Abstract: The present invention presents a solution to prevent damage caused by ice dams in the form of a roof shield that includes a plurality of panels in which each panel is secured to at least one other adjacent panel. At the sides of the roof, a single panel on each side is secured to a vertical side surface of the underlying structure. At the front of the roof, each of the panels, or some of the panels are secured to a vertical front surface of the underlying structure. The adjacent panels can be overlapped or contiguous at their ends. To cover the entire span of the roof some adjustment or cutting of a panel may be necessary. This adjustment is accomplished either by altering the overlap amount on adjacent panels, or by custom fitting an end panel to the underlying structure.
