SR Timber

Almost 11,000 linear metres of SR Timbers graded PREMIUM GOLD® roofing batten has been used to support the roofing slates in this new rural development by Hereward Homes in Bisbrooke, Rutland, completed in October 2024.The development comprises four new homes, featuring barn-style designs that reflect the site’s historic farmyard origins. With 2 five-bedroom and 2 four-bedroom homes, the development has been designed to reflect Rutland’s distinctive vernacular on the outside, but inside, they are light-filled living spaces finished to a high specification. Each dwelling features luxury kitchens and bathrooms, many en-suite bedrooms with walk in dressing rooms, and includes air-source heat pumps, car charging points, and electronic remote-controlled garage door access. Hereward Homes selected Sandall roofing, based in Bourne, as the specialist roofing contractor on the project. Their chosen roofing supplier was AccuRoof, part of SIG UK Roofing, who provided both SIGA 13s Slate and SR Timber PREMIUM GOLD® Roofing Batten to support it.SIG Roofing branch in Newark, which is closest to the site, delivered the 10,840 linear meters of SR Timber PREMIUM GOLD® Roofing Battens to site for the pitched roofing areas of the project. The batten meets the specifications outlined in BS 8417:2011+A1:2014 (preservation of timber) and is graded according to BS 5534:2014+A2:2018. Additionally, it is one of the few battens that has passed assessment by the Code for Construction Product Information (CCPI).The batten provided support for the 41,000 SIGA13S 500x250mm slates, which were used on the project. Sourced from Northern Spain the slates are 5mm in depth and are smooth dark blue/grey slate offering a rustic character. SIG Roofing also provided 160kg of copper nails, 587 Marley clay capped angle ridges and a dry ridge fixing pack, Fix-R GRP slate valleys and Klober slate vents to complete the job.

Almost 20,000 linear metres of SR Timbers graded PREMIUM GOLD® roofing batten has been used in a roof renovation of the Grade 11 listed West Bromwich Town Hall and Central Library completed in September 2024.This large-scale re-roofing project is part of a larger £7.5 million project to restore this historic civic building, increasing public usage and securing its future. The main contractor for the project was Morgan Sindall, which appointed NRA Roofing Limited as the specialist roofing contractor, responsible for removing and replacing the existing roof covering. A primary supplier involved in the project was AccuRoof, part of SIG UK Roofing, providing both SIGA Slate and SR Timber PREMIUM GOLD® Roofing Batten.SIG UK Roofing branch in Dudley, which is closest to the site, supplied the 19,800 linear meters of SR Timber PREMIUM GOLD® Roofing Battens for all the pitched roofing areas of the project. The traditional pitched roof was over 150 years old, and the project involved removing the existing slate and installing new materials. The SR Timber PREMIUM GOLD® batten meets the specifications outlined in BS 8417:2011+A1:2014 (preservation of timber) and is graded according to BS 5534:2014+A2:2018. Additionally, it is one of the few battens that has passed assessment by the Code for Construction Product Information (CCPI).The batten provided support for 44,000 SIGA 112S Spanish slates, which were used on the project, a like-for-like slate ideal for the heritage roof. NRA visited the quarry and factory in Spain to ensure that the processes, quality, and availability met the demands of such a large and prestigious project. The slates measured 500 x 250mm and had a thickness of 7mm. This specification was approved, and a total of 2,340 meters squared, were supplied through the same SIG Roofing Dudley branch, The SIGA 112S is a smooth, dark blue-grey slate that is suitable for a variety of roofing projects. Its resemblance to the slates produced in the Vale of Ffestiniog has earned the SIGA 112S approval from Snowdonia National Park, highlighting its versatility for heritage projects throughout the country. This slate meets the requirements of NHBC, conforms to BS EN 12326-1:2014 – T1/S1/W1, is the first natural roofing slate to pass the Code for Construction Product Information (CCPI) assessment, and is backed by a 75-year warranty. It is particularly advantageous for projects requiring large quantities of slate, especially in planning-sensitive areas or where the cost of Welsh slate is prohibitive.

An amazing project that features SR Timber’s stunning cedar shingles has been put forward for a prestigious roofing industry award.The owner of the Stable Complex in Hertfordshire specifically chose our western red cedar shingles as a fundamental part of the design after travelling through America and being spellbound by the natural aesthetics of shingles and how they weather over time.Cedar shingles were also specified for the project because the stables are set in a woodland area, and the architects who designed the buildings wanted to ensure that the structures blended perfectly within the natural surroundings.To us, it’s no surprise that western red cedar shingles are increasing in popularity, and here are a number of reasons why:The first is that they are truly renewable and sustainable and therefore make an ideal roofing solution for projects where environmental considerations are important (our suppliers have a policy to re-plant three trees for every one harvested within one year and to the exact species ratio of the trees that were harvested. PEFC Certified shingles are also available when full chain of custody is required). Because they have one of the lowest carbon footprints of any building product, they can also significantly contribute towards zero-carbon housing achievements.The second is that they are lightweight, are extremely durable and offer excellent natural insulation properties, with a value of K = 0.1067 W/M degrees C. That’s a very impressive figure.Thirdly, it’s all about the quality. There are a number of grades of western cedar shingle, but SR Timber exclusively favours Blue Label – the highest grade that is available, which complies with the strict standards set by the Cedar Shake and Shingle Bureau. Blue Label shingles originate from 100% heartwood, use 100% edge grain and are 100% clear.The final, and arguably most important, reason is the way they look and the fact that they weather so beautifully over the years and transform into a gorgeous shade of silvery grey. Given that they have a life expectancy in excess of 50 years (when treated with Tanalith ‘E’ preservative), they can be the showpiece of any building structure.Although they are still seen as something of a niche roofing product, the diversity of usage – such as the Stables Complex project – highlights why the popularity of western cedar shingles is on the increase, and we’re keeping our fingers crossed that this particular case study wins big at the awards.You can download our datasheet on SR Timber’s cedar shingles to see the technical details of the shingles and how-to specifications for installing them.

Over 7,000 linear metres of SR Timbers graded roofing batten was used on the Lucent project, a complex multi-material and award-winning roof located behind Piccadilly Lights in London W1. The mixed-use development near Piccadilly Circus in London's West End features one of the most complex roofs ever built in the capital. Spanning almost an entire city block, the project took over four years to complete. Fletcher Priest Architects designed the development, with Wates Group as the main contractor and E J Roberts as the specialist roofing contractor. The project involved the unification of thirteen different buildings, including several historic facades.AccuRoof, the specification arm of SIG Roofing, was tasked by Wates Group to create a complex folding roof that would fulfil the architects’ original design vision and meet the requirements of BREEAM Outstanding and the Gold WELL Building Standard. The chosen solution involved incorporating natural slate elements into the design while navigating strict environmental and fire safety regulations that prohibited the use of hot works or lead flashings.The solution, implemented by E J Roberts, a multi-disciplinary roofing contractor with over sixty years of experience, is a roof composed of three different roofing systems. Cwt-y-bugail Natural Slate covers most of the roof, elZinc Lava zinc is used for flashings, gutters, balcony edges, and cladding, and IKO Permatec Hot Melt inverted roof system is used for the flat roof areas, the 22 terraces, and behind the iconic lights.The Lucent W1 slate features a beautiful dark blue-grey Welsh Slate from the Cwt-y-bugail quarry in Ffestiniog, covering a total of 1450m2 and is designed to meet the requirements of BS 5534. The main roof areas are covered in 500x250mm slates in the heavier 7mm County grade, with a riven leading edge. This gives the roofscape a familiar, high-quality look, similar to that of historic buildings in the capital. All the slates are double nailed and hook-fixed, and bespoke snow guards eliminate any risk to pedestrians below.Some of the roof areas required a very low pitch of 15 degrees, which is outside the British Standard. AccuRoof collaborated with specialist manufacturer Permavent to integrate their Easy Slate system in these areas. The system incorporates a unique soaker between each slate, allowing natural slates to be installed at pitches as low as 12 degrees.Natural slate forms the largest part of the roof and all slate areas were specified to use fire retardant (FRT) batten to meet the project’s fire safety requirements. The original architects design intent stated the use of Aluminium Counter battens (A2 fire rated), but as this wasn’t a recommended install method by Welsh Slate, who recommended timber battens, AccuRoof were able to provide Euroclass B Fire Rated Timber Battens for the project, that the Architect approved. The substantial order was therefore awarded to SR Timber and fulfilled by SIG Roofing who supplied all the roofing materials for the project. It contained 3700 linear metres of BS 5534 graded 25mm x 50mm Fire Retardant Treated (FRT) batten and approximately a similar quantity of 50mm x 50mm counter batten specially produced and graded to BS 4978, also Fire Retardant Treated (FRT). The special order required SR Timber to supply its usual high-quality graded roofing batten, completed with an additional process. Instead of undergoing its usual water-based treatment to produce its trademarked Premium Gold batten, each piece is monitored for its moisture content and given a fire retardant treatment. The completed special order was then delivered to their customer SIG Roofing’s Kentish Town branch. The SIG Roofing branch held stock to allow easy call off from branch and it had an additional stock holding area closer to the site. All roofing materials had to be carefully craned on site, as part of a detailed logistics programme. The work was taking place in a busy area of the West End with limited access and two flagship retail stores that needed to remain open. Due to the tight schedule, all 28,000 roof slates were stored on top of the building for weeks before installation.“We were delighted to be able to supply our batten for this prestigious development. It is a testament to our reputation as a supplier of quality timber batten for the UK market. The additional FRT process is also something very few other batten suppliers now offer as it requires a graded batten that hits the correct moisture content to be even considered.” Said Shaun Revill, Trading Director at SR Timber.More details on this stunning project at https://accuroof.co.uk/article/lucent-w1-how-the-complex-roof-was-built/ Client: LandsecArchitect: Fletcher Priest ArchitectsMain Contractor: Wates GroupRoof design and supply: AccuRoof with SIGA Slate, SIG Zinc and Copper, SR Timber and SIG RoofingSpecialist Roofing Contractor: E J Roberts Roofing LtdProject Website: LucentW1
