Roof Condition

StatusProduction
Includes
  • Parts of flat roof that are discoloured and/or "bubbled" due to long term water damage
  • Parts of a flat roof with visible puddling of water
Excludes
  • Discolouration of tile or shingle roofs
  • Stains from removed objects (such as A/C units)
Usage NotesRoof ponding is a common slowly degrading form of damage for flat roofs, most commonly on commercial and industrial buildings. The confidence and area of ponding can be used to measure a change in severity over time (as both confidence scores and area will increase with the amount and strength of the staining).
