All Silva Timber Western Red Cedar Shingles and Shakes conform to the Cedar Shingle and Shake Bureau Certi-label grading rules. Each bundle is strapped with a label containing important information to distinguish it as a Certi-brand graded bundle.

The below image shows what to look out for on a bundle. Remember, just having a blue label is not enough to be classed as a Certi-brand Shingle or Shake product and may contain off-grade shingles.
