Homeowner guide
Should you repair or replace your roof?
Not every leak means you need a new roof. Here's how roofers usually think about repair versus replacement.
A repair may be enough when
- The damage is limited to a small area, like a few missing shingles or a flashing leak around a chimney or vent.
- The roof is relatively young and otherwise in good shape.
- The decking underneath is solid.
Replacement makes more sense when
- The roof is near the end of its expected life.
- Shingles are curling, cracking or losing granules across large areas.
- There are multiple leaks, sagging, or soft spots in the decking.
- Repairs keep adding up year after year.
- Your insurer is asking questions about the roof's age or condition.
Get an honest opinion
Ask the roofer to show you photos of what they found and explain why they recommend repair or replacement. For a big decision, a second opinion is always reasonable.
Frequently asked questions
How long does a roof last?
It depends on material, climate, ventilation and installation. Asphalt shingle roofs commonly last a couple of decades, while metal, tile and slate can last much longer.
Can I put new shingles over old ones?
Some areas allow one layer over another, but many roofers recommend a full tear-off so they can inspect the decking. Local codes may limit layers.
