Abstract
This invention, in embodiments, relates to a roofing material comprising (a) a coated or covered substrate and (b) a single sealant applied to a surface of the coated or covered substrate, with the single sealant being free of asphalt. The single sealant exhibits a minimum activation temperature (° C.) (tan δ>1) from −10° C. to 0° C. The single sealant is configured to adhere the roofing material to at least one of (i) an underlying roofing material, (ii) an overlying roofing material, and (iii) a roofing deck substrate.
Claims20
A roofing shingle comprising:
- (a) a coated substrate that is coated on a front surface and a back surface with a coating that comprises at least one of an asphaltic coating, a non-asphaltic coating, a polymer-modified asphalt coating, or a combination thereof;
- (b) a backer strip attached to the back surface of the coated substrate;
- and
- (c) a single sealant applied to the backer strip of the coated substrate,
- wherein the single sealant is a non-asphaltic sealant that is free of asphalt,
- wherein the single sealant exhibits a minimum activation temperature (° C.) (tan δ>1) from −10° C. to 0° C., and
- wherein the single sealant is configured to adhere the roofing shingle to at least one of (i) an underlying roofing shingle and (ii) a roofing deck substrate.
A roofing shingle comprising:
- (a) a coated substrate that is coated on a front surface and a back surface with a coating that comprises at least one of an asphaltic coating, a non-asphaltic coating, a polymer-modified asphalt coating, or a combination thereof;
- (b) a backer strip attached to the back surface of the coated substrate;
- and
- (c) a single sealant applied to the backer strip of the coated substrate, the single sealant comprising a styrene polymer or copolymer and a filler,
- wherein the single sealant is a non-asphaltic sealant that is free of asphalt,
- wherein the single sealant exhibits a minimum activation temperature (° C.) (tan δ>1) from −10° C. to 0° C., and
- wherein the single sealant is configured to adhere the roofing shingle to at least one of (i) an underlying roofing shingle and (ii) a roofing deck substrate.
A roofing system comprising:
- (a) a first roofing shingle comprising:
- (i) a coated substrate that is coated on a front surface and a back surface with a coating that comprises at least one of an asphaltic coating, a non-asphaltic coating, a polymer-modified asphalt coating, or a combination thereof;
- (ii) a backer strip attached to the back surface of the coated substrate;
- and
- (iii) a single sealant applied to the backer strip of the coated substrate,
- wherein the single sealant is a non-asphaltic sealant that is free of asphalt, and
- wherein the single sealant exhibits a minimum activation temperature (° C.) (tan δ>1) from −10° C. to 0° C.;
- and
- (b) a second roofing shingle, wherein the second roofing shingle is adhered to the first roofing shingle via the single sealant.
