How long do roof shingles last? This is a question that many people ask when they are looking to replace their roofs. Even though it is a seemingly simple question, there isn’t one answer because no two roofs age in exactly the same way, under nearly identical conditions.
The information below will give you some guidance as to how long shingles last and what factors play into their longevity so you can make an informed decision on what is best for your home.
Factors That Determine How Long Your Shingles Last
There are several factors that determine how long your roof shingles will last but in general, 25 years is about the average lifespan for a roof. The following are some of the most important factors:
Roof material
Some materials are more durable than others. For instance, asphalt shingles typically last for around 20 years, while slate or tile roof last upwards of 100 years.
Workmanship
Hiring a reputable roofer to do the work is a big part of ensuring that your shingles will last for many years.
Region
Where you live will also dictate how long your roof shingles last. For example, a roof in a region with harsh weather conditions will naturally wear down faster than one that is located in an area of the country where there are few extremes.
Proper Attic Ventilation
A properly ventilated attic plays a crucial role in the lifespan of your roof shingles. If your attic is not properly ventilated, your shingles will overheat and deteriorate prematurely.
Shingle Quality
Some manufacturers have higher quality than others, which means they may be more durable and longer-lasting. The quality of the installation is another factor that can impact durability.
Weather
The climate and weather in your area. Extreme weather conditions, such as high winds or hail, can damage shingles and shorten their lifespan.
In Which Direction Does Your Asphalt Roof Face?
You may not think the direction in which your home faces plays a role in the life of your asphalt roof. But it does. The exposure to the sun, how much shade your roof gets, and which direction it faces can affect its longevity.
Maintenance of Roofs
if you have a newer home with good maintenance practices in place (e.g., installation of sealant around vents), your roof shingles could last a long time.
Types of Roof Shingles and How Long They Last
Asphalt Shingles
The average lifespan of asphalt roof shingles is about 17 years, but it can depend on the said factors mentioned above. If you’ve already installed asphalt shingles, the best way to prolong their lifespan is by regularly cleaning them and inspecting them for damage every year.
3 Tab Shingles Roofing
The lifespan of three-tab asphalt shingles is about 20 years, but it can be as long as 30 or even 40 years. Asphalt shingle roof with a “three-tab” design typically has fewer granules than the standard variety (so less surface area to wear out), and this design tends to hold up better in strong winds.
Dimensional Shingles Roofing
The lifespan of dimensional shingles is about 30 years, but it can be as long as 50 or even 60 years. Dimensional shingles are made with a lot of small granules and come in many different styles. The more granules on the surface, the more likely it is that the shingle will wear out prematurely because so much area to be worn away.
Premium Shingles Roofing
Premium shingle roofing usually lasts about 40 years. It is made with a lot of larger granules that are harder to wear away. The style also tends to be more durable, so it can withstand high winds and other extreme weather conditions.
Evaluate Shingle Roof for Damage Before Retiring Them
Even if your roof shingles are old, it doesn’t mean they need to be replaced. Take a look at them and see if they’re damaged. If the granules are missing or there’s visible damage to the shingle itself, then it’s time for a new roof. But if they’re in good condition, you can probably get a few more years out of them.
Replace Damaged Shingles Promptly
If you do have to replace some shingles, make sure you do it quickly. Leaving a damaged area on your roof can lead to even more damage and potential leaks. It’s also important to keep an eye on your roof during bad weather – if there are any signs of damage after a storm, call us to repair your roof immediately.
Conclusion
Shingle roofing can be a great choice, especially if you want to maintain your home’s curb appeal and still need some level of weather protection. However, the best way to determine how long they will last is by closely observing them on an ongoing basis and being proactive about roof repairs. As long as you are diligent in both of these areas, your shingles should last for around 20 years and more.
