How long does a metal roof last? There are multiple factors that affect durability and longevity. Find out what makes them so durable.
In the market for a new roof for your home? After just a few minutes of searching, you’ll see that there are so many different options. Metal roofs are known for being popular right now, as they are known to be highly durable. What is it that makes these roofs so durable, and how long does a metal roof last?
How A Standing Seam Roof Works
Most metal roofs are standing seam roofs, so that’s what you will typically get with a new metal roof. These roofs are made with a series of panels that are locked together at the seams. Standing seam roofs are where they get their name from.
This is usually the preferred roofing method, as the roof panels can expand and contract freely when the weather heats up and cools down. There are no worries about cracks forming or other issues with the roof, as there is space for that movement.
There’s also the option to go with a screw-down metal panel roof, which is just what it sounds like. Panels are screwed down to the roof, with the fasteners exposed. These aren’t commonly used on homes, though, as they can’t expand and contract and have a shorter life span.
With a standing seam roof, you have many options when it comes to the look of them. You can choose from almost any color you want, and you can even get panels that mimic the look of other roofs. For example, they can be made to look like asphalt shingled or shake roofs.
On average, a metal standing seam roof will last around 40 – 70 years. This depends on the type of roof you have installed and how well you maintain it.
Why Are Metal Roofs More Durable?
That’s a long time for the roof to last, especially as asphalt shingle roofs will generally last around 15 – 30 years when they’re well cared for. What is it that makes them so hardy?
When a metal roof is installed, it is put on your roof in panels rather than individual shingles. As there are larger panels, there is less chance of a part of it cracking or breaking off as shingles can do. Because of this, you won’t see nearly as many leaks and other issues with your roof.
Plus, the metal itself is a sturdy material. When installed correctly, you’ll find that it can withstand high winds of up to 140 mph. That covers you for most storms, so you won’t need to worry about it being damaged that way. They are more impact resistant, too, depending on the metal you choose.
There’s also their resistance to fire that makes them more durable. Metal roofs are naturally resistant to flames and sparks, so you don’t have to worry about them catching fire during a lightning storm or wildfire. Metal roofs have the best fire resistance rating possible.
Factors That Affect Durability
While a metal roof will be durable overall, some factors will affect how durable it is. Here’s what you need to look out for:
The finish of the roof:
Most good, modern metal roofs will have a finish on them, designed to help them last longer. This protects the metal underneath from moisture, which can cause it to rust. When having a roof installed, check to see what kind of finish is on the roofing panels. You will also notice that some finishes come with warranties for as long as 30 years. To ensure that the finish does its job correctly, you need to ensure that it isn’t scratched or nicked during installation. If that should happen, it can mean that the roof’s lifespan can be reduced.
The weather conditions where you live:
Where you live will have an impact on your roof’s lifespan. While metal roofs can take a lot, there will always be wear and tear. The severity of the weather in your area will determine how soon the wear and tear affect the roof itself. For example, snow will wear off a finish over time, and extreme heat can affect the shape of the panels. Talk to a roofer before you have yours installed, so you know the risks.
Regular maintenance:
No matter what kind of roof you have, you should always perform routine maintenance. If you ignore your roof’s needs, then you’ll end up with surprise repair bills. You’ll want to check things like the vents and gas pipes to ensure no leaks or other issues will affect your roof.
Metal vs. Asphalt Roofs
You’ve seen the benefits of metal roofs, but what makes them a better option than a traditional shingle roof? Here are a few ways they can benefit you:
Longer lifespan:
As mentioned earlier, a metal roof can last up to 70 years, while an asphalt roof can last up to 30. If you want something that will last a long time, metal is the better choice here. It’s significantly better if you aren’t planning on moving home any time soon.
Less leakage risk:
There aren’t as many entry points for water in a metal roof as there are in an asphalt one. If a shingle warps, cracks or breaks, then water can get in. With larger metal panels, this is much less likely to happen.
Less maintenance needed:
You’ll always have to do some maintenance on your roof to keep it in good condition. However, metal roofs need much less than asphalt ones. That saves you a lot of time and effort over the years.
Fewer repairs needed:
After a routine check, you may find that your roof’s shingles have come off and need replacing. There’s also flashing that may need replacing. There’s much less to it on a metal roof in terms of parts, so they require fewer repairs too.
Metal roofs offer you a lot of benefits that you can’t get with other roofs. Look into getting one for your home, and see just how much they can protect it from the elements. Now that you know the question of “how long does a metal roof last?” you know what to look for in your next roof.
