Abstract:
A hail resistant roofing system and method includes a roofing substrate such as a shingle or tile or membrane having an array of exposed upwardly projecting features. The features may rise to sharp points and may have side surfaces that are angled relative to the plane of the roofing substrate. The features are spaced and arranged so that a large hail stone capable of damaging the roofing substrate will always impact one or more of the exposed features. This can break up the hail stone into smaller benign pieces or can redirect the energy and direction of the hail stone so that the impact is absorbed without damage to the roofing substrate.
