How Long Does a Asphalt Roof Last

1. The type of asphalt shingles do you have installed  

When installed and ventilated correctly, the three primary categories of asphalt shingles – 3-tab, dimensional, and premium – should each achieve roughly 80% to 85% of their advertised lifespan.

To put it another way, a roof with 3-tab shingles can typically endure for 20-22 years, while roofs with dimensional shingles have a slightly longer lifespan, usually lasting 25-28 years. It’s important to note that these lifespans are directly influenced by the quality of the roof installation and the adequacy of its ventilation.

3-tab shingles: 

3-tab shingles are distinguished by the presence of three asphalt tabs on each piece, and they’re crafted in a single flat layer. These shingles feature a fiberglass base and are coated with mineral granules designed to scatter and bounce back the heat of the sun.

Roofs with a slope often favor 3-tab shingles due to their wide availability, cost-effectiveness, and durability. They generally last between 10 to 20 years and come with a standard manufacturer warranty of 25 years. Their affordability, easy portability, straightforward installation process, and sleek aesthetic make them an ideal choice for budget-conscious households.

Regions with moderate climates, such as the East Coast and Midwest, are best suited for 3-tab shingle roofs. However, if your property is located in an area with extreme winter conditions or regular storms or blizzards, you might want to explore alternative roofing options.[1]

Dimensional shingles: 

Often referred to as architectural shingles, dimensional shingles are constructed from fiberglass and coated with a slim layer of asphalt. This composition lends them a three-dimensional look and texture. Renowned for their superior durability, these shingles typically have a lifespan of about 25 years.

Most manufacturers offer warranties for dimensional shingles that extend up to 30 years, reflecting their sturdy construction. These shingles are built with multiple layers for additional strength and reinforcement.

As a result, you should anticipate investing a bit more in dimensional shingles compared to the cost of 3-tab shingles.

Premium shingles: 

Premium asphalt shingles are designed with a more pronounced profile than 3-tab shingles, enhancing the depth of your roof. They also have an extended lifespan, typically lasting between 20 to 30 years. These premium shingles often exhibit a more luxurious aesthetic and are commonly used in upscale residences.

One of their key benefits is their ability to mimic the appearance of pricier materials such as genuine slate or cedar shake shingles, while being significantly more cost-effective.

If your home is situated in an area that frequently experiences extreme weather conditions like tornadoes, hurricanes, or sizable hail, premium asphalt shingles can be a worthwhile investment. Depending on the installation method, they can resist wind speeds ranging from 110 MPH to 130 MPH.

2. The quality of the roofer’s workmanship  

The longevity of your asphalt roof, whether you need minor repairs or a total replacement, heavily relies on the contractor you choose. Engaging a well-established roofing company ensures you receive top-notch service and roofing materials backed by both manufacturer and workmanship warranties.

To safeguard your roofing investment, it’s crucial to employ a reliable roofing contractor. A commitment to high-quality roofing materials coupled with professional installation will maximize your roof’s lifespan.

Hence, it’s vital to hire a roofing contractor with a solid history of quality workmanship. Poor installation techniques can drastically reduce the life expectancy of your roof, leading to premature replacement.

When on the hunt for a local roofing contractor, merely asking for references from their past projects isn’t sufficient.

3. The weather conditions in your area  

Every roof inevitably undergoes wear and tear due to weather conditions over its lifespan. The rate of deterioration of your asphalt roof is directly related to the harshness of the climate in your locality.

Living in areas with intense sunlight exposure, such as southern California, Texas, Nevada, New Mexico, or Arizona, may result in your asphalt shingle roof having a shorter lifespan compared to those in the Midwest or Northeast.

This is because asphalt roofs in hotter climates are more susceptible to thermal shock or heat-induced issues that can cause cracking, leading to early roof failure.

Moreover, if you live in an area frequently hit by small hail, your shingles will experience accelerated granular loss. This will shorten your asphalt roof’s lifespan, and it’s important to note that this may not be covered by insurance claims.

Therefore, if you reside in a warmer region with an asphalt shingle roof, regular inspections are advisable. If you’re considering installing an asphalt shingle roof in a warm climate, it’s crucial to get a professional roofer’s endorsement first. While you can’t control the weather, being aware of its impact on your roof’s longevity is essential.

4. Do you have proper attic ventilation? 

The condition of your roof largely depends on the effectiveness of your attic’s ventilation. A properly ventilated attic helps maintain a consistent temperature throughout the year by minimizing the accumulation of heat and moisture during various seasons.

Roof vents play a crucial role in ensuring adequate air circulation as they aid in releasing excess heat and moisture, which if untreated, could potentially damage your property. Preventing your attic from overheating can lead to savings on your energy bills and reduce the risk of destructive ice dams forming on your roof.

Regions experiencing both scorching summers and freezing winters are vulnerable to the effects of heat and moisture accumulation in the attic, though for varied reasons. Damage from extreme temperatures and moisture build-up in a poorly ventilated attic can significantly shorten the lifespan of an asphalt roof.

Unchecked moisture accumulation in your attic may also result in a leaky roof. Moreover, inadequate ventilation could render your roofing materials’ manufacturer warranty null and void.

5. Your asphalt roof’s maintenance 

Can you recall the last time you checked your roof? Have you spotted any cracks or tears, or perhaps an attractive layer of moss? If the state of your roof concerns you, it’s crucial to have regular inspections and maintenance.

Allowing debris to pile up on the roof keeps it damp, providing a conducive environment for moss growth. Constantly wet shingles lose their protective properties, leaving your home exposed to the elements.

Hence, annual preventative roof maintenance is key to extending its lifespan. It’s important not to let anything accumulate on your roof, valleys, or gutter lines and downspouts, as this could potentially lead to roof leaks.

Regular roof maintenance allows for early detection and resolution of common roofing problems, preventing them from causing significant damage.
