When Is a Commercial Roof Repaired, Restored, or Replaced?
Repair fits a roof with damage in a few spots, restoration fits a roof that is worn across its surface but dry underneath, and replacement fits a roof with widespread wet insulation or a failing deck.
| Path | Work involved | Signs it fits |
|---|---|---|
| Repair | Patch seams, reflash curbs, fix drains, swap fasteners | Leaks traced to a handful of details |
| Restore | Repairs plus a full-surface coating over the membrane or panels | Weathered surface, dry insulation, sound attachment |
| Replace | Tear off to the deck and install a new roof | Wet insulation across large areas, rusted deck, repeated failures |
An infrared scan or a few core cuts tell which row a roof belongs in. Owners who keep a log of each leak location see the pattern sooner.
