Abstract: Laminated shingles are manufactured from roll stock roofing material that is wider than that used to make similar laminated shingles. The roll stock includes longitudinal edge strips having a reduced thickness. The roll stock is cut into strips of tabbed top sheets and backing sheets. The strips of material used for the backing sheets are at once wider than commonly used in the industry, and include the longitudinal edge strips of reduced-thickness material. Because the backing sheet is wider two rain seal strips are laid down on the backing sheet prior to being laminated to the tabbed top sheet. The backing sheets are laminated to the tabbed top sheets with the longitudinal edges aligned. The wider backing sheet provides a substantially wider nail zone. In addition, since it allows for a second rain seal strip, provides somewhat more protection against leakage. The portion of the backing sheet that comprises the added width is relatively thinner than the remaining portions of the sheet.

The panel preferably has a quadrilateral shape with first and second edges along a longitudinal dimension that are separated from each other by a width of the panel along a transverse dimension. Additionally, the shake sections are separated from one another by slots extending from the second edge to an intermediate width in the panel. In a preferred embodiment, the panel is composed of a unitary piece of fiber-cement siding with a simulated wood grain running along the transverse dimension.

Abstract: The roof shingle system of the present invention includes rows of shingle elements having parallel, slanting lower edges that are aligned to divert the flow of water away from areas where high flow volumes are not desired toward areas where high flow volumes will not cause harm. Because water flowing down a surface will tend to adhere to that surface, the water flowing down the surface of the shingle system of the present invention will tend to follow the slanting lower edges of the shingle elements in the direction of the slanted edges so as to provide a way to control the flow of water on the surface of a roof.

Abstract: Laminated shingles are manufactured from roll stock roofing material that is wider than that used to make similar laminated shingles. The roll stock includes longitudinal edge strips having a reduced thickness. The roll stock is cut into strips of tabbed top sheets and backing sheets. The strips of material used for the backing sheets are at once wider than commonly used in the industry, and include the longitudinal edge strips of reduced-thickness material.

The backing sheets are laminated to the tabbed top sheets with the longitudinal edges aligned. The wider backing sheet provides a substantially wider nail zone. In addition, since it allows for a second rain seal strip, provides somewhat more protection against leakage. The portion of the backing sheet that comprises the added width is relatively thinner than the remaining portions of the sheet.

Abstract: A composite roofing element comprises a first layer of aggregate based material, a second layer of material having a density less than that of the first layer and has a wedge shaped region depending from its underside. The wedge shaped region is preferably integral with the second layer which can be made of an expanded polymer, expanded polystyrene being particularly suitable.

Abstract: The present invention provides a composition ridge or hip covering which creates an appearance similar to that of a wood shake or slate roof. The covering may be easily installed, requires no trimming or folding during installation and may be manufactured with no significant waste of starting material. The covering is accomplished by forming an unfolded sheet of roofing material into a fish-like shape having three distinct portions: a front portion, a body (middle) portion and an end portion. Each portion is tapered and each portion has a specially defined length and taper angle depending upon the shape of the shingle desired. Two thickened multilayers are formed in the body portion by folding the unfolded sheet, one being at the wide end edge of the shingle and the other in the main part of the body portion. The taper angles and lengths of the front portion and end portion are essentially the same.
