A ridge cover also useable as a shingle having a three dimensional appearance much like shake, together with methods of making and using the same are disclosed. In one embodiment, right isosceles triangular pieces of asphalt composition roofing material are cut. Thereafter, the material on each side of the center line bisecting the right angle is folded under the top surface of the asphalt composition material a plurality of times in a Z-fold manner along lines approximately parallel to the center line to effectively progressively thicken the material at the respective side of the center line, the folding pattern for the two sides being symmetrical with each other. In manufacture, the triangle shaped pieces may be cut from a roll of material with no waste, may be progressively folded, stacked for shipment in a substantially solid stack, easily bent over a ridge during installation, and nailed into position utilizing hidden nails to obtain double coverage on hip and ridges in a manner simulating the outline of a heavy wood shape hip and ridge cover. The symmetry of the cover makes the same also useful as a shingle for a pronounced three dimensional hidden nail double coverage installation. Alternate embodiments and methods are disclosed.
