A full re-roof in Manukau replaces the old roofing, underlay, fixings and flashings with a new COLORSTEEL roof built to today's Building Code. It is the point where you stop paying for repairs every winter and get a roof with a manufacturer's material warranty and our workmanship behind it.
Manukau re-roofs: 1970s homes nearby, long industrial runs in Wiri
Manukau was laid out from farmland bought in 1966, and the homes and state houses built around the new centre in the late 1960s and 1970s are now reaching re-roof age together. Many carry concrete tiles that have outlived their own ridge bedding, fixings and underlay, or decramastic that is shedding its stone chip. Some older decramastic contains asbestos, so it is tested before removal, and changing to COLORSTEEL takes a fair amount of weight off the frame.
The other half of the work sits in the commercial and industrial land. Wiri and the retail strip around Westfield Manukau City and the Manukau Supa Centa have large, low-pitch longrun roofs where a re-roof has to be staged so only a section is open at once. Box gutters on these buildings are checked for capacity and given overflows that can take the full flow, because an outlet that blocks during heavy rain sends water inside the building line.
Both types of roof share the same weather. Manukau sits on flat, open ground between Papatoetoe and Manurewa, with wind coming across the harbour and the farmland to the south, so ridge flashings and fixing patterns are specified for that exposure. On rental homes we also plan access and noisy strip-off days with tenants in mind. Where a house and a nearby commercial building share an owner, the two roofs can be measured on the same visit, though each gets its own scope because the details and staging are so different.
Local tip: If your 1970s Manukau home has a tile roof, check the ceiling space for stains near the ridge, since ridge bedding and underlay often fail before the tiles do.
Re-Roofing in Manukau: Local Conditions
South Auckland re-roofs are often on post-war family homes and state houses in Manurewa and Papatoetoe, plus rural houses and sheds around Pukekohe. Older outbuildings and fibre cement roofs are tested for asbestos before any removal starts.
Large-span commercial and industrial re-roofs are staged section by section so the building stays weathertight.
Homes in Manukau
Manukau's homes and state houses from the late 1960s and 1970s often carry concrete tiles or decramastic, alongside older corrugated iron. Concrete tile roofs fail at ridge bedding, fixings and underlay, while decramastic sheds its chip and rusts, and some older decramastic contains asbestos. The commercial centre and Wiri bring large low-pitch longrun roofs, box gutters and plant penetrations. Many older box gutters were never sized for the roof area they now serve, and BRANZ recommends overflows that can take the full flow if an outlet blocks.

How We Handle Re-Roofing in Manukau
New flashings are folded to suit your roof, rather than forced into standard shapes, and fixed to the NZ Metal Roof and Wall Cladding Code of Practice. That is where most leaks on poorly installed roofs begin, so we take the time to get it right.
Pricing: every roof gets a free on-site measure and an itemised written quote, with a fixed price agreed before any work starts.

Re-Roofing Manukau FAQs
Is a 1970s Manukau house with concrete tiles worth re-roofing in steel?
Often it is. By this age the ridge bedding, fixings and underlay under concrete tiles tend to be failing even if the tiles look sound, and moving to COLORSTEEL removes a heavy load from the frame. An inspection confirms whether repairs would still give you useful years.
Can we stay in the house during the re-roof?
Yes, most people do. There is noise during the day and some dust in the roof space, and we will ask you to move cars and anything fragile on interior walls. We keep the house weathertight every night.
Can I change from tiles to metal?
Yes. Tile to metal is one of the most common re-roofs in Manukau. Steel is much lighter than concrete tiles, but the purlin spacing and fixings need to suit the new roof, and a change of material can affect whether a consent is needed. We check both before quoting.
