It's one of the most common questions in roofing: do I repair this, or is it time for a full replacement? It's also one where homeowners get pushed into the wrong decision the most often — usually toward replacement they don't need, because that's where the bigger paycheck is. Here's how to think about it honestly.

Start With The Age Of The Roof

This is the single biggest factor. A standard asphalt shingle roof in Memphis is rated for 25–30 years, but our climate usually shaves a few years off. So:

• Under 10 years old: Almost always repair. Even significant damage on a young roof is usually worth fixing rather than replacing.
• 10–15 years old: Usually repair, unless damage is widespread.
• 15–20 years old: It depends. If damage is isolated and the rest of the roof looks good, repair. If granule loss and curling are showing up across the whole roof, replace.
• 20+ years old: Almost always replace. You're at end-of-life regardless of how it looks from the ground.

The 30% Rule

If damaged area covers more than about 30% of the roof, replacement is usually the smarter long-term call. Patching a third of a roof leaves you with mismatched shingles, mismatched age, and a roof that's only as strong as its weakest section.

Storm Damage Vs. Wear

This matters a lot. Wear-based damage (curling, granule loss, brittleness) is age. Storm damage (impact cracks, missing shingles, lifted flashings) is an event. Storm damage on a young-to-mid-age roof = repair. Storm damage on an aging roof = often the trigger for replacement, especially since insurance is involved.

The Repair Cost Ratio

A good rule of thumb: if a repair would cost more than 30% of a full replacement, just replace. You're throwing money at a problem that's going to come back.

Insurance Considerations

If insurance is paying, the calculation shifts. When a claim is approved for full replacement (typical with widespread hail damage), you pay only your deductible regardless of which option you'd prefer. In that scenario, replacement is almost always the right move — you'd be a fool to take a partial repair when the insurance check covers the whole thing.

What We Tell Memphis Customers

About 60% of the inspections we do don't need full replacement — they need a targeted repair, and we tell folks that. About 30% are clear replacements. About 10% are genuine judgment calls where we lay out both options with prices and let the homeowner decide.

What we never do is push someone into a replacement they don't need. A repair customer today is a referral customer for life. That's how we've built the business.

How To Make The Call

If you're not sure, get a real inspection from a roofer who'll show you the photos and explain what they're seeing. We do this for free across Memphis, Bartlett, Collierville, Germantown, and the rest of the metro. Photo report included, no pressure to do anything.
