Start with the condition of the whole roof
Age is useful background, not a diagnosis. Bring the installation date, maintenance history and previous repair records to the inspection. A sound roof with damage limited to one area presents a different decision from a roof with recurring leaks across several sections.
When a targeted repair is worth considering
- The source of the leak or damaged area can be identified and addressed.
- The surrounding covering, underlayment and decking are in serviceable condition.
- The proposed scope explains which components will be repaired and what remains outside that work.
When to compare a replacement scope
Repeated repairs, leaks in different locations, widespread material deterioration or concerns about the underlying deck call for a broader assessment. Visible sagging is a reason to avoid roof access and seek a professional evaluation, not to try another surface patch.
Compare written scopes, the condition of the remaining system and the likely need for further work—not a fixed age or price-percentage cutoff. Ask how each option addresses the source of the problem.
Review replacement planning questions or start with an inspection. If the concern followed a storm, keep damage documentation and insurance review separate from the repair recommendation.
