The blade portion has a front edge, a plurality of first teeth tapered downwardly away from the front edge for removing shingles and nails from the roof on a forward stroke, a rear edge, and a plurality of second teeth turned upwardly away from the rear edge for removing nails from the roof on a backward stroke. The blade portion also has a flat central plate extending between the front edge and the rear edge, a landing section slightly elevated above the flat central plate, and a step for connecting the flat central plate to the slightly elevated landing section. A plurality of slots is cut into an underside of the landing section and extended rearwardly from the front edge for relieving stress on nails pulled by the first teeth from the roof. A mound is positioned near to the rear edge and has a shoulder for receiving a bead of encircling melted metal. The mound also has a protruding stem with either a bore therethrough for receiving a spring pin or at least one side dimple for receiving melted metal so that there are multiple points of attachment for the replaceable blade portion to the hollow handle portion. The plurality of second teeth aligned along the rear edge may be a plurality of claws separated by tapered gaps.
