Abstract: An ice dam prevention shield is a device that is installed onto a roof to prevent interior water damage due to the formation of an ice dam and to allow the user to easily remove the ice dam by striking an ice dam that has formed on top of the device with a striking tool. The device features a water-impermeable panel that is installed over the roof shingles and is secured to the roof via a set of roofing fasteners and a set of low head profile fasteners. A cushioning layer may be present in between the water-impermeable panel and the roof in order to allow the water-impermeable panel to flex when struck and facilitate the removal of the ice dam. A bottom anchoring strip is present in order to allow an ice dam to form on top of the water-impermeable panel rather than on top of the roof.
