Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.

An exemplary shingle includes at least one coated shingle sheet defining a headlap portion and a tab portion each having opposed upper and lower surfaces. A first line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a first thermally activated adhesive material. A second line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a second thermally activated adhesive material having a minimum activation temperature less than a minimum activation temperature of the first thermally activated adhesive material.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a first roofing material, wherein the first roofing material comprises a top surface and a bottom surface. In some embodiments, the top surface of the first roofing material comprises a nail zone with a plurality of fines. In some embodiments, the roofing system includes a second roofing material, wherein the second roofing material comprises a top surface and a bottom surface. In some embodiments, the bottom surface of the second roofing material comprises a plurality of fines. In some embodiments, the roofing system comprises and a patterned adhesive, which directly contacts at least a portion of the plurality of fines in the nail zone and at least a portion of the plurality of fines on the bottom surface of the second roofing material.

A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

Roof shingles are provided, as well as methods of fabricating and using the shingles and roofs comprising the shingles. A shingle can include a plurality of perforations in the protruding part thereof to significantly reduce the pressure in the leading edge, the remainder of the protruding part, and/or in the area behind the sealing strip of the shingle. The perforations can be disposed in the protruding part of the shingle down from the sealing strip. Any water entering the perforations can therefore be blocked by the sealing strips and will flow down the roof slope.

A roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.

A roof deck (20) has plurality of insulated panels (22) secured together by a first plurality of fasteners (54) along their longitudinal edges (28, 29). Additionally, the panels (22) are secured by a second plurality of fasteners (56), transverse to the longitudinal axis (26), to a framework (18). A plurality of washers (60) disperse the force of the second plurality of fasteners (56). The plurality of washers (60) are secured to each of the second plurality of fasteners (56). A membrane (24) covers the roof deck (20).

Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.

A shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

A shingle repair patch is provided that may include a base member and granules as discussed in detail above. An adhesive strip is positioned proximate an upper edge on the underside of the base member, or elsewhere on the underside of the base member. The adhesive strip preferably permanently bonds a rigid lip to the base member. The rigid lip preferably extends beyond the upper edge of the base member. An adhesive strip may be positioned on at least a portion of the bottom side of the rigid lip. Release tape is temporarily affixed to the adhesive strip. The adhesive strip is composed of an adhesive that adheres securely without an extended or heat-induced cure period. Standard adhesive may be applied to the remainder of the bottom of the base member, or further adhesive like that found in the adhesive strip may be applied to the remainder of the bottom of the base member.
