How to Know When to Replace Your Roof

Your roof is your home’s first line of defense against the elements — but how do you know when it's time for a new one? Many Ohio homeowners miss the early signs of roof failure, which can lead to bigger issues like water damage, mold, or energy loss. At Good Guys Roofing, we want to help you recognize the warning signs so you can take action before costly repairs pile up.

1. Your Roof Is 20+ Years Old

Most asphalt shingle roofs last between 20 and 25 years. If your roof is approaching or past that age, it may be time to consider a replacement — even if it looks okay from the ground. Shingles can wear down over time and lose their ability to protect your home, especially after years of Ohio winters and summer storms.

2. You Notice Curling or Cracked Shingles

Take a look at your shingles. Are the edges curling up? Do you see cracks forming across the surface? These are signs that the shingles are aging and becoming brittle. Once this happens, they’re no longer fully waterproof, and your roof becomes vulnerable to leaks.

3. You’re Finding Shingle Granules in the Gutters

As shingles wear out, they begin to shed their protective granules. If you’re cleaning your gutters and noticing lots of dark, sand-like particles, your roof is likely nearing the end of its life. Granule loss reduces your roof’s UV protection and accelerates deterioration.

4. Leaks or Water Stains Inside Your Home

Water spots on your ceiling or walls are a red flag that your roof is compromised. Even small leaks can lead to mold growth, rotted wood, and insulation damage. If you’ve noticed water stains or signs of moisture in your attic, it’s time to call a professional.

5. Missing or Loose Shingles

Strong winds and storms — common in Northwest Ohio — can loosen or blow off shingles entirely. Missing shingles leave gaps in your roof’s protection and increase the risk of water infiltration. If you're seeing patches where shingles used to be, your roof needs attention.

6. Sagging or Uneven Roof Lines

If your roof appears to be sagging or drooping in certain areas, that could indicate underlying structural damage or trapped moisture. A sagging roof is a serious concern that should be addressed immediately by a qualified roofing contractor.

7. You See Moss, Algae, or Dark Streaks

While moss and algae may seem like cosmetic issues, they can trap moisture against the surface of your roof, leading to faster deterioration. If you notice streaks or green growth, it's worth having your roof inspected to prevent long-term damage.

Don’t Wait Until It’s Too Late

Knowing when to replace your roof can save you thousands in future repairs. If you’ve noticed any of these warning signs, the best next step is a professional roof inspection.

FAQ: When to Replace Your Roof

How often should I replace my roof in Ohio? Most asphalt roofs should be replaced every 20 to 25 years. Metal and other materials may last longer, but weather conditions and storm damage can shorten any roof’s lifespan.

Can I wait to replace a leaking roof? Delaying replacement can lead to water damage, mold, and higher repair costs. If your roof is leaking, call a professional for an inspection right away.

Is it better to repair or replace my roof? If the damage is localized or your roof is relatively new, repairs might be enough. But if your roof is older and showing multiple signs of failure, replacement is often more cost-effective in the long run.

Does homeowner’s insurance cover roof replacement? It depends on the cause. Insurance often covers roof damage from storms or unexpected events, but not from age or neglect. We can help you review your policy and provide documentation for a claim.
