Rainbow alliance on roofing battens

Red, blue, green, gold: roofing battens are a colourful lot. Whatever colour they come in, producers and merchants are allied in the view that it’s irrelevant to product performance as defined by BS5534.

Questioning your customer about their proposed use of ‘battening’, and whether they are working on a site which comes under one of the building or roofing trade associations, is the best place to start, says Gary Froggatt,

Divisional Manager and Forest Products Buyer for merchants: “We take time to have the conversation with the customer to determine which product they require, along with the specifics for each job.  As a generalisation, for roofers working on NHBC, NFRC and FMB member building sites, a fully-graded roof batten is required – one that’s stamped as meeting BS 5534, like our AFP5534.  The reason our product is dyed blue is to distinguish it as meeting the necessary standard: it’s a colour commonly used by Nordic and Baltic suppliers. But it’s the BS5534 grading stamp, not the colour, that’s important.”

The breadth of northern European countries able to supply the roofing batten market has expanded over the years, says Lee Johnson, Director at bulk importers Evans Bellhouse: “Latvian mills have vastly improved their quality in the past 15 years through major investment and are now producing roofing batten material that’s as good as Swedish. They’re also reliable: shipments arrive on time and there’s good availability. Most have adopted the BS5534 standard for battens, which is now a requirement on all NHBC new-builds.”

“Beyond roofing batten colours, there are persistent anecdotes about which section of a log makes the best roofing batten, and whether material should be kiln-dried,” Shaun Revill continues. “Independent wood science expertise has firmly stated that both of these are myths. If the grading system has been followed properly, including fundamental points such as sizes and positions of knots and slope of grain, the original log section and processing path are immaterial to quality. SR Timber’s Premium Gold battens are treated with Vacsol and are independently quality-tested by BM TRADA, carrying their Q-mark certification.”

Merchants may need to look at their product descriptions to avoid any customer misconceptions when it comes to suitability, advises the Timber Trade Federation.

“From the builders’ merchant’s perspective, risk management is a key issue where roofing battens are concerned,” says Nick Boulton, TTF’s Head of Technical & Trade. “The TTF’s advice to members is that products must not be described for sale as roofing battens, tiling battens or slatings unless they are marked as adhering to BS5534. Anything other than a BS5534 batten is simply a piece of sawn and treated timber.

“Only battens which have been graded by the manufacturer according to the full requirements of Annex D of the Standard – which covers knot size, frequency, distortion, slope of grain etc – can be marked as BS5534, signifying compliance with the standard. All TTF members supplying BS5534 marked roofing battens participate in third party QA schemes to ensure the consistent quality of their battens and to give confidence to their customers. Throughout the professional roofing supply chain, right through to local authority building control, only fully-graded and marked BS5534 battens are acceptable,” TTF’s Nick Boulton affirms.
