The 2020s begin

Joining the roofing industry after careers in teaching and the finance, Garry Lawrence articulates the many challenges and opportunities he sees in the sector (page 13).

As Graham mentions in his CEO update overleaf, your RANZ Executive are passionate about developing RANZ and the industry for all you good people, and are set to step us up and respond well.

Destined for our RANZ Member Toolkit online are some new article resources for you in this issue of Roof Link, including a technical on guttering (page 28), training bonds in employment law (page 27), fire safety on the job (page 35) and compliance paperwork and reports (page 22). Hopefully, you’ll find these articles useful in the day-to-day running of your business.

Kia ora tātou, From what I’ve heard, it’s been a busy start to 2020 for most of us. Diversity is a hot topic in construction recruitment and RANZ is faring well through its support for NZ Women in Roofing (NZWiR), which, by all accounts, is thriving – and they’ve now completed their first charity re-roof project (page 17), in conjunction with Habitat for Humanity.

President

In this issue we also take a look at the use of drone technology in roofing, via hearing about a RANZ member's introduction to it and the adaptation of the new tool into their operations (page 31).

And if you’re after some inspiration for entering this new decade, turn to page 8, where Topline have ‘topped the cake’ with a warm roof on an innovative commercial build that has been receiving both national and global attention and accolades. We’ll be hearing much more about warm roof systems at annual conference in Wellington, amongst a myriad of other key interest areas (June 10th - AGM, 11 & 12 – for your diaries).

Into the 2020s - let’s get it. Kia kaha (stay strong).

FROM THE CEO

CEO Autumn 2020 We are all back into it, well and truly, for the start of a new decade. The RANZ Executive is certainly looking to the future and is hard at work as we evolve our strategic direction.

what problem is that we are trying to solve here’. My brain is going, ‘wouldn’t it be better to prevent the problem from happening in the first place?’ This mind-set needs to change.

By the time you read this, the Executive will have met to continue the review and renewing of our Strategic Plan goals. Our approach is what we should all do when we plan. Develop your plan and then check to make sure it is relevant, measurable, achievable and time bound.

Likewise, the industry’s mind-set needs to change on risk allocation. There will always be risk. If you want to avoid risk, don’t get out of bed in the morning. We can mitigate much of this risk by changing the mind-set or focus, if you like. Your focus should always be on the best outcome for the customer. This needs a whole-of-industry approach. Yes, the majority of jobs are done well, but there are those out there who take the ‘just get it done and get out of here’ approach, and that needs to change. These are the same people that argue about the ‘poor outcome’ instead of doing it right to begin with. To my point in the previous paragraph – prevent the problem from occurring in the first place!

The goal of a Roofing School is still there and meets the four points above. Our previous goal around the brand and the perception of roofing is relevant. As you can’t easily put a definitive measure on brand, then how do you know when you have achieved your goal?

The third goal of all roofing work to be Restricted Building Work (RBW) is relevant and measurable. However, its achievement is in the hands of the government. We have lobbied and submitted on our position to MBIE. Ultimately, they decide if we achieve our goal. If we don’t achieve this one, we will continue to lobby for change. We will keep you informed as we evolve the new plan.

A position I am seeing more and more when I deal with those in officialdom is that they take a strange view of their roles. On more than one occasion I have been told, ‘we need to look at

understand. If the focus had been on the customer… just saying.

When Stephanie gave me the Rooflink flat plan (suggested layout) I reflected on the amount of change going on. Articles on using drones to survey jobs, members whom have established a model that they have available as a franchise opportunity, and the work of Women in Roofing all shows me this industry is going places.

Executive member, Paul Stanley Boden has written a great article on heat sources and safety. We are well aware of the significant consequences of a fire on a building site.

Some of us older roofers can tell stories of fire incidents on site. Read what Paul has written – there is safe and great advice in this article.

Keep it safe out there.

Graham.

To illustrate this, I have been recently working through a complaint about a member. A consultant was used to establish the good, the bad and the ugly. It was mostly good, but it took the member several attempts to rectify the problems. The problems stemmed from the member not having his first-choice contractor available to do the job, so thought that this justified some of the problems that ensued, and that the customer should

FROM THE ROOFTOPS

Generous donation Tarata, a rural Taranaki community of just 70 families, located 18km inland from Inglewood, had a problem: The roof of their local hall, the heart of their community, was leaking and had been for over 20 years. So, two years ago, a dedicated committee swung into action and through their efforts raised $25k. However, that was still way short of the estimated $60k needed for a new roof.

That’s when Paul Ross at Roofing Industries and Steve Haines at PCC became involved, impressed by the way this small, rural community had come together and worked so hard to raise the dollars needed.

While continuously being approached to donate product, both PCC (ColorCote) and Roofing Industries judged the efforts of this small community to be exceptional, and to this end, PCC donated coil and Roofing Industries Central Ltd roll-formed the New Denim Blue Zinacore True Oak Corrugate product for the roof, colour-matched to the material used on their church roof.

Shake it up Cooke Roofing recently completed this roof in Te Kuiti, removing the old wooden shake shingles and replacing them with Metrotile Shake, in Coffee Brown. The client wanted to keep the steeple look, which, Catherine Cooke says took a lot of technical thought to work out how to keep the gap between the roof and steeple weathertight and bird proof. The end result looks awesome. What a cool project to be involved in.

Roofman acquisition The acquisition and integration of Roofman Tauranga into the Roofing Industries Group of Companies has been viewed as a positive and strategic decision with synergies providing significant benefits to customers.

Gold for Aspect Last year, Auckland-based Aspect Roofing had six clients that had houses in the Auckland House of the Year competition, one of which, in association with Cashmore Construction, went onto win Gold in the Regional Auckland $1-$1.5 Million category and reached Gold Reserve status nationally, which puts it in the top 100 homes in NZ.

All existing staff have been retained at their Tauranga or Mount Maunganui branches, with both locations remaining open for business, thereby ensuring customers have ready access to a significant range of innovative and market leading roofing, cladding and ancillary products across the Western Bay of Plenty. Roofing Industries management and staff have extended a warm welcome to Roofman’s customers, staff and suppliers into the Roofing Industries Group.

Facelift for Trust Arena Professional Roofing Ltd have been nominated as the subcontractor to reclad the façade of Trust Arena – West Auckland’s multi-purpose event and entertainment facility which hosts a broad range of events including conventions, trade shows, music concerts and local, national and international sporting events. The new facelift will feature aluminium Euramax cladding to give this distinctively shaped building a new wow factor.

Beautiful tile, lovely location

Ampelite prize draw

Set in a glorious landscape out in the farmlands of Matamata, the roof on this house was recently completed

by Stone Roofing Ltd, installed as subcontractors for Westgate Roofing Ltd. The 370sqm of roof took the five-member team from Stone Roofing more or less 1.5 days to complete – and in the rain.

Ampelite’s Harley Davidson promotion was drawn on Wednesday the 5th of February 2020.

Graham Moor and Kerry Andrew (Ampelite CEO) met at the at RANZ’s HQ in Albany and, from the large number entries received, Contour Roofing from Nelson was drawn as this year’s winner. Congratulations goes to Contour Roofing, who will be flown up to Auckland to be presented with their new Harley-Davidson XL1200XS Forty-Eight Special motorcycle, valued at $20,000.00 (RRP), plus a voucher for genuine Harley-Davidson motorcycle accessories to the value of $2,000.00.

Ampelite would like to thank all of those who entered their Harley Davidson Promotion and invite you all to try again next time.

Liz Watson, from Stone Roofing, says the Teak Textured Colortile from Gerard Roofs was an “astonishingly beautiful style of metal tile”. Thankfully, she says it was also textured, which made it a lot easier to carry on in the rain. "We plan out the joins so it looks 'seamless' from a distance too. We're really happy with it."

Maxsafe safety competition Maxsafe have another $1500 voucher up for grabs. Entries are open to all RANZ members. All you need to do is send a photo and/or a brief outline of an example of your team’s good safety practice to editor@ranz.co.nz by 30 April 2020. Congratulations to last quarter's winner: Diane Beazley, apprentice roofer, Project Unite Ltd.

FEATURE PROJECT

Designed for the future The B:HIVE on Auckland’s North Shore is a unique, future-focused building that reflects the changing nature of the workplace environment.

Topline Roofing installed its warm roof.

BY JENNY BAIN

The Business Hive, also known as the B:HIVE, is designed by Australian architects BVN in conjunction with Jasmax to incorporate green technology and SMART building practices including provision of a warm roof on the five-level building.

Leighs Construction was the main contractor. The development at Smales Farm in Taharoto Road, Takapuna, received international recognition at the World Architecture Festival for its “exemplary sustainable and flexible workplace”.

Autumn 2020 • Issue 92

B:HIVE captures the latest thinking around workplace and urban design, providing activity-based working: flexible, premium open-plan office spaces offering both dedicated and shared spaces, suitable for a single person to work at a dedicated desk or with a choice of settings for different workplace activities. The flexible space in this light-filled building can be configured to cater for one person or up to 250 employees.

This agile design allows tenants to upsize their spaces when required, or to downsize them… basically giving personnel a choice of settings for conducting their business.

A warm roof system was specified and RANZ member Topline Roofing won the contract to supply and install the MSR warm roof system featuring 0.55 MagnaFlow by ColorCote from preferred supplier RoofLogic. Architects Jasmax also specified that the metal cladding for the building’s external walls should match the roof, so Topline supplied and installed approximately 1100m2 of 0.40g MagnaFlow Multirib cladding sheets in black. The company also supplied and installed guttering, cladding to internal stairwells and plant room

and flashing for the large glass skylight – known as the Shroud – this massive glass feature pours light to all floors of the building.

A spectacular feature of the atrium is the vibrant orange spiral metal staircase winding its way upwards, linking the floors vertically, and looking down on a garden bed at floor level. Nearly 34 tonnes of steel went into the manufacture of this twisting staircase which, apart from drawing the five floors together, fits perfectly with the designer’s determination to create a “wellbeing” environment for those working in the B:HIVE. The ground floor space, known as Goodside, is a hospitality precinct leased to retail outlets and eateries. Customers in this area are able to combine items from different cafes, restaurants and bars and sit outdoors at long black tables. Tenants include Shake Out, Ripe Deli and Goodness Gracious.

Topline’s preferred supplier for the warm roof was RoofLogic, a system that provides excellent thermal and acoustic benefits.

Having installed it on other contracts, Topline

now has considerable experience with it. The new plumbers’ training building at Unitec features this warm roof system and Topline rates RoofLogic highly, especially as it exceeds recommended thermal rating requirements.

Another benefit is that once the liner sheet is laid, the working space beneath is watertight, allowing other trades to continue working so the time-saving factor also becomes relevant for the main contractor.

RoofLogic provided the new MSR roof system with 0.55 MagnaFlow by Colorcote, which provides an insulation board (PIR board) captured between a vapour control layer, an underlay and two layers (bottom and top) of metal trough-section 25m long roof sheets supplied by Roofing Industries. Warmth is trapped and retained under the roof while noise is minimised by the installation of acoustic board. Also included in the scope of works was the rooftop plant room cladding, complete with new 175mm box gutters featuring MagnaFlow by ColorCote, rainwater heads and downpipes. Mixed mode ventilation is provided via thermal chimneys in the façade, which draw air through the

five-level atrium of the building. These ventilators also required flashing detail work as well as other mechanical flashings on the site.

The Business Hive was a complex project that took three years to complete, and was built by the main contractor Leighs Construction.

At times during the period of Topline’s contract, there were 150-200 workers on site, so there were many trades to consider when it came to health and safety, site induction and daily toolbox meetings. Neil Gillespie, Topline’s director of sales and operations, project managed this job which, at its peak, employed eight Topline roofers.

Neil, the site manager and the QS regularly met to discuss the large number of variations to the main contract during the build process, and flexibility prevailed in the final design.

Changes in the design affected the penetrations in particular, with Neil, as project manager, having significant direct liaison with the architects. There were some site, weather and wind issues to navigate, along with storage of materials, especially continued on page 11

when a tropical cyclone blew through early in 2018, damaging and placing the on-site tower crane – pivotal for delivery of materials to the roof – out of action for three months.

The thermal rating benefits of warm roofing and its acoustic capability mean this system is where much of the industry is heading, says Neil.

“The Business Hive is a really exciting concept, giving tenants flexible working areas, and the building has a great vibe and a very positive feel about it. I see this approach to activitybased working being taken up by others in the future. We include some of this philosophy of flexible working in Topline, giving employees more choice in terms of specific areas of work type.

“There is no doubt in my mind that warm roofing is where this industry is heading; the concept has been widely specified by architects as they focus on designing more efficient Green Star projects throughout New Zealand.

“Another huge plus of this warm roof system is that it can also be installed over an existing roof so there’s no need to remove old roofing to have a warm roof providing a high R value rating going forward. A warm roof addresses the important factor of commercial buildings and residential homes being warm in the winter and cool in the summer months, keeping climate control costs down.

Along with receiving international recognition at the World Architecture Festival in December 2019, the B:HIVE also won local recognition last year with an interiors award from the New Zealand Institute of Architects.

It has been claimed that the B:HIVE is the biggest purpose-built, co-working facility in the Southern Hemisphere, able to accommodate configurations ranging from a single worker to a business with up to 250 employees.

MEMBER PROFILE

Leading from the top RANZ member Garry Lawrence of Garry Lawrence Roofing Ltd brings a fresh perspective on what it takes to survive and prosper in an industry that works hard to provide an essential service to the public, but where businesses encounter many barriers to progress.

BY JENNY BAIN

Today’s business environment can be a very challenging place to operate in, especially for the owners of small companies. This is particularly true for companies in the roofing sector where, for a variety of reasons, the industry is under significant stress. To run and grow a viable roofing company from a one-man band to become a sustainable operation is not easy in terms of time, expertise and cost.

education and banking sectors – is an ability to recognise talent in people and to harness that potential in a roofing context. It’s a skill which transfers well to the roofing sector when attracting the right people.

The business Garry started his business in 2009, focusing on property maintenance and building work, then roofing repairs followed by re-roofing work.

Having grown to a staff of five employees, the business model now uses self-employed contractors, hand-picked by Garry for the range of services the company provides.

Garry Lawrence Roofing Ltd, based in Greenlane, Auckland, takes on much of the work that other RANZ members may decline.

However, earning enough from these jobs to justify the time, health and safety costs, and risk of the leak repair being multi-sourced and requiring further work, is a constant challenge. The need to quote with sufficient margins to secure work to fund overhead costs is a perennial problem – many property owners are unwilling to pay for actual costs of providing quality roofing services. Garry does not compete on price and discourages approaches from those who want the best job for the lowest price.

At the helm, in addition to securing the work and overseeing the jobs, Garry manages accounts, health and safety, employment, business planning and profitability. As the firm moves into more complex contracts, former company owner and LBP builder David Donnelly and other builders such as BioBuild work with Garry to satisfy a growing call for upgrades involving the structures where maintenance and reroofing is required.

A skill that Garry brings to this venture – one acquired from lengthy service in the

matters on an 1890s villa in Hamilton Road, Herne Bay (see image above). The partial restoration of this building involved re-piling two sides of the house using professional house lifters, re-building the turret inside and out, restoring windows and an ornate Victorian coloured glass window which had blown out in a storm, installing a new water line for a new on-demand hot water cylinder installation, rebuilding the steps of an imposing Victorian front entrance, rebuilding chimney tops, replacing veranda roof framing, and partially re-roofing in like-for-like metal sheeting. LBP Dave was fully involved in this 15-month-long contract which successfully concluded in mid 2019.

RANZ membership Garry learns a lot from each and every job performed – “it keeps you sharp”, he says, and joining RANZ was a sound move as the company makes strides in the difficult market of restoration and re-roofing. “It’s important that we belong to a professional organisation and that we demonstrate to clients that we meet certain standards and are professional and proud of what we do,” he says. continued on page 14

MEMBER PROFILE

continued from page 13

Marketing Word of mouth has been by far the most beneficial marketing exercise: happy clients translate to more referrals and Garry is intending to build the business to having up to two years’ work on the books. The Grey Power magazine provided some early responses but recommendations from satisfied clients has been the cornerstone of the company’s growth. Good communication with clients, respecting them and making them feel involved in the process is Garry’s formula for good marketing. A new card system will be implemented soon – How did we do? so clients can give feedback on completed contracts. Public referrals from RANZ have also made a significant contribution.

Background Originally from Christchurch, Garry attended Canterbury University before embarking on a teaching career – mainly 10-14-year-olds. In those days a teaching stint in country schools was a requirement of the education department and Garry served as principal at two rural schools before coming to view teaching as a profession with insufficient rewards for him; many teachers were leaving the profession and Garry soon followed. For something completely different he joined the BNZ’s Investment Advisory Services in Christchurch and later set up his own company – Quadrant Capital Management Ltd. In 2000 Garry moved to Auckland where he became principal of a private training establishment (PTE) teaching English as a second language, growing the facility from 60 to 250 students over three years by applying marketing and business skills. He then became a marketing tutor at the Crown Institute of Studies teaching students doing the NZ Business Diploma. A debut into roofing may seem an unusual sideways career move but so much of what he learned in previous roles has enabled Garry to apply a range of skills to what is now required in his roofing business. Garry says he was also tired of wearing a suit and tie while working indoors on sunny days so decided to become self-employed in the building and now roofing industry.

What’s the attraction in roofing maintenance, re-roofing and restoration?

“It’s the interesting nature of the trade: to see the job look good and being able to admire it, knowing it is going to be a repair or a re-roof that lasts, and being able to complete work quickly so clients do not have to wait a year to finish. Then there are the intrinsic rewards – loving the responsibility of heading up a professional team of roofers, and delivering jobs to the highest standard.”

Autumn 2020 • Issue 92

How is the industry tracking?

“Not too well,” says Garry. The reasons include difficulties in attracting and retaining quality people. Successive governments have allowed unsustainable high net immigration levels to provide short-term economic and fiscal growth without considering the ability of the infrastructure to support these numbers. In a similar way, both small and large roofing businesses have had to assimilate steadily increasing regulatory and cost burdens without consideration of the resources required to fund the time, skill and cost impacts of these. Examples of these regulatory time, responsibility and financial burdens include the Health & Safety in Employment Act 2015 and payday tax filing. These may be necessary, but there is a definite cost for a business to incorporate and maintain them.

“In my view, tradespeople in the roofing business are in a Catch 22 situation whereby we have steadily increasing compliance costs

“Roofing is a high-risk industry and a high level of skill, expertise and hard-won experience is necessary to avoid the traps and build a successful operation." and time requirements relative to these, but are often unable to pass these costs fully on to clients because of the competitive quoting system we have to go with. Good jobs take time and this has a cost,” he says.

“The roofing industry appears to have a training deficit to adequately attend to these; it is costly to contract out these responsibilities so it is likely that small businesses in the industry will continue to decline. Mature roofers are leaving the industry due to health issues such as fibrosis and back pain from years spent on the tools.”

Any niggly issues?

Garry identifies significant health and safety business risks; there’s always the thought that a mistake by a contractor could have serious consequences for their health, life and one’s own financial viability. Too many tradespeople still have a cavalier approach to their health and safety obligations – like keeping up to date with Site Safe certificates etc.

“Roofing is a high-risk industry and a high level of skill, expertise and hard-won experience is necessary to avoid the traps and build a successful operation. The elephant in the room is climate change and global warming.

“My view is that anyone who denies this has their heads in the sand. We have had leaky homes before but looking ahead there may be further significant outbreaks of leaky homes from torrential wind-driven rain, tornadoes and tropical and sub-tropical cyclones with attendant extremely high winds. Existing roofs were neither designed nor constructed to withstand extreme weather events, so widespread damage to all types of roofs in the future is, in my view, a strong likelihood. Will the industry have the capacity to repair and rebuild roofing damage from these events?”

The bottom line is that trying to make a fair net profit in the range of 10 to 15 percent in an industry facing many problems is difficult, particularly where there is no paid roofing work on wet days unless one goes to the expense of shrink-wrapped buildings, says Garry.

Skill shortages?

“We are significantly impacted by these and do not appear to have an answer. Skilled trade shortages are partly due to the current government prioritising new house construction, attracting trades people away from the repair and maintenance side of the industry. The best people in the industry seem to be working for a large firm or are operating their own businesses. It is a case of always keeping an eye out for skilled and capable people and attracting them. This is an area where RANZ is doing some great work but it appears that successive governments do not regard building and roofing industry skill shortages as a high priority,” says Garry. “I no longer employ roofing staff due to the difficulty in locating skilled and experienced personnel, but also in retaining them in an industry known for a high rate of staff turnover – plus the fluctuating income that is part of the roofing industry.”

Is this industry on the right track when it comes to training and recruitment?

“Yes and no. We are on the right track with some good initiatives such as the LBP scheme and the NZ Certificate in Roofing but progress is too slow. I have yet to see any measurable outcomes in this area at grassroots level and I don’t believe the politicians have the will, nor do they see it as priority to address the current industry skill shortages. Maybe mature roofers could be grandfathered into LBP or senior roofer status so that these older and more experienced practitioners could play an important role in training and mentoring younger roofers instead of drifting off into retirement or working in home improvement stores.” * * RANZ currently has an open call out for potential Roofing Tutors - if you are interested in being supported to become a roofing tutor please email Graham on ceo@ranz.co.nz.

Garry Lawrence recently joined forces with main contractor BioBuild to give a block of eight apartments from the 1950s a new lease of life, fulfilling the client’s brief to extend the life of the building by providing high quality, stable and healthy homes for his tenants – and also keeping a piece of Auckland’s architectural history alive.

The low pitch skillion roof could have been problematic – at one stage TPO was considered as a replacement – but this building was in relatively good condition so Dimondek 400 from Dimond was the profile of choice, and the building has an improved R-value because of the improvements in the roof space.

The main aim of the project was to replace the metal roof, which had reached the end of its life. Removal allowed the roof space to be opened up by improving the framing elements, and the wiring for the apartments below was future proofed for heating and ventilation systems. Garry’s team improved the insulation, ventilation and roof paper, bringing the eight apartments up to Healthy Homes standard.

BioBuild seeks to create a positive impact in the build environment by providing skills, knowledge and experience to offer eco-friendly and sustainable choices in construction. The company grew out of Alan Drayton Builders Ltd, established in 1986, when there was increasing awareness of toxic practices and materials used in construction.

Insulation was installed with a 20mm gap to the roof paper to allow any moisture to dry, and a waterproof seal along the edge of the building now prevents condensation running down the underside of the soffit and into the roof space.

The company first learned about sustainable, healthy and harmonious building options through the Building Biology and Ecology Institute of New Zealand (BBE), and in 1990 principal Alan was the first student in New Zealand to complete the BBE course in bio-harmonic building.

WOMEN IN ROOFING

Foreword from RANZ editor, Stephanie Fill: In the tradition of many kind-hearted, generous members before them, the Hamilton branch of NZ Women in Roofing gifted a charity re-roof to their local community. What occurred to me, as a distinction with this project, was the collaboration that it required to coordinate amongst professionals from various businesses on an unpaid project, completed in downtime. Frankly, it was sophisticated and inspiring.

I couldn’t pass up the offer extended to me by our very own Tradeswoman of the Year, Liz Watson of Stone Roofing, to join the crew and support our RANZ team members at the tail end of their project on the Sunday. Much of the hard yards had already been completed by the ladies, and the sense of achievement and satisfaction in the air was a low-key, yet significant moment to behold – I loved being there and the chance to get back up on a roof. It was an honour and privilege to join you all – thank you so much for having me Waikato! Congratulations to Jade and team on a brilliant initiative, trailblazing with a highly successful first step. I look forward to seeing what’s up next.

All hands to the roof New Zealand Women in Roofing Hamilton Branch partner with Habitat for Humanity to re-roof an important and much-loved part of the Te Awamutu community.

BY JADE WALKER

It has been an inspiration of New Zealand Women in Roofing, which was launched in June 2019 at the Roofing Association New Zealand’s 25th Conference in Queenstown, to be actively involve in charity events throughout the country and, on the 25th of January 2020, that goal became a reality.

While most were relaxing on their long weekend, the all-women team from New Zealand Women in Roofing Hamilton Branch partnered with Habitat for Humanity to reroof 210 Palmer St, Te Awamutu, and gifted our time installing a much-needed roof for people in need in the local surrounding community. The team on the tools were all members of the Roofing Association New Zealand (RANZ) – those businesses being, The Roofing Specialists Limited, Cooke Roofing, Project Unite and Stone Roofing.

The block of units we worked on offers affordable housing to elderly residents and people with special needs. Nic Greene, Habitat for Humanity’s Central North Island General manager, said that the Palmer Street units are an icon of Te Awamutu, and form part of their accommodation precinct for elderly people, alongside Freeman Court.

“After years of council ownership, we were recently pleased to take over and look to make

much-needed upgrades,” he went onto explain.

“The roof on this particular block was identified as being in disrepair, and we were very keen to get it sorted before winter. It was fabulous to hear that Jade and the group wanted to come on board, and I have no doubt that they will find it incredibly rewarding working in the company of our elderly tenants.”

Residents at Palmer Street retain security of tenure and an affordable rent level through subsidies provided by Habitat or Government programmes. Built from brick in the 1950s, the one-bedroom and bedsit housing units are in single-level blocks, with a central ‘community room’.

As well as providing rental opportunities, Greene said the housing charity had a strong focus on home repair work in the North Island, where it carries out work at-cost for low income homeowners, asking for no-interest payments up to five years.

“A lot of this work involves re-roofing or roofing repairs, and so we always have our ear to the ground for contractors around the country who’d like to be part of what Habitat does.”

This proved not only a great opportunity to give back to the wider community, but also brought us closer together as a branch, continued on page 19

where it was highlighted that even when you work within an office environment you can still pull your socks up and put on a tool belt.

Three of the branch members at the time of the re-roof are actively involved in their Long Run Roofing and Metal Installation Apprenticeships, where others within the branch are directors of companies, procurement and quantifying and healthand-safety management.

The weekend temperatures hit well over 30 degrees, but the team believed it felt more like 40 degrees up on the roof. Habitat provided all the materials needed to carry out the work, and the branch provided the time and labour. The tenants were most appreciative of the work done and were constantly offering cold drinks – some even brought lemonade ice blocks and chocolate.

We faced challenges such as excessive heat*, power tools jamming, differing finishing techniques and workmanship expectations,

and time away from family and loved ones.

The drive to succeed with this re-roof and running as smoothly as possible meant a lot to us as an Association, and we hope to continue carrying out these charity re-roof projects and also inspire others within our industry to partake.

As I look back and reflect on weekend of the 25th and 26th January 2020, it gives me a great sense of pride knowing that we remained focused on what brought us all together in the first place – the empowerment of women in our industry, supported by our four pillars: Education, Mentorship, Recruitment and Networking.

I want to thank the entire Hamilton branch team for their efforts to make the re-roof a success. Without each and everyone’s help and assistance, we would not have been able to succeed.

Every effort makes a difference!

COMPLIANCE

Don’t ignore the paperwork!

It may be boring or bewildering or both, but producing the correct paperwork is as important as doing a good job up top.

Many of you joined the roofing game to be hands on, outside in the fresh air – certainly not chained to a computer at a desk, inside an office. However, you have woken up in 2020 to discover that you are spending a large proportion of your time dealing with paperwork – yuk!

But let’s not get too distracted by LBP rules.

After all, LBP ROWs (Records of Work) are only a whodunit, they do not record compliance.

That is why you are continuing to be asked to producer statements as well.

Certainly the amount of paperwork has increased hugely over the past two decades.

You may well ask – why is that? Well, it has primarily been about recording and justifying compliance, so that if you get it wrong you are easily found, and there is a paper trail of what you did on that project and to keep you honest.

Literature from manufacturers is required to justify plans during building consent. There are many roofing manufacturers who do full system warranties, so they produce inspection records, photos, and PS4s. Unlike many other industries roofing has had a long tradition of warranties that outstrip B2 durability for cladding of 15 years. But warranties are hollow unless you have the substance behind them. A PS1, or paper from a supplier saying their product has a 20-year warranty, is about the production not about the installation. And again that is why you are asked to demonstrate or justify what you have done on site.

LBP Records of Work People often blame local councils for this, but it is in fact enshrined in legislation. The Building Act requires LBP roofers to do records of work. However, as of January 2020, restricted building work laws limits LBP work to residential houses and apartments up to 10 metres in height. So the rules around what you need to record is limited by this.

Commercial roofers are fair game to be asked for anything and everything to demonstrate compliance. Or basically the installers have installed a complying roof!

22

Autumn 2020 • Issue 92

Producer statements (PS3s and PS4s)

Habitually, you have written producer statements to give to head contractors, clients and councils. There have been situations where LBP roofers have left their staff unattended onsite to do the whole job and then written a ROW. This ignores the basic rules of supervision and thus the council has

asked for further evidence (sometimes photos) to justify why the roof complies. Contractually, you may be required to produce a lot more paper in order to get paid.

Your major disadvantage these days is the health and safety requirement (whilst protecting life and limb) inhibits a supervisor’s or inspectors’ ability later (gaining access to the roof in order to check the work). If it does not happen whilst scaffolding and edge protection is still in place, it won’t happen.

Drones have their limits!

Simple tips for report writing So some of you take this next level. You ditch the tools and get into writing reports or becoming an expert witness on roofing condition assessments. Getting up on roofs these days is harder than it has been in the past, so the degree to which you can inspect the roof is really important. Some of these reports may end up as evidence in court, so we must take care. This article provides a few simple tips you can implement in your business to ensure a consistent standard and format.

When you express an opinion around the existing condition of a roof, you need to take care. Many of our building colleagues and

pre-purchase inspectors have been caught out giving ‘off the cuff’ verbal OKs. It is also tempting to go to the other extreme. So where is the line? Quite simply, what is the brief? Has the scope of work included a full report with photos, recommendations, or just a ‘status quo’ report? Often you can be led into a naïve and over-simplistic question, ‘is the roof OK?’ Be VERY careful saying the Phrase ‘xxx does not comply’. Where is your benchmark?

What standard did you measure against?

Remember the NZ Building Code is performance based so that doesn’t help.

Even E2/AS1 Weathertightness and B2/AS1 Durability have gaps which manufacturer’s info or installation guides usually fills, OR the trade skill of the roofer.

We use a lot of jargon in our industry. Not everyone else, and certainly not our clients, understand it. You may want to add in a standard phrases section e.g. E2/AS1 External Moisture.

• Scope

Also remember that with commercial roofing you do not have to be an LBP. So be careful when you say, ‘a non-qualified person xxx’.

They don’t have to be qualified by law.

Think about what type of reports do you write, who is the report for, and what is the brief?

EMPLOYMENT LAW

Bonding staff for training Investing in your staff is always a good thing, but what are the legal aspects of bonding staff members to a business?

Business owners often look to fund training and development of their staff for the benefit of both parties. Is it legal to ‘bond’ your employees, and what timeframes are acceptable? Unfortunately the answer isn’t always as straightforward as we might like it to be. Businesses can of course include clauses in their Employment Agreement binding an employee to them for a period of time following training, or as we suggest, a specific Bonding Agreement, but the test is really whether that agreement will be enforceable if tested by the courts – and it’s usually a case-by-case decision.

A Bonding Agreement generally binds an employee to the business for a certain period of time, at which point the parties agree the debt is paid and the business has had sufficient benefit from the employee’s extended education. If the bond gets broken – ie, an employee leaves prior to the agreed bonding period – the staff member must reimburse the employer a pre-determined proportion of the cost.

Where an employee is simply being trained for their current job or role, this is often viewed as a major benefit to the business and not necessarily the employee. In this instance it is often deemed unfair and thus unlawful to

bond staff for this type of training. However, if an employee gains a formal qualification or equivalent industry recognised skill through such training, which is clearly of personal benefit, then the business has a valid and enforceable case to bond the employee in order to gain value from the expense and investment they have incurred.

As with any agreement, both parties must agree on the terms and conditions in the bond. The terms will of course vary depending on the particular course or training in question. For example, the cost of the training, direct and indirect, the length in time to complete the training, any time off required, extra hours outside standard business times required of the employee… the list goes on. These factors must be weighed up against what is a reasonable length of time to bond an employee to the business in return for funding their training.

Common practice is that it is generally accepted that bonding periods should be no longer than two years – however, longer periods can be agreed to by both parties.

This, of course, is in extreme cases. The bond period for training for regular roles is rarely longer than 12 months.

The trouble really begins when bonds get broken and the business seeks enforcement.

If the courts or the Employment Relations Authority (ERA) deem the terms and conditions harsh and oppressive in relation to the training offered, a bonding agreement isn’t worth the paper it’s written on.

In conclusion, bonding staff is common practice within many industries, but as an employer, ensure you use a comprehensive, detailed and separate agreement. Do it at the time you seek to train the employee and critically look at the terms from both sides of the employment relationship. If you intend to tie an employee to your business it has to be reasonable and mutually beneficial.

TECHNICAL

Gutter and downpipe design We often hear about internal gutters flooding. This is not because they are inherently unsafe, it is because, by using the Acceptable Solution, they are designed to fail.

BY ROD NEWBOLD

At the beginning of November last year the updated Code of Practice (COP) section on roof drainage was released. This was the most challenging section we have tackled in the current v3 revisions.

Ratio to 10 min maximum rain rate

Normally we try and parallel the Acceptable Solutions and focus on offering solutions for situations not covered by the Acceptable Solution. The reason for this is that were we to disagree, if someone followed the COP and it disagreed from the Acceptable Solution, we could lead them into a dispute with the Consenting Authority that they may not win. So, where we can live with it, we sometimes concur with an Acceptable Solution, even where we believe it is overly conservative.

Roof drainage is different, however. In this section we are far more conservative than the Acceptable Solutions. Try as we did, we simply could not justify publishing gutter and downpipe recommendations in compliance with E1/AS1, as we believe them to be dangerously unconservative.

Why we differ from E1/AS1 So why are we different? Our major points of difference are: •

verage return interval. The Building Code says that buildings A must have less than a 2% probability of flooding. That requires using rainfall intensity with a return period of 50 years. Yet the charts in E1/AS1 are for a 10-year return period.

The COP uses the 50-year ARI figures; depending on location that is a difference of close to 40%.

The COP calculator uses 10-minute intensities, because that is what is readily available, and applies a short-term intensity multiplier to convert them to a shorter-term intensity. For instance, for Residential Internal it defaults to 3.1, designers can opt to increase this if the risk of a 50-year flood cannot be tolerated, but it cannot be reduced.

Industrial Internal defaults to 2.2, as on most commercial sized jobs the travel time of rainfall will be closer to 2 minutes. External gutters have various factors depending on the assessed consequence of occasional overflowing.

hort term rainfall intensity. E1/AS1 uses the maximum intensity S over a 10-minute period. That may be fine for ground drains where flash downpours take longer to reach the drainage channel, but is inadequate for roofs, where flooding can occur in less than 1 minute.

Autumn 2020 • Issue 92

The above graph shows the difference between 1-minute and 2-minute intensities, compared with the 10-minute intensity used in E1/AS1. The horizontal line shows the median, the box represents the upper and lower quartiles, and the dotted line the complete range. It shows that a 1-minute intensity can be as much as 4.3 times the intensity over a ten-minute period.

All the above variables are interactive, you can make the changes on-line and see what effect they have on allowable catchment areas.

The above two inconsistencies alone account for much of our divergence, but there are others. So this time we followed our own path, and with the help of expert advice from Opus, have published our own solutions. These are consistent with the Standard AS/NZS 3500 but employ worksheets to simplify the calculations contained in that complex document.

If all you want is a design that merely complies with the requirements for a consent, use E1/AS1, but if you desire a design that won’t flood, consult the COP.

The COP offers more options The COP recommendations also offer more options in design criteria than E1/AS1.

•

Gutter fall. The COP calculates capacity of internal gutters with different degrees of fall. This has a big effect on capacity. E1/AS1 has no minimum fall for internal gutters, E2/AS1 pokes it’s nose in and says minimum fall must be 1:100 (10mm per metre), which is often unachievable. The COP has a minimum fall of 1:500, but allows designers to calculate the extra capacity they can achieve by increasing the fall. The COP recommends a 1:200 fall (5mm in 1 mm), as it will improve drainage and self-cleaning.

Freeboard. Again E1/AS1 and E2/AS1 disagree. E1/AS1 has no requirement for freeboard on gutters. The COP has minimum freeboard for internal gutters and valleys

•

External gutters. It gives options for external gutters with and without overflow.

•

Internal gutters. It calculates the effect of the wetted area on water flow. The less wetted area, the freer the flow. The optimal ratio is that the width should be two-times the height.

•

Valleys. It gives maximum catchment for common valleys at pitches other than the minimum pitches given in E1/AS1. The capacity of custom-sized valleys can also be calculated.

•

Downpipes. The downpipe capacities are variable according to the rainfall intensity of a location, and options are given for downpipes with and without overflow.

The maximum catchment for the design is then given. If the design catchment exceeds this, gutter design, slope, or catchment area can be altered to find a working combination. Similar inputs in downpipe and (if required) valley calculations can be entered, for which the rainfall intensity input on the gutter sheet is retained.

When we invented Tyvek, we invented building wrap.

Before 1980 building wrap didn’t exist as we know it. Not until DuPont™ created a synthetic product you could cut but not tear, and which allowed moisture vapour to pass through but nothing else. DuPont™ Tyvek® was born and since then it has been the weather tightness system of choice for builders across America, Asia Pacific and Europe.

Now we’re partnering with Pink® Batts® to distribute Tyvek® in New Zealand, which means DuPont™Tyvek® is available wherever you buy Pink® Batts®. As a result you’ll receive the same proven service from our dedicated technical support team too.

So, for a building wrap that offers quality and reliability that Kiwis expect, trust the international category leader – DuPont™ Tyvek®.

Eye in the sky How drone technology is benefiting the roofing industry and its clients.

EVO in the air

The Health and Safety at Work Act 2015 (HSWA) has made all of us even more aware of our safety and wellbeing obligations to our teams, our customers and ourselves. With this in mind – and in the wake of knee replacement surgery – I was looking for ways in which I could reduce my risk, improve my work practices, and (ideally) improve my service to residential and commercial clients.

Therefore, about 20 months ago, I trialled iRoofing, a roof measuring app which uses images from Google maps. It certainly had the potential to reduce the need to use ladders and work at heights, but some of the imagery was too blurry to take accurate readings. It was the app supplier who suggested I investigate drone photography.

At about the same time, I had started to receive enquiries for roof inspections for insurance purposes. The company specifically requested that these inspections were conducted by a drone, rather than actual access to the roof.

The first drone was a Splash Drone – and the benefits to myself and my clients were immediate. Spotting obvious faults and checking the roof condition became easier and more time efficient. Customers could have ‘before and after’ photos without putting themselves (or anyone else) at risk.

Roofs that had previously been inaccessible due to their height and/or pitch were no longer out of bounds.

Drone technology was surging ahead, and in June 2019 I upgraded from my first drone to an Autel Robotics EVO. The picture quality and controls have improved in just these few months. In fact, clients can now watch their inspection as a high-resolution video. It brings the facts to life; they can see everything in situ, which helps them understand recommendations.

In addition, I had not anticipated just how fascinated clients would be with drone technology. Occasionally, I still hear concerns, but mostly I get asked, ‘please can I watch?’

There are protocols that have to be observed with every flight. Firstly, its has to be logged with AirShare – an app and website codeveloped by the CAA (Civil Aviation Authority), Callaghan Innovation and UAVNZ

(the “unmanned” division of Aviation New Zealand). Also, one of the CAA’s standard checklists for flying within the Class 1 classification has to be completed for each flight. When appropriate, being mindful of the privacy of others, I advise neighbouring properties of my inspections, too.

Drone technology has the potential to offer numerous benefits to construction overall, and roofing in particular. The next generation of drones will likely include thermal imaging, making it easier to identify, for example, heat loss through weaknesses in insulation.

There are some circumstances when only a ladder will do, such as if the weather is inclement, or there are other site constraints.

However, if a business is offering site monitoring, surveying, or measuring (when used in association with an app), I would suggest they investigate this exciting and very practical option.

HEALTH & SAFETY

Fire down below … a hot topic If the recent roof fire at Sky City has taught us all one lesson, it’s that fire risk is omnipresent on all building sites, big or small. Know your immediate environment, assess the risk, and most importantly, be vigilant.

New Zealand buildings, particularly older ones, are extremely flammable. From your classic kiwi bungalow to your mid-twentieth century factory / warehouse, they are packed with extremely dry timber, plenty of dust, bird’s nests and other detritus.

Fire risk is not, however, limited to old, existing buildings. The Sky City Convention Centre and Grenfell Tower incidents have shown us that modern construction materials are perfectly capable of burning rather well, too – and with the added bonus of nasty, contaminant-laden smoke. Such events also remind us that a building fire can be an extremely expensive proposition.

Unlike most worksite hazards, fire does not remain an isolated incident for very long. A small problem can become a major problem in minutes. We also know that the nucleus of a fire can smoulder, undetected for hours (or longer) before taking hold. And in many cases it’s the combination of factors that’s the problem. Oil-based stain, wrapped in rags will ignite many hours after the knock-off time, and a welding slag dropped into sawdust will potentially cause a fire, as will a torch igniting the dust in a roof space.

Roofers packing heat is not an uncommon sight. Not everyone is a flame-wielding, torch-on roofer, but there are plenty of us that use a gas flame or a heat gun to dry a damp substrate. There are also an increasing number of heat-welded roofing products on the market. And, of course, the angle grinder comes out of the tool kit from time to time.

Obviously, no roofer wants to have to front the fire investigators or insurers over what will probably be labelled negligence. Therefore, it is worth considering two key factors:

Always turn the bottle off, not just the hand piece. Do you need a 9kg bottle? A smaller one is easier to handle, less prone to damage and also less destructive in a crisis.

1. What do you use that generates enough heat to ignite something in your workspace?

Always have a fire extinguisher on hand, yes, on hand, not in the van! If you react quickly, it can save your bacon. Don’t however be fooled into thinking that that’s enough. The extinguisher is of little use to you if something is smouldering out of sight, or the flame is racing across the underlay. Prevention is considerably better than the cure.

2. What is in your workspace that can burn?

The common heat sources are pretty obvious: anything that uses a flame, generates hot air, or creates spark or hot waste, such as gas burners, hot-air guns, hot-air welders, angle grinders.

The more interesting question, though, is ‘what can burn?’ The short answer is pretty much everything. The more relevant question is, ‘what can burn that you can’t see?’

Has that grinder-dross landed in an old bird’s nest under the iron? Has the flame touched dust and spiders webs covering the sarking?

Is the hot-air gun superheating the bituminous underlay? Is there flammable building paper up under the cladding edge?

The point here is that it is extremely important to determine what is going on below, behind, above and near where you are applying heat, because, in most cases there will be a significant risk lurking just out of sight.

Flammable gases are a concern. Many are heavier than air, particularly on cold days – days when you are more likely to need some heat! The solvent fumes released from adhesives, etc can hang in the gutter for some time after the adhesive appears ‘dry’.

The air intake on a gun is really good at sucking up these fumes and turning the whole unit into a flame-thrower! Believe me, I have seen it happen.

So, my advice is simple: You really must switch into Sherlock Holmes mode and look very hard for the ‘improbable’ and ‘impossible’ before turning up the heat.

The other factor to consider is the risks you bring to site: Flammable products, plus a heat source.

If you are using gas, are you certain the lines and valves are sound, secure and undamaged?

INDUSTRY TRAINING

Making a positive start Tried and tested advice for young roofers about your first few months on a new job, and what your new boss is looking for.

So, you’ve started a new job and want to impress the boss. There’s a lot of truth in the saying ‘first impressions count’, so what can you do to make sure you make a good one? We’ve got some tips to get you started out on the right foot.

Be on time It’s easy to slip into the habit of sneaking into work a little late, but that kind of thing is noticeable – especially when you’re the newbie.

It might not seem important, but being punctual is a big deal for a number of reasons: • It shows respect to boss and your work mates •

It shows that you take your work seriously

• It shows that you’re organised and good with time management All of these points are important when your boss is thinking about whom to promote later down the track.

Get to know your team Outside of your skills to actually do the job, your boss will also be looking to see if you’re a good fit for the team. To prove that you are, spend a bit of time getting to know your new team and help out with the little things – for example, get involved if someone needs a hand moving something on site, or needs a second opinion.

Having great relationships with your work mates also make the days go by faster, but there are also other benefits for both you and your employer including:

On the flip side, poor relationships and a bad workplace fit can make going to work a living nightmare; it also lowers productivity and can reduce efficiency. Showing that you are a good match for your team is a great look for you and a relief for your supervisor; especially if they can see that productivity has increased within the team since you arrived.

Learn, learn, learn If you’re doing an apprenticeship, you’ll be learning new things every day. Showing a good attitude to learning on the job can go a long way when it comes to impressing your supervisor.

If you’re unsure of something ask questions, write things down, and don’t be afraid to ask for a second opinion from someone more experienced in the team.

Struggling with your off-job learning, because you might be dyslexic?

Just let your boss know and they can alert the team at Skills, who can get you learning support to help you ace the books.

If everything you’re taught goes in one ear and out the other it’s not a good look. There will also be times when your supervisor wants you to learn things that aren’t in your job description – for example, pricing up jobs for clients. Jumping on the opportunity to learn these new skills will impress the boss, because it shows that you’re flexible and someone they should keep in mind for future promotions.

Your attitude in the first few months will set the tone for the rest of your employment and help gear you up for success in the future.

• Jobs get done faster because teammates help each other out when needed •

Work becomes more enjoyable

• Happy, efficient teams mean better quality of work

Michael ‘Bucko’ Sentch Manager, Project Unite Q Where are you based?

A Hamilton.

Q Years in roofing?

A Almost hurts to admit it, but 23.

Q How did you get started in roofing?

A As a slightly wayward teenager, my dear old dad decided it was in my best interests to spend any and all of my spare time working on site, as a labourer – apparently it teaches discipline.

Q Family nucleus?

A I work with a number of my closest family, including my parents. I’m married with two wonderful, and at times challenging, children – daughter Esther 7, son Michael (Vincenzo) 3.

Q What motivates you?

A Aside from my family and my fantastic team, I am fortunate to be part of innovation in business and construction.

Q What do you do day to day?

A What we all do… fight fires and try and go to bed at night with less problems on my plate than I started the day with.

Q Favourite products/brand? Why? A Rolls Royce. Not particularly fond of the actual automobile, but more what the

NEW – HOW-TO PROFILE METAL WALL CLADDING brand represents. It is something we discuss regularly as a team and strive to create/emulate.

Coming soon – June 2020 release.

Q Favourite roof?

A Any completed by Project Unite over the past 36 years (shameless plug) or for sheer scale, complexity and aesthetic the Abu Dhabi Midfield Terminal – at one stage they had 900 roofers on site, and were looking to double the size of the crew.

Q Favourite beach?

A Coolangatta (Aus), Huntington or Manhattan (both in LA).

Q Favourite movie?

A Snatch.

Q Favourite brew o’ beer or wine?

A Spanish Rioja.

Q What’s on my playlist?

A Don’t listen to a lot of music, but would unashamedly admit there would be a lot of Tupac, Biggie and Six60.

Q What makes a top roofer?

A Attitude, commitment and selfmotivation. If anyone possesses those qualities they can ‘make’ themselves in to literally anything.

Q Where will roofing be in 20 years?

A Hopefully in my past.
