What is Patching?
Roofing Glossary · Maintenance
Definition
A localized repair to a section of roofing to address damage from a specific event — replacing a few blown-off shingles, repairing a small puncture in a flat membrane, or re-adhering lifted shingle edges. Patching is cost-effective when damage is isolated to less than 30% of the roof surface and the surrounding materials are still serviceable. When repairs exceed this threshold or the roof is near end-of-life, replacement is typically more economical.
