A shingle blank includes a substrate coated with asphalt, a headlap portion, a prime portion, a starter shingle separation line, and first and second ridge shingle separation lines. The headlap portion has a first sealant that extends along the width of the substrate, and the prime portion has a second sealant that extends along the width of the substrate. The starter shingle separation line extends along the width of the substrate and facilitates separation of the shingle blank into first and second starter shingles. The first starter shingle includes the first sealant and the second starter shingle includes the second sealant. The first and second ridge shingle separation lines extend along the height of the substrate from an upper edge of the substrate to a lower edge of the substrate and facilitates separation of the shingle blank into three ridge shingles. Each of the three ridge shingles includes a portion of the first sealant and a portion of the second sealant.

The roof valley batten is configured for use with a roof. The roof valley batten attaches a plurality of shingles to a structure formed by a roof valley and a metal valley. The roof valley batten attaches to the metal valley in a manner that does not require the use of a fastening device that perforates a structure selected from the group consisting of the roof valley and the metal valley. The roof valley batten provides a mounting structure for the plurality of shingles that allows the use of a fastening device that does require the perforation of the roof valley batten. The roof valley batten comprises a mounting surface, a plurality of pedestals and a plurality of channels. The plurality of pedestals attach to the mounting surface. The plurality of channels are drainage channels formed within the plurality of pedestals.

A lightweight interlocking metal roof system for installation onto a steep or inclined structure roof either directly over the roof decking material or over an existing shingle roofing system, with the metal roofing system installed from the roof ridgeline down to the drip edge of the roof gutter. Cooperating outwardly extending flanges and receiving pockets for capturing and interlocking the metal panels of the roofing system create an interlock between and among panel members with overlying edge ends configured to be resistant to lift up due to winds either across the roof or along the roof edges.

An exemplary laminated shingle includes an overlay sheet having a top overlay surface, a bottom overlay surface, a headlap portion, and a tab portion arranged between two-cutouts. The shingle also includes an underlay sheet having a top underlay surface and a bottom underlay surface. The overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface is exposed on a first side of the tab portion and a portion of the top underlay surface is exposed on a second side of the tab portion.
