A vehicular roof structure which has no roof arches includes a roof panel having reinforcing frames on peripheral edges thereof and a curved lower surface having a radius R1 of curvature, a roof lining having a curved upper surface having a radius R2 of curvature, the roof lining being of a laminated structure comprising a support layer having a number of cells, a covering layer covering surfaces of the support layer, and a decorative layer disposed on a lower surface of the covering layer, and a vibration-damping layer having a substantially uniform thickness t and held between and closely against the upper surface of the roof lining and the lower surface of the roof panel, the radii R1, R2 of curvature and the thickness t meeting the relationship: R2</=R1-t, the roof lining having peripheral edges fixed to the reinforcing frames of the roof panel.
