Stripping a tired roof back to the purlins is one of the bigger jobs a Dunedin house will ever need, and the best roof replacement in Dunedin starts with a roofer who understands how the city’s wind, driving rain and salt air work on a building. The contractors below re-roof homes and commercial buildings across the city in longrun steel, metal tile, membrane and asphalt shingle, and most handle the spouting, flashings and scaffolding that come with the job. Roof replacement in Dunedin now leans heavily on longrun and metal tile profiles, and firms such as Dunedin Roofing Systems and Horizon Roofing work across both.

How to Choose the Right Roof Replacement in Dunedin
- Check the roofer is a Licensed Building Practitioner, since re-roofing a house is usually restricted building work.
- Ask which material the quote is based on. Longrun steel, metal tile, asphalt shingle and membrane all behave differently on an exposed or coastal Dunedin site, and the price gap between them is real.
- Get the workmanship warranty and the product warranty in writing, and check how long each one runs for. They are two separate things.
- Confirm who supplies and pays for the scaffolding or edge protection. A roofer with its own scaffolding crew will price it differently from one who subcontracts it.
- Ask what happens to the old roofing material, how the site is made weathertight each evening, and who deals with the skip.
Frequently Asked Questions About Dunedin Roof Replacement
What does a roof replacement in Dunedin cost?
There is no single figure, because the price follows the roof rather than the house. Pitch, height, the number of valleys and penetrations, whether scaffolding is needed, the material chosen and whether the old roof contains asbestos all move the number, so most Dunedin roofers quote after a site visit rather than over the phone. Ask two or three companies to price the same material and the same scope, otherwise you are comparing different jobs.
How do I check a roofer is licensed?
Re-roofing a home is generally restricted building work, which means it must be carried out or supervised by a Licensed Building Practitioner. You can search a person’s name or licence number on the public register at lbp.govt.nz and see which licence classes they hold and whether any complaints have been upheld. Ask for the name of the individual practitioner, not just the company name.
Do I need a building consent to replace a roof?
A like for like replacement of an existing roof often falls under exempt building work, but changing the roof material, the structure underneath or the load the framing carries can change that. Swapping heavy concrete tiles for lightweight steel, for example, is worth checking first. The exemptions are set out at building.govt.nz, and the Dunedin City Council building team can confirm whether your particular job needs a consent.
Which roofing material suits Dunedin’s climate?
Longrun steel in a coated finish such as ColourSteel is the common choice, because it is light, sheds rain quickly and comes in grades made for salt laden air. Pressed metal tiles give the look of a tiled roof at a fraction of the weight, which matters on older houses. Membrane systems are used on flat and low slope roofs, decks and garage tops, and asphalt shingles suit some architectural roof shapes. A roofer will match the profile and the coating grade to how exposed your site is.
Can a tile roof be replaced with metal?
Yes, and it is a common job in Dunedin’s older suburbs. Removing concrete or clay tiles and fitting lightweight coated steel takes a lot of load off the roof framing and usually improves how the roof handles wind. The roofer will check the existing purlins and battens first, because spacings suited to tiles are not always right for longrun sheet, and some framing work may be needed as part of the conversion.
How long does a re-roof take, and do I need to move out?
A straightforward house re-roof is usually measured in days rather than weeks, with scaffolding going up first and the roof made weathertight at the end of each day. You do not normally need to move out. It is noisy while the crew is on the roof, the site carries the usual hazards of vehicles, tools and scaffolding, so children and pets need to be kept well clear, and it pays to move a satellite dish before work starts rather than after.
Which parts of Dunedin and Otago do these roofers cover?
Between them the companies on this page work across the city and well beyond it. Caversham and South Dunedin are where two of them are based, and the stated service areas take in Mosgiel, the Otago Peninsula, Waitati and Warrington to the north, and Balclutha and the Clutha district to the south. Several also travel to Waitaki, North Otago and Central Otago. If the property sits outside the city, say so when you first make contact, because travel affects both scheduling and price.
What warranties should come with a new roof?
Expect two. The material carries a manufacturer’s product warranty, which varies by profile, coating and how close the building sits to the sea, and the roofer provides a separate workmanship warranty covering the installation. Warranty periods differ between companies, so ask for the length of each in writing before you accept a quote, and keep the material warranty certificate with your house papers.
How We Chose the Best Roof Replacement in Dunedin
Every business in this guide was found by searching for roof replacement in Dunedin, then checked against its own website. Names, addresses and phone numbers are taken from the business’s own site rather than a directory feed, so what you see here is what they publish themselves. We also check that each one is actually based in or genuinely serving Dunedin, rather than a national operator running a local landing page. A business with no website of its own is not listed, because there is no primary source to verify it against.
