An underlayment material has a fiber mat partially infused and/or coated with asphalt and coated with silicone coating. A selvedge edge, may be coated or uncoated. The back of the underlayment has a self-adhesive coating, which is protected before use by a siliconized release film. The upper surface of the underlayment is coated with silicone composition providing waterproofing and radiation control. When unsaturated, the selvedge edge of fibrous material establishes a reinforced bond with an overlying sheet. When saturated with asphalt, the bond at the selvedge edge between adjacent sheets is between the asphalt layer of the selvedge edge and the adhesive on the bottom of the adjacent sheet.

A prefabricated modified bitumen waterproofing membrane includes a middle layer formed of a non-woven polyester and/or fiberglass reinforcement fabric, an upper layer and a bottom layer of modified bitumen asphalt, aluminum flakes on a top surface of the upper layer, and polyolefin film covering the bottom layer. A process for manufacturing the prefabricated modified bitumen waterproofing membrane includes modifying the asphalt with SBS (Styrene-Butadiene-Styrene), APP (Attic Polypropylene) or TPO (Thermoplastic Polyolefin) polymers, saturating the top and bottom sides of the middle layer of reinforcement fabric with the modified asphalt, applying the aluminum flakes to the top surface, and applying a polyethylene film to the bottom surface.

A roofing shingle includes an overlay sheet, an underlay sheet, and a reinforcement member. The overlay sheet includes a headlap portion and a tab portion, wherein the overlay sheet has an overlay sheet height. The underlay sheet is secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. The reinforcement material is secured to a top surface of the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.

A method of making a laminated shingle is provided. The method includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, adhering a reinforcement member to a portion of the asphalt-coated sheet, covering the asphalt-coated sheet, and optionally covering the reinforcement member, with granules to make a granule-covered sheet, dividing the granule-covered sheet into an overlay sheet and an underlay sheet, wherein the overlay sheet has a tab portion normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, and wherein the reinforcement member is adhered to the lower zone of the headlap portion and laminating the overlay sheet and the underlay sheet to make the laminated shingle.

A laminated building sheathing comprises a rigid foam board and a facer. The rigid foam board comprises a drainage pattern formed on a major surface of the foam board. The drainage pattern comprises a drainage channel. The facer is configured to cover the major surface of the rigid form board and to essentially conform to the drainage pattern. The facer is semi-permanently bonded to the drainage channel but permanently bonded to non-channel planar portions of the major surface.

A multi-layer laminated roofing underlayment comprising a sheet of asphalt impregnated felt paper bonded to a sheet of porous non-woven polymer fabric in which the bonding adhesive is hot-melt modified asphalt, spot coated onto the felt paper in order to maintain water vapor permeability.

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 method to manufacture a carrier material including a nonwoven layer of fibers and threads extending in the longitudinal direction of the carrier material includes the steps of supplying a nonwoven layer of fibers, supplying a scrim comprising weft threads including a polymer having a melting temperature equal to or less than the lowest melting temperature of the thermoplastic fibers of the nonwoven layer of fibers, and thermally bonding the scrim to the nonwoven layer of fibers.

Disclosed is waterproofing sheeting that uses a polyester layer that provides high lateral stability and puncture resistance. The waterproof sheeting can be used in many applications including waterproof roof underlayments waterproof sheeting for foundations, underlayment for tile and flooring and various other applications. The waterproof sheeting can be manufactured without many of the problems associated with the granular coatings of existing waterproof sheeting that create excessive wear and environmental hazards.

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.
