Résumé :	Roof-nesting by terns Sternidae is a comparatively recent phenomenon and in Europe remains one that is very unusual. Some nine sites have been identified in Scotland at which nesting on roofs has taken place and this report summarises what is known about these; all were on the east coast of Scotland between Caithness and the Isle of May, the earliest having taken place in Montrose in 1996. The sites selected were mainly the roofs of factories or commercial premises, but included also a farm building and a newly constructed visitor centre with a green roof. Individual colonies have varied in size from a single breeding pair up to a maximum of 160 breeding pairs. The larger colonies typically held both Common and Arctic Terns, the smaller ones just the former. One instance of a breeding attempt on a roof by a Roseate Tern is also noted. Reasons for the adoption of this new breeding habitat and its consequences in terms of conflict with man are discussed.
