Embodiment Construction

[0065]The preferred embodiments of the present invention and its advantages are best understood by referring to FIGS. 1 through 25, like numerals being used for like and corresponding parts of the various drawings. The different shadings of the individual layers in the drawings are not intended to signify a particular color value or intensity but only to indicate color contrasts between the layers, and each individual layer may be lighter or darker than the shadings indicate; however a color contrast between the layers is optionally employed.

[0066]The first embodiment of the present invention, which relates to two-layer composite roofing shingles having the appearance of variable thickness, will now be described in greater detail by referring to the drawings that accompany the present application.

[0067]Reference is first made to FIGS. 1, 1A, 1B, 2-13, and 14 illustrating top plan views of the inventive two-layer composite shingle having an anterior layer 11 and a posterior layer 12,...

Abstract

A two-layer laminated roofing shingle is disclosed comprising a posterior layer having a headlap and a buttlap including a plurality of simulated tabs extending from the posterior headlap, each simulated tab is connected to at least one adjacent simulated tab by a connecting segment, and an anterior layer having a headlap and a buttlap including one or more anterior tabs extending from the anterior headlap. Also disclosed is a single layer roofing shingle comprising a headlap and a buttlap including a plurality of simulated tabs extending from said headlap, the simulated tabs spaced apart by a plurality of partial slots, and each simulated tab is connected to at least one adjacent simulated tab by a connecting segment. Also disclosed is a roofing system comprising a plurality of courses of the inventive shingles.

Description

FIELD OF THE INVENTION[0001]This invention relates to an improved roofing shingle having the bulk and configuration of more expensive roofing shingles and a roofing system that utilizes the shingles. The inventive roofing shingles have the appearance of thicker shingles and have excellent fire resistance and protection against weather, while retaining the substantially reduced cost of conventional asphalt shingles.BACKGROUND OF THE INVENTION[0002]Roofing products are often divided into three broad groups: shingles, roll roofing, and underlayment. Shingles and roll roofing typically function as outer roof coverings designed to withstand exposure to weather and the elements. Shingles and roll roofing generally contain the same basic components which provide protection and long term wear associated with asphalt roofing products. These components include a base material made from an organic felt or fiberglass mat which serves as a matrix to support the other components and gives the pro...
