When your roof starts showing problems, the first question is always: should I repair it or replace it? The answer depends on your roof's age, the extent of damage, and the long-term cost calculation. Here's how to decide.
Repair vs. Replace: Decision Table
| Factor | Repair ✅ | Replace ✅ |
|---|---|---|
| Roof Age | Under 15 years | Over 20 years |
| Damage Extent | Localized (1–2 areas) | Widespread or multiple areas |
| Leak Count | Single leak | Multiple leaks |
| Shingle Condition | Mostly intact, few missing | Curling, cracking, widespread loss |
| Cost | $300–$3,000 | $8,000–$25,000+ |
| Selling Soon? | No (extend life 3–5 years) | Yes (new roof boosts sale price) |
| Energy Bills Rising? | No significant change | Noticeable increase |
The 30% Rule
A good rule of thumb: if the repair cost exceeds 30% of a full replacement cost, replace the roof. Repeated repairs on an aging roof rarely make financial sense — you end up spending more over time while living with an unreliable roof.
Cost Comparison Over 10 Years
| Scenario | Year 1 | Years 2–5 | Years 6–10 | 10-Year Total |
|---|---|---|---|---|
| Repeated Repairs | $2,000 | $4,000–$6,000 | $5,000–$8,000 + replacement | $25,000–$35,000 |
| Full Replacement | $15,000 | $0 (under warranty) | $0 (under warranty) | $15,000 |
