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.
Claims21
A roofing system, comprising:
- a deck;
- and
- a roofing material positioned over the deck, the roofing material comprising:
- an upper surface adapted to be exposed to an outdoor environment;
- a lower surface;
- and
- at least one energy dissipating feature positioned on the upper surface;
- wherein the roofing material is configured to reduce an energy of an impact of an object striking the roofing material;
- wherein the at least one energy dissipating feature comprises an impact resistant or impact absorbing material configured to absorb or dissipate the energy of the impact of the object striking the roofing material;
- and
- wherein the at least one energy dissipating feature is configured to divert the object striking the roofing material at an angle away from the upper surface of the roofing material, break up the object striking the roofing material, or combinations thereof.
A roofing system, comprising:
- a deck;
- and
- a roofing material positioned along the deck, the roofing material comprising:
- at least one layer having an upper surface configured to be exposed to an outdoor environment;
- and
- at least one energy dissipating feature;
- wherein the at least one energy dissipating feature is configured to reduce an energy of an impact of an object striking the roofing material by breaking up the object upon the impact of the object against the roofing material, diverting the object striking the roofing material at an angle away from the upper surface of the roofing material, or combinations thereof.
A roofing system comprising:
- a deck;
- and
- a roofing material positioned along the deck, the roofing material defining an upper surface of a roof that is exposed to an outdoor environment;
- wherein the roofing material is configured to protect the reef deck from damage due to impact of an object striking the roof, and comprises at least one energy dissipating feature;
- wherein the at least one energy dissipating feature includes an impact resistant or impact absorbing material configured to absorb or dissipate an energy of the impact of the object striking the roofing material;
- and
- wherein the at least one energy dissipating feature is configured to divert the object striking the roofing material at an angle away from the upper surface of the roofing material, break up the object striking the roofing material, or combinations thereof.
