Metal is a sustainable material that contains a high portion of already recycled material. If your metal roof one day needs to be replaced, the panels and other roofing components can be melted down and used to create other metal roofs. Asphalt shingles by comparison would merely be tossed into a landfill if they ever became damaged or needed to be replaced.
Due to the extended longevity of your roof, you wont find yourself replacing it every few years, which mitigates the use of fuel and heavy equipment. Everyone wins in the end. The metal roofing company gets the job for the installation, you as the homeowner get long-lasting protection from the elements, and the environment gets the protection it needs for a win-win-win situation.
One of the most common reasons a metal roof has issues prematurely is due to errors made during the installation. Many times the mistakes are simple, such as not tightening screws properly or using the wrong sealant.
It is crucial to hire a roofing professional that has specialized experience with installing metal roof panels and has a valid contractors license. Depending on the type of panel used, metal roof installations require a different set of skills and tools than other types of roofing installations.
An installation that is done properly gives your roof the best chance of lasting as long as possible.

How Long Does A Zinc Roof Last
Some say zinc roofs can last for centuries, and this isnt an unfounded claim.
Zinc roofs develop a patina, but their patina is different from copper roofs.
Generally, saying these roofs last for 100 years is a safe bet.
Zinc patinas are layers of hydroxyl carbonate, which is a self-healing material that reforms itself over time.
When a zinc roof gets scratched, the patina will cover the damage as if it never happened.
This phenomenon has led to the option of buying pre-patinated panels, though you can always purchase new zinc.
Some homeowners like to collect rainwater, but other materials can contaminate the fluid, making it unsafe to drink.
Zinc is different, as the water is tested and found free of harmful chemicals from the roof. Its still necessary to filter and boil the water for safety.
It takes less energy to make zinc roofing than steel or aluminum, as the metal has a lower melting point.
Therefore, zinc has less of an impact on the environment.
Disadvantages Of A Metal Roof

âCost: Metal roofs may be worth the cost because of how long they last, but they do cost a lot more than asphalt roofs.

The pooling water encourages premature corrosion on almost all metal roof materials. Ensure you clear out the drains and gutters at least once per year.

How Long Does A Copper Roof Last
Copper roofs are one of the two materials that can easily last more than 100 years.
Copper roofs that are just installed glow brightly under the sun, but as with all copper objects, they undergo patination. This process might not be pleasant to antique collectors, but its a desired trait on roofs.
The patina the copper roofs develop can range from a darker green to a near turquoise shade, and this process only requires time.
The golden glow will slowly be replaced with a beautiful layer that doesnt need to be maintained. Few people would paint or coat a copper roof.
Patinas are also a layer of protection against the elements and will only keep growing.
Its known that patination can keep copper objects intact for more than a thousand years, even though roofs might not be that hardy.
Repairing copper roofs isnt too difficult, as it consists of soldering pieces as replacements. It barely needs maintenance anyway.
Most copper roofs are made of recycled copper, which is great for the environment.
If youre environmentally conscious, this material and zinc are excellent choices.
However, a copper roof is indeed an expensive upfront product.
Its a worthy investment, though not everyone can afford one.

While there are several factors that impact how long your roof lasts, your roof’s lifespan most heavily depends on the materials used. Let’s take a closer look at the various roof types and how long each of them lasts.
Picking The Correct Metal Panel Gauge
A panels metal gauge, or thickness, can influence its durability, which in turn influences its life span. Keep in mind that the lower the metal gauge number, the thicker the metal. The thickness of a 24-gauge metal panel is greater than that of a 29-gauge metal panel.
As a result, a 24-gauge panel would be more durable than a 29-gauge panel.
A thinner material could be a problem when it comes to harsh weather elements like snow, high winds, or hail. I would not recommend 29-gauge if you live in an area where there is regular snowfall. There might be leaks if there is excessive snow.
Homeowners who live in the high-wind zones should avoid thinner metal. A 24-gauge roof is thicker and heavier than a 29-gauge roof. The more the weight is, the more chance there is of resistance during more adverse situations.
