When to Repair vs Replace Your Roof: Complete Decision Guide

Repair or replace? Use this framework to make the right financial decision.

The 50% Rule

If repair costs exceed 50% of replacement cost, replace instead.

Age-Based Guidelines

• 0-10 years: Repair unless catastrophic damage
• 10-15 years: Evaluate repair cost vs remaining life
• 15-20 years: Lean toward replacement
• 20+ years: Replace (exceeded expected life)

Replace Immediately If:

• Active leaks in multiple locations
• Sagging or soft spots
• Damage affecting 30%+ of roof
• Structural rot discovered

Repair Makes Sense If:

• Roof under 15 years old
• Damage localized (under 100 sq ft)
• Single incident, not pattern of failures
