I am very impressed with the professionalism and craftsmanship of Lenny and his Pinnacle Roofing Pros company. My old cedar shakes roof gave signs of failing. I called PRP for an inspection. During our initial meeting, Lenny checked the roof and pointed out the flaws in the materials, with photos he took with his iPhone. The roof was not fixable and needed replacement. Next, he explained the process and the different materials options I could consider.Stefan S.Redmond, WA

What are CCA Treated Cedar Shakes?

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. For more infor visit Imperials website at
