Rustic, textured Western Red Cedar Shakes for the ultimate in character

With a thicker butt and longer length than cedar shingles, Certi- split™ cedar shakes offer a rustic, rough look full of character due to being Hand split when manufactured.

They differ from shingles in two ways; at 610mm they are longer and at 16mm the butts are much thicker.

Hand split shakes are produced by splitting cedar blocks with a hyrdaulically powered knife into straight boards, or blanks. The blanks are then sawn from corner to corner, producing two tapered shakes, each with a natural split face and a sawn back.

Cedar Shake roofs can be seen all over the US and Canada but are far less common in the UK. They are incredibly durable and are able to withstand extreme weather conditions. Cedar Shake roofs also provide excellent insulation and as a result are increasingly being specified by architects for energy efficient buildings. As far as we are aware, we are the only importer offering this product in the UK. We are confident that if you like the look of Cedar shingles you will love the look of Cedar shakes.

Certi-Label™ Confidence

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 & Shakes. 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 in a blue colour on its bundles does not mean that it’s on grade or third party inspected. Certigrade Western Red Cedar Shingles & Shakes are inspected by legitimate, third party agencies, accredited by the Cedar Shake & Shingle Bureau. 

Silva Timber are the only member of the Cedar Shake & Shingle Bureau outside of North America. The Bureau monitors and inspects member mills to ensure product quality, grading rules and consistency of Certi-Label cedar shingles and shakes are maintained.

Approximated Nails usage guide - 1 kilo of 2.65 x 50mm Stainless Steel Annular Ringshank Nails will be required to fix 4 bundles of shingles.

Recommended use - A premium option for a wide range of uses, particularly main building roofs and walls where a handsplit, rustic character is desired. 

Length: 24" (610mm) Width: 4" (100mm) minimum, 14".

Batten Spacing

Space battens to coincide with the weather exposure. Spacing between adjacent shingles (joints) should be a minimum of 9mm and a maximum of 16mm.

Joints in any one course should be separated not less than 38mm from joints in adjacent courses and in any three courses, no two joints should be in direct alignment.

Coverage Guide

When working with timber it should be expected that although ‘on-grade’, occasional boards may have minor imperfections that will require ‘working’ if you wish to eliminate. Examples include raised grain, small splits, minor handling marks, sticker marks etc – all of which can easily be remedied by trimming, gluing or sanding. In most cases imperfections can be removed with very little effort, and the small amount of off cuts generated as a result will be absorbed in the normal cutting and selection allowance.

Western Red Cedar is the ultimate green building material. It is legally, responsibly and sustainably harvested in the publicly managed forests of British Columbia, Canada. Less than 1% of standing timber is harvested each year.

For each tree harvested, three are replanted to ensure the forests will exist in perpetuity. Western Red Cedar has a low impact on the environment throughout its life cycle. It requires significantly less energy to produce than man-made alternatives and is bio-degradable.
