Roof Repair vs. Replacement: When to Choose
- Repair if damage is localized (under 30% of roof), roof is under 15 years old, and no structural issues exist.
- Replace if damage exceeds 30% of the roof, the roof is over 20 years old, there's widespread water damage, or the roof is sagging.
- Rule of thumb: If repair costs exceed 30% of full replacement cost, replacement is usually more cost-effective long-term.
