Abstract: A roll-form roof ridge vent having alignment means to facilitate ease of installation. The indeterminate-length, single-sheet vent is provided with a pliable medial hinge strip, or a set of expandable live hinges, which enable the otherwise straight vent to be laterally and/or angularly repositioned from its substantially straight configuration. Thus, lateral adjustments can be made to the positioning of the vent as it is being installed so that the vent is centered throughout its length over the roof ridge. The lateral adjustments do not result in buckling of the vent or unwanted distortion.
