ABSTRACT:
A wind-resistant shingle and a method of making it is provided in which the rear surface of the shingle is provided with an attached reinforcement layer, which resists upwardly wind-applied bending torque when the shingle is installed on a roof, such that the failure of the shingle when it is bent beyond its elastic limit, is resisted until the shingle has absorbed a high percentage of applied torque.
