No.1 Grade Blue Label 

  • 100% edge grain, (no flat grain)
  • 100% clear, (no knots or defects)
  • 100% heartwood, (no sapwood)
  • This is the highest grade possible and the product is suitable for use in all cedar roof or siding applications
No.2 Grade Red Label
  • Mixed grain, (unlimited flat grain)
  • Knots and defects allowed in the top 1/3rd of the shingle
  • Small quantity of sapwood is allowed
  • A long lasting and very functional shingle when used correctly
  • A shorter exposure is required for use on roofs and walls
No.3 Grade Black Label
  • Mixed grain, (unlimited flat grain)
  • Knots and defects allowed in the top 2/3rds of the shingle
  • Small quantity of sapwood allowed
  • No visible knots or defects when applied at 3 layers
  • A budget minded grade that can be used very successfully – great value
  • A shorter exposure is required for use on roofs and walls

Western Red Cedar HAND-SPLIT and RESAWN are available in two different grades only – Premium Grade Blue Label and No.1 Grade Blue Label. Most mills make a No.1 Blue Label “Select” quality, an upgraded No.1 Blue Label. Yes, it is confusing…

Hand-split tapered shakes, (tapersplit shakes) and Straight-Split shakes (barn shakes) are almost always available in Premium Grade only.

Certi-Split® Premium Grade Blue Label

  • the highest grade shake available
  • 100% Edge Grain
  • 100% Clear (free of knots)
  • 100% Heartwood
  • quality and prices may vary from mill to mill

Certi-Split® No.1 Grade Blue Label

  • considered to be a lower quality roof due the flat grain component
  • minimum 80% Edge Grain
  • maximum 20% Flat Grain
  • 100% Clear (free of knots)
  • 100% Heartwood
  • quality and prices will vary from mill to mill
“Select” No.1 Blue Label
  • CSSB-97 Certi-Split® grading rules do not definitions for “Select” quality
  • “Select” quality labels are a mill designated upgrade from a No.1 Blue Label
  • “Select” quality label specifications and pricing will vary from mill to mill
  • “Select” quality labels usually indicate the shakes have been edge trimmed, maintain a better average width and are more uniform in thickness / appearance.
  • Non Certi-Split® shakes labeled as No.1 Select may vary significantly in quality and price within the market.
  • We recommend that buyers understand this difference when considering No.1 Grade Blue Label with a “Select” or other similar marketing designation.

Edge grain and flat grain refer to the orientation of the tree’s annular growth rings to the sawn surface of the shingle or the split face of a shake. These terms are used similarly in all aspects of wood products. Please find additional information and photos below to help define the differences.

Edge Grain

  • also known as vertical grain, quarter sawn, rift sawn or radial grain
  • all wood species are more dimensionally stable when sawn or split at 90º to the growth rings, (quarter sawn oak flooring)
  • edge grain better resists movement during changes in moisture content
  • 100% edge grain shingles or shakes will always perform better than grades that allow flat grain
  • the vertical lines on the exposed face of a shingle or shake indicate the fine grained growth rings of Western Red Cedar or Alaska Yellow Cedar
  • looking at the butt end of an edge grain shingle, you will see the annular growth rings standing on end, perpendicular to the surface – like a comb

Flat Grain

  • also known as flat sawn, slab sawn, plain sawn or tangential grain
  • flat grain boards or shingles tend to curl, cup or move more readily than edge grain products, relative to the wood species
  • flat grain cedar shingles and shakes can be used very successfully when the project and application methods are carefully considered. Ask us how to save money with mixed grain products!
  • flat grain can be seen as the open, swirling grain on the face of a shingle or shake
  • looking at the butt end of a flat grain shingle, you will see the annular growth rings running from edge to edge, parallel to the face of the shingle

These three seemingly similar species of coniferous softwoods are all native to North America only, but differ in may ways.  Please find a brief outline of their specifications, features and benefits below.

Western Red Cedar / WRC (thuja plicata)

  • WRC is known as the “tree of life” and used for centuries by the native peoples of the North American west coast
  • known for its excellent properties for exterior applications, WRC has been one of the major softwood species harvested for many decades
  • WRC grows west of the Rocky Mountains from Alaska down through British Columbia, Washington, Idaho and Oregon.
  • WRC varies in colour naturally, from a light yellow to a dark chocolate brown, even within the same tree
  • fresh cut WRC has a sweet and delicious smell, loved by most everyone that experiences it
  • the worlds largest production of shingles and shakes for roofing and siding is produced from WRC, with approximately 75% of the this volume originating from a 60 mile (100km) radius of Vancouver, BC Canada
  • WRC shingles and shakes have been exported worldwide since the early 20th century
  • there are many variations of these products available – different lengths, different thicknesses and different grades all taking a special place in the market.
  • Welcome to WoodRoof.com – we are WRC shake and shingle experts! AYC and EWC too!

Alaska Yellow Cedar / AYC (chaemcyparis nootkatensis)

  • AYC is not actually a cedar, but belongs to the cypress family of trees
  • also known as – Nootka Cypress, Alaska Cypress, Yellow Cypress, Nootka Cedar, Alaska Cedar, Yellow Cedar
  • this species is harvested in much smaller quantities than WRC and the other dominant species of the regions
  • AYC growths along the west coast mountains of USA and Canada,  north through Washington, British Columbia and Alaska
  • AYC tends to grow at higher elevations – approx 3000 ft (900 m) at the 49th Parallel
  • the shorter growing season at high elevation results in fine grain with very tight growth rings
  • AYC is harder and stronger than WRC and EWC, similar to old growth Douglas Fir
  • freshly cut, AYC is a bright and uniform yellow colour
  • AYC turns to a natural silver grey colour relatively quickly with good exposure to the weather
  • AYC has a distinct smell, very different than WRC and immediately recognizable to the trained nose
  • for roofing and siding, AYC shingles and shakes are best when Premium Grade Blue Label – 100% edge grain only
  • AYC is most commonly produced into 18″ (45cm) lengths only
  • the most common AYC products are listed below, and come from mills near Vancouver, British Columbia, Canada
  • No.1 Blue Label 18″ Perfection Shingles
  • No.1 Blue Label 18″ Re-Butted & Re-Jointed Sidewall Shingles
  • Premium Grade 18″ x 5/8″ Tapersawn Shakes

  • is native to the Great Lakes regions, Northeast USA and Southeast Canada.
  • is generally a much smaller tree than WRC or AYC
  • known for its good resistance to decay, is produced primarily into exterior and garden products
  • there is a large production and very strong product for EWC shingles, used mostly for exterior siding applications
  • produced mostly in 16″ (40cm) lengths, EWC shingles are favoured for their tendency to turn a silver grey quickly and naturally
  • EWC is available in other variations of sawn shingles and in same cases split shakes.
  • although used successfully for roofs, they are primarily flat grain (vs edge grain) so care should be taken for proper application methods and longevity expectations
  • these shingles are available in 3 grades:
  • “A” Extras – 16″ shingles – superior grade, no knots or defects for roofs and walls
  • “B” Clears – 16″ shingles – standard grade, no knots or defect on the exposed face, best used for walls
  • “C” 2nd Clears – 16″ shingles – economy grade, exposed defects, rustic appearance, best used for siding
  • all of these EWC shingle products are available “Re-Squared and Re-Butted” for a clean, square appearance on walls
  • all of these EWC shingle products are available with a very good selection of pre-primed, pre-stained and multiple coat stain finishes.

We know cedar shingles and shakes – and the many variables. We want to help our customers understand the potential for differences between grade and quality.

Western Red Cedar shingles and shakes are available in many types and sizes. Products are manufactured and inspected to meet a set of grading rules set out by the Cedar Shake & Shingle Bureau, (CSSB-97) and various building codes in the USA and Canada.

We believe that cedar shingles and shakes should be milled to the highest standard possible. Unfortunately, this is not the case. Some mills and wholesalers produce and promote sub-par materials, while other mills maintain the highest levels of quality possible. This range of qualities available within the same grading rule can be astounding.

We have decided to use the terms, “Budget / Better / Best” rather than, “Good / Better / Best.” We cannot recommend products in the, “Good/Budget” quality level unless you are familiar with the differences. In our opinion, this quality level is not, “good enough.” In most cases, this crap will cost more money in the short and long term.

We hope that these, “quality/price” designations help illustrate the different quality and price point levels in the market. We want to ensure our customers understand these variables and help them make informed decisions. Roofing and siding with cedar are significant decisions. Let us help you. Please call, email or send a message through the website. We are here to help!

The Western Red Cedar No.1 Blue Label 18″ Perfection Shingle is the most common cedar shingle used for roofing. It is popular all over the world.

The Western Red Cedar No.1 Blue Label 18″ Re-Butted & Re-Jointed, (R&R) sidewall shingle is the most common grade and size of shingles used for exterior siding. These R&R shingles have been used for many decades throughout USA and Canada.

What is the difference?

The 18″ R&R shingles are remanufactured from raw 18″ Perfection shingles for a number of reasons:

  • the shingles are selected to meet preferred aesthetics for use on walls
  • the shingles are kiln dried to pre-shrink and stabilize the wood
  • the shingles are cut square and parallel on all four edges – re-butted and re-jointed
  • the square edges speed installation and result in a more refined appearance
  • the kiln dried wood is now ready for priming, painting or staining
  • cardboard boxes keep the shingles clean, dry and ready for shipment
  • available in a variety of grades other than No.1 Blue Label
  • R&R shingles should always be kept clean and dry before installing

Cedar Shingles

Quality Cedar and treated Cedar Shingles and Shakes For Roofing and Siding

Beautiful, Functional, Protective, Durable.

While many roofing and siding materials have been proven to provide an adequate level of protection and style to residential and commercial structures, only a couple of roofing and siding types can match the character that cedar shingles give any structure. Other types of wood can be used for making shingles, but over the years, cedar has become one of the most common materials of choice. Cedar shingles are a smooth sawn, tapered and random width wood tiles used for roofs and walls. Cedar is one of the most durable type of wood that is also one of the easiest wood types to grow.

Cedar shingles provide a very high level of protection yet they have a unique look that is well-suited for old houses and buildings with specific styles. Unlike modern materials used for siding and roofing systems, cedar shake shingles are often used in construction or repair of homes and business establishments for aesthetic purposes. Apart from its curb appeal, many home owners opt to use cedar shake shingles even when other materials are available thanks to their durability, bio-degradable characteristics, low carbon foot print, impact resistance, and limitless design options, among many others.

Cedar Shingles for Homes and Buildings

Cedar shingle roofs will always have a minimum of three layers, (3-ply) exposing less than one third of the shingle length to the weather. This 3-ply application for a No.1 Blue Label has a centuries-long track record. Lower grades require shorter exposures to ensure a watertight roof. We always recommend using a No.1 Grade Blue Label shingle on all primary buildings. Cedar shingle are packaged with four bundles per roofing square – 100 sq ft (9.3 m2) – based on the maximum recommended exposure for each size/type.

These Western Red and Alaska Yellow Cedar roofing shingles can also be used on walls as is!

Frequently Asked Questions

Western Red Cedar shingles and shakes have standardized bundle sizes to cover a certain area, based on how this product is applied. In North America, we often use the term, “roofing square” or “square”. This is know to be a roof or siding area of 100 square feet, (9.3 m2).

A No.1 Blue Label 18″ Perfection is normally applied on the roof at a 5-1/2″ exposure. These shingles are packaged as four bundles per roofing square based on the maximum recommended 5-1/2″ exposure. Therefore, each bundle will yield a coverage of 25 sq ft (2.32 m2) applied at 5-1/2″ exposure, (140mm). This same bundle when applied on the wall at a 7-1/2″ exposure, (190mm) will yield a coverage of 34 sq ft.
