Oklahoma is known for its unpredictable and often severe weather. From intense hailstorms to scorching summer heat and powerful winds, the climate here puts significant stress on roofing materials. For homeowners in Jenks and surrounding areas, this raises a common question: how long do asphalt shingles last in such challenging conditions? While asphalt shingles typically have a lifespan between 15 and 30 years, Oklahoma’s weather often shortens that expectancy. This post will explore what you can realistically expect from your asphalt shingle roof in Oklahoma and how to recognize when it’s time for a roof inspection from Jenks Roofing Pros.
Average Lifespan of Asphalt Shingles Under Normal Conditions
Asphalt shingles come in two main types: three-tab shingles and architectural shingles.
Three-tab shingles are the more basic option, usually thinner and lighter. They generally last about 15 to 20 years under average weather conditions
Architectural shingles are thicker, heavier, and designed to look more dimensional. These can last 25 to 30 years or more when properly maintained.
Manufacturers often provide warranties that cover 20 to 30 years or longer. However, these warranties mainly cover defects and not damage caused by weather or aging. Real-world performance often falls short of warranty periods, especially in places with harsh climates. This means that even if your shingles are under warranty, Oklahoma’s severe weather can reduce their effective lifespan.
How Oklahoma Weather Affects Asphalt Shingle Lifespan
Oklahoma’s weather conditions create several challenges for asphalt shingles, accelerating wear and damage.
Hail Damage
Hail storms are common in Oklahoma and can cause significant damage to asphalt shingles. Even if the damage is not immediately visible, hail can knock off the protective granules on shingles. These granules shield the shingle from UV rays and water damage. Loss of granules leads to faster deterioration and weakens the shingles’ ability to protect your home.
Bruising from hail can also crack or dent shingles. These bruises may not cause immediate leaks but can reduce the shingle’s durability and lead to premature failure.
Prolonged Heat and UV Exposure
Oklahoma summers bring intense heat and strong sunlight. Over time, this exposure causes shingles to dry out and become brittle. The asphalt can crack, curl, or lose flexibility, making shingles more prone to breaking during storms or high winds.
UV rays break down the shingle’s surface, accelerating granule loss and reducing the overall lifespan. This effect is more pronounced on south-facing roofs that receive the most sun.
High Winds and Severe Storms
Strong winds and severe storms are frequent in Oklahoma. High winds can lift shingles, especially if they are already weakened by age or hail damage. Once lifted, shingles can tear off or allow water to seep underneath, causing leaks and damage to the roof deck.
Storm debris like branches can also scrape or puncture shingles, further reducing their durability.
Signs Your Asphalt Shingle Roof Needs Replacement
Knowing when to replace your roof can save you from costly repairs and water damage. Look for these signs:
Granule Loss: Check your gutters for granules washed off the roof. Excessive granule loss means shingles are losing protection.
Curling or Cracking Shingles: Shingles that curl at the edges or crack are brittle and less effective.
Missing or Damaged Shingles: Missing shingles or those with visible hail bruises or tears need attention.
Leaks or Water Stains: Water stains inside your home or attic indicate roof failure.
Age of Roof: If your roof is over 20 years old, especially with Oklahoma weather exposure, it’s time to consider replacement.
Planning Roof Replacement in Oklahoma
When it’s time for a roof replacement in Oklahoma, choose materials and contractors familiar with local weather challenges. Architectural shingles with higher durability ratings are often better suited for this climate. Regular inspections after storms can catch damage early and extend your roof’s life.
