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.

Tagging

These tags require an area feature tagged was a building=* or 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 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).
