Cedar roof shingles and shakes are renowned for their insulation qualities, dimensional stability and natural resistance to the elements. Cedar shingles contain a natural preservative making them uncommonly durable in their natural state.
For quality assurance, always specify Certigrade Western Red Cedar Shingles. The term Blue Label is actually a registered trademark of the Cedar Shake & Shingle Bureau 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.
