Roof Repair vs. Replacement: How to Decide

Repair is cheaper upfront, but replacement can be the smarter long-term investment. Here's how to think through the decision.

Repair Makes Sense When:

• The roof is less than 15 years old and in otherwise good condition
• Damage is isolated to a small area (less than 25–30% of the roof)
• The repair cost is less than 25% of replacement cost
• The underlying decking and structure are sound
• You plan to sell within 1–3 years and just need to pass inspection

Replacement Makes Sense When:

• The roof is 20+ years old (asphalt) or 30+ years old (architectural shingles)
• More than 30% of shingles are damaged, curling, or missing
• You have multiple leaks in different areas
• The decking or rafters show moisture damage
• You've had the same section repaired more than twice
• Insurance is paying for storm damage — replacement is often covered at similar cost to major repair

The "Five Year Rule"

If your roof will need replacement within 5 years anyway, significant repairs rarely make financial sense. Put that money toward a new roof instead.

Get an Independent Inspection First

Before accepting a contractor's recommendation, consider paying for an independent inspection ($150–$400). An inspector with no stake in the work will give you an unbiased assessment.

Insurance Considerations

If storm damage triggered the assessment, file with your insurance before getting repairs. Some policies depreciate repair costs differently than replacement — and a full replacement may be covered at similar out-of-pocket cost.
