Grading

Always specify Certigrade Western Red Cedar Shingles

Not all cedar shake and shingle products are alike. Certi-label products, manufactured by Cedar Shake & Shingle Bureau members, assure you of the highest quality standards. Member mills have committed to consistent quality through independent third-party inspections by accredited agencies. Each bundle of product has the mill's distinctive Certi-label tucked under the bundle strap. Asking for "the blue label" or "number one blue label" is not specific enough. Cedar Bureau members' products are the only ones with the Certi brand name on the label.

For quality assurance, always specify Certigrade Western Red Cedar Shingles. The  term  “Blue Label ”  is  a  registered trademark  of  the  Cedar Shake & Shingle  Bureau  trade association  which  has  over  250  member  companies.  Be aware that just because a supplier puts a label in a blue colour on its bundles does not mean that it’s on grade or third party inspected. Certigrade Western Red Cedar Shingles are inspected by legitimate, third party agencies, accredited by the Cedar Shake & Shingle Bureau. 

Silva Timber are a Cedar Shake & Shingle Bureau member. The Bureau monitors and inspects member mills to ensure product quality, grading rules and consistency of Certi-Label cedar shingles and shakes are maintained.

Western Red Cedar is the ultimate green building material. It is legally, responsibly and sustainably harvested in the publicly managed forests of British Columbia, Canada. Less than 1% of standing timber is harvested each year.

For each tree harvested, three are replanted to ensure the forests will exist in perpetuity. Western Red Cedar has a low impact on the environment throughout its life cycle. It requires significantly less energy to produce than man-made alternatives and is bio-degradable.
