Repair makes sense when the roof is relatively young and the damage is limited to a small area. Replacement usually makes more sense when the roof is near the end of its life, damage is widespread, there are repeated leaks, or more than about a third of the roof needs work.
Few home projects feel bigger than a new roof, so it's natural to ask whether a repair will do. The answer depends on a few clear factors.
1. How old is the roof?
Asphalt shingle roofs, the most common type in the U.S., generally last around 20 to 30 years depending on the product, ventilation and weather. A roof in its first half of life is usually worth repairing. A roof near the end of its expected life often isn't.
2. How much of the roof is damaged?
- Small, isolated damage such as a few missing shingles or a flashing leak around a chimney is usually a repair.
- Widespread damage from hail or wind across several slopes usually points to replacement.
3. Are there repeated leaks?
If you've patched the same roof several times, the money may be better spent on a replacement that solves the problem for good.
4. What's under the shingles?
Soft or sagging decking, rot or mold in the attic, or poor ventilation all mean the problem goes deeper than shingles.
5. Your plans for the home
If you plan to sell soon, a newer roof can help with inspections and buyer confidence. If you're staying for years, replacement can avoid repeated repair costs.
What about insurance?
When storm damage is covered, your insurer decides whether it pays for a repair or a full replacement based on the damage. A contractor's documentation helps show the full extent.

Frequently asked questions
How long does an asphalt shingle roof last?
Typically around 20 to 30 years, depending on the shingle quality, attic ventilation, installation and local weather.
Can you replace just part of a roof?
Yes, sections can be repaired or replaced, but matching older shingles can be difficult and a partial replacement may not make sense on an aging roof.
How long does a roof replacement take?
Most residential roof replacements take one to three days once materials are on site, depending on size, complexity and weather.
