Pros & Cons of Metal Roofs

The time when metal roofs were first used can be traced back to the 1700s. Around this time, the main metals used for roofs were lead and copper. When the 18th century started, America developed the first facilities for rolling copper sheet metal. It was also in America where sheet iron was first produced. Meanwhile, corrugated iron was developed by the English. Since then, experimental practices for further development of metals to be used on roofs continued, and up until today, we continue to enjoy the years of hard work that different people dedicated themselves to when we choose to use metal roofs to protect our homes.


The experimentation done by foreign countries to improve metal roofs benefited many others including the Philippines. As you travel around our country, you’ll see many houses use metal roofs as using metal roofs have several advantages, but as with everything in this world, metal roofs have disadvantages too.


In this article, we’ll be talking about the pros and cons of using metal roofs.



The first and biggest benefit of using a metal roof is its durability. Metal roofs are extremely durable as long as they are properly installed and well maintained. It can stand against any weather conditions, which in our country’s case are heavy rain and extreme heat. It is also notable to mention that metal roofs are resistant to fire, in fact, they are rated class A which is the highest level in fire resistance level. So, if you’re looking for a material that will definitely last you a lifetime, a metal roof is the one to choose.


The second advantage of using a metal roof is that it won’t be blown away by the wind. When installing metal roofs, the metal panels are connected to one another, thus even a strong wind can’t blow them away compared to other roofing materials that are installed by overlapping one material on top of another thus depending on gravity to keep them in place. In a way, we can say that metal roofing is wind resistant, which is also a winning factor for people living in the Philippines as storms accompanied by strong winds frequent the archipelago.


The third advantage of using metal roofs is that they will last for a long time. When we compare the life expectancy of metal roofs to asphalts that were traditionally used, the difference is huge. Metal roofs last for 40 to 70 years, while asphalt roofs last for a maximum of 20 years. If you’re someone who plans on living in the same house your whole life, you can be confident that your metal roof will last the whole time of your stay.


The fourth advantage of metal roofs is that it helps homeowners save on their electricity bills. How is this so, you may ask? Metal roofs do this by reflecting the heat of the sun instead of absorbing it, thus you won’t have to spend extra on a cooling system. 


The fifth advantage of using metal roofs is that they are fully recyclable, so if you decide to change your roof, you won’t have to worry about its negative impact on the environment as metal roofs are considered to be eco-friendly.


As for the sixth and final advantage of metal roofs: they are very adaptive. The wide variety of designs can fit any type of houses, be it low and steep pitch roofs or rounded or arched ones.



As for the disadvantages of metal roofs, the first on our list is that installation of metal roofs is expensive as the process is more complicated than using asphalt for your roof. This is because metal roofs are carefully placed to meet the configuration of your roof, while asphalt relies on sealants, hence requiring a skilled worker who is specialized in the installment of metal roofs.

The second disadvantage of using a metal roof is that it can be noisy when different objects hit them, but the most common are raindrops. However, this is not entirely true as the echo of objects hitting on your roof can be minimized by installing your metal roof over solid decking. The solid decking will help absorb some of the noise made by your metal roof.


The final disadvantage of using metal roofs is that they can be difficult to access in case you want to check the condition of your roof. This is because metal roofs are hard to walk on especially if it’s been raining as they can get slippery. Moreover, if moss or algae grows on your metal roof, they will contribute to your metal roof being slippery, and that will make your cleaning job more difficult and dangerous.


Overall, the advantages of using a metal roof outweigh the disadvantages. Although the installation part may be a big negative factor, if you think about it, you’ll see how the price will be balanced out by the many advantages, but most especially the durability of metal roofs that will allow you to use them your whole life. With that, AllHome can say that a metal roof is a good investment.
