Installing or replacing a metal roof can cost anywhere between $5,500 and $15,200, making any roofing project a significant investment for any homeowner. So, it is only reasonable to wonder how long your new metal roof will last.
Luckily, metal roofs are not just cost-effective, excellent insulators, and highly versatile - they are also extremely long-lasting and able to stand the harshest weather conditions! However, your home’s metal roof represents the ultimate barrier against the elements, and, over time, it can start showing signs of wear and tear.
Learn about the average lifespan of a metal roof, how to extend it, and how to know when it’s time for a roof repair or replacement in this JML Sheet Metal guide.
How Long Will Your Metal Roof Last?
Whether you are looking to invest in a new roof or wonder about the lifespan of your existing one, you will be happy to know that metal roofs are the longest-lasting types on the market. The lifespan of your metal roof will depend on the type of metal you have chosen for it and how well the installation process is performed. However, on average, homeowners tend to replace a metal roof after over 50 years!
While asphalt materials that are traditionally used need replacement after 12-20 years, with proper care and maintenance, your metal roof can last for as long as 70 years - or 100 in the case of zinc or copper roofs!
What Affects the Durability of Your Metal Roof?
As we have seen, metal roofs are extremely long-lasting, and they will protect your home without much care or maintenance for over five decades. However, don’t forget that your metal roof is always on the line of fire of natural elements!
So, it is important to understand what elements affect the integrity of your metal roof and avoid having to replace it before the end of its lifespan. Here is what can shorten a metal roof’s life:
- The type of metal you have chosen - from steel to aluminum and copper, the roof material you choose, as well as how the metal has been fabricated, will affect the metal roof’s lifespan.
- Quality of installation - metal roof installation should be performed by an expert contractor to increase the roof’s lifespan and guarantee its integrity.
- Natural elements - some metals will rust when exposed to moisture, snow, sleet, or humidity. UV rays, sun, and heat exposure can also corrode the metal.
- Scratches - scratches and cracks on the metal roof’s paint can make it easier for water and moisture to penetrate and cause the metal to rust.
Tips To Increase the Life of Your Metal Roof
Installing or repairing a metal roof is a long-term investment that is not just great for the environment and your home - but also for your wallet! Studies have shown that metal roofs can reduce energy costs by 40% and improve your whole home’s insulation. However, to protect your investment, there are some tips that can help you increase its lifespan:
- Make sure surrounding trees don’t scratch the roof, which can facilitate rusting
- Don’t let debris, foliage, and other objects rest on the roof
- Don’t walk on your metal roof
- Keep your gutters clean to prevent water damage, leaks, and winter issues such as ice dams
- Invest in professional roof inspections and assess your roof integrity twice a year
If in doubt, a roof professional can help you better understand how to take care of your roof and extend its lifespan - and can tell you if your roof needs repairing or replacing!
