Handsplit cedar shakes feature a rough split face and sawn back. Typical cedar shakes come in two different butt thicknesses; ½” (commonly referred to as Mediums in the roofing industry) and ¾” (commonly referred to as Heavys). Handsplit cedar shakes roofs are popular on traditional, ranch, historical and vacation homes or residential structures designed to blend with the natural and/or rustic surroundings.


In comparison, Tapersawn cedar shakes are between a sawn shingle and a split shake. Both surfaces are sawn and provide a more uniformed appearance compared to the rugged handsplit shake

C.C.A. is the abbreviation for Chromated Copper Arsenate. C.C.A. treated shakes have been widely used throughout the world for the past fifty years. The chemical reaction that takes place inside the shakes once treated, results in a stable, non-leachable product that is totally odour free. The arsenate is in a molecular bound state; quite different from elemental arsenic and far less toxic.  If the shakes are treated to industry standards of retention and penetration, then available test and service records indicate that C.C.A. treated wood should last in the excess of forty years, even for marine or ground contact use. In all cases, properly C.C.A. pressure treated wood has been shown to outlast untreated cedar shakes.
