A properly done roof repair on a roof that is otherwise in good condition should last as long as the rest of the roof. The repair is only as durable as the roof around it, though.
By the numbers
- Architectural shingles in the Memphis climate typically last 20 to 25 years; 3-tab shingles 15 to 20 years.
- In IBHS testing, weathered shingles hit repeatedly by smaller hail were about 10 times more likely to be damaged by a later severe hailstorm, which is one reason repairs on older roofs don’t hold as long.
Why roof age matters
On a newer roof, a repair restores the roof to full working order. On an older roof, the repaired spot may hold up fine, but the shingles around it are still aging. In the Memphis climate, with long hot summers, humidity, and frequent storms, older shingles tend to crack, curl, and lose granules, so new leaks become more likely.
What makes a repair last
- Fixing the actual source of the leak, not just where water shows up inside.
- Replacing damaged decking or flashing instead of covering it.
- Using shingles and materials that are compatible with your existing roof.
- Sealing and fastening to the manufacturer’s installation requirements.
When to think about replacement
If your roof needs repairs every year or two, the repairs may be costing more than they’re worth. Our Memphis roofing cost guide can help you compare. A roof inspection will show whether a repair or replacement makes more sense.
