How Long Does A Metal Roof Last?

If you’ve been thinking about replacing your existing roof, you should consider getting a metal roof. I remember the aggravation my old shingles used to cause me, and I’ve been much happier since I switched over to a metal roof.


Metal roofs are gaining popularity across the United States with every passing day. They are durable and have a longer lifespan than other roofing materials, which I appreciate. Durability and longevity are not the only immense benefits that encourage more people to invest in metal roofs.

Imagine your old asphalt roof: its life span is just 20 years, and when the sun beats down on it constantly, it could start deteriorating even sooner than that. Wood shingles also get damaged rather quickly when exposed to various weather conditions. A metal roof, however, will protect you from any environmental conditions.

The major question most people want to know when they think about switching over to a metal roof is how long does a metal roof last? I will answer the question in detail in this article.

What Are The Advantages Of A Metal Roof?

Like everything else in the world, metal roofing also has some pros and cons. If you want to invest money in a metal roof, then as a buyer, you should know first about its advantages and then its downsides.

#1. Durable

Almost all metal roofs are durable. If you install them properly, they last as long as your house does.

#2. Resistant To Any Weather Conditions

Some areas in the United States are prone to excess snowfall or heavy rainfall and scorching sun in some months in a year. If you use wood shingles or any other roofing material, your roofs will be damaged quickly. But a metal roof can resist any harsh weather conditions.

#3. Fire-Resistant

If you are unfortunate enough to experience fire near your house and have wood shingles on your roof, it will easily catch fire. Metal roofs are non-combustible; therefore, they do not catch fire easily.

#4. Energy-Efficient

Metal roofs are energy-efficient, which means they reflect most of the sun’s rays, thereby helping keep your house cool and allowing your air conditioner to do less work. So, indirectly, the metal roofs are reducing your electricity bills. You can even install solar panels on some metal roofs, which will provide you with clean and green energy.

#5. Lightweight

Metal sheets usually weigh 0.88 lb per square foot, depending on the gauge, whereas other roofing materials such as asphalt weigh more than 5 lb per square foot.

#6.Easy Installation

Metal roofs are easy to install, and you can do it independently without the help of any roofing professional. You can even install the metal panels directly on your existing roof without having to tear your roof apart. Some may be curious regarding how to install metal roofing.

You only need to follow a few simple steps, like measuring the roof, selecting the metal panels, removing the old roof and placing your new metal roof. The last step is to correctly install the ridge cap because it prevents airflow inside your house. Ridgecaps are also helpful in shedding water from your roof.

#7. Increases The Resell Value Of Your House

If you have a metal roof that is in good condition and you want to sell your house, a buyer will be interested in your home. You will be able to sell your house at a great price with this added feature.

#8. Maintenance

Metal roof maintenance is relatively easy. You don’t have to do much to maintain your roof, but you do need to clean it within regular intervals. Repainting your metal roof every five to six years is also necessary.

#9. No Tenancy For Rodents

Rodents and other pests will not waste their time trying to break through your metal roof.

#10. Wide Variety Of Metal Panels

The buyer has numerous choices if he wants to install metal panels in his house. Many metal panels are available on the market, like aluminum metal panels, zinc metal panels, tin metal panels, standing seam panels and various others. Even the color differs from one panel to another. So you need to choose carefully.

#11. Recycle

Metal panels are not harmful to the environment, as old panels can be recycled.

What Are The Disadvantages Of Metal Roofs?

#1. Expensive

Metal roofs are a bit expensive. The price of the metal panel usually ranges between $150 to $600 per hundred square feet, which is relatively high compared to other roofing materials.

#2. Noisy

When the rain falls on the metal roofs during the rainy season, it can be rather noisy. You can reduce the noise to some extent by adding an insulation layer to your roof.

#3. High Chance For Accident When Wet

When wet, metal roof panels are quite slippery. So if you are up on your wet metal roof, falling is a real possibility. It’s best not to walk on metal panels during rain or when they are wet.

#4. Dents

There are different gauges of metal panels. If you use thin gauges like 29 -gauge metal panels on your roof and stay in a location where there is excess snowfall, then you will find dents on your metal roof within a short timespan. So, try to use thicker gauge material if you stay in an environment where there is excess snowfall.

As you can see, using metal roof panels on your roof has more benefits than drawbacks.

Different Types of Metal Roofs

There are many different types of metal roofing.

#1. Tin Metal Roofing

A tin metal roof looks greyish. Manufacturers are producing tin metal panels coated with steel to ensure a good life span and corrosion resistance. Tin roofs usually last for 60 years, but you need to perform maintenance from time to time.

#2. Steel Metal Roofing

Most people prefer to have steel metal panels on their houses because they are economical and durable. The manufacturers don’t use bare steel for metal roofs. They use a protective coating on the steel called galvanized steel.

Installation of metal roof

The galvanized steel contains zinc, and when we use these panels on our roof, they won’t rust easily. Another great protective covering on steel is galvalume which includes both aluminum and zinc. The galvalume is three times more corrosion resistant in comparison to galvanized steel but is a bit expensive.

#3. Aluminium Metal Roofing

The aluminum metal panels are lightweight and durable but don’t use these metal panels in the areas where there is frequent snowfall. The aluminum panels are light, so they will dent easily.

#4. Copper Metal Roofing

Copper metal roofing lasts for 200 years. Copper metal panels don’t need any coating, but they are costly. So, not everyone can afford copper metal roofing.

#5. Zinc Metal Roofing

Zinc roofing is durable and lasts for 100 years. The zinc roof panes don’t rust easily.

Factors Affecting Metal Roof Durability


Proper installation can increase the durability of a metal roof. Now the question comes how to install a metal roof. You can do it yourself if you follow some simple steps.

#2. Repainting

You should repaint your metal roofs from time to time. While repainting, you need to use good paint and primer to protect the metal panels and increase durability.

#3.Cutting Of Metal Panels

While installing the metal roof, you need to cut the metal panels wisely. There are many cutting tools available, like a circular saw, nibbler, power shear and tin snips. You can choose according to what best fits your needs. Now the question is how to cut metal roofing. Well, there are a few steps that you will need to follow to cut a metal panel precisely.

Cost of Metal Roofs

If you decide to change your roof and buy metal roof panels for your house, you must want to know how much a metal roof costs. The metal roof cost depends on various factors like the type of metal in the roof, shape and size, paint, primer, installation, labor costs and your roof’s complexity.

So, it’s pretty tricky for me to say the exact cost of a metal roof. You will need to spend approximately $850 – $1600 per square of your roof. Here one square refers to 100 square feet of your roof.

Now how much does a shingle roof cost? Well, the price of metal shingles usually ranges between $10.50 – $14, including installation charges per square foot of your roof. If you choose a standing seam metal panel for your roof, you need to spend $12 – $16 per square foot.

Cost Of Metal Roof Versus Shingle

Now we are going to compare the cost of a metal roof vs. a shingle. The cost of a metal roof versus an asphalt shingle or any other kind of shingles depends on your location. In my opinion, if you are going to choose asphalt shingles, then their durability will last only 12 – 20 years.

They will also need maintenance within very short intervals of time. If you opt for asphalt shingles, there may be a chance that you need to change your roof again not too long afterwards.

Metal roofs are far better than shingles but also more expensive. The national average cost of a metal roof is almost $18,500. A metal roof will cost you just $850 – $ 1600 per square foot, whereas the asphalt shingle will cost you $100 – $200 per square. Even the installation charge will be more for the metal in comparison to asphalt shingles.

If we talk about metal shingles and standing seam metal panels, then standing seam metal panels will be more expensive when compared to metal shingles. This is because the standing seam metal panels are pretty tricky to manufacture, fabricate and install.
