What Is the Typical Lifespan of an Asphalt Roof?

There are a variety of factors that impact the lifespan of an asphalt roof. From your local weather to the quality of materials your roof is made of, many elements can influence how long your roof lasts. 

If you’re wondering when you should plan your next roof replacement, it’s important to know what type of roof shingle you have on your current roof, how well it was installed, and how long the manufacturer stated it would last. Let’s take a look at the expected lifespan of most asphalt roofing systems and the details about what causes them to last longer. 

What Is the Life Expectancy of an Asphalt Roof?

3-Tab Shingles

As the most budget-friendly roof shingle type, 3-tab shingles have the shortest lifespan of asphalt options. Their manufacturer-stated lifespan is 25 years. They may start to show signs of wear and tear by the 15-year mark. They have the best chance of living out their full lifespan when they are installed by a reputable contractor and maintained well over the years. 

Architectural (Dimensional) Shingles

Also called dimensional shingles, these attractive asphalt shingles are in the mid-range price and offer a random pattern to give your roof a rich, dimensional look, or mimic the look of a wood shake roof. Their manufacturer-stated lifespan of 30 years can be reached when all the conditions are right. They may start to show signs of wear at the 20-25-year mark, so inspect them carefully as they increase in age. Ensuring you keep your roof well maintained and any small repairs attended to promptly will give these shingles the best chance of lasting as long as the manufacturer forecasted. 

Premium (Luxury) Shingles

Premium shingles are also referred to as designer or luxury shingles, and represent the high end of asphalt shingles. They are designed to mimic the look of natural slate tile roofing, boosting your curb appeal significantly. They are larger, more durable, and naturally come with a higher price tag and the most substantial protection for your home. They last approximately 30 years and may last even longer if they are well maintained.

Factors That Impact How Long Your Asphalt Roof Will Last 

1. How well your roof was installed

When roofing components are not installed properly, it negatively impacts your roof’s performance and shortens its lifespan. Inadequate attic ventilation, improper nailing techniques, and installing your roof in poor weather conditions all hinder your roof’s performance over the years.

3. Weather elements in your area

Your roof is exposed to the elements 24/7. It has an essential job of protecting your biggest investment from even severe weather. The amount of rain, snow, ice, hail, sleet, or other harsh weather in your area impacts the lifespan of your roof. 

4. How well your roof was maintained

Keeping your roof well maintained over its lifetime is a vital contributor to its longevity. Without maintenance, small problems can turn into big ones, leaving you with repair issues that could have been avoided. 

It’s important to inspect your roof each spring, fall, and after any major storms. Simply grab a pair of binoculars and step away from your exterior so you can take a good look at your roof from the safety of the ground. If you see things that concern you, contact a reliable roofer to get it professionally inspected. Look for hail damage and cracked, missing, or buckling shingles. And if you notice your roof is sagging, it’s vital to contact a roofer promptly to avoid accidents due to structural issues. 

5. Proper attic ventilation

Proper attic ventilation is a vital factor that directly influences the lifespan of your roofing components. If your attic doesn’t have adequate ventilation, the trapped air can shorten the life of your roof. Without proper ventilation, each summer heat builds up in your attic and causes your roof to age quicker. Adhesives in your decking may deteriorate as a result, and that can make your asphalt shingles crack or curl—shortening your roof’s lifespan. 

6. The direction your roof faces

It may sound surprising, but the direction your roof faces impacts its lifespan. Why? If your roof faces east or west, each side is exposed to an equal amount of direct sunlight throughout the day. But if it faces south, only the south side receives direct sunlight all day and will take the brunt of the wear and tear. And part of your roof may not dry after the rain, creating ideal conditions for moss to grow. Leaves and debris may sit on your roof longer, which can contribute to roof leaks and shorten the life of your asphalt shingles.
