  • Any shingle roof, regardless of shingle material (we cannot distinguish between wood, metal, laminated asphalt, or any of the numerous shingle materials).
Excludes
  • Any other roof material than the shingle
  • Exclude area of a skylight since there will be no shingle underneath.
  • Area of a chimney if it appears to occupy significant area of the roof.
Suitable Use CasesMost use cases are better served by the vectorised product described in AI Packs. 
Usage NotesThis layer may be useful if other raster analysis is already being performed, and the precise area and location of the roof material is needed.
