How Long Does An Asphalt Roof Last?

Asphalt shingles are one of the most popular types of roofing for commercial buildings. They are durable and relatively easy to install, making them a great option for many businesses. But how long do asphalt roofs actually last?

On average, Asphalt shingle roofs are expected to last 20-40 years. However, this can vary depending on the quality of the shingles, the climate, and the angle of the roof. For example, roofs in warm climates with a lot of sun exposure may not last as long as those in cooler climates. Additionally, roofs with a steep pitch may last longer than those with a shallow pitch.

While some asphalt shingle roofs like architectural shingles may last 30 years or even last as long as 50 years.

What Can I Do To Extend the Life Of My Roof?

There are a few things that business owners can do to extend the life of their asphalt roofs:

  • Regularly inspect and clean your roof. This will assist you to identify any potential problems early on and take care of them before they become major issues.
  • Trim trees and other vegetation around your building. Overhanging branches can damage your roof and allow moisture and debris to accumulate, which can shorten its lifespan.
  • Make sure your roof is properly ventilated. Good ventilation will help to prevent the build-up of heat and moisture, which can damage asphalt shingles.
  • Have your roof inspected and repaired by a professional when necessary. This will help to ensure that any potential issues are taken care of before they become major problems.
  • Have a commercial roof maintenance program in place. This will ensure that your roof is regularly inspected and cleaned and that any potential problems are taken care of right away. A good maintenance plan will also include regular repairs and replacements of damaged or worn-out shingles.

Following the above steps will help you keep your business protected for many years to come.

Factors That Influence The Average Lifespan of Your Asphalt Shingle Roof

  1. The quality of the shingles: Quality is one of the most important elements influencing the lifespan of your asphalt shingle roof. A high-quality shingle has a thicker protective layer if laminated, which can protect it from the weather for a longer period of time.
  2. The climate in your region: If you live in an area with a lot of heavy rain or snowfall, your roof will be exposed to more moisture, and will have to work harder to protect your home from water damage. This can lead to a shorter lifespan for your roof.
  3. The angle of your roof: The angle of your roof also impacts its lifespan. A steeper roof will shed water and snow more easily, which can help to prolong the life of your roof. However, a roof that is too steep can be more difficult to maintain and clean, which can shorten its lifespan.
  4. The type of decking material: The type of material used for the decking of your roof can also affect its lifespan. For example, a metal decking material is more durable and longer-lasting than a wood or plywood decking.
  5. The quality of the installation: A shingle roof that has been installed properly will last much longer than one that was not installed as carefully. This means ensuring that all of the shingles are aligned correctly and that there are no gaps between them. It is also critical to ensure that the flashing and other sealants are installed correctly to prevent water from getting below the shingles and causing damage.
  6. The maintenance of the roof: A well-maintained roof will last longer than one that is not regularly inspected and repaired. This means that it is important to have your roof inspected at least once a year by a professional. You should also consider repairing any damage to your roof as soon as possible to prevent further damage from occurring.

How Do Warrants Compare To The Life Span Of A Roof?

In most cases, a roof will last longer than the warranty period. The warranty is in place in case of damage or injury due to weather or other emergencies. This protects your investment and ensures that expensive repairs are covered. Higher-quality roofs usually come with longer warranties, giving you more protection. Most roofs last between 25 and 55 years. Factors that affect a roof’s lifespan include the quality of construction, the materials used, and the durability of the roof.

Signs You Need A New Roof

Are your roof shingles cracked?

Do you see any missing granules?

Did you see water damage on the ceiling after a storm?

Are your roof shingles curling or cupping?

Is your roof life more than 25 years old?

If you answered yes to any of these questions, it’s time to have your roof inspected by a professional. They can help you determine if you need a new roof or if it can be repaired.

How Often Should The Asphalt Roof Be Replaced?

A prorated warranty typically lasts 20-25 years, after which the shingles may be replaced as needed. The asphalt roof should be replaced every 20 to 25 years to ensure that your home is protected from the elements. However, If you live in a region where severe rain or snowfall is common, your roof may need to be replaced more frequently. A skilled roofing contractor can assist you in determining the optimum time to replace your roof and will work with you to ensure that any repairs or replacements are completed as fast as possible.

Final Thoughts:

The lifespan of an asphalt shingle roof depends on a number of factors, including the quality of construction, the materials used, the angle of the roof, and the maintenance of the roof. A well-constructed and -maintained roof can last up to 40 years, while a roof in a harsher climate may only last 20-25 years. Warranties are typically offered for 15-25 years, after which point you may need to replace your roof. To ensure that your shingle roof is in good condition and will last as long as possible, it is important to have it inspected regularly by a professional and to address any issues or damage quickly. Ultimately, the best time to replace your asphalt roof is when it has reached the end of its lifespan.
