When we talk about how long a metal roof will last on a building, there are various things to consider in order to understand the overall lifespan. However, you can generally expect your metal roof to last anywhere from 40 to 70+ years with proper installation and maintenance.
At McClellands Contracting and Roofing, LLC, we often tell our Pittsburgh property owners that their metal roof investment could be the last roof they'll ever need to install. The life expectancy of a metal roof far exceeds traditional roofing materials like asphalt shingles, which generally need replacement after 15 to 25 years.
In this article, we will discuss the lifespan of a metal roof in order to help you prepare for your roofing project. If you are looking for professional-level metal roof installation in Pittsburgh and the surrounding areas of Pennsylvania, feel free to call us today at (412) 353-5660.
How To Calculate The Lifespan Of A Metal Roof
To determine how long your metal roofs will last, you need to keep certain important things in mind. Here’s a quick overview of these factors.
#1 Type of Metal Used
Different metal roofing materials have different lifespans which is important to be knowledgeable of to estimate the lifespan of your desired metal roof.
The table below provides a quick overview of the lifespan of different types of metal roofing materials.
| Material | Lifespan |
| Aluminum | 40 to 60 years with excellent corrosion resistance. |
| Steel | 30 to 50 years depending on the coating quality |
| Copper | 50 to 100 years, often lasting over a century |
| Zinc | 50 to 100 years with minimal maintenance |
#2 Installation Quality
You will also need to decide if you want to hire professionals for the installation. Choosing professionals based on price without checking their level of experience and expertise might save you a few dollars, but it comes with the risk of installation mistakes.
These installation mistakes can lead to early failures and significantly reduce your metal roof's life expectancy. As experienced Pittsburgh roofing contractors, we assure you that every part of your roof will be installed correctly; from the underlayment to the flashing details.
#3 Local Weather Conditions
Pennsylvania's seasonal weather has a large role in the ability of a metal roof to be durable. Heavy snow, rain, and temperature fluctuations all play an important role in determining how long your metal roof will last.
Luckily, metal roofs are designed to resist all these challenges when properly installed and maintained.
How Do You Maintain The Lifespan Of A Metal Roof?
Your metal roof's life expectancy largely depends on how well you maintain it. Here are some useful maintenance practices that can help with maintaining your metal roof’s lifespan:
#1 Regular Inspections
We recommend inspecting your metal roof at least once or twice a year, generally in the fall and winter.
During these inspections, look for loose or damaged panels, signs of rust or corrosion, damaged flashing around chimneys and vents, loose or missing fasteners, and sealant deterioration.
#2 Keep It Clean
Maintaining the life of your metal roof includes regular cleaning. Make sure that you regularly remove leaves, branches, and debris that’s collected on the roof.
Clear out gutters and downspouts properly to prevent water backup and wash off dirt or mildew accumulation. In regions with snowy winters like Pennsylvania, it is important to remove snow buildup regularly during the winter.
#3 Tackle Issues Quickly
Take quick action when you spot any small form of damage on your building's metal roof. Instantly responding to minor damage can help prevent expensive repairs and early roof failures.
Fix loose fasteners immediately, replace damaged sealants, repair any scratches or minor damage to prevent rust, and address any leaks as soon as you detect them.
What Are The Signs Your Metal Roof Needs A Replacement?
It’s also important to note the signs that directly indicate it's time for a roof replacement for your home. It is important to know these signs in order to avoid any sudden roof failure.
#1 Age-Related Signs
If you notice multiple panels are showing signs of water damage, and you repeatedly find yourself considering repairs for your existing roof, this is a sign that your roof is reaching the end of its lifespan. At this point, plans should be made to replace the roof.
#2 Damage-Related Signs
There are some forms of damage that can develop with exposure to harsh weather conditions and the lack of maintenance. So, it is better to notice these signs than to deal with sudden roof corrosion.
Check if your roofs have any widespread rust or corrosion, multiple leaks in different areas, structural damage from severe weather, or panels that are loose, buckling, or separating.
It is better to schedule a professional roof inspection at least twice a year as they can provide you with an accurate assessment of the situation of your roof and assist you in making the right choice.
