We work on commercial, light industrial and multi-unit residential roofs in South Auckland, from a single box gutter repair to a full re-roof staged over an occupied building. Only one section is open at a time, with weather contingency and protection for stock and equipment below, and some tasks can be scheduled outside business hours.
South Auckland commercial and industrial roofs: Wiri, Manukau and beyond
South Auckland has some of the largest concentrations of industrial and commercial roofing in the city. Around the Manukau city centre and the Wiri industrial area, buildings from the 1970s onward carry long, low-pitch runs, box gutters and plenty of plant penetrations. Many of those roofs are now old enough for corroded laps, failing seals and brittle translucent sheets, and re-roofs have to be staged so trading continues underneath.
The flat, open land through Manukau, Papakura and Takanini leaves big roofs exposed to wind from the Manukau Harbour and the farmland to the south, so fixing patterns along long sheet runs and ridge flashings need to suit the wind zone. Low pitches are prone to ponding and blocked outlets, and older box gutters may not have been sized for extensions added later. We check capacity and overflows as part of every inspection.
Further south, the commercial roofs change character. Around Pukekohe the work includes large sheds and rural commercial buildings serving the market gardens, where long spans and condensation inside unlined steel buildings are common concerns. In Takanini, soft peat ground with a record of settlement can affect wall junctions and flashings on some buildings. Across the south, pre-2000 buildings with fibre cement roofing must be tested before work begins, and we coordinate site inductions and permits with each facilities team. Regular condition reports also let owners plan a re-roof as a budgeted project rather than an emergency after a storm.
Local tip: If your South Auckland warehouse drips inside on cold, dry mornings, ask for the roof to be checked for condensation as well as leaks.
Commercial Roofing in South Auckland: Local Conditions
South Auckland's flat, open sites expose large roofs to wind across the Manukau Harbour, so fixings and ridge flashings take the brunt. Older outbuildings and pre-2000 buildings may carry fibre cement sheeting, which is tested for asbestos before any work is planned.
Roofs in South Auckland
Post-war state houses and family homes in Manurewa, Papatoetoe and Māngere were built with a mix of corrugated iron and tile roofs, and 1960s and 1970s houses often carry concrete tiles or decramastic. New homes in Takanini, Papakura and the surrounding developments are mostly longrun steel or concrete tile, with a growing number of low-pitch longrun roofs on townhouses. Rural properties around Pukekohe have longrun on houses and sheds, sometimes alongside older corrugated outbuildings that may contain fibre cement sheeting.

Commercial Roofing South Auckland FAQs
Why does our Wiri warehouse drip inside when it has not rained?
That is usually condensation forming on the underside of an unlined steel roof as it cools overnight. The fix depends on the building, and can involve underlay, insulation and ventilation working together. We inspect and recommend the right approach.
Why does our warehouse drip inside when it is not raining?
Usually condensation forming under the roofing or on purlins in cold conditions. BRANZ has researched this in large steel-framed roofs. The fix is in insulation, underlay and ventilation design, not sealant.
Do you work on body corporate and apartment roofs?
Yes. Multi-unit residential roofs often need consent and Licensed Building Practitioner involvement for larger work, which we handle as part of the project.
