The invention relates to a vehicle roof having a sheet metal part (1) and at least one reinforcement (3) adhered thereto, by means of which reinforcement the resistance of the vehicle roof (2) to denting is increased, wherein the reinforcement (3) is constructed in several parts including a core layer (23) and a lower cover layer, in particular a paper layer (19), facing away from the sheet metal part (1), wherein exposure of the vehicle roof (2) to heat (S) causes the reinforcement (3) to thermally expand or contract, creating deformation forces (Ftop , Fbottom) which act on the sheet metal part (1). According to the invention, measures are provided in order to reduce the deformation forces (Ftop, Fbottom) acting on the sheet metal part during exposure to heat (S). 本发明涉及一种车顶，其具有顶钣金件(1)和至少一个与之粘接的顶加强装置(3)，借助所述顶加强装置(3)提高车顶(2)的弯曲刚性，其中，所述顶加强装置(3)由芯层(23)和背离顶钣金件(1)的下覆盖层，尤其是纸层(19)多部件地构成，其中，车顶(2)的受热(S)导致顶加强装置(3)的热膨胀或收缩，即形成作用在顶钣金件(1)上的变形力(Foben，Funten)。根据本发明提供措施以便减少受热(S)时作用在顶钣金件(1)上的变形力(Foben，Funten)。
