Patent number: 9334651Abstract: Roof systems and related method having a roof deck, a plurality of shingles, and a plurality of fasteners, having a material that partially changes state and displaces into the roof deck material to secure the fasteners and shingles to the roof deck. The shingles can be positioned in an overlapping pattern, and the fasteners can have first portions configured to penetrate into the roof deck and can have at least one material that melts at a threshold temperature. The first portions of the fasteners extend through one or more shingles and penetrate into the roof deck, where the material of the first portion of the fasteners increases in temperature above the threshold temperature, partially changing into a more flowable state, and displaces into voids in the material of the roof deck. Second portions of the fasteners engage the upper surfaces of the shingles to secure the shingles to the roof deck.Type: GrantFiled: June 11, 2015Date of Patent: May 10, 2016Assignee: Owens Corning Intellectual Capital, LLCInventors: Lawrence J.

Publication number: 20160024792Abstract: A laminated asphalt shingle including a base layer, a first decorative layer, and a second decorative layer is provided. The first decorative layer may be affixed to the base layer and to the second decorative layer by a flexible adhesive that permits the first decorative layer to move relative to both the base layer and the second decorative layer without de-bonding. The relative movement of the shingle layers permits the shingle to be folded over the ridge line of a roof without de-bonding or breaking the layers. Additionally, the relative movement of the layers when the shingle is installed over a ridge creates opposing transverse edges in which each layer is offset from the other layers as a result of the shingle bending about a different radius of curvature, thereby providing a dimensional appearance along the transverse edges.Type: ApplicationFiled: June 26, 2015Publication date: January 28, 2016Inventors: Lawrence J. Grubka, Jennifer L. Frey, James E. Loftus, Donn R. Vermilion, Jason D. Guerra

The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.Type: ApplicationFiled: September 30, 2015Publication date: January 21, 2016Inventor: Lawrence J.

Publication number: 20150240496Abstract: Hip and ridge shingles may be single layer or laminated. One hip and ridge shingle has a base layer and a dimensional layer affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. The adhesive line is disposed on only one lateral side of the base layer and dimensional layers to allow movement of another lateral side of the dimensional layer relative to the base layer. Another laminated hip and ridge shingle includes a base layer and a dimensional layer affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. Sealant that comprises at least two parallel lines of sealant material that extend in the machine direction of the base and dimensional layers is disposed on a bottom surface of the base layer for adhering the hip and ridge shingle to an underlying hip and ridge shingle.Type: ApplicationFiled: February 25, 2014Publication date: August 27, 2015Inventors: Lawrence J. Grubka, Jennifer Lynn Frey, Jeffrey W. Smith
