Residential Roofing in Auckland
If your roof is starting to leak, showing signs of corrosion, needing repeated repairs, or simply reaching the end of its serviceable life, you may be wondering whether it can still be repaired, or whether it's time to replace it.
Impact Roofing Solutions provides residential roofing across Auckland, from roof replacements and new roofs to repairs and maintenance. We use recognised roofing systems and brands. Some of these include COLORSTEEL® and COLORCOTE®, selected to suit your home, roof design and corrosion exposure, with installation carried out by a Licensed Building Practitioner and in accordance with the NZ Metal Roofing Manufacturers Code of Practice and Building Code performance requirements.
Not sure whether you need a repair or a new roof?
Enquire NowAs a guide, most residential roof replacements in Auckland land somewhere between $15,000 and $45,000 for the roofing itself. Where your project sits within that range depends on the roof, the existing structure, access, materials and the amount of detailing required.
That figure covers the roofing work. Many projects also include work beyond the roof itself, such as spouting and downpipes, fascia or weatherboard repairs, skylights, or painting while scaffolding is already in place. Fascia boards often need repairing behind the spouting, and weatherboards sometimes need replacing so new flashings can be installed behind them where the roof meets a wall. Combining this work with a reroof can be an efficient way to tackle several exterior jobs at once, but it can also increase the overall project cost.
Older roofs can bring additional considerations too. Some older roofing products, including certain decramastic tiles, may contain asbestos. Where asbestos is suspected or confirmed, additional specialist handling and disposal requirements can add to the cost of the project.
Cost follows the actual roof area, not the floor area of the house. A 150m² home doesn't have a 150m² roof. A steeper pitch adds area again, and takes longer to work on safely.
Hips, valleys, dormers, skylights, chimneys and roof-to-wall junctions all need flashings and hand detailing. Two roofs of the same area can cost very different amounts to install.
Purlins, battens and decking can only be fully assessed once the old roof is off. Anything deteriorated is repaired first, and existing purlins are sometimes spaced too far apart for the new roof, so additional purlins are installed to suit its spanning capability.
Two-storey homes, tight sites and sloping sections change how the work is done. Scaffolding and edge protection are priced on the building and the site, not on the roof area.
The profile, coating and fixings are specified for your property and its exposure. Flashings, penetrations, valleys and junctions are part of that specification, not an afterthought.
A common conversion, and it costs more than a metal-to-metal reroof. Tiles are heavy to strip and expensive to dispose of, and the roof usually needs extra purlins added to suit long-run metal.
Scaffold and edge protection go up to suit the job and WorkSafe requirements, and we agree a waste area with you before anything starts. We photograph the property first, then materials are delivered to site.
The existing roofing comes off, along with battens, fixings and building paper where required, and goes straight off site. The roof is made weather-tight at the end of each day. We don't leave a section open overnight.
Purlins, rafters and fascia can only be properly inspected once the old roof is off. Anything rotten or not up to standard is photographed and reported, and we talk to you about it before going further. Roof space ventilation is assessed at the same time: a roof needs airflow to manage moisture, and older homes often don't have enough, or lost it when insulation went in.
Underlay goes on where it's specified, and new treated purlins at the centres the roofing system requires. Ridge, hip, barge, apron and valley flashings are made to suit the profile and colour, and pipes, vents and flues are flashed properly. The detail depends on the system and the building, not a standard kit.

COLORSTEEL® or COLORCOTE®, in the profile chosen for your roof, installed to the manufacturer's requirements with the right fixings, and to the NZ Metal Roofing Manufacturers Code of Practice. The sheets are the part you see; the flashings and penetrations are what keep the water out.
New spouting and downpipes go on where they're in the scope, and drainage and penetrations are checked. The site is cleaned properly, including swarf and loose fixings, and we walk the finished roof with you, or send photos if you can't be there. You get your warranty pack, completion certificate and maintenance information.
The two coated steel systems we install on most Auckland homes. Both come in a range of coatings and grades, and which one suits your place depends on the building, the roof design and how exposed the property is.
Long-run corrugate and trapezoidal profiles cover most homes. Standing seam is the architectural option, with hidden fixings and a solid deck beneath it, and has its own page. Profile choice comes down to pitch, drainage, roof design, appearance and detailing.
Corrosion exposure, roof design and pitch, the look you're after, how long you want it to last, your budget, and the manufacturer's requirements for the system. Choosing a roof isn't just picking a colour. The system has to suit the building and where it sits.

Frequently Asked Questions
Most Impact Roofing Solutions residential roof replacements take 3–8 days of actual work on the roof. From start to finish, including scaffolding, material delivery and clean-up, the overall process usually takes 1–4 weeks, depending on the size and complexity of the project. The timeframe can be affected by the size and shape of the roof, access, weather, the condition of the existing roof and whether additional work is required once the old roofing is removed. We confirm the expected start date when your project is confirmed, and normally confirm the exact start date with you approximately two weeks before work begins.
Several factors can affect the timeframe of a residential roof replacement in Auckland. These include the size and pitch of the roof, its shape and complexity, access and scaffolding requirements, weather, material availability and the condition of the existing roof. Additional work can also affect the programme. Once an old roof is removed, we may find rotten timber, damaged purlins, unsuitable spacing or other remedial work that could not be fully assessed beforehand. Converting a concrete tile roof to metal roofing can also involve additional preparation and structural work. Where unexpected issues are found, we explain what is required before proceeding with additional work.
In most cases, yes, you can remain living in your home during a residential roof replacement. A roof replacement is carried out progressively, with the existing roof removed in sections and the new roofing installed as the work proceeds. At Impact Roofing Solutions, we do not leave sections of the roof exposed overnight. The aim is to keep the building weather-tight throughout the project. There will be some unavoidable noise and activity while the old roof is removed, scaffolding is erected and the new roof is installed. We recommend planning for access around the property and keeping children, pets and other people clear of designated work areas while the project is underway.
The condition of the underlying structure cannot always be confirmed until the existing roof is removed. Once the roof is stripped, we inspect the accessible purlins, rafters, fascia and other relevant substrate for rot, deterioration or defective construction. If damaged or unsuitable timber is found, we photograph the issue and explain what needs to be done. Remedial work is then priced according to the extent of the damage before additional work proceeds. This is one reason why a roof replacement quote should clearly explain what is included in the roofing work and how unexpected structural repairs are handled.
Yes. Concrete tile roofs can be replaced with COLORSTEEL® or COLORCOTE® metal roofing, and Impact Roofing Solutions carries out concrete tile-to-metal roof conversions where the existing building and proposed roofing system are suitable. The project can involve more than simply removing the tiles and installing metal. Concrete tiles are heavier and can require additional labour and disposal, while the existing purlin spacing, substrate and roof structure may need to be assessed or modified for the new roofing system. The final specification depends on the existing roof construction, the proposed metal roofing profile, roof design, corrosion exposure and manufacturer requirements. New purlins, ventilation or other preparation may be required as part of the conversion.
Weather can affect the timing of a roof replacement, particularly in Auckland. Roofing work needs to be planned around conditions that allow the roof to be safely removed and the new roofing system installed correctly. Impact Roofing Solutions works progressively and does not leave a section of the roof exposed overnight. Where weather affects the programme, the timing of the work may need to change to protect the building and maintain safe working conditions. We confirm an expected start date when you accept the quote, or as set out in your building contract, then give you a more specific date as we get within about two weeks of the job. Because roofing depends on the weather, a delay on one job has a knock-on effect on the jobs that follow, so start dates can still move.
There are two separate policies involved, and they are often confused. The company installing your roof should hold public liability insurance, which is broad cover for the company and its work. Impact Roofing Solutions holds this, and any established roofing company should. Most insurers require you to notify them when renovation work, or work of significant value, is being carried out on your property, and they will usually ask you to take out contract works insurance for the duration of the project. It is best thought of as a top-up: your ordinary house policy covers the everyday risks, and contract works covers the additional risk that comes with the work itself. So before a roof replacement starts, contact your insurer, arrange contract works cover and give us a copy of the certificate. We will provide our public liability details for your records at the same time. If you are unsure what cover you need, your insurer or insurance adviser is the right person to ask.
Most roof replacements do not require a building consent, but it depends on the circumstances of the work. Certain roof replacement work is exempt under Schedule 1 of the Building Act. As an example, Building Performance guidance identifies replacing an old clay tile roof with a profiled metal roof in the same position as work that can be exempt. Exempt is not the same as compliant: the Building Code still applies in full whether or not a consent is required. Where a project involves structural change, weathertightness issues or work beyond a straightforward replacement, a consent may be needed. We have written about this in detail in our blog post on whether a reroof needs a building consent, and if there is any doubt about your roof we will help you find out whether yours does. Because most roof replacements are exempt from consent, they are not restricted building work, which means no licence is legally required to carry them out and no council inspector checks the finished job. That is why it matters that the people actually on your roof are qualified roofers and Licensed Building Practitioners, who know what the work requires and are accountable for doing it properly.
