Abstract
A roof shake having an elongated body with top and bottom surfaces that extend lengthwise of the body, the body having laterally spaced, elongated edges, and opposite ends. The body bottom surfaces have a taper angled to flatly engage the roof near an upper end of the shake, whereby the shake may be nailed to the roof in spaced relation to the end so that the taper engagement with the roof provides leverage resisting wind up-lift forces exerted on the shake near a lower end of the shake installed in spaced relation to the roof. The bottom surface has hollow shallow cavities to reduce weight. The length and width are such as to reduce number of shakes in installation.
