A two-layer laminated roofing shingle is disclosed comprising a posterior layer having an upper portion and a buttlap including a plurality of simulated tabs extending from the posterior upper portion, 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.

Shingle

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.

A laminated roofing shingle is disclosed comprising a posterior layer with simulated tabs and an anterior layer with tabs spaced apart by openings, wherein each posterior simulated tab is partially covered by a corresponding anterior tab, wherein at least one anterior tab has a first anterior tab breadth and at least another anterior tab has a second anterior tab breadth, and wherein at least one anterior opening has a first anterior opening breadth that is about equal to the second anterior tab breadth and wherein at least another anterior opening has a second anterior opening breadth that is about equal to the first anterior tab breadth. Also disclosed is a roofing system comprising a plurality of courses of the shingle.

This invention relates to paper products and/or substrates suitable for being made and/or converted into wallboard tape; which also may be known as joint tape and/or drywall tape, having a pH of at least 7.0 and containing a plurality of cellulose fibers, a wet strength additive, an alkaline sizing agent, and an anionic promoter, as well as methods of making and using the same.
