ABSTRACT:
A roofing member provides improved thermal expansion relief characteristics when mounted adjacent to other roofing members in laterally extending courses on a roof surface. According to one arrangement, the roofing member has a main body with top and bottom surfaces, and side regions, as well as one or more spacer tabs extending outwardly from one or more of the side regions. Each spacer tab extends outwardly from a location on one of the side regions that is adjacent to one of a set of depressions formed into the bottom surface of the main body. In this way, when thermal expansion of adjacently mounted roofing members occurs causing a compressive force to be applied against particular spacer tabs, the spacer tabs fail in a way that at least partially displaces the respective tabs into the adjacently positioned depressions, thereby reducing the stress loads that adjacent shingles apply to one another.
