Includes
  • Structural damage caused by catastrophic events (such as storms)
  • Structural damage caused by long term degradation to the point of failure.
Excludes
  • Roofs under active construction.
  • Temporarily repaired structural damage.
  • Other forms of roof degradation that are unlikely to leak in the event of normal rainfall (ponding, rusting, discolouration).
  • Damaged roof where the building underneath has been fully destroyed (a structurally damaged roof is attached to a building structure).
Suitable Use Cases
  • Most use cases are better served by the vectorised product described in  AI Packs .
Usage Notes

Structural damage is most useful to assess buildings after a catastrophic event - however it can also detect buildings that are run down to the point of no longer being habitable. The expectation is that a roof with structural damage must be urgently repaired in order to keep the building habitable.
