Roofing Round Up
UK Roofing Awards
The UK Roofing Awards, an industry-wide event that recognises and rewards outstanding workmanship and safety within the roofing industry, were held on the 11th May. Hosted by the National Federation of Roofing Contractors (NFRC) with SIG Roofing as headline sponsor, the competition covers the full spectrum of roofing disciplines with projects judged on a range of criteria from difficulty and aesthetics to problem solving and workmanship.
This year there was a new category ‘Local Hero’ (see below), which celebrates the charity work of contractors that often gets overlooked.
You can see all the winners at: www.nfrc.co.uk/uk-roofing-awards/
As well as celebrating roofing skill and workmanship, this year’s UK Roofing Awards also focussed on the great achievements of the roofing community that often go unheard. Headline sponsor, SIG Roofing and hosts NFRC introduced the new ‘Local Hero’ award to find our unsung heroes. Whether it was roofers raising money for charity, or giving up their spare time to work on community projects the award gave a chance to recognise these local heroes and their fantastic achievements.
This year’s inaugural winner winner is Lee Moran from Moran Roofing Specialists in Farnham, who was recognised for his years of fundraising for Tuckwell Hospice, which cares for terminally ill people, as well as other good causes. Having raised over £10,000 for the hospice so far, he also regularly takes on tough challenges to raise funds for charities. Lee is a perfect example of outstanding individuals who go the extra mile and he fully deserves the Local Hero award.
New online Wind Uplift Calculator Tool ‘clicks’ with users
Choosing the best roofing membrane – especially one to withstand damaging ‘underlay ballooning’ – can often be difficult. However, roofers can now make an informed decision with the new online Wind Uplift Calculator from DuPont™ Tyvek®.
The BS 5534:2014 Standard doesn’t just split the UK into 5 wind pressure zones, it also requires that the following factors are taken into consideration; roof height above sea level, site terrain, ceiling type and quality, slope and distance from any significant quantity of water.
By entering these factors into the Wind Uplift Calculator, roofers will get advice on the most appropriate membrane. It’s quick, and it’s easy.
The calculator is BRE tested and calibrated as accurate and in full compliance with all the requirements of BS 5534.

Compliant roofing batten at a glance
SR Timber’s brand new photography clearly shows the differences between batten that is compliant with BS 5534:2014 and other batten that doesn’t make the grade. The new images help highlight the key differences to watch out for, including size and position of knots, whether the batten is too distorted to use, wane and markings (all graded battens have four key pieces of information stamped on them; name of the producer, origin and/or species code, BS 5534, and basic size or sizes).

It’s all clearer with 20/20
As the trend for lower pitched roofing in the UK continues to grow, Wienerberger is shining a spotlight on the lowest single lap interlocking plain tile on the market. Its 20/20 roofing system, a flat interlocking plain clay tile, uses a unique design to reduce installation costs.
As well as its unique height, the system also aims to combat issues lower pitched roofing can experience during extreme weather. It does this by protecting the most vulnerable areas of the structure, such as the eaves, valleys, abutments, and roof window surrounds.
To support the system, Wienerberger has created an installation guide giving detailed information on how to fit 20/20. It’s a helpful tool for contractors to ensure the system works at its absolute best, and you can find it here: www.wienerberger.co.uk/product-search/20/20-
Dry Verge is best in class
It seems no matter where you go or who you speak to, Dry Verge accessories continue to be a hot topic.
Despite Russell Roof Tiles making Dry Verge accessories for more than 25 years, the team has noticed a big jump in sales of the product recently.
Maybe it is because of the improved standards (BS 8612) that came into force this year or just that everyone recognises that Russell’s Dry Verge product is the best in class.
To help the growing popularity, Russells have invested £85,000 to improve their Dry Verge accessories range by purchasing some amazing new machinery at their dedicated plastics factory. As a result, customers can further trust Russells, as they know they are receiving an even higher-quality product – which is great value as well!
TIL-R Nail Fuel Packs
TIL-R are always trying to find ways to help contractors save time and improve efficiency and with their Nail Fuel Packs that’s exactly what they’ve done.
Fully compliant with BS EN 14592:2008+A1:2012 the packs contain 34” clipped head strip nails in a variety of diameters and lengths, and also come with two or three universal gas fuel cells.
They are CE marked and available in electro galvanised or hot dipped galvanised zinc coatings and ring, screw or smooth finishes.
TIL-R nails are also included in SIG Roofing’s ONE Warranty, that covers pitched roofing product performance for 15 years.
Klober puts dry verge products to the test
Klober has been putting its two dry verge products, Uni-Click and Contract, through a variety of tests to show how both comply with the newly published British Standard BS 8612 Dry-fixed Ridge, Hip, Verge and Valley Systems for Slating and Tiling.
Under the watchful eye of technicians at the Monier Technical Centre, both verge types were put through their paces and the products more than met the Standard in both cases. In fact, in the mechanical resistance test the tile adjacent to the verge actually snapped while the verge remained firmly in place!

VELUX ACTIVE will be available from July 2018 – so watch out for more information coming soon.
TIL-R Copper and Aluminium Slate Nails
Another example of TIL-R helping contractors is their copper and aluminium nails for slate. These have been designed to meet all the requirements of BS 5534, which stipulates a minimum gauge of 3mm, a head size of 10mm minimum and a penetration into the batten of a minimum 20 to 22mm. TIL-R’s nails provide good penetration into batten without damage, and with a gauge of 35mm x 3mm and a 10mm head, they fit the bill perfectly.
Available in packs of 500 for convenience, the nails are suitable for slates from 4.5mm – 7mm thick, which means they are usable with most slates in England and Wales, so you don’t have to keep nails of different lengths. Textured rings also improve pull out resistance to make the job even easier.
Soudal’s Soudatherm Roof range features a number of products which make easy work of most roofing insulation and roofing surface applications. Products offer both traditional methods and newer technologies to help speed up the process. Soudatherm Roof 170 is a traditional liquid polyurethane adhesive with an easy pouring spout for easy application. Soudatherm Roof 250 & 330 use newer technologies in the form of a polyurethane foam adhesive which both bonds and also fills any small gaps that there may be. Available in small and bulk formats, the Soudatherm Roof range is ideal for bonding any roofing insulation, even vertically.
The benefits of Rivius
A product that prides itself on being completely unique to the market, Rivius is a roofing system that uses large format interlocking clay tiles with a riven surface and dressed edges to give the look and feel of slate. The Rivius system is deliberately designed to be cost-effective, and its cheaper rate is a key benefit for contractors. Benefiting from the natural properties of clay – long-lasting, sustainable and low maintenance – Rivius is not only aesthetically attractive, it is also environmentally and financially appealing too. The tile is part of Wienerberger’s wider New Generation range, which aims to create highly durable tiles that can be utilised across a variety of roofing projects.

On the Case
Roof refurbishment for historic Hurst Castle
In 2017, an extensive refurbishment of the roof of Hurst Castle in Milford-on-Sea was scheduled by English Heritage, part of a £1 million restoration project.
Significant asphalt repairs were made throughout the West Wing’s roof, while the roof on the East Wing was stripped and laid with 150 tonnes of sand and cement screed under 300 tonnes of IKO Permaphalt mastic asphalt. All parties – including Heritage Building and Conservation (South) Ltd, Infallible Systems and IKO PLC – had to work closely together to ensure like-for-like replacements of the original materials.
Most of the work was carried out on a steep fall of 20%. As numerous alterations have been made to the castle since it was built in the 16th century, plans had to be continually adjusted, as variations in the details and materials were uncovered. The castle remained open to visitors throughout, and due to the exposed nature of the site, weather conditions were a constant obstacle – particularly as it was only accessible via ferry or a 1.5 mile gravel spit!
Despite the challenges the works were completed safely, on time and to a very high standard. Hurst Castle is now back to its former glory.
Easy-to-fix pantiles deliver rustic charm for historic barn conversions
Marley Eternit’s Lincoln interlocking pantiles have been used for a double barn conversion project in the Teversal conservation area. The innovative tiles were chosen as an easy-to-fix way of achieving the traditional pantile aesthetic required by local planning.
Set in the historic village of Teversal in Nottinghamshire, Dovecote and Teversal Barns are an important part of the area’s agricultural heritage. Although the original pantiles had been retained when the barns were converted to residential use, over time the historic roofs had fallen into a state of disrepair. Adrian Smith Builders was appointed to complete a full roof refurbishment on both barns.
Adrian Smith explains: “Teversal village is in a conservation area, so roofs are either Welsh Slate or traditional red pantiles. However, traditional pantiles are really cumbersome to install, so the Lincoln is a welcome alternative and one we would definitely use again. We couldn’t believe how much quicker and easier to install the tiles were, yet the finished roof still has the beautiful curves and rustic charm of a traditional pantile roof.”
As simple to install as a concrete roof tile, the Lincoln can be used at an extremely low minimum roof pitch of just 17.5o and is available in Rustic or Natural Red.
Exposed estate weathers storms with Redland specification
One of the highest housing estates in the UK has survived 100mph+ winds without any damage to the roofing after employing SpecMaster, the free-of-charge roof specification service offered by Redland. The largest public sector housing venture in Wales when built in the late 1960s, the hill-top Penrhys estate is now maintained and operated by Trivallis, one of Wales’ largest registered social landlords.
“The monopitch roof can double the wind speed, and the way the properties are positioned there are vortices between the blocks of flats, which makes the wind even faster”, explains Lee Tapper, Trivallis Surveyor and Clerk of Works.
As the roofs were coming to the end of their design life, Trivallis brought in SpecMaster. Altogether 15 two-storey blocks of flats were re-roofed with Mini Stonewold Tudor Brown and Slate Grey interlocking concrete slates with a very tight fixing specification stipulating that the first seven courses were both nailed and fixed.
Developed for architects and professional specifiers, the SpecMaster specification covers every detail of the complete roof from the tiling, performance specification and British Standards compliance to best practice for flashings and carpentry.
Stopsley High School of ROCKWOOL
Stopsley High School, a mixed Comprehensive and Community Specialist Sports College located in Luton, received funding from the Government to allow for building improvements.
Main contractor, Interserve worked with sub-contractor, Briggs Amasco, Arup and SIG Roofing, to deliver a modern, purpose-built and well-insulated school building. The brief was to provide pupils with a thermally efficient and acoustically sound environment that is conducive to learning.
Briggs Amasco needed to achieve a thermal performance of 0.15 W/m2K in the school and meet the acoustic performance requirements of BB93 in order to achieve a target noise reduction of Rw44Db. Alongside this, they required a roofing solution that could control the noise generated in high traffic areas, such as the sports hall and music rooms.
ROCKWOOL insulation products, including HARDROCK® Multi-Fix (DD) Underlay and HARDROCK® Multi-Fix (DD) were installed on the flat roof of the newly built building, delivering a comprehensive thermal, sound and fire safe solution suitable for this type of multi-purpose application. ROCKWOOL has given the school a roofing solution that is thermally efficient, provides great acoustic and fire properties, while enabling effective teaching and learning with a high level of fire protection.
Cembrit slates turn heads in Dursley
Easy to install Cembrit Moorland Blue/Black slates have been used on phase two of St Modwen’s new build housing development in Dursley, Gloucestershire. Chosen for their attractive appearance, and following a successful phase one, the Moorlands were once again supplied by Willis Westcott and installed by Mcdonnell-Price, a local roofing contractor.
The properties at Littlecombe have been built using a blend of modern and traditional materials which gives the development a timeless appeal. The Moorland Blue/Black slates provide a contrast with the light coloured fascia materials and surrounding greenery. This clean appearance is enhanced by the first class installation work carried out by McDonnell-Price across the development, which features roofs with Velux windows and many vents and valleys, alongside several pitch variants of between 30 and 45 degrees. Brandon McDonnell, of McDonnell-Price is very satisfied with the end result:
“I’m pleased with the way the project came together – everything just seemed to click into place. We like Cembrit’s Moorland slates and with a project like this, one that involves a lot of detail, it was good to have a slate that is lightweight, as well as easy to cut and fix. I also like the way dark Blue/Black colour stands out and nicely defines the roof lines against the surroundings.”
Working at height scheme
Falls from height are the most common cause of fatal injury in the workplace – with just under half happening within the construction sector.
Part of this is down to a lack of control of who carries out works at height, the training required, and verification of relevant skills, knowledge and experience.
Back in January, the All Party Parliamentary Group (APPG) for Working at Height launched an inquiry into injuries and fatalities caused by falls from height and falling objects. It agreed that while the current Work at Height Regulations (2005) are suitable, clearly more can be done in terms of compliance and best practice.
Supporting this initiative, the NFRC believe that all works must first be planned, the right equipment used, and only competent contractors employed.
NFRC in conjunction with the CITB, have launched plans for an accredited roofing scheme, which will place safe working practices at its core, ensuring an accredited workforce have the necessary skills to carry out work at height.
Schemes like this will help clients make informed decisions when choosing a contractor in the same way that most homeowners will get Gas Safe-accredited plumbers to install and service their boilers.
To torch, or not to torch?
Icopal has produced new guidance for roofing contractors which sets down when roofing membranes can be torch applied, when flame-free solutions are needed and who is responsible for assessing risks and working safely.
The six-page document, TorchSafeTM Detailing, Guidance Document for Reinforced Bitumen Waterproofing, has been produced to support the National Federation of Roofing Contractors’ (NFRC’s) Safe2Torch Campaign. Icopal is a Safe2Torch-registered manufacturer which means that it has signed up to commitments including highlighting and reporting specifications that don’t conform, ensuring proper training and checking that supervisors have completed a Safe2Torch checklist before work begins.
NFRC launched its Safe2Torch campaign in 2017, following a number of high-profile fires, such as the one at Selsey Academy, which destroyed a large part of a secondary school in West Sussex in August 2016. Roofers were working on a Sunday afternoon putting finishing touches to the roof when the incident took place, resulting in over £60m worth of damage.
Often, at-risk areas are not immediately apparent, because flammable materials are hidden within existing features around the roof. Icopal’s guide highlights potentially vulnerable features such as roof lanterns, timber upstands, open perpends or pitched roof abutments and explains how they should be treated.
Icopal’s thermically activated (TA) products offer a safe solution because they are applied using hot air welders that give zero risk of a fire.

Ventilate when you insulate
When upgrading the levels of insulation in a roof space, it is important to ensure that the existing levels of roof ventilation are adequate.
Problems frequently arise after adding or increasing the levels of roof insulation. This is particularly true during prolonged cold spells, where high levels of condensation build-up in cold roof spaces causing harmful mildew, mould and timber decay. The accumulation of condensation can go unnoticed for long periods, and by the time it has been discovered, the damage has been done.
The passage of moisture laden air into the roof space can be reduced by sealing the ceiling penetrations created by pipework, plumbing, wiring and loft access doors, and wall to ceiling junctions. It is, however, almost impossible to achieve a good and effective seal that will stand the test of time.
Increases in insulation thickness in lofts and attics causes less heat being transferred into the roof space resulting in the air temperature, roof timbers, roofing underlays etc. all becoming much colder. This dramatically increases the risk of condensation where roof ventilation is inadequate. Where there is sufficient ventilation, it’s important to ensure any additional insulation doesn’t block the ventilation openings.
Buying quality doesn’t cost, it pays
With years of experience in your trade to become highly skilled, you know that your work won’t let you down, so neither should the materials you use. The installation and maintenance of roofing are amongst the most critical elements of the performance of our buildings. Excellence in skills of the trade must be matched with the performance of the products chosen for the project.
For roofing contractors, failure or compromised performance in materials can lead to a host of issues. These range from downtime on site, additional costs in time and materials, bottlenecks with other projects, and crucially a tarnished reputation, to loss of referrals and future business.
The A. Proctor Group developed Roofshield to meet the requirements of cold-pitched roof construction, to ensure contractors are guaranteed the highest quality, providing a pitched roof underlay, which is both air and vapour permeable.
In line with guidelines by the NHBC, independently certified air and vapour permeable underlays can be used without additional ridge ventilation in cold roofs. The use of Roofshield leads to savings in labour and material costs, due to no VCL being required. Its high-performance air permeability means that the roof space has similar air changes to that of a roof using traditional eaves/ridge ventilation.
Low odour liquid keeps Vue Cinema open
When a Vue Cinema on the outskirts of Doncaster needed a section of the asphalt flat roof refurbished, a low odour solution was required that would allow the building to stay open to the public throughout installation.
The 750m² roof, located in the centre of the cinema above a stair and lift core and projection rooms – was covered with a lot of mounted plant, equipment and trunking making it too disruptive and noisy to take up and replace the existing asphalt. A liquid cold-applied waterproofing product was considered ideal to avoid the need for complex edge detailing associated with single ply or bitumen products around the plant.
With these concerns in mind, Specification Manager Cameron MacAndrew, from SIG Design Technology chose to recommend Hydrostop AH-25, a wet-on-wet cold applied liquid waterproofing system that contains no solvents or isocyanates, with a very low VOC content.
The Hydrostop AH-25 liquid roofing system is now even quicker to install. The system can be applied directly to the face of the specified insulation board and only requires the application of a 100mm wide self-adhesive jointing tape to the joints of the insulation. This avoids having to apply an entire bitumen carrier membrane over the insulation as some other liquid systems do.

Aluminium gutters: maintenance misconceptions
When choosing a rainwater system for a property, there are several factors to consider. Here, we take a look at aluminium systems, the benefits and some of the common misconceptions.
Aluminium is a metal – won’t it corrode?
High quality, marine-grade aluminium naturally generates a protective oxide coating, which prevents it from corroding. This means the system will not require any maintenance across its 50-year life cycle, aside from periodic aesthetic cleaning. This will reduce lifetime costs, as the need for repair and replacement is significantly lower than other materials.
Aluminium is so light, it can’t be very robust?
Aluminium has a superior strength to weight ratio. This also makes it much easier to install, as the gutters can be easily carried and handled by the contractor.
Aluminium systems still need repainting?
Marley Alutec use a fade resistant architectural grade polyester powder coat paint finish specifically designed for external use, which provides a 35-year decorative life expectancy and will fade at a barely discernible rate.
There are several factors to consider when choosing the correct rainwater system for a property. Due to its low weight, durability and lack of required maintenance, aluminium is the ideal rainwater system solution for a wide range of properties, from new build to heritage conservation.
Out and About
More than Goodenough!
As we go to press Ian Goodenough, the SIG Roofing Divisional Sales Development Manager for the South, is hoping to have crossed the finishing line of the 2018 Cape Wrath Ultra – a once in a lifetime 8-day expedition race through 400km of the Scottish Highlands.
Those of you that know Ian well, will know he regularly runs marathons (26m) and Ultra Marathons (50-100m) – however the Cape Wrath Ultra was his first endurance multiday event.
It is ultimately a running race – normally, Ian would run an off-road marathon in 3 ½ hours, however due to the terrain in the Scottish Highlands it took him 5-6 hours to cover the same distance. His days began at 5:30am for breakfast before heading out into the wilderness to tackle miles of peat bog, river crossings and mountain passes.
He knew it wouldn’t be an easy challenge!
This is why Ian wanted to dedicate this race and any funds he raises to Prostate Cancer UK and a good friend he has recently seen effected by this illness. Prostate Cancer UK has a simple ambition – to stop men dying from prostate cancer.
For his efforts, Ian was rewarded every night, with a hearty vegetarian meal, a wash in the nearest river and tent made for eight!
Anyone that would like to support Ian can still make a donation – no matter how small or big to Prostate Cancer UK by visiting the following link:
Well done Ian from all your colleagues at SIG Roofing!
