A roof paver element includes a plurality of ribs projecting from a planar body portion, the ribs terminating in bottom surfaces having rounded longitudinal boundaries. The ribs are connected to the planar body portion and to one another by fillets. Sides of the planar body portions include depressions which form pressure equalization chambers with the sides of the body portions of adjacent roof paver elements in a roof system to hinder the development of air pressure differentials between the region above the roof paver elements and the spaces below the planar body portions.
