Abstract: Various embodiments of the invention provide a roofing element that has improved stacking characteristics. According to various embodiments, roofing elements for installing on a sloped roof are provided, and each roofing element includes a body portion that defines one or more batten lugs and/or weather bars and at least one stacker bar that corresponds with each batten lug or weather bar. The batten lugs, weather bars, and the stacker bars extend outwardly from a lower surface of the roofing element, and each stacker bar includes a lower surface and one or more tapered surfaces that extend between the lower surface of the stacker bar and the lower surface of the body portion. The tapered surfaces are adapted for urging the upper surface of a vertically stacked roofing element away from the lower surface of the roofing element.
