2026 Reroofing Update
Residential construction prices rose just 0.1% in the September 2025 quarter (Stats NZ Value of Building Work Put in Place: September 2025 quarter). Overall residential building volume increased 2.8% seasonally adjusted, showing modest stabilisation after earlier slowdowns.
This means 2026 is a good time to lock in quotes before any potential rebound in material and labour costs. Our calculator ranges are based on current Auckland pricing, but always confirm with a free site visit for your exact roof.
A well-maintained roof helps you maintain a comfortable living environment throughout all seasons. It protects you against the elements, keeping you warm in winter and cool in summer. This way you spend less on additional heating and cooling systems, making a well-maintained roof a wise investment. Additionally, a well-maintained roof provides a healthy environment for your home by preventing the buildup of moisture and mold.
When it comes to roof maintenance, one important aspect to consider is reroofing. Over time, roofs can become damaged or worn, which can compromise their ability to protect your home. Reroofing involves replacing the existing roof with a new one, providing enhanced protection and insulation for your home.
Real Energy & Moisture Benefits (Backed by Official Guidance)
A new, properly sealed roof reduces heat loss and gain through the building envelope and stops leaks before they cause interior damage.
EECA guidance on home energy efficiency highlights that improving the roof envelope (along with basic insulation) helps lower heating and cooling costs in New Zealand homes. In Auckland’s humid climate, this also prevents mould and condensation issues that can affect health and resale value.
Take me straight to Reroofing Cost Calculator below
There are several factors to consider when calculating the cost of reroofing, including the size and complexity of the roof, the type of roofing material, the cost of labor, and any permits or fees required by your city. To get a better idea of the cost of reroofing your home, use the Reroofing Cost Calculator below.
What factors determine the cost of reroofing/roof replacement?
Type of roofing material (asphalt, metal, tile, etc.) Size of roof area Roof pitch/slope Amount of existing damage or wear Amount of decking and insulation replacement needed Complexity of the roof design and structure Removal and disposal of old roof materials Permits and fees Labor costs and access requirements (e.g., scaffolding)
How Roof Pitch and Access Affect Your Final Price
- Low-pitch roofs (under 20°) → standard labour rates.
- Steep pitches (30°+) or complex designs (valleys, dormers) → 30–80% higher labour due to safety harnesses and extra staging.
- Hilly or multi-level Auckland sites (e.g., Titirangi, North Shore, Waitākere) → scaffolding often adds $2,000–$8,000.
We measure pitch and access on every site visit so the quote you receive is realistic from day one.
How much does reroofing/roof replacement cost?
The cost of reroofing/roof replacement varies depending on the factors mentioned above. On average, homeowners can expect to spend anywhere from $5,000 to $12,000 for a basic asphalt shingle roof replacement on a standard-sized home. However, costs can easily escalate to $20,000 or more for larger homes, complex roof designs, or premium roofing materials such as metal or tile.
If you’re planning to install a new roof for your home in New Zealand, it’s essential to know the average cost involved. The new roof cost NZ can vary depending on various factors such as the type of roofing material used, the size of your roof, and the complexity of the installation process. On average, a new roof for a typical Kiwi home can cost between $10,000 and $25,000, with metal roofing being the most popular choice. However, keep in mind that other roofing materials like asphalt shingles, clay tiles, and concrete tiles can cost more. To get an accurate estimate of the cost of a new roof, it’s best to consult with a professional roofing contractor who can provide you with a detailed quote based on your specific requirements.
Material Choice: Upfront Cost vs Lifetime Value (2026)
| Material | Typical Cost Range (standard Auckland home) | Expected Lifespan | Approx. Replacements over 60 years | Best For in NZ |
|---|---|---|---|---|
| Asphalt Shingles | $5,000 – $12,000 | 15–20 years | 3–4 | Budget, low-pitch suburban |
| Metal Longrun / Corrugated | $10,000 – $25,000 | 40–50+ years | 1–2 | Windy, rainy Auckland & coastal |
| Concrete / Clay Tile | $15,000 – $30,000+ | 50+ years | 1 | Traditional Kiwi look |
| Slate | $25,000+ | 75–100+ years | 1 | Premium / heritage homes |
Metal roofing is the most common choice in Auckland because its longevity often makes it cheaper over the life of the home.
Important: Pre-1980s Roofs & Asbestos (WorkSafe NZ)
Many roofs installed before the mid-1980s contain asbestos (especially pressed metal tiles or bitumen-based products).
According to WorkSafe New Zealand guidelines:
- Asbestos-containing materials must be identified and removed only by licensed asbestos removalists when disturbed.
- Testing and safe removal add $3,000–$15,000 depending on roof size and condition.
We always recommend testing before any quote on older homes — this is a standard part of our free site assessment.
Tips to reduce the cost of reroofing/roof replacement for your home:
Choose a basic roofing material such as asphalt shingles instead of premium materials such as metal or tile. Schedule your reroofing/roof replacement during the off-season to take advantage of discounted pricing and more flexible scheduling.

Do You Need Building Consent for a Reroof? (Official Rules) From building.govt.nz (Schedule 1 of the Building Act 2004):
Most straightforward like-for-like roof replacements (same position, comparable materials) are exempt from building consent under exemption 1 (general repair, maintenance, and replacement), provided the original roofing has already met its minimum durability requirement (typically 15+ years for many materials).
Consent is required if:
- You are changing the roof type, pitch, or weight (e.g., asphalt to concrete tiles)
- Structural alterations or new penetrations are involved
- The existing roof has failed to meet the Building Code (e.g., ongoing leaks)
We check this for every Auckland job so you avoid unnecessary delays or fees.
Keep Your New Roof Performing for Decades Simple annual care dramatically extends lifespan:
- Year 1: Full clean and flashing check after installation.
- Every year: Clear gutters, inspect after storms.
- Years 3–5: Re-seal penetrations and touch-up coatings (metal roofs).
- Year 10+: Professional inspection.

How much does it cost to reroof a house?
The cost of reroofing a house can vary depending on factors such as the size of the roof, the type of roofing material used, and the complexity of the roof design. On average, you can expect to pay anywhere from $12,000 to $19,000 or more for reroofing a standard-sized home.
Is it better to repair or replace a roof?
The decision to repair or replace a roof depends on several factors, such as the age and condition of the roof, the extent of damage, the cost of repairs versus replacement, and the long-term goals of the homeowner. In general, if the roof is relatively new and the damage is minimal, repairing the roof may be the most cost-effective option. However, if the roof is old and has significant damage, replacement may be a better choice. A new roof will provide better protection against the elements, improve energy efficiency, and increase the value of the home. Additionally, if the repairs needed are extensive or the damage is widespread, it may be more cost-effective to replace the roof rather than continue to make repairs that will only provide temporary solutions. A professional roofing contractor can assess the condition of the roof and provide recommendations for repair or replacement based on the specific circumstances of the situation. Ultimately, the decision to repair or replace a roof should be based on the specific needs and goals of the homeowner, as well as the advice of a qualified professional.
How long does reroofing typically take?
The duration of a reroofing project can vary depending on the size and complexity of the roof, as well as the weather conditions during the installation process. On average, a reroofing project can take anywhere from a few days to several weeks to complete.
What are some common types of roofing materials used for reroofing?
Some common types of roofing materials used for reroofing include asphalt shingles, metal roofing, tile roofing, and slate roofing.
How can I get an estimate for the cost of reroofing my home?
You can get an estimate for the cost of reroofing your home by contacting a roofing contractor in your area and requesting a quote. They will typically come to your home to assess the roof and provide you with an estimate based on the factors mentioned earlier.
Can I save money by reroofing my home myself?
Reroofing is a complex process that requires specialized skills and equipment, so it is not recommended for homeowners to attempt it themselves. It is often more cost-effective to hire a professional roofing contractor who can get the job done safely and efficiently.
