How Many Years Do Asphalt Shingles Last?

In the U.S., asphalt shingles are found on most residential buildings. The reason behind this popularity is the durability they offer at an affordable price. 

If you are planning to install a new asphalt shingle roof on your building, it’s important to understand its lifespan. Generally, the lifespan of asphalt shingles is between 15 and 30 years, and this range differs depending on the quality and type of product you choose. 

In this article, we will discuss how the lifespan of asphalt shingles differs based on the type. We will also share some extra tips to maintain the longevity of your new asphalt shingle roof. 

Lifespan Of Different Types Of Asphalt Shingles

Here, we will have a quick overview of the number of years asphalt shingles last, depending on their type. 

3-Tab Shingles (15-20 years)

These are the most basic and straightforward asphalt shingle type. They were once a very popular choice, especially for residential properties. 3-Tab shingles are also known as regular or traditional shingles. Generally, the lifespan of 3-tab shingles is only 15 to 20 years. However, if you choose a good brand and maintain your roof properly, it might last longer. 

Architectural Shingles (20-25 years)

Architectural shingles are mid-range shingles that are commonly used on buildings. You can easily find many beautiful styles, features, and colors from different brands. They offer a more dimensional appearance than 3-tab shingles. The lifespan of architectural shingles is 20-25 years. However, good quality shingles, if installed and maintained correctly, can exceed 25 years.

Luxury/Premium Shingles (25-30 years)

Luxury asphalt shingles are the premium range you’ll find on the market. These shingles have a more tough construction and better appearance than the other two types. Premium asphalt shingles have a thicker design, so you can expect them to last for 20 to 30 years. Again, the quality of the product, its installation, and maintenance practices all influence the lifespan of luxury shingles for your building. 

Factors That Directly Affect The Asphalt Shingle Lifespan

The life expectancy of asphalt shingles can vary hugely depending on several key factors. By understanding these, you can better predict and potentially extend the lifespan of your roof.

#1 Climate and Weather Conditions

One of the most significant factors affecting the lifespan of asphalt shingles is the climate and weather in your area. 

In hot climates, shingles may become more vulnerable to damage from UV rays and heat, potentially shortening their lifespan. Conversely, in colder regions, freeze-thaw cycles can cause shingles to crack or become brittle over time.

High humidity levels can also pose a threat to your roof’s longevity. Moisture-rich environments create the perfect conditions for algae and moss growth, which can deteriorate shingles if left unchecked. 

When choosing shingles, look for the relevant features like impact resistance ratings if you live in areas with hailstorms and algae resistance if you live in humid climatic conditions. 

#2 Quality of Installation

The importance of proper installation cannot be overlooked when it comes to the lifespan of your asphalt shingle roof. A roof installed by experienced professionals is more likely to withstand the test of time and weather.

Common installation errors, such as improper nail placement or inadequate underlayment, can lead to leaks and premature aging of your roof. Investing in professional installation can save you money in the long run by increasing the life of your roof.

#3 Ventilation

Adequate attic ventilation is important for regulating the temperature and moisture levels in your home, which directly impacts the lifespan of your asphalt shingles. 

Improper or poor ventilation can lead to heat buildup in your attic, which can cause early deterioration of roofing shingles. Additionally, a lack of proper airflow can trap moisture, potentially leading to mold growth and wood rot in your roof structure.

It’s important to have your attic ventilation system inspected regularly. Proper ventilation helps maintain a consistent temperature, reduces moisture buildup, and can extend the life of your asphalt shingles.

#4 Maintenance Practices

Regular maintenance is very important for extending the lifespan of your asphalt shingle roof. With routine inspections and addressing minor issues promptly, you can prevent small problems from escalating into major, costly repairs. Neglecting maintenance, on the other hand, can lead to premature failure of your roofing system.

Signs It’s Time To Replace Asphalt Shingles

Knowing the signs that indicate it’s time to replace your existing shingles is also important. Here, we will quickly discuss some major signs of asphalt shingle damage. 

#1 Curling Or Cupping

If you notice shingles are curling at the edges or cupping from the center, it’s a clear sign they need to be replaced. This can make your roof more sensitive to leaks and further damage.

#2 Missing Granules

The granules on asphalt shingles serve as a protective layer against UV rays and tough weather. If you’re finding an excessive amount of granules in your gutters or noticing bare spots on shingles, it’s a sign of deterioration.

#3 Cracked Or Missing Shingles

This is an alarming situation that needs attention. Missing or cracked shingles means that the underlying structure of your roof is in danger. While individual shingles can sometimes be replaced, full roof replacement is recommended if the damaged area is large.

#4 Daylight Through The Roof Boards

Check your attic for any signs of light coming through the roof boards. This is a clear indication that your roof has worn thin and needs immediate attention.

#5 Sagging Roof

A sagging roof can indicate structural issues and requires immediate professional assessment. This could be because of long-term water damage, poor ventilation, or other serious problems.
