It’s no doubt that a metal roof provides sound protection and durability for residential, commercial, and industrial buildings. But, just how long should a metal roof last? Well, with proper installation and little maintenance, a metal roof can last more than 40 years. In fact, zinc and copper roofs can last more than 100 years.
When you compare metal roofing with typical asphalt shingles, you realize that metal roofing is way better in terms of durability. Asphalt shingle roofing requires replacement after every 12 to 17 years. This combined with other benefits of metal roof makes it a popular roofing option for modern buildings.
Metal Roof has a Low Lifecycle Cost
When it comes to performance, both metal shingles and standing seam roofs do not have a difference. High-end metal roofs like standing seam and metal tiles or shingles are basically a lifetime system. Essentially, once you ensure proper installation of your metal roof, you won’t have to install or replace the roof again.
What’s more, the exceptional longevity and durability of a metal roof gives it a low life-cycle cost. This implies that though you will spend a significant upfront cost on metal roof installation, you will save money in the long run. That’s because your metal roof will most likely not need replacement or repair.
Most manufacturers of metal roofs provide a warranty of 30 to 50 years. Metal roof installers provide their installation warranty too. That means you are not likely to spend a significant amount of money on your metal roof after installation.
Durability of a Metal Roof
There are several reasons why a metal roof lasts longer than other types of roofs.
- A metal roof does not split, rot, dry out, warp, chip, leak, or crack like other roofing materials.
- Metal roofing is not damaged by rodents or termites
- Metal roofing can withstand the effect of falling objects like sticks and hail without sustaining damage.
Generally, a metal roof will last long with little or no maintenance. Ideally, you just need water to clean your metal roof. Corrugated metal roofs may require retightening of the exposed fasteners every 10 to 15 years. You can opt to repaint your metal roof after serving you for years just to refresh its look. However, this is not a must and it depends on the original coating of your metal roof.
Common Problems that Affect the Lifespan of a Metal Roof
It’s important to understand the most common problems that affect the lifespan of a metal roof.
Major among them include:
- Loose fasteners and seams
Temperature variations cause contraction and expansion of metal. This can loosen fasteners and seams leading to leaks on a metal roof. Other problems that can affect a metal roof include corrosion and rust. These are caused by the accumulation of debris and decaying materials combined with ponding water.
If you live in a coastal region, you need to be vigilant in maintaining your metal roofing system. That’s because salty air can particularly be hash on your metal roof. What’s more, though a metal roof is capable of withstanding storms better than other types of roofs, it can be damaged by excessive hail, precipitation, and high winds.
Metal Roof Provides Excellent Money Value
Generally, a metal roof has an extended lifespan when compared to other roof types. Galvalumed and corrugated galvanized steel can last for at least 50 years. Their aluminum variant has a lifespan of more than 70 years with proper, regular maintenance.
Standing seam galvalumed and galvanized steel can last more than 70 years with proper maintenance. Additionally, their aluminum variants can even outgrow the homeowner’s lifespan.
Overall, a metal roof provides an excellent money value. It is a cooler roofing option with excellent aesthetics and long-term durability. The elastomeric paint coat of a metal roof provides weathering protection and rust-proofing. So, if you are looking for a roof that provides the best value for the money spent on it, go for a metal roof.
The most amazing thing about a metal roof is that it lasts long while requiring minimal repairs. However, regular metal roof inspection is required to ensure that the roofing structure is in proper condition. It’s only through roof inspection that minor problems can be spotted and fixed before they smolder into major repairs.
After installation, a metal roof can show fading and wear signs as its warranty nears the end. Instead of tearing the entire metal roof or replacing it, minor repairs can be done and a fresh coating reapplied. A new coating can extend your metal roof’s life with several years.
