Western Red Cedar Shingles & Shakes

Overview

Western Red Cedar Shingles Not all cedar shake and shingle products are alike. Certi-label products, manufactured by Cedar Shake & Shingle Bureau members, assure you of the highest quality standards. Member mills have committed to consistent quality through independent third-party inspections by accredited agencies. Each bundle of product has the mill's distinctive Certi-label tucked under the bundle strap. Asking for "the blue label" or "number one blue label" is not specific enough. Cedar Bureau members' products are the only ones with the Certi brand name on the label.

For quality assurance, always specify Certigrade Western Red Cedar Shingles.

Western Red Cedar shingles, shakes and hip & ridge roof tiles have been used for hundreds of years and have proven their durability in all kinds of climates. They can be used to create individual buildings, whether traditional or modern, and their rich, warm colour and texture blend beautifully in any natural environment. The natural effects of aging and weathering give an attractive silvery grey colour in time.

Distribution

A tree of the northern Rocky Mountains and Pacific North-west; its full range extends from Alaska southwards to California, and eastwards along many of the interior ranges of British Columbia, northern Washington, Idaho and Montana to the western slope of the continental divide.

The Tree

The largest of the so-called cedars, it grows to a height of 45m to 75m with a diameter of 1m to 2.5m.

The Timber

The sapwood is narrow and white in colour, and the heartwood is reddish-brown. When freshly felled, the heartwood often displays a marked variation in colour; that from the centre of the log may be a dark chocolate-brown changing to salmon pink nearer the sapwood, or the wood may be variegated with alternate dark and light zones. After conventional high temperature kiln drying, the wood assumes a uniform reddish-brown tone, but after long exposure to weather the colour is lost, and the wood becomes silver-grey. This weathered appearance is sometimes purposely sought by architects, but a further peculiarity of the wood is its ability to take and hold stain of the finest tint without discolouration. The wood is non-resinous, straight-grained, somewhat coarse- textured and exhibits a fairly prominent growth-ring figure It is soft, rather brittle, aromatic, especially when wet and light in weight, about 390 kg/m³ when dried.

Drying

Thin sizes dry readily with little degrade, but the timber generally tends to hold its moisture at the centre and care is needed with thick stock to avoid internal honey-combing and collapse. The timber holds its position well after drying with practically no tendency to warp and check. while movement due to shrinking and swelling in changing atmospheres is small.

Strength

Its light weight and soft timber contributes to low strength properties and compared with European redwood (Pinus sylvestris) it is some 20 to 30 per cent inferior in bending strength, and about 1 5 per cent less stiff. It is also much less resistant to splitting and indentation on side grain than redwood.

Working Qualities

Good - The timber works easily with both hand and machine tools, but its relatively brittle nature, which can cause splintering during some operations, and its soft character, which can lead to chip-bruising, usually means that care is needed in order to obtain the best results during mortising, planing and moulding. A good finish can be obtained, but cutters must be kept sharpened.

Why Specify Certi-label Shingles & Shakes?

The Cedar Shake and Shingle Bureau has served member mills and manufacturers in the Shingle & Shake industry since 1915.

The responsibility for educating the public and building code officials falls on the CSSB. Owing to knowledgeable staff, the Cedar Shake & Shingle Bureau has earned the distinction as the recognised industry authority.

 The Cedar Shake and Shingle Bureau also monitor and inspect member mills for quality assurance, under the stringent grading rules of the Certi-label registered trademark. Only Cedar Bureau members who adhere to the grading rules are allowed to carry the Certi brand name on their shingle label

Certi-label Western Red Cedar Shingles & Shakes are inspected by legitimate, third party agencies, accredited by the Cedar Shake & Shingle Bureau, ensuring quality and consistency from bundle to bundle.

Factors to consider when choosing your Western Red Cedar Shingle & Shake supplier.


Check for Third Party Inspection Agencies

Despite what labels may say, a phone number and/or post office box address does not constitute a legitimate third party inspection agency. Legitimate agencies hold proper accreditations, with trained, experienced staff with employees, an address, phone number and business office that are different from the manufacturer.

 

In-house inspectors are not equivalent to Third Party Inspection Agencies

‘In-house inspectors’ just means the manufacturer’s own staff have inspected their product and declared it fit for sale. Product without third party inspection can often result in a building regulation violation requiring the product to be removed from the build.

 

Check label reads “conforms with” as opposed to “in accordance with” grading rules

Always ask your supplier if the product in question actually meet the grading rules, the wording may be misleading.  

 

A Blue Label isn’t enough

The term ‘Blue Label’ is actually a registered trademark of the Cedar Shake and Shingle Bureau. Just having a blue coloured label doesn’t mean it’s on grade or has been third party inspected.

To specify a Cedar Shake and Shingle Bureau member’s product and grade, ensure ‘Certi-label’ is on the purchase order or specification. Follow this wording with grade, product type, length and width to minimize any ambiguity on the product you want.

Non-certified shingles can lead to poor quality

Without third party inspections, bundles can often be loose, leading to poor coverage, have defects beyond the exposure line, which can lead to a failed installation or have shingles containing flat grain instead of edge grain. Always ask to see the rules which the shingles and bundles have been graded against.

Forest Stewardship Council (FSC) Accreditation

FSC is a world-wide, independent, non-profit, non-governmental organisation representing environmental and social groups and the timber and forestry industry. It aims to generate certification of forestry activity that incorporates clear guidelines and standards covering social, environmental and economic aspects of forest management.

Established in 1993 as a response to concerns over global deforestation, FSC is widely regarded as one of the most important initiatives of the last decade to promote responsible forest management worldwide

The FSC label provides a credible link between responsible production and consumption of forest products, enabling consumers and businesses to make purchasing decisions that benefit people and the environment as well as providing ongoing business value.

Chain of Custody (CoC)

The FSC Chain of Custody (CoC) certification system provides an audit trail from forest to final use. The rigour of the system is ensured by regular independent inspection at all stages in the supply chain.

FSC chain of custody (CoC) tracks FSC certified material through the production process - from the forest to the consumer, including all successive stages of processing, transformation, manufacturing and distribution.

Only FSC CoC certified operations are allowed to label products with the FSC trademarks. The FSC label thus provides the link between responsible production and consumption and thereby enables the consumer to make socially and environmentally responsible purchasing decisions.
