Roofing shingles are disclosed that are capable of self-adhering to a roof deck or underlayment and/or other roofing shingles and that require few or no mechanical fasteners to remain attached to the roof. By appropriate positioning of sealant lines on the shingle, direct adhesion between the shingle and the roof deck or underlayment and/or other roofing shingles can be achieved. If the shingle is laminated, the layers may be mechanically attached with indentations in the common bond area. The nail zone of the shingle may be visually indicated with fines and/or one or more paint lines. A roofing system comprising a plurality of courses of the shingles is also disclosed.

A multi-part roofing underlayment having independent release liners, where the underlayment comprises separable portions attached adjacent top edges of the separable portions, creating an interface therebetween into which roofing components may be inserted, easing installation and better mitigating wind-driven rain and ice dam related roof failures. Embodiments provide the multi-part roofing underlayment in sheet and roll forms and with various configurations of release liners, adhesive layers, granular layers, selvedge edges, and plastic layers.

The roof valley batten is configured for use with a roof. The roof valley batten attaches a plurality of shingles to a structure formed by a roof valley and a metal valley. The roof valley batten attaches to the metal valley in a manner that does not require the use of a fastening device that perforates a structure selected from the group consisting of the roof valley and the metal valley. The roof valley batten provides a mounting structure for the plurality of shingles that allows the use of a fastening device that does require the perforation of the roof valley batten. The roof valley batten comprises a mounting surface, a plurality of pedestals and a plurality of channels. The plurality of pedestals attach to the mounting surface. The plurality of channels are drainage channels formed within the plurality of pedestals.

Some embodiments of the present disclosure relate to roofing systems including a substrate and adhesive formulations that are free of asphalt or substantially free of asphalt. Some embodiments of the present disclosure relate to methods of making one or more adhesive formulations that are free of asphalt or substantially free of asphalt. Some embodiments of the present disclosure relate to systems utilizing one or more adhesive formulations that are free of asphalt or substantially free of asphalt.

Devices, systems and methods for providing a retrofit and repair technique and device for asphalt shingle roof coverings or roofing systems that exhibit premature adhesive tab seal failures. A device can have a handle at one end and a blade tip end at the other end has the blade tip inserted under a shingle to be repaired. The device can dispense a row of dabs at a selected location under roof shingle(s). The dispenser can dispense a row of individual dabs by a volume container. Alternatively, the dispenser can have a roll with a plurality of rows of pre-made dabs of adhesive on removable type paper. Once the blade tip end of the tool device is inserted between upper and lower shingles, the dabs are dispensed by removing the release paper, and the device is pulled out with the release tape is wound up, advancing the adhesive cylinders. Next, the worker can press down on the upper shingle. Additional embodiments can include adhesive adapters having dispensing heads that attach to ends of caulking tubes on caulking guns, or to caulking gun cartridges, and the like.

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 sealed tabbed asphalt shingle system and method of sealing around the slots defining the tabs of the installed shingles, prevent the intrusion of water and preventing the lifting of installed shingles by wind forces.
