Lean toward a repair when the roof is young or mid-life, the damage is in one contained area, and you have not been fixing new leaks every season. Lean toward a replacement when the roof is near the end of its life, the damage is spread across several areas, or you keep repairing the same roof over and over. The deciding factors are age, how widespread the damage is, your leak history, and whether repair costs are creeping toward replacement.
Age is the first thing to look at. A roof with plenty of life left is almost always worth repairing, since you are protecting years of remaining service for a small cost. A roof near the end of its expected life is a different story, because spending on a repair only buys a little time before you pay for the replacement anyway. Our page on how long a roof lasts helps you place your roof on that timeline.
Next is how widespread the problem is. One damaged area on an otherwise sound roof points clearly to a repair, and tile roofs make this easy since tiles can be lifted and reset, as our page on repairing a section covers. Damage across several areas, or a failing underlayment throughout, points to a reroof or replacement. Finally, look at your history. If you are calling for a new leak every winter, the roof is telling you it is done, and continuing to patch is spending good money on a losing cause.
| Factor | Repair | Replace |
|---|---|---|
| Roof age | Young or mid-life | Near end of life |
| Extent of damage | One contained area | Several areas |
| Leak history | First or rare leak | Recurring leaks |
| Cost trend | Small vs the roof's value | Repairs nearing replacement cost |
| Underlayment | Sound | Failing throughout |
The math is simple in principle: repair when it protects a roof with real life left, replace when you are pouring money into a roof that is finished. The hard part is judging where your roof actually sits, since a roof can look worse than it is, or better. That is what a roof inspection settles, with a written read on the age, the underlayment, and the extent of the damage. If the signs are pointing to replacement, our page on signs you need a new roof lays them out, and if a fix will do, roof repair handles it. We will give you the straight answer, not the one that sells the bigger job.
