When investing in a new roof, you're expecting to get as many years out of it as possible.
One of the most crucial questions customers ask is how long their asphalt roof will last. While a roofing contractor can say 25 or 30 years, you're probably wondering what factors weigh in to the overall lifetime.
Luckily, we're here to help you understand the lifespan of your asphalt roof.
The team at Three Ridges Roofing has been installing asphalt roofs in the Harrisburg area since 1990. We know what it takes to maximize the life of your roof with our workmanship and attention to detail.
The truth is, you should get pretty close to the manufacturer’s lifespan of your roofing materials. But there are a number of factors that ultimately determine how much life you’ll get out of your asphalt roof.
By the end of this article, you'll know how long your asphalt roof should last and the factors that affect its lifespan. And to help save time and make your research a little easier, grab the Asphalt Roof Replacement Cheat Sheet at the very end.
How long will your asphalt roof last?
There are three types of asphalt shingles, 3-tab, dimensional, and luxury. But for this article, we’re going to use the two most common asphalt shingles, 3-tab and dimensional, as examples.
Vented properly and installed correctly, you should get around 80-85% of the life span out of an asphalt roof. That means you can expect to get about 20-22 years out of your 3-tab shingle roof and 25-28 years out of your dimensional shingles.
Remember these numbers are based on your roof being installed using correct roofing principles and having adequate attic ventilation. If it doesn’t, your roof’s life will be cut short and you’ll have to go through the roof replacement process sooner then later.
5 factors that affect the life of your asphalt roof
So, now that you know how long your asphalt roof should last, you’re ready to learn some factors that affect it. Below are 5 factors that help determine the life of your roof.
1. Do you have proper attic ventilation?
Adequate attic ventilation is the most important factor that plays into the life of your roof. If your attic isn’t properly ventilated, then the damage from the trapped hot and cold air will drastically shorten your asphalt roof’s life.
The trapped heat will literally burn up your roof system, leading to a full roof replacement. And because it wasn’t properly ventilated, any warranties you have from the manufacturer on your roofing materials will be voided.

2. Did you hire a reputable roofing contractor?
Hiring a reputable roofing contractor is crucial to your roof investment. When your roof is installed properly, you’re going to get as close to the lifespan of your roofing materials as possible.
That makes hiring a roofing contractor that has a strong installation history that much more important. If they don’t use correct roofing techniques your roof’s life will be cut short and you’ll need a roof replacement well before it’s time.
No matter if you need repairs or a full roof replacement, your contractor plays a huge role in the life you get out of your asphalt roof. A history of proper roof installation isn’t the only thing you need to look for when hiring a local roofing contractor.

3. What are the weather conditions in your area?
Every roof goes through wear and tear from the weather throughout its life. The amount of extreme weather your area gets determines how fast the wear and tear affect your asphalt roof.
For example, if you live in an area that gets a lot of small hail, then your shingles will have granular loss a lot quicker. You won’t be able to file an insurance claim but it’ll definitely shorten your asphalt roof’s life.
There’s nothing you can do about the weather. But be aware the weather of your area will factor into the life of your roof.
4. Which way does your asphalt roof face?
You probably don’t think the direction your home faces factors into the life of your asphalt roof. But the amount of direct sunlight your roof gets affects how long it’ll last.
If the roof faces east and west, each side gets an equal amount of direct sunlight as the sun comes up and goes over your home as the day goes on. If it faces south, then only the south side is going to receive direct sunlight on it all day and it’s also going to take all the wear and tear from the weather.
All of the outside elements are going to factor in the life of your asphalt roof. Talk to your contractor about how the direction your roof faces could affect how long it’ll last.
5. Do you get annual roof maintenance?
Debris sitting on your roof will keep it wet. When your shingles stay saturated it’s not allowing them to perform their main function, keeping you dry. This makes getting annual roof maintenance one of the most important factors to ensure you get the most life out of your roof.
It’s important to keep debris off the roof, out of the valleys, and off the gutter line. When you have annual roof maintenance the common roof problems are caught before they can cause too much damage.
