The grading of the cedar shake determines how much vertical grain is packed into each bundle and is categorized by a premium grade or a number 1 grade. Regal Roofing & Contracting will only use a premium grade, 100% vertical grain. The cedar shake can be processed with a treatment that can help prolong the life of it. They can be treated with a fire retardant, or can be installed without any treatments. Cedar shakes are commonly milled in lengths of 24” with varied widths from 4” up to just over a foot. The typical thickness of a cedar shake is a medium butt, ½”, or a heavy butt, ¾”. They are installed woven into an asphalt saturated underlayment in 10” exposed courses. When installed correctly a cedar shake roof should be expected to have an average life span of 18 to 25 years depending on the thickness. A cedar shake roof is the contemporary look of the Pacific Northwest and adds beauty to the look of your home.
