Your roof is one of the most important parts of your home, but it isn’t something most homeowners think about until there’s a problem. Unfortunately, waiting until you notice a leak can lead to expensive repairs that could have been prevented with a timely roof replacement.
At Barringer Brothers Roofing, we help homeowners throughout O’Fallon determine whether their roof simply needs a repair or if it’s time for a complete replacement. Here are some of the most common signs your roof may be reaching the end of its lifespan.

Your Roof Is Over 20 Years Old
Most architectural asphalt shingle roofs are designed to last around 20 to 30 years, depending on the quality of the materials, installation, ventilation, and weather exposure.
If your roof is approaching or exceeding 20 years old, it’s a good idea to schedule a professional inspection—even if it isn’t leaking yet. Catching problems early can help you avoid unexpected damage.
Missing or Damaged Shingles
One or two missing shingles after a storm may only require a simple repair. However, if you notice widespread missing shingles, curling edges, cracked shingles, or areas where the roof looks uneven, it may indicate the roofing system is beginning to fail.
Damaged shingles leave your home vulnerable to moisture and can quickly lead to larger issues if ignored.
Granules Are Collecting in Your Gutters
As asphalt shingles age, they begin to lose the protective granules that shield them from UV rays and harsh weather.
If you notice excessive granules in your gutters or downspouts, your shingles may be nearing the end of their useful life. Without those granules, shingles deteriorate much faster.
Water Stains or Leaks Inside Your Home
Water stains on ceilings or walls are one of the clearest warning signs that your roof needs attention.
Even a small leak can allow moisture into your attic or walls, leading to mold growth, damaged insulation, and costly structural repairs. If you notice any signs of water intrusion, it’s important to schedule an inspection as soon as possible.
Storm Damage
O’Fallon homeowners know how severe Illinois weather can be. Hail, high winds, and heavy storms can damage shingles even when the roof appears fine from the ground.
Storm damage may include:
- Missing shingles
- Lifted or creased shingles
- Hail impacts
- Damaged flashing
- Fallen tree limbs
After severe weather, a professional inspection can determine whether repairs are enough or if an insurance claim may be appropriate.
Your Roof Looks Worn or Uneven
Sometimes the signs are simply visible from the ground. If your roof appears faded, uneven, sagging, or noticeably worn compared to neighboring homes, it’s worth having it evaluated.
A roof that no longer looks structurally sound may already have hidden issues beneath the shingles.
Don’t Wait for a Leak
Many homeowners assume they’ll know it’s time for a new roof once they see water inside the house. In reality, roof damage often begins long before a leak becomes visible.
Scheduling regular roof inspections helps identify problems early, allowing you to make informed decisions before small issues become major repairs.
At Barringer Brothers Roofing, we provide honest inspections and straightforward recommendations. If your roof can be repaired, we’ll tell you. If replacement is the better long-term investment, we’ll explain why and answer any questions you have.
Frequently Asked Questions
Most architectural asphalt shingle roofs last between 20 and 30 years with proper installation and maintenance.
Not necessarily. However, if your roof is older or showing signs of deterioration, replacing it before leaks develop can prevent more extensive damage.
Yes. Hail, high winds, and severe storms can damage shingles and reduce the overall lifespan of your roof, even if leaks aren’t immediately visible.
The best way is through a professional roof inspection. An experienced contractor can determine whether localized repairs are sufficient or if the roof has reached the end of its service life.
If the damage was caused by a covered event such as hail or wind, your homeowners insurance may help pay for a roof replacement. Normal aging and wear are typically not covered.
