How are shingles manufactured?

Shingles are always sawn on both sides from a block of cedar. Most shingles are manufactured using a stationary, upright saw. The block of cedar is moved through the path of the saw by a device called a carriage, which holds the wood firmly, but also alternates the angle of the cut with each stroke. After being cut from the block, the sides of each shingle are then trimmed to create square corners on the product. The material manufactured by CSSB members is then bundled with a Certigrade® label, and shipped for roof installation, or for additional processing to create more tailored sidewall products.
