Other common values and problems
| Value | Comment |
|---|---|
| saltbox | problematic due to conflicting definitions and meanings of "saltbox" in this context[1]. |
| double_saltbox, quadruple_saltbox | As above |
| sawtooth | Factory style roofs |
| cone,conical | Both used rarely |
| side_hipped | Half of a hipped roof, not the same as half-hipped. One vertical gabled side, one 'hip' with three sloped faced. This is common on semi-detached properties where the whole building has a hipped roof but each house has a side_hipped roof |
| lean_to | Unclear, probably should be skillion |
| shed | Unclear, probably should be gabled or skillion |
| gabled_row | Unclear, sometimes used on a sawtooth roof, sometimes a row of gabled terraces |
| crosspitched | Cross shaped roof with two gables at 90degrees. AKA Cross gabled roof |

Other roof tags
| Key | Comment |
|---|---|
| roof:orientation=along/across | For roofs with a ridge the ridge is assumed to be parallel to the longest side of the building (roof:orientation=along). But it can be tagged explicitly with this tag. |
| roof:height=* | The height of the building (i.e. the height of the façade) is calculated as the building's total height=* minus roof:height=*. |
| roof:angle=* | Alternatively to roof:height=*, roof height can be indicated implicitly by providing the inclination of the sides (in degrees). |
| roof:levels=* | Number of floors within the roof, which are not already counted in building:levels=*. |
| roof:direction=* | Direction from back side of roof to front, i.e. the direction towards which the main face of the roof is looking |
Proposed tags
Some roofs (e.g., square buildings) cannot be accurately modeled with the simple techniques described on this page.
Additional roof shapes are suggested in S3DB_Proposals, including advanced approaches for manual modelling (e.g., ProposedRoofLines or parts of OSM-4D/Roof_table).
