Patent number: 6195951Abstract: A laminated shingle is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior lane generally having granules of lighter shading and the more rearward or posterior plane generally having darker granules. The darker granules in the more posterior plane are visible from the front of the shingle to provide visually sharp, precise delineation between zones of lighter and darker shading. The shingles may be of multi-layer construction with suitable adhesives securing the layers together. The darker granules may be visible from beneath the lower edge(s) of the anterior shingle, to provide a shadow line effect. Alternatively, or in addition thereto, the darker shingle zones from the more posterior plane may be visible through tab-separating slots of the lighter shaded anterior shingle portion.Type: GrantFiled: November 17, 1998Date of Patent: March 6, 2001Assignee: CertainTeed CorporationInventors: Kermit E. Stahl, Michael J. Noone, George W. Mehrer

Patent number: 6092345Abstract: A method is provided for making a shingle by cutting a layer of shingle material to have a headlap area and a tab area, and with a plurality of tabs being present in the tab area, separated by slotted openings. The tab area of the shingle is made to have a predetermined design that has a repeatability in the longitudinal direction, or from one edge of a shingle to another in the right-to-left direction, which repeatability is a function of the length of the shingle between said left and right edges, as well as being a function of the number of tabs in the shingle, with the repeatability being greater or smaller than the length of the shingle in the longitudinal direction. Thereby, a method is provided for producing an ornamental appearance that has a random, natural-looking effect when the shingles are laid up on a roof.Type: GrantFiled: February 4, 1998Date of Patent: July 25, 2000Assignee: CertainTeed CorporationInventors: Husnu M. Kalkanoglu, Joseph Quaranta, Kermit E. Stahl

Patent number: 6044608Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer has granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer. The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.Type: GrantFiled: May 29, 1998Date of Patent: April 4, 2000Assignee: CertainTeed CorporationInventors: Kermit E. Stahl, Michael J. Noone, Joseph Quaranta

Patent number: 5961780Abstract: Apparatus is provided for making a multi-layer shingle by cutting an anterior layer of shingle material to have a headlap area and a tab area, and with a plurality of tabs being present in the tab area, separated by slotted openings. The tab area of the anterior shingle layer has a predetermined design that has a repeatability in the longitudinal direction, or from one edge of a shingle to another in the right-to-left direction, which repeatability is a function of the length of the shingle between said left and right edges, as well as being a function of the number of tabs in the anterior shingle layer, with the repeatability being smaller or greater than the length of the shingle in the longitudinal direction. Thereby, the apparatus produces an ornamental appearance that has a random, natural-looking effect when the shingles are laid up on a roof.Type: GrantFiled: February 4, 1998Date of Patent: October 5, 1999Assignee: CertainTeed CorporationInventors: Husnu M.

Patent number: 5950387Abstract: A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line.Type: GrantFiled: May 11, 1998Date of Patent: September 14, 1999Assignee: CertainTeed CorporationInventors: Kermit E. Stahl, Husnu M. Kalkanoglu, Robert L. Jenkins, R. Allan Snyder

Patent number: 5575876Abstract: A shingle is provided that is especially adapted for application to hips or ridges of a roof. In a preferred embodiment, the shingle is a laminated multi-layer shingle, bent or curled into a preformed shape that is reasonably close to the shape that it will have in the installed condition. The shingle layers are connected together in more than one zone, or in one large zone after sliding relative to one another as the shingle is bent or curled. Preferably, such connection is by means of an adhesive.Type: GrantFiled: February 10, 1995Date of Patent: November 19, 1996Assignee: CertainTeed CorporationInventors: Michael J. Noone, Kermit E.

Patent number: 5501056Abstract: A roofing shingle is provided for shingling a roof with overlapped shingles, wherein the exposed portion of the shingle is selected to be of a height in the installed condition relative to the overall height of the shingle that enhances material utilization, to be at least approximately 44.4% efficient. This is accomplished by using an exposure height of 8 inches relative to an overall shingle height of 18 inches. The shingles are preferably constructed to have either 3 or 4 tabs, thereby having a ratio of exposure height to tab width of either 0.667 or 0.889, respectively. A larger exposure allows one to obtain 200 shingles for each 300 lineal feet of sheet shingle material, when the shingles have 18 inch overall height, and further allows an overall saving in the number of nails required to install a roof. The invention also contemplates variations in tab width within a given shingle and variations in number of tabs from about one to nine tabs in a given shingle.Type: GrantFiled: November 2, 1994Date of Patent: March 26, 1996Assignee: CertainTeed CorporationInventors: Marcia G.
