At MTS our 18” Blue Label Perfection Cetigrade Cedar roof shingles are the highest quality available and give great coverage. Blue Label Certigrade Shingles are renowned for their insulation qualities, dimensional stability and natural resistance to the elements. Cedar roof shingles contain a natural preservative making them naturally durable in their natural state.
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. Always insist on Certigrade Western Red Cedar Shingles. Our shingles can be viewed in our Showroom (by appointment).
