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


Saltbox - one meaning, conflicting with alternative one, from DE:OSM-4D/Roof_table and some editors

Saltbox house roof shape, according to Wikipedia

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).
