|Roof shape type.|
|Used on these elements|
|Status: de facto|
|Tools for this tag|
The key roof:shape=* is used to describe the shape of a building's roof, or the shape of the roof of a building part.
See Simple 3D buildings for more tags used to describe the shape and appearance of buildings.
Common values are shown below, with example diagrams:
You can characterize the roof of a building using a catalogue of well-known roof types.
Other common values and problems
|saltbox||problematic due to conflicting definitions and meanings of "saltbox" in this context.|
|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.|
|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.|
Some roofs (e.g., square buildings) cannot be accurately modeled with the simple techniques described on this page.
