Western Red Cedar has been the traditional choice for roofing and siding for many years, and is a very popular choice, due to its aesthetic appeal, classy look, and natural resistance to insects and rot. Western Red Cedar actually has many shades other than red, including blondes, browns, and even yellows. These various shades are a natural occurrence of this species, and are part of the charm of Western Red Cedar. Barn shakes are approximately 3/8 in. thick over the whole shake (no taper).
