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.

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: A vinyl siding panel which includes a top lock, a medial main body portion, a bottom lock, and a nailing hem adjacent the top lock comprises a channel with nail apertures in the channel base for receiving siding nails. The channel has an open end which has a dimension smaller than the nail head diameter so that the nail head bears against shoulders or bearing surfaces formed adjacent the channel.

The lock structures are generally complementary in shape so that they interlock with other siding panels of like construction. The panel can be reinforced along its length for added rigidity. One area of reinforcement is the channel nailing hem which can be reinforced by extruding additional material to form the channel or by providing an elongated trough-like insert nested within the channel.

The ridge cover generally is a pair of flat, approximately rectangular pieces of asphalt composition roofing material, having a plurality of tabs at one end of each piece which are folded over one another thereby forming a region of increased thickness at that end.
