John Brash is a leading manufacturer of Roofing Battens, Scaffold Boards, Timber Decking and the UK’s largest importer of Western Red Cedar Shingles. The family owned company was started back in 1905 and now has its fourth generation member of the Brash family, in charge.

John Brash is the only company in the UK where roofing battens are manufactured, treated and certified to BS 5534 at a UK location, under stringent UK regulations. This operation supports over 100 UK manufacturing jobs.

All timbers are legally and sustainably sourced and, as members of the Timber Trade Federation, they support the Responsible Purchasing Scheme. John Brash has both FSC and PEFC accreditation.

John Brash has Europe’s only dedicated Roofing Batten scanning line which includes a computer controlled dedicated laser and camera grading line, to produce battens graded to the performance requirements of BS5534:2014; all other suppliers into the UK Batten market rely on visual grading.


John Brash’s premier roofing & tiling batten and the first full pre-graded roofing batten available to the roofing industry. Recent changes to BS 5534 mean that grading on site is no longer an accepted practice.

JB-RED completely meets the NHBC requirements for fully graded roofing battens. Its distinctive red colour means that it is highly visible on site, therefore Local Authority Building Control, NHBC and other inspectors can see that high quality, pre-graded roofing battens have been used. All JB-RED has full chain of custody (FSC or PEFC) credentials.

Western Red Cedar Shingles

Western Red Cedar from John Brash are a truly renewable and sustainable roofing & cladding material, with one of the lowest carbon footprints of any widely used building product. They are light for transport but offer a high degree of thermal insulation. All John Brash Cedar Shingles & Shakes have PEFC Chain of Custody, to ensure both a legal and sustainable product.

John Brash only recommends the use of the premier No 1 Grade Blue Label Western Red Cedar Shingles & Shakes for roofing and cladding. The Blue Label grade ensures that all Shingles and Shakes are made from cedar that is 100% heartwood, 100% edge grain and 100% clear.

John Brash is a member of the Cedar Shake & Shingle Bureau.
