When it comes to asphalt shingle roofs, there are a few factors that can determine whether they'll last longer than a Kardashian marriage or fizzle out faster than your New Year's resolution to hit the gym at least 5 times a week. Hey, this is a no-judgment zone! From the climate to the installation process, it takes quite a bit to ensure your roof stands the test of time. While choosing the color of your new roof and designing the ultimate aesthetic is the fun part, other aspects are a teensy bit more important.

Don’t get me wrong, at RoofCrafters, developing your vision is critical to our team of experts, however, paying close attention to installation methods and the quality of materials used is something that never goes out of style. We’ve been in the asphalt shingle game for nearly 30 years now, and while trends come and go, a professionally installed, beautiful new roof has stood the test of time.

All of that being said, if you’re reading this article, you probably have a question or two about your current asphalt shingle roof, or you’re interested in investing in a brand-new one. Well, you’re in luck, because in a few short moments, we’ll be discussing the components that affect the lifespan of your asphalt shingle roof, including the quality of materials used, installation method, maintenance, climate conditions, and roof pitch. So, let’s get started!

What Affects the Lifespan of An Asphalt Shingle Roof?

 

Several different factors affect the lifespan of an asphalt shingle roof including:

  • The quality of shingles used
  • Installation method
  • Maintenance
  • Climate conditions
  • Roof pitch

Quality of Shingles

 

When it comes to picking out shingles for your roof, it's easy to get overwhelmed with the various options available. The type of shingle you choose can make a big difference in how long your roof lasts. If you want your roof to withstand the test of time, you'll want to invest in high-quality shingles. Architectural shingles are a great choice because they're thicker and more durable than other types of shingles, like three-tab shingles.

These top-tier shingles can hold up for 25 years or more without showing any significant damage. So don't skimp on quality or, most importantly, the quality of the contractor, because when it comes to your roofing system, it's worth the investment in the long run.

Installation

 

Did you know that the way your shingles are installed can have a huge impact on your roof's lifespan and wind resistance? It's true! If they're not installed correctly, water can seep underneath and weaken your roof's structure. Proper installation involves nailing patterns, ventilation, and avoiding overdriven nails.

And that's not all - the type of underlayment you choose, like synthetic felt or peel-and-stick options, can also extend the life of your roofing system. Invest in the proper installation and materials now for a secure and durable roof for years to come.

Maintenance

 

Your shingle roof is your home's first line of defense against the elements, so regular maintenance is crucial to keeping it strong and durable. Any damage, no matter how small, must be taken seriously and dealt with swiftly to prevent potentially expensive and dangerous issues down the line. Don't let neglect turn minor problems into major disasters threatening your home's stability and your family's safety.

Climate Conditions

 

Climate can have a significant impact on the durability and longevity of an asphalt shingle roof. Extreme weather conditions such as high winds, heavy rain, hail, snow, and intense heat can all affect the performance of the roof over time. Loose, punctured, or damaged shingles can lead to leaks and more significant problems down the road. In regions with high temperatures, your asphalt shingle roof can become brittle and prone to cracking or curling.

Prolonged exposure to UV rays from the sun can also cause the shingles to fade and lose their protective coating, making them vulnerable to water damage. On the latter, in areas with high rainfall, the asphalt shingle roof can be susceptible to water damage and leaks, especially if the shingles are not properly installed or maintained. That's why it's crucial to consider your region's weather conditions when selecting the proper shingle and underlayment for your roof.

Roof Pitch

 

The roof pitch, or the slope of the roof, can have a significant impact on the lifespan of shingles. The pitch of a roof determines how water and debris flow off of it, which can affect how well the shingles protect the roof from moisture damage. A roof with a low pitch, typically less than 3:12, can be more prone to water damage because water can pool on the surface of the roof rather than flow off quickly.

This can lead to leaks and moisture damage that can shorten the lifespan of the shingles. In addition, low-pitched roofs may not provide adequate ventilation, which can cause excess heat and moisture buildup that can also damage the shingles. Conversely, a roof with a steeper pitch, typically greater than 6:12, can be better at shedding water and debris. This can reduce the likelihood of moisture damage and prolong the lifespan of the shingles. Steeper roofs also tend to provide better ventilation, which can help prevent excess heat and moisture buildup that can damage the shingles.

Is My Asphalt Shingle Roof Built to Last?

 

Understanding the factors that impact shingle roof lifespan is crucial for any homeowner. Investing in high-quality shingles, a proper installation by a qualified, reputable contractor, regular maintenance, and considering your home's climate conditions are all essential factors that will determine your shingle roof's lifespan. While life expectancy may vary depending on a combination of factors, with regular maintenance, a shingle roof should last anywhere from 15-25 years or even longer.

By keeping a close eye on your roof and addressing any issues promptly, you can prolong the lifespan of your shingle roof, saving you money in the long run. If you’re curious about the asphalt shingle roofing options in your area, it’s important to acquire several different roofing estimates from differing companies before choosing the contractor that’s the best fit for your roofing needs.
