It’s one of the most common questions homeowners ask: Can my roof be repaired, or do I need a full replacement? The answer depends on several factors including age, extent of damage, and future costs.
In this guide, we’ll help you determine when roof repairs are enough—and when investing in a replacement is the safer, smarter choice.
How Long Should a Roof Last?
The lifespan of your roof depends largely on the material and installation quality.
| Roof Type | Average Lifespan |
|---|---|
| 3-tab Asphalt Shingles | 15–20 years |
| Architectural Shingles | 25–30 years |
| Metal Roofing | 40–70 years |
| Flat Roof Systems | 20–25 years |

When Repairs Are Still a Good Option
Roof repairs make sense when:
- The damage is isolated (e.g., a few missing shingles)
- The roof is under 10–15 years old
- There’s no evidence of moisture beneath the surface
- Storm damage is minor and insurance will cover the fix
Repairs can extend the life of your roof, especially when done promptly and by experienced professionals.
Signs You Need a Full Roof Replacement
1. Widespread or Repeated Leaks
If leaks are occurring in multiple areas—or keep coming back—this points to systemic issues that repairs won’t fix.
2. Shingle Curling, Cracking, or Missing in Large Areas
Once a significant portion of your shingles is deteriorating, patch jobs won’t last and may void your warranty.
3. Visible Sagging or Structural Weakness
A sagging roof deck or uneven roofline is often a sign of deeper structural problems. This requires immediate replacement to prevent collapse or interior damage.
4. Mold or Algae Growth
While cosmetic growth can be cleaned, persistent mold inside your attic signals moisture is seeping in and may be affecting insulation and drywall.
5. Granule Loss in Gutters
As shingles age, they shed protective granules. If your gutters are full of them, your shingles may no longer be doing their job.
6. Roof Age Beyond Warranty
Even if damage isn’t visible, a roof past its intended lifespan (usually 20–30 years for asphalt shingles) should be replaced to avoid sudden failure.
