Roof Repair vs Replacement: How to Know Which One You Need (2025)
Shocking Industry Truth
One of the most common questions we hear from Myrtle Beach homeowners is: "Should I repair my roof or just replace the whole thing?" It's a question that can mean the difference between spending a few hundred dollars or tens of thousands—and making the wrong choice can cost you even more in the long run.
The honest answer? It depends. But not in a vague, unhelpful way. There are specific factors that determine whether repair or replacement makes sense for YOUR roof. After 15+ years of inspecting roofs across the Grand Strand, we've developed a clear framework for making this decision.
This guide will walk you through exactly what we look for during an inspection, the questions you should ask, and how to know if a contractor is giving you honest advice or just trying to sell you a new roof you don't need.

When Roof Repair Makes Sense
Repair is often the right choice when damage is localized—meaning it's limited to a specific area rather than spread across the entire roof. Here are the situations where repair typically makes sense:
✓ Your Roof is Under 10-12 Years Old
A relatively young roof with localized damage (missing shingles, small leak) is almost always worth repairing. You still have significant life left in the roofing materials.
✓ Damage is Limited to One Area
A few missing shingles from wind, a single leak point, or isolated flashing failure—these are classic repair scenarios. If 90%+ of your roof is in good condition, why replace it all?
✓ First-Time Issue
If this is the first problem you've had, repair makes sense. But if you've repaired the same roof multiple times over the past few years, the pattern tells a different story.
✓ No Signs of Systemic Failure
When shingles elsewhere look healthy—good granule coverage, lying flat, no curling—the rest of the roof doesn't need to come off because one section had a problem.
Cost Comparison: Repair Scenarios
| Repair Type | Typical Cost | When It's Worth It |
|---|---|---|
| Minor Shingle Repair (1-10 shingles) | $150-$400 | Roof under 15 years, isolated wind damage |
| Flashing Repair | $200-$600 | Single leak point at chimney, vent, or wall |
| Small Leak Repair | $300-$800 | First leak, located quickly, no deck damage |
| Section Repair (50-100 sq ft) | $500-$1,500 | Localized storm damage, rest of roof healthy |
When Roof Replacement Makes Sense
Replacement becomes the smarter choice when damage is widespread or when your roof has reached the end of its functional life. Here are the clear indicators:
✗ Your Roof is 15-20+ Years Old
In Myrtle Beach, asphalt shingles typically last 15-20 years due to coastal conditions (vs. 25 years inland). If your roof is approaching this age and having problems, repairs are often just delaying the inevitable.
✗ Widespread Granule Loss
If you're finding excessive granules in gutters or seeing bare, dark patches across the roof, the shingles are failing systemically. This isn't something you can repair—the protective layer is gone.
✗ Multiple Leaks in Different Areas
One leak is a repair. Three leaks in different parts of the roof? That's a roof telling you it's done. Patching multiple spots is throwing money at a losing battle.
✗ Curling, Cracking, or Buckling Shingles
When shingles curl at the edges, crack, or buckle, they've lost their waterproofing integrity. This happens to the whole roof, not just one area—it means the materials have reached end-of-life.
✗ Deck Damage Visible
If you can see the fiberglass mat showing through, or worse, the wood decking—this isn't a shingle problem anymore. Water has been getting through for a while.
✗ Repair Costs Exceed 30% of Replacement
If a repair estimate comes in at $4,000+ on a roof that could be replaced for $12,000-$15,000—replacement provides better long-term value with warranties and a fresh start.
The "Insurance Factor"
Here's something many homeowners don't consider: if your roof is over 15 years old, your insurance company may be pressuring you to replace it anyway. Some insurers are canceling policies or dramatically increasing premiums for older roofs. A new roof can actually LOWER your insurance costs and reset your coverage to Replacement Cost Value (RCV) for another 10-15 years.
What We Look For: The Professional Inspection Checklist
When we inspect a roof to determine repair vs. replacement, here's exactly what we're evaluating:
Exterior Inspection (On the Roof)
- Shingle condition: Granule coverage, curling, cracking, missing tabs
- Seal strip integrity: Are shingles still adhered or lifting easily?
- Flashing condition: Rust, separation, missing caulk at chimneys, vents, walls
- Ridge and hip caps: Often the first to fail—checked for lifting/damage
- Valleys: High-wear areas that show age first
- Penetrations: Pipe boots, vents, skylights—common leak sources
- Drip edge and fascia: Rot, separation, paint peeling
- Gutters: Granule accumulation indicates shingle wear
Interior Inspection (In the Attic)
This is where many inspectors cut corners—but the attic tells the real story:
- Daylight penetration: Can you see light through the roof boards?
- Water stains: Current or past leak evidence on decking/rafters
- Mold or mildew: Indicates moisture problems
- Decking condition: Soft spots, rot, delamination
- Ventilation adequacy: Proper soffit/ridge venting affects roof longevity
- Insulation displacement: Signs of past leaks or pest intrusion
Red Flag: Inspectors Who Don't Check the Attic
If a roofer gives you a quote without going in your attic, be skeptical. That's where hidden damage lives—and where the honest truth about your roof's condition can be found. We check every attic, every time.
Making the Final Decision: Questions to Ask
Before committing to repair or replacement, make sure you can answer these questions:
1. How old is my roof?
Check your home purchase records, permit history, or previous inspection reports. If you can't find documentation, an experienced inspector can estimate based on shingle style and wear patterns.
2. Is this the first problem, or part of a pattern?
First leak on a 10-year-old roof = repair. Third leak on a 17-year-old roof = replacement time.
3. What's my insurance situation?
Is your insurer threatening non-renewal due to roof age? Have premiums increased significantly? Sometimes replacement is the financially smart move even if repair is technically possible.
4. How long do I plan to stay in this home?
Selling in 2 years? A strategic repair might suffice. Staying for 10+ years? A new roof provides peace of mind and adds home value.
5. What's the cost comparison?
If repair costs exceed 25-30% of full replacement cost, the math usually favors replacement—especially considering the warranty and added home value.
How to Know If a Contractor Is Being Honest
Unfortunately, some contractors push replacement when repair would work—it's a bigger sale. Here's how to spot honest advice:
Signs of an Honest Contractor
- They offer repair as an option—not just replacement
- They show you the damage with photos or video, explaining what they found
- They check the attic—not just the exterior
- They explain the trade-offs honestly, including when repair makes sense
- No high-pressure "today only" tactics—they give you time to decide
- They document everything in writing with clear explanations
Red Flags to Watch For
- Insisting on replacement without explaining why repair won't work
- "Your whole roof needs to come off" without showing evidence
- Refusing to provide a repair estimate for comparison
- High-pressure sales tactics or "limited time" pricing
- Can't answer specific questions about what they found
