Roof Repair or Replacement: How to Decide

A good roofer should not recommend replacement when a repair will do. Equally, repeated repairs on a failing roof can waste money.

A good roofer should not recommend replacement when a repair will do. Equally, repeated repairs on a failing roof can waste money.

When a repair is usually sensible

A repair often makes sense when the defect is localised: a slipped tile, cracked flashing, small flat roof detail or isolated ridge problem.

When replacement becomes better value

Replacement may be better if the roof covering is widely worn, felt has failed across large areas, timbers are affected or the same leak keeps returning.

Use a survey to reduce guesswork

A roof survey can separate urgent defects from long-term wear. That makes it easier to plan budget and avoid panic decisions after heavy rain.
