Should You Repair or Replace Your Roof?
It is the question every homeowner with roof problems faces: is it worth repairing, or is it time for a full replacement? Here is a practical framework for making that decision.
The 30% Rule
If the repair estimate is more than 30% of what a full replacement would cost, replacement is usually the better investment. You are putting good money toward a roof that will need more repairs soon.
The Age Test
If your roof has used more than 80% of its expected lifespan, replacement makes more sense than repair. An asphalt roof at 22 years (of a 25-year expected life) is not worth a $3,000 repair.
When to Repair
- Damage is limited to one small area
- Roof is less than 10-15 years old
- Issue is isolated (one leak, a few missing shingles)
- No signs of widespread deterioration
- You are selling the home within 2-3 years
When to Replace
- Multiple areas showing damage or wear
- Roof is past 75-80% of expected lifespan
- Repair costs exceed 30% of replacement cost
- Previous repairs have not held
- Visible sagging or structural concerns
- Energy bills are increasing (poor insulation/ventilation)
The Hidden Cost of Repeated Repairs
Three $2,000 repairs over 5 years ($6,000 total) on a roof that ultimately needs a $10,000 replacement means you spent $16,000 instead of $10,000. Track your repair spending. If it is climbing, the math usually favors replacement.
