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.
Claims10
A roofing system, comprising:
- a deck;
- a roofing material positioned on the deck and having a plurality of layers, the plurality of layers comprising:
- a first layer comprising a thermoplastic polyolefin membrane;
- a second layer attached opposite the first layer and attached to the deck;
- and
- a third layer positioned between the first and second layers so as to define a plurality of pockets within the roofing material, the pockets receiving a filler material therein;
- wherein the filler material is configured to move within each of the plurality of pockets sufficient to reduce an energy of an impact of an object striking the roofing system.
