As a property owner, you might wonder how long your roof can withstand the subtropical climate of the Bayou State. To help you get a better understanding, I’m here with a helpful resource that should help you answer your questions. As a roofing professional, I’ve seen which construction materials are best for a particular property in the area.
In this blog post, I’ll explain how the weather of our state can affect different roofing systems and how long a roof lasts in Louisiana. Whether you want to know about asphalt shingles or flat roofing membranes, this guide covers them all. Whether you own a house or a commercial building, learning more about your options is crucial.
So, let’s find out the estimated lifespan of your property’s roof.
How Many Years Does a Roof Last In Louisiana?
Each roofing material has a different lifespan based on a particular set of factors. The durability depends on the resistance of the material to various elements like hail, water, heat, and hurricanes. Here’s the average lifespan of some of the most popular roofing materials in Louisiana:
Asphalt Shingles: 15 to 20 Years
Colorful and durable, asphalt shingles are a popular choice for roofs on countless homes across Louisiana. This affordable and beautiful roofing material is a popular alternative to expensive, heavy, and high-maintenance natural materials like wood, slate, and clay.
On average, an asphalt shingle roof can protect a house for 15 to 20 years in Louisiana. Year-round rainfall can cause issues like shingle granule loss, algae, and leaks, leading to a replacement after 20 years. Fortunately, you can extend your shingle roof’s lifespan with proper roof insulation, ventilation, occasional cleaning, and free roof inspections.
Metal Roofs: 50+ Years
Metal roofs have swiftly gained popularity in Louisiana. They’re sturdy, stylish, and capable of withstanding all kinds of weather. From sweltering summers to intense rainstorms, metal roofs stand tall, protecting homes from significant harm.
However, if you choose low-quality metal panels or bare steel for your roof, it may start rusting and leaking prematurely, reducing the roof’s longevity. But you’ll be relieved to know that good-quality metal roofs, like galvalume steel and aluminum, can last more than 50 years in Louisiana. This lifespan outshines many other roofing materials, especially with frequent maintenance and inspections.
Wood Shake and Shingle Roof: 20+ Years
The rustic appeal of pine and cedarwood roofs has adorned U.S. homes for generations, adding a touch of warmth and character to any neighborhood. However, this natural roofing material requires frequent attention to withstand the weather in Louisiana
Pure wood shake roofs can quickly develop mold, algae, and water stains, increasing the chance that the roofing material will rot rapidly in our rainy state. The average life expectancy of a wood shake roof is around 20 years in Louisiana.
You’ll need to take great care of a wood-shake roof to prevent water and pest damage. Alternatively, you can go for manufactured wood shingles to avoid weather damage, but they can be expensive to customize and install.
EPDM: 30+ Years
When it comes to commercial roofs, EPDM stands out among the rest. This single-ply rubber roofing material is famous for handling Louisiana’s intense climate, allowing your business to thrive for years. EPDM roofs boast an average lifespan of around 30 years in our state, with remarkable resistance to water, UV rays, high winds, and hail.
But extreme heat can cause damage to the membrane, leading to bubbles and splits on its surface. By watching out for any signs of wear and tear every six months, you’ll keep your EPDM roof in excellent condition. Additionally, consider applying a heat-resistant roof coating if your EPDM roof is black. This will help prevent the roofing membrane from retaining heat and deteriorating in summer.
Modified Bitumen: 20 to 25 Years
Another material option for commercial roofing is modified bitumen. This multi-layered roofing system is designed to tackle the challenges Louisiana weather throws its way. From relentless heat to occasional downpours, modified bitumen can withstand it all. But over time, UV rays, heavy rain, and hail can cause the modified bitumen roof to crack, bubble, and split, requiring patchwork or replacement. The repair method depends on its lifespan and the extent of the damage.
Modified bitumen roofs in Louisiana can last around 20 to 25 years with adequate maintenance and inspections. However, factors like installation quality and extreme weather events can influence the average lifespan of any roof. So, choose an experienced and reliable local roofing contractor and ensure the roof is in good hands.
TPO: 23 to 25 Years
Last but certainly not least, we have TPO, a rising star in both residential and commercial roofing. Known for its energy efficiency, durability, and versatility, TPO is capturing the attention of many property owners in the state. However, extreme temperatures and hail can cause TPO roofs to crack and buckle over the years.
TPO roofs typically have an average lifespan of 23 to 25 years, depending on the particular product you are using. It’s a relatively new invention in the flat roofing market, and only a few renowned manufacturers, like GAF and Carlisle, develop high-quality, durable membranes. Their ability to reflect sunlight, resist high winds, and withstand temperature fluctuations adds to their appeal. If you’re looking for a roof that can endure abundant sunshine, TPO might be just what you need.
I hope this information answers your question and helps you understand the status of your current roof. Whether you’re looking to protect your cozy home or ensure the success of your commercial property, choose a roofing material that suits your needs and matches the demands of our local weather.
