How long does a roof last?
If you’re like most homeowners, you’ve probably never had to worry about replacing your roof before. When the time rolls around and you have to choose a new roofing material, you may not know what the best option is for your home.
That’s why we’ve put together this list to show you how long different types of roofing materials last so you can install the best choice.
So let’s get started!
How Long Does a Roof Last?
There’s no one-size-fits-all answer to this question. The exact lifespan of your roof depends on a number of factors, such as the material, the weather conditions in your area, how well you maintain it, etc.
On average, you can expect your roof to last at least 20 to 25 years, but many roofs last much longer. Here’s a closer look at different roofing materials and how long they last.
Shingles
Shingles are the most common type of roofing material, but there are several different kinds of shingles, which include:
- Asphalt
Asphalt shingles are both durable and affordable, making them a popular choice for many homeowners. Since they can withstand almost any type of weather, they can last up to 30 years.
- Architectural
Architectural shingles are three times thicker than asphalt shingles, which make them even more durable. This extra thickness does make the price go up, but the added cost also improves the appearance. For example, homeowners can choose architectural shingles that look like they’re made of wood, slate, or tile.
these shingles last 25 to 30 years.
- Wood
Wood shingles also last about 30 years, but they require much more maintenance. Since they’re made of wood, they’re prone to warping or even rotting. If you don’t take care of these shingles properly, you may find yourself replacing them long before the 30-year mark.
Metal
Metal roofing is one of the strongest and most durable options out there. Its tough surface helps it withstand extreme weather conditions, and it also prevents snow from piling on (and possibly damaging) the roof structure.
Most metal roofs can last up to 70 years. However, some metals, such as titanium or zinc, can last 100 years or more.
Clay or Concrete Tiles
This type of roofing material is durable and low maintenance. In other words, you won’t have to do much to make it last a long time. These tiles can last over 50 years, but they’re heavy. So you’ll need a specially designed roof frame that can hold the extra weight.
Slate
Slate is a pricey option, but once you install it, you might not have to worry about replacing it again in your lifetime. The durability of slate roofs allows them to last about 100 years.
However, like clay or concrete tiles, slate is heavy. You can’t install this type of roof unless you have a frame that can hold the weight.
Composite
Composite roofs are cheaper than wood shingles or slate, but they have a similar appearance. This means you can get the style and beauty you want at a more affordable price.
However, this material doesn’t last nearly as long as slate. You can expect to go about 30 to 50 years before you have to replace it.
PVS and TPO Membranes
While PVS and TPO membrane roofing systems are affordable, they don’t last as long as most of the other options on this list. Their lifespan is about 20 years, but they may last a few years longer.
Other Things That Affect the Lifespan of Your Roof
The material isn’t the only thing you have to consider when you’re thinking about the lifespan of your roof. There are a number of other factors that can affect the longevity of your roof as well.
Here are a few of the most common.
Installation
If you hire a roofing contractor that doesn’t have a lot of experience, you might not get as many years out of your roof as you thought. Small mistakes during installation can weaken the integrity of your roof, meaning you’ll have to replace it sooner than planned.
Make sure you always do your research and find a quality roofing contractor before you install a new roof.
Weather
Living in a place that experiences extreme weather conditions, such as tornados or heavy snowfall, can also wear out your roof faster. That’s why it’s important to find a roofing material that can withstand the weather in your area.
Maintenance
If you don’t maintain your roof, it might not last very long. You should inspect your roof at least once a year and make any necessary repairs right away. Otherwise, even small damages can turn into big problems.
Make sure you call a professional, such as this repair service, any time you think something’s wrong with your roof.
Ventilation
Ventilation is an important part of your roofing system. Without proper ventilation, your attic will get warm and stuffy. This can cause snow or ice to melt on your roof during the winter, and the moisture can create leaks, warp, or rot.
During the warmer months, a roof that doesn’t have the right ventilation can get humid or moist. This can turn the roof into a breeding ground for rot and mold.
These things require costly repairs to fix, and they can take several years off the lifespan of your roof.
Understanding the Lifespan of Your Roof
So how long does a roof last?
It depends on the roof. Some roofing materials last 30 years while others can last upward of 100 years. A roof that gets proper maintenance will also last longer than one that’s left to its own devices. When it comes time to choose a new roof for your home, make sure you keep these things in mind.
