Abstract
An impact resistant roofing shingle which includes an asphalt coated substrate whose unexposed surface is laminated to an organic film. A process of forming that shingle includes the step of applying an organic film, by spraying a latex, by applying a rubber polymer modified asphalt, by compressing a plastic film having a higher melting or decomposition temperature than the melting point of the asphalt coating or by applying an adhesive to which a plastic film is applied to the unexposed surface of the asphalt coated substrate.
Claims16
An impact resistant roofing shingle comprising:
- a non-woven glass fiber substrate having an exposed side and an unexposed side;
- an asphalt coating applied to the exposed side and the unexposed side, the asphalt coating having a first melting temperature;
- a plurality of granules directly layered on the asphalt coating of the exposed side;
- an organic film adhered to the asphalt coating of the unexposed side, the organic film having high-impact resistance qualities and a second melting temperature;
- and
- a rubber polymer modified asphaltic adhesive adhered to the asphalt coating of the unexposed side and adhered to the organic film, the modified asphaltic adhesive having a third melting temperature,
- wherein the third melting temperature is higher than the first melting temperature thereby allowing the modified asphaltic adhesive to prevent and seal cracks that may develop in the roofing shingle, and the second melting temperature being independent from the first and third melting temperatures.
