Spending $4,000 on a repair when you'll need a full replacement in 18 months is throwing money in the dumpster. Here's how the pros decide.
Rule 1: The 30% Rule
If repair quotes total more than 30% of replacement cost, replace. You'll spend that money on a roof that's already on the clock.
Rule 2: The Age Rule
- ›Shingle past 18 years: lean replace
- ›Concrete tile past 22 years (original underlayment): lean lift-and-relay
- ›Foam past 25 years (no recoats): lean replace
A new roof on top of a failing system is the most expensive mistake we see — twice.
When Repair Is the Right Call
- ›Localized storm damage on an otherwise healthy roof
- ›Less than 10 years old with a single leak source
- ›You're selling within 12 months
When Replacement Is the Right Call
- ›Multiple leak points across the roof
- ›Visible sagging or structural concerns
- ›Approaching end of material lifespan
- ›You plan to stay 5+ years
