Method of fabricating shake panels

The present disclosure is directed toward unitary modular shake panels, and methods for making and using such shake panels. In one aspect of the invention, a unitary modular shake panel includes an interconnecting section composed of a siding material and several integral shake sections projecting from the interconnecting section. 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. The interconnecting section is preferably a web portion of the fiber-cement siding piece, and the shake sections are different portions of the same fiber-cement siding piece defined by the slots extending in the transverse dimension from the web portion to the second edge of the panel. Modular shake panels in accordance with the invention may be made using several different processes. In one embodiment, for example, a unitary modular shake panel is manufactured by the cutting planks from a sheet of siding material, and then forming slots in the panel to define the web portion and the shake sections. The planks are preferably cut from the sheet in a direction transverse to a wood grain on the surface of the sheet. The slots are preferably cut in the planks in the direction of the wood grain from a longitudinal edge to an intermediate depth within the plank.
