How to Know When It’s Time to Replace Your Roof: 7 Signs to Watch For

If you’re a homeowner, you might be wondering when it’s time for a roof replacement in O’Fallon IL. Knowing the signs you need a new roof can save you money and prevent serious damage down the line.

Whether you’re in O’Fallon, Illinois, or anywhere in the Metro East area, here are the 7 key signs that it might be time to replace your roof:

1. Your Roof Is Over 20 Years Old

Most asphalt shingle roofs last about 20–25 years. If your roof is nearing that age, it’s time to start planning for a replacement—even if it looks okay from the ground. Older roofs are more prone to leaks, sagging, and storm damage.

2. You Notice Curling, Cracked, or Missing Shingles

Damaged shingles are one of the clearest signs of wear and tear. If you see shingles that are curling at the edges, cracked in the middle, or missing entirely, your roof is no longer providing proper protection.

3. Granules Are Collecting in Your Gutters

If you’re finding black or gray granules in your gutters or downspouts, it’s a sign your shingles are breaking down. Granule loss weakens the shingles and shortens your roof’s lifespan.

4. Your Roof Is Sagging

A sagging roof is a serious issue. It usually means there’s moisture trapped beneath the surface, possibly rotting the decking or support structure. Don’t wait—this is a safety hazard that needs immediate attention.

5. You’re Seeing Water Stains or Leaks Inside

Water stains on your ceiling, wet spots in the attic, or mold/mildew growth indoors can all point to a roof leak. Even small leaks can lead to major damage if not addressed quickly.

6. Storm Damage After Heavy Wind or Hail

Here in the Midwest, storms are no stranger. If you’ve had high winds, hail, or heavy rains recently, it’s smart to have a roofing inspection. Storm damage isn’t always obvious from the ground, but it can lead to serious issues down the line. If you’ve had recent storms, it’s a good idea to check for damage.

7. Your Energy Bills Are Going Up

A failing roof can let heat escape during winter and allow too much heat inside during summer. If your utility bills are rising, your roof could be the cause.
