General Characteristics
- Shingles and shakes produced from Western Red Cedar (Thuja plicata) have long been the premier wood roofing material of North America. The majority of cedar roofs remain untreated and are known to provide excellent service.
Availability:
NO. 1 Blue Label
- The premium grade of shingles for roofs and sidewalls.
- These top-grade shingles are 100% heartwood, 100% clear, and 100% edge-grain.
NO. 2 Red Label
- A good grade for many applications.
- Not less than 10″ clear on 16″ shingles, 11″ clear on 18″ shingles, and 16″ clear on 24″ shingles.
- Flat grain and limited sapwood are permitted in this grade.
NO. 1 Handsplit & Resawn
- These shakes have split faces and sawn backs.
- Cedar logs are first cut into desired lengths.
- Blanks or boards of proper thickness are split and then run diagonally through a bandsaw to produce two tapered shakes from each blank.
NO. 1 Tapersplit
- Produced largely by hand, using a sharp-bladed steel froe and a mallet.
- The natural shingle-like taper is achieved by reversing the block, end-for-end, with each split.
