Although the supply of cedar has been greatly diminished in the last decade, it is still possible to get good quality shakes from “old-growth” cedar. Shakes are available in two widths: mediums are 1/2″ – 3/4″ thick, heavies are 3/4″- 1 1/2″ thick at the butt end. The minimum quality shake permitted by code for roofing is a “No.1 Grade” shake. Although there are minimum requirements concerning the amount of flat grain and knots allowed, growth rings per inch, length and width, there is still a wide variation in the quality of No. 1 Grade shakes available.
Premium shakes are also available with 100% vertical grain (also known as edgegrain) made from the highest quality cedar blocks. In addition, all shakes can be pressure treated to obtain a 30 year warranty.
While all of our shakes and shingles are inspected to insure the highest quality of cedar for our customers, our roofers are also instructed to throw out any shakes of questionable quality to insure you get the best possible material on your roof.
