or be a moisture barrier.
You can also invest in these protective coatings as you see fit to protect your home.
Minimal Maintenance
Metal roofs require very little maintenance, making it easier to extend the life of your roof because there is less to get involved with. Regular inspections by roofing experts and occasional cleaning are all that is needed to keep a metal roof in optimal condition.
Factors That Impact The Lifespan of a Metal Roof
Not all metal roofs are created equal. There are certain factors that have an influence on just how long you can expect solid protection from your roof, such as the installation quality, maintenance, and local climate.
Let’s take a closer look at the factors that impact the lifespan of a metal roof:
The Quality of the Metal
Having a roof made of metal that is of higher quality is always beneficial. The grade and gauge (or thickness) of the metal, as well as any coating used, can be used to determine its ability to stand strong over the test of time. The better the metal, the better the protection and the longer the lifespan.
The Quality of the Installation and Maintenance
It doesn’t matter how great your metal is if it is not installed properly. Working with a trusted team of roofing experts, like Piedmont Roofing, can ensure that your roof is installed with proper flashing, ventilation, fastening, and more.
Routine inspections every 6 to 12 months and after extreme weather are necessary. Any issues that arise can be addressed promptly, increasing the life of your roof.
Environmental Conditions
The region where you reside can also play a role in how long your roof may last. Extreme temperatures and weather conditions, as well as exposure to high humidity and salt in coastal areas, may put a lot of pressure on the metal. While it can stand up to them, investing in routine inspections and protective coatings can help.
Metal Roof Lifespan vs. Other Roof Materials
If you are in the market for a new roof, you’ve got options. Asphalt shingles, wood shingles, clay tiles, and slate are all commonly used. So why choose metal? How does it compare to what the others have to offer?
Shingles can last about 15 to 30 years with extra care and maintenance. Clay tiles and slate, however, can last much longer—50 to 100 years. Unfortunately, they both require quite a bit of maintenance.
Metal roofs can last 40 to 70 years or more with very low maintenance. You can always feel confident in its durability.
