A roofing system includes first and second pluralities of shingles, which include central planar portions. Shingles of each plurality are arranged such that their respective central planar portions are substantially co-planar. Each shingle of the first plurality is adjacent at least one shingle of the second plurality. The central planar portions of shingles of the first plurality are displaced with respect to central planar portions of shingles of the second plurality by a separation distance. Adjacent shingles may be installed such that opposite surfaces of their central planar portions are exposed to view. A surfacing shingle may include a central planar portion and several edge portions. The shingles may be used in a ventilated roofing system, which includes a surfacing structure coupled to a roofing substrate. The surfacing structure is elevated with respect to the substrate such that an airspace is disposed between the substrate and the underside of the surfacing structure. The airspace is made accessible to both first and second portions of the substrate. The ventilated system further includes a first ventilation port at the first portion of the substrate for coupling the airspace to the exterior of the roofing system and a second ventilation port at the second portion of the substrate for coupling the airspace to the exterior of the roofing system.
