An integrated air barrier assembly is provided as an integral product in which a fastener-sealing layer is secured between opposed surfaces of a board and an anti-blocking facing layer. The assembly exhibits good fastener sealability, including for larger self-drilling screws. The anti-blocking facing layer maintains the fastener-sealing layer inward of the environment and prevents blocking or sticking of the assembly when stacked. In some embodiments, the anti-blocking facing layer can be a metal film or foil, which can reflect heat away from the fastener-sealing layer, thereby maintaining a lower temperature on the fastener-sealing layer. In some embodiments, the board can be an insulating layer or wood layer. The assembly can be readily installed in a single step during construction.

One aspect of the disclosure is a shingle including a first bituminous sheet at the bottom surface of the shingle, the first bituminous sheet having a lower edge disposed at the lower end of the shingle, the first bituminous sheet having one or more slits extending from the lower edge of the first bituminous sheet toward the upper end of the shingle; and a second bituminous sheet at least partially laminated to a top surface of the first bituminous sheet, the second bituminous sheet having a lower edge disposed adjacent the lower end of the shingle, the second bituminous sheet having one or more tabs being defined by one or more notches formed in the second bituminous sheet, each notch extending away from the lower edge of the second bituminous sheet.

Asphalt-based roofing materials, such as shingles, are disclosed that include a band of a parting material. The asphalt-based roofing material includes at least one asphalt-coated substrate that defines a headlap portion and a tab portion each having opposed top and bottom surfaces; a layer of backdust applied to at least a portion of the bottom surface of the headlap portion and to at least a portion of the bottom surface of the tab portion; a release section of parting material applied to the layer of backdust, where the parting material is included in the in the range of 0.0005 kg/m.sup.2 to 1 kg/m.sup.2; and an adhesive.

A roofing shingle (20) comprises a web (22) of roofing material configured with a first series of sealant material sites (60) and a second series of sealant material sites (62) provided on the roofing shingle (20). The web (22) of roofing material is configured with a length dimension (L) and a width dimension (W). The sealant material sites 60 of the first series are provided along a first axis (66) which is essentially parallel to the length dimension of the web. The sealant material sites (60) of the first series are discontinuous along the first axis (66) and separated from one another along the first axis by a first interval (70). The sealant material sites of the second series (62) are provided along a second axis (68) which is essentially parallel to the length dimension of the web and spaced apart from the first axis (66) with respect to the width dimension. The sealant material sites (62) of the second series are discontinuous along the second axis (68) and are separated from one another along the second axis (68) by a second interval (72), the second interval (72) being different than the first interval (70).

Diecuts are configured for permanent closing of holes and have a carrier comprising an assembly of at least two polymeric films. An upper film of the at least two polymeric films has a basis weight of at least 1.0 kg/m.sup.2 and a lower film of the at least two polymeric films consisting of at least two layers, wherein a first layer is in the form of a polymeric film and faces the upper film, and a second layer is in the form of a functional layer with a side of the lower film, facing away from the upper film, bears an applied adhesive composition.

Asphalt-based roofing materials, such as shingles, are disclosed that include a layer of parting material. The layer of parting material is applied to at least a part of the top, bottom, or both the top and the bottom of the shingle. When the shingle includes the parting material on the bottom, the layer of parting material replaces all or a portion of a backdust layer. When the shingle includes the layer of parting material on the top, the layer of parting material replaces a portion of granules on the shingle. The layer of parting material can be applied to the shingle in patterns and configurations that permit an adhesive to be applied to the shingle and function as intended. The parting material may include a metal salt of a fatty acid, a polyolefin, and/or a crosslinkable silane
