Although not as well-known as Western Red Cedar, Yellow Cedar (also known as Alaskan Yellow Cedar or Western Cypress) offers very similar performance characteristics.
Yellow Cedar shakes are a uniform pale-yellow colour when new but will weather to a light silver-grey patina. The wood has a fine texture and straight grain. It is heavier and denser than Western Red Cedar and thus has excellent strength and wear resistance.
Yellow Cedar is naturally durable and naturally resistant to insects. Like Western Red Cedar, it is an extremely stable wood species. It accepts coatings well so that it can be finished with a stain or be left natural.

Yellow Cedar shingles and shakes provide a high degree of insulation, keeping buildings warm in winter and cool in summer. Their low carbon footprint and the fact that they are the only renewable roofing material makes cedar shingles and shakes a true eco-material.
The main difference between shingles and shakes is that shingles typically have thinner butts than shakes, so they lie flatter for a more tailored appearance. Cedar shakes, with their thicker butts, create bolder shadow lines for a more rugged appearance.
Shingles have a reduced exposure, which results in a 3-ply roof system. Shakes, on the other hand, have a larger exposure and are a 2-ply roof system.
Tapersawn shakes are sawn on both sides for a semi-textured look with a defined shadow line. Also available are Hand-split & Resawn shakes, which feature a rough split exposed face with a sawn back for a unique rustic appearance.
'Premium' is the highest grade of shake available and are made from the very best defect-free, old-growth, vertical grain cedar. They are the ultimate in appearance and durability, produced by Waldun Forest Products – one of the most highly reputed manufacturers of cedar shingles and shakes.
Premium Grade Tapersawn Shakes are 18"/457mm in length with a butt thickness of 5/8"/16mm.
Waldun Yellow Cedar Shakes are sold in bundles. Each bundle of Premium Tapersawn shakes covers up to 1.86 m2 of roof area. In vertical cladding applications where the maximum exposure is increased, one bundle will cover up to 2.03 m2 for single coursing, or 3.34 m2 for double coursing (on top of an underlayer of under coursing grade shingles).
Bundles contain shingles of random widths, with the minimum being 89mm.
Certi-Sawn® is your assurance of quality. Yellow Cedar shakes bearing the Certi-Sawn trademark are inspected by legitimate third-party agencies, accredited by the Cedar Shake & Shingle Bureau. The term 'Blue Label' is a registered trademark of the Cedar Shake & Shingle Bureau trade association, which has over 250 member companies. Be aware that just because a supplier puts a label with a blue colour on its bundles does not mean that it's 'on-grade' or third party inspected.
If left in their natural state, cedar shakes will gradually weather to an attractive silver grey. Typically, this change will take effect after a 6 – 9-month period. A finish may be applied to maintain or enhance the natural colour or, if preferred, change the colour entirely. Cedar shakes will readily accept a penetrating stain such as Sansin SDF, which can be supplied separately for site application.
Yellow Cedar heartwood has a proven life expectancy of 60 + years due to the presence of natural oils that act as preservatives to help the wood resist decay.
Yellow Cedar has twice the stability of the most commonly available wood species. It does not excessively shrink, swell or warp through changes in moisture or temperature. Over time it will tend to lie flat, stay straight and hold fasteners tightly.
Once nailed in position, cedar shakes have an outstanding level of rigidity. The extra strength gained from the 2 or 3 -ply overlapping method of installation makes them highly resistant to extreme weather such as wind-driven snow and rain, ice, sun, and even hurricane-force winds. Cedar shakes are 'Uplift tested' to withstand wind speeds of up to 173mph.
Yellow Cedar shakes breathe, providing an extra degree of ventilation.
Cedar shakes use a low level of energy to produce and transport, and their production emits a low level of pollution compared to other materials.
Wood offers a high degree of thermal insulation compared to other materials, with 413 times the thermal resistance (R-value) of steel, 2,000 times that of aluminium, and eight times that of concrete. Yellow Cedar offers a high degree of thermal insulation, reducing the amount of energy needed to heat and cool buildings.
The fact that cedar shakes are up to one-tenth of the weight of traditional roofing materials means that savings can be made in the supporting structure. Their low weight also makes shakes easy to transport and handle.
Yellow Cedar shakes are lightweight, easy to handle, and easy to cut and work with standard tools. They are quick and easy to install – each shake is nailed to a batten using two nails.
Yellow Cedar used to produce shakes is a renewable and sustainable resource.
When trees are harvested, new trees are planted. These growing trees emit oxygen, absorb carbon dioxide, clean the air, and create a healthier environment.
Yellow Cedar shakes are renewable; sustainable; their manufacturing produces low emissions and no wastage; they contribute to providing energy-efficient buildings and are recyclable. This makes them a truly 'green' building material.
A good part of cedar shake and shingle wood fibre supply comes from salvage logging. The salvage logging process involves harvesting sections of logs that would otherwise be left on the forest floor as they are unusable for other forestry business operations. As cedar is naturally decay-resistant, this salvage fibre is in pristine condition and allows the industry to make full use of a valuable natural resource.
Made from exceptional old-growth Yellow Cedar heartwood, the quality of Waldun Premium Tapersawn shakes exceeds the official industry grading rules.
Waldun Premium Tapersawn shakes are made by Waldun Forest Products, a family company that dates back half a century and is today one of the largest and most respected names in the cedar shingle and shake industry.
The Waldun name is synonymous with quality. In 2012, Waldun shakes were chosen for the restoration of Philadelphia's Independence Hall - perhaps the most important historic building in the United States. It was here that both the Declaration of Independence and the US Constitution were debated and adopted.
Silva's relationship with Waldun goes back over 15 years. Our partnership with this leading manufacturer enables us to offer our customers the most comprehensive range and extensive stockholding of cedar shakes and shingles in Europe.
In addition to shakes, Silva also provides pre-formed shake hip and ridge units, battens, Tyvek® breathable membrane, stainless steel nails, and a wide range of finishes and cleaning products. All you need to complete the job.
