Re-Roofing Cost Auckland

The ranges below are other people's published figures, not our prices. Our quotes are itemised after a free on-site measure, so you can see what each part of the job costs and compare quotes line by line. For a firm figure, book a free measure.

Published price ranges per square metre

Re-roofing is priced per square metre of roof area, not floor area. A pitched roof with eaves has more area than the floor plan beneath it, so a 150 m2 house can easily have a larger roof than that.

These are the most recent Auckland figures we could find from published third-party sources. They are indicative only, they move with material and labour costs, and each source defines what is included slightly differently.

• Made 4 Tradies, roofer rates guide (checked September 2026): Auckland re-roofing $95 to $150 per m2; long-run steel re-roofing $80 to $135 per m2 nationally; decramastic tile replacement $95 to $150 per m2; a full residential re-roof of 130 to 180 m2 at $15,000 to $35,000 or more.

Roof size, shape and pitch

Area is the starting point, but shape matters almost as much. Every hip, valley, dormer, skylight and chimney adds cutting, flashing and labour time. A simple gable roof goes on far faster than a hip roof of the same area with several valleys.

Pitch affects both safety and speed. Steeper roofs need more edge protection and roof anchors, and roofers move more slowly on them. One published guide estimates that steeper pitches add around 15% to 25% to labour. Very low pitches bring their own limits: the NZ Metal Roof and Wall Cladding Code of Practice sets a minimum pitch for each profile, for example 8 degrees for standard corrugate, so some low-pitch roofs need a trapezoidal profile or a membrane instead.

Access, scaffolding and edge protection

Most re-roofs need scaffolding or edge protection to meet health and safety requirements. The cost depends on the height of the house, the length of the perimeter, the slope of the section and how close neighbours are. One published guide puts edge protection or scaffolding at $1,500 to $3,500 or more per project.

Two-storey homes, steep sections, narrow side access and properties without room for a skip or a delivery truck all add cost. These are assessed on site, which is why a quote from a photo or an aerial measure is only a starting point.

Removing the old roof, including asbestos

Stripping and disposing of the old roof is a real line item. Concrete tiles are heavy and slow to remove, and roofs with several layers or old sarking take longer. Rotten purlins, battens and fascia found once the roof is open are extra, which is why a good quote states how timber repairs will be priced.

WorkSafe advises that homes built before 2000 may contain asbestos, and lists roofing such as Super Six corrugated fibre cement and decramastic tiles among the common examples. Testing confirms it. Removing more than 10 square metres of non-friable asbestos needs a WorkSafe licensed removalist, and any friable asbestos needs a Class A licence. This is one of the biggest variables in re-roofing cost, so test early.

Material, profile, underlay and flashings

Pre-painted steel is the most common re-roofing material in Auckland. COLORSTEEL MAXAM is designed for most New Zealand environments including many coastal sites, while ALTIMATE is a premium product for extreme marine and highly corrosive sites, and costs more. Corrugate and trapezoidal profiles are priced similarly; standing seam and tray profiles cost more.

Underlay goes under the roofing and is required to last as long as the roof cladding. Flashings at ridges, barges, valleys, aprons and penetrations are folded to suit each roof, and complex roofs need more of them. These details do not show from the street, but they are where cheap roofs leak, so check they are itemised on every quote you compare.

• Roofing underlay and any safety mesh
• Ridge, barge, apron, valley and penetration flashings
• Fixings to suit the exposure zone
• Spouting, downpipes and fascia, if included

Spouting, consent and the extras that change the total

Replacing spouting and downpipes at the same time as the roof is usually cheaper than doing it later, because the scaffolding is already up. Fascia repairs, skylight replacements, chimney removal and extra ventilation all add to the total if included.

Replacing a roof with a comparable product in the same position is generally exempt from building consent under Schedule 1 of the Building Act, but changing material, altering structure or replacing a roof that failed early can need consent, which adds fees and time. In Special Character Areas, a change of roof material or profile may also need resource consent. Ask every roofer to state what they have assumed about consent in writing.
