Western Red Cedar is scientifically classified as a "Durable" species in the United Kingdom and because of this durability it is widely favored by architects and engineers seeking an aesthetically pleasing, light weight alternative to traditional roof and wall tiles. For over a century Western Red Cedar Shakes and Shingles have proven to be a superior material for roof and wall cladding which is durable, warm and resistant to extremes of wind and weather. Tapersawn shakes have the appearance of the smooth faced shingle, but the extra thickness of the shake, allowing for the same installation procedures and exposures of the shake, provided felt underlayment paper is used as is for shakes. Produced by sawing both faces on shingle or taper saw machines, the taper is achieved by the mechanical angle setting of the machinery relative to the saw blade for each cut.
