POSTED ON: February 21, 2024

If you’re in the market for a new roof, chances are you’re considering asphalt shingles. This versatile roofing material is known for its affordability, durability and aesthetic appeal. But before you make your roofing material choice, let’s delve into the details to answer the most pressing question: How long can you expect asphalt shingles to last on your Louisiana home?


The Advantages and Drawbacks of Asphalt Shingles


  • Cost-Effective – Asphalt shingles are a cost-effective roofing solution, making them ideal for homeowners on a budget.
  • Aesthetic Versatility – With a variety of colors and designs available, it’s easy to find the perfect match to enhance your home’s curb appeal.
  • Easy Installation – Asphalt shingles can be relatively easy to install, which reduces labor costs and the time it takes to install the roof as opposed to other roofing materials.
  • Durability – Quality asphalt shingles often carry warranties spanning 20-30 years.
  • Weather Resilience – Engineered to withstand various weather conditions, from rain to wind—and even some hail.


  • Limited Lifespan – Asphalt shingles have a shorter lifespan compared to roofing materials like metal or clay tiles.
  • Susceptible to Extreme Weather – Heavy storms can inflict damage to shingles, especially in areas of the country that are more prone to frequent storms (like South Louisiana).
  • Ongoing Maintenance – To ensure longevity and effectiveness, asphalt shingles require periodic maintenance.



How Long Do Asphalt Roofs Typically Last?


The lifespan of asphalt shingles can vary based on factors such as maintenance, climate and the type of shingles you opt for (3-tab shingles vs architectural shingles vs designer shingles). 


On average, you can anticipate a service life of approximately 15-20 years before it’s time for a roof replacement.



5 Maintenance Tips for Prolonging the Lifespan of Your Asphalt Shingle Roof


Looking to maximize the longevity of your asphalt shingle roof? Here’s a checklist for you to keep handy:

  • Routine Inspections – Conduct visual checks for damage or wear at least twice a year. You’ll be looking for damaged or missing shingles.
  • Gutter Maintenance – Keep your gutters clean to prevent damage from water backing up and causing damage to the roof.
  • Trimming Overhanging Branches – Trim any overhanging tree branches to prevent debris from building up on your roof.
  • Timely Repairs – Promptly address any roof issues you see to prevent small issues from becoming much worse over time.
  • Gentle Cleaning – Safely remove algae or moss buildup with a mild detergent. DO NOT use a pressure washer on your roof’s asphalt shingles.



Warning Signs of a Failing Asphalt Shingle Roof


To prevent extensive damage, be on the lookout for these warning signs:

  • Curling or Buckling Shingles
  • Missing Shingles
  • Granule Loss
  • Water Stains or Leaks
  • Algae or Moss Growth



Estimating the Cost of an Asphalt Shingle Roof

On average, asphalt shingles typically range from $70 to $150 per square (100 square feet), with labor costs averaging around $2 to $5 per square foot.
