SWP Commercial's Christchurch branch sits in Wigram and is part of a company that has spent more than 30 years roofing some of New Zealand's most high-profile buildings. Describing itself as New Zealand's leaders in commercial roofing and specialist coatings, SWP delivers innovative roofing and waterproofing solutions for commercial buildings nationwide, pairing quality workmanship with a strong emphasis on health and safety on every project.
The company was founded through the merger of SurfaceWorks, a painting and exterior coatings specialist, and Waterproofing Plus, experts in roofing and waterproofing. That combined expertise set SWP's focus on the commercial sector and fuelled a decade of growth from Wellington into Auckland, Christchurch and, most recently, Tauranga. In 2019 the business launched SWP Maintain, a dedicated arm for active, preventative roof care, reflecting a belief that commercial roofs deserve better long-term attention.
From the Christchurch base, the team offers three core capabilities: commercial roofing with expertise in metal and membrane warm roof systems; roof overlays, which re-roof existing buildings without disruption while improving performance and lifespan; and car park coatings and specialist resin flooring, using heavy-duty liquid membranes to protect large car park decks and high-performing resin floors for demanding commercial environments. SWP works collaboratively alongside New Zealand's leading construction firms, including LT McGuinness, Naylor Love, Hawkins and Southbase, and its project list ranges from the Lyttelton Port Company Workshop and a roof overlay at Woolworths Northlands Mall through to the Takina Wellington Convention Centre, Park Hyatt Auckland and Nelson Airport's architecturally striking terminal.
Health, safety and trust underpin the operation, with memberships including Site Safe, the NZ Roofing Association, the Waterproofing Membrane Association and the National Roofing Association of America. Through SWP Maintain, clients can also book transparent roof inspections, complete with photos, videos and condition grading, or sign up to RoofCare+, a custom maintenance plan covering inspections, cleaning, prompt repairs and warranty upkeep. The Christchurch team can be reached on 03 344 6458 or at info@swpcommercial.co.nz.
Tucked into the Wigram industrial area at 1/13 Parkhouse Road, SWP Commercial's Christchurch branch is the local arm of a company that calls itself New Zealand's leaders in commercial roofing and specialist coatings. From this South Island base, the team delivers roofing, waterproofing and resin flooring solutions for some of the region's most demanding commercial buildings — with no shortcuts, as the company's own motto puts it.
SWP Commercial focuses on three core capabilities. First, commercial roofing: the team are experts in metal and membrane warm roof systems. Second, roof overlays — a reroofing method that installs overlay systems onto existing roofs, improving building performance and lifespan without the disruption of a full strip and replace. Third, car park coatings and specialist resin flooring: heavy-duty liquid membranes that protect large car park decks, and high-performing resin flooring for demanding commercial environments.
Alongside the new-build and reroofing work sits SWP Maintain, the company's dedicated maintenance arm launched in 2019 and described as New Zealand's leading roof maintenance provider. It starts with roof inspections — transparent, detailed reports featuring photos, videos and expert condition grading, flagging urgent health and safety concerns, needed repairs, and the roof's estimated remaining serviceable life. From there, clients can move onto RoofCare+, a custom maintenance plan covering inspections, temporary repairs to urgent problems on the spot, cleaning of gutters, outlets and loose debris, and active maintenance to keep roof warranties upheld.
SWP's story spans more than 30 years. The business was founded through the merger of SurfaceWorks, a painting and exterior coatings company, and Waterproofing Plus, specialists in roofing and waterproofing. That combined expertise steered the company toward the commercial sector and set the stage for national growth: over the following decade SWP expanded from Wellington into Auckland, Christchurch and, most recently, Tauranga.
Christchurch sits firmly on that map. Local projects include the Lyttelton Port Company Workshop, completed in 2023 with Roof Logic's Ultratherm MSR warm roof system; a roof overlay at Woolworths Northlands Mall; the New Brighton Surf Club roof; and architecturally demanding builds like the St Andrews College Chapel. Nationally, the portfolio stretches to Nelson Airport's geometric architectural warm roof, the Takina Wellington Convention Centre (2023) and Auckland's Park Hyatt (2020).
Collaboration is central to how SWP works. The company has built long-standing relationships with many of New Zealand's leading construction firms — Naylor Love, LT McGuinness, Hawkins, Southbase and Downer among them — plus suppliers such as Roof Logic, Seaman Corporation and Roofing Industries. Rather than just delivering a finished product, SWP works alongside clients to guide smart, value-led decisions, an approach it credits for its long-standing industry trust.
Health and safety carries a strong emphasis on every project. SWP holds Site Safe membership and SiteWise green sticker status, is Impac Prequal certified, and belongs to both the NZ Roofing Association and the Waterproofing Membrane Association — plus, notably, the National Roofing Association of America.
SWP describes itself as built on opportunity: a workplace where people feel safe, valued and proud. Everyone in the business, the company says, started on the tools, and the culture rewards hard work with career progression. The vision is to be New Zealand's most trusted name in commercial roofing and coatings, setting the standard for protection, performance and innovation so every building worked on stands strong for decades to come.
