Your roof is your home’s first line of defense against the elements. Knowing when it’s time for a replacement can save you from costly repairs and protect your investment. While most asphalt roofs last around 20–30 years, several warning signs may indicate it’s time for a new roof—even sooner.
Key Warning Signs
1. Curling or Buckling Shingles
Shingles that curl, claw, or cup are signs of age or poor ventilation. These damaged shingles can’t properly shed water and may lead to leaks.
2. Granule Loss
If you’re finding granules in your gutters or around your home, it means your shingles are losing their protective coating. This exposes the roof to UV damage and shortens its lifespan.
3. Sagging Roof Deck
Any visible dip or sag in your roof is a serious structural concern. It could mean the roof decking has weakened due to moisture or rot and should be addressed immediately.
4. Daylight in the Attic
If you can see sunlight peeking through roof boards in your attic, it means your roof is no longer sealed properly. Water intrusion is likely next.
5. Age of the Roof
Most asphalt shingle roofs last 20–30 years. Even if there are no visible signs of damage, replacement should be considered once the roof nears the end of its expected lifespan.
Be Proactive, Not Reactive
Waiting for leaks to appear can lead to hidden water damage, mold growth, and expensive repairs. Early replacement can help preserve your home’s structure and even improve resale value.
