Hauraki roofing: metal roof replacement from Paeroa to Whiritoa
CTR Roofing has been roofing in the Waikato since 2010, from our yard at 12A Empire Street in Frankton, Hamilton. We make the trip across Hauraki District to re-roof homes in COLORSTEEL MAXAM® longrun, and we also roof new builds from the plans, commercial buildings and farm sheds.

What we do
Roofing services across the district
Every roof is longrun steel in COLORSTEEL MAXAM®, in corrugate or trapezoidal rib, installed by LBP Roofing licensed installers.
Re-roofing
Old iron off, new longrun steel on. Most homes are re-roofed in 2–4 days once we're on site.
Metal roof replacement
New roofs
Quoted from the plans, with a start date that fits the build programme.
New roof installations
Spouting and downpipes
Added to your re-roof as a separate line. We don't do spouting on its own.

Where we roof
Plains, goldfields, gorge and surf
Hauraki District had 21,318 people at the 2023 census, across the Plains, Paeroa and Waihī wards. It runs from the Firth of Thames to the Bay of Plenty coast, so a roof at Kaiaua and a roof at Whiritoa have different things to deal with.
Paeroa and the gorge
Paeroa sits near where the Waihou and Ohinemuri rivers meet, at the crossroads of State Highways 2 and 26, and everyone knows the giant L&P bottle on the main road. It's sheltered most days, but NIWA's figures show more gusts over 96 km/h here than at the other Waikato weather stations it compares, so flashings and fixings matter as much as the sheets. East of town, the highway and the Hauraki Rail Trail head up through the Karangahake Gorge.

Waihī and the goldfields
Waihī grew up around the Martha Mine. The 1904 Cornish Pumphouse still stands beside the pit, the Goldfields Railway runs out to Waikino, and miners' cottages from those years are still part of the town. Corrugate keeps the look of an older home, and new steel weighs about the same as old iron.

Ngatea and the Plains
Canals and stopbanks turned the Plains into dairy country in the 1900s, and Ngatea, on the Piako River, became the service town for the farms around it. Out here a re-roof is often a farmhouse with a shed or two beside it. We roof both, in the same steel. See rural roofing.

Whiritoa and the coast
Whiritoa is a 1.5 km surf beach between Whangamatā and Waihi Beach, with 264 residents at the last census and over a thousand people at New Year. On the far side of the district, Kaiaua and Miranda look over the calmer water of the Firth of Thames. Salt is what shortens a roof's life on both coasts, so your warranty depends on how far you are from the surf. See steel roofs near the sea.

On tank water?
Tell us when you ask for a quote. BRANZ estimates about 10% of New Zealanders drink water collected from their roof, and factory-coated steel is among the materials it lists as suitable, though it says to check with the manufacturer. Its advice for a new roof is to wait for at least one good rainfall before reconnecting the downpipe to your tank, and to avoid collecting drinking water off uncoated lead flashings.
What a re-roof looks like
An old red iron roof, replaced in dark longrun
Old red iron off and new dark longrun on, on a brick home with a rural outlook. This one's a Waikato job rather than a Hauraki one, but it's the kind of change a home on the Plains or around Paeroa can expect.

What's different in Hauraki: travel
It's the same COLORSTEEL MAXAM® steel inland or by the sea, so the material price doesn't change. Because the crew and materials go further, we charge travel at Inland Revenue's business rate, currently $1.30 per km, for each trip there and back. Your quote shows the kilometres.
| From our Frankton yard to | Road distance | Return trip |
|---|---|---|
| Paeroa | 76 km | 152 km |
| Ngatea | 93 km | 186 km |
| Waihī | 96 km | 192 km |
| Whiritoa | 111 km | 222 km |
Road distances are approximate.
Hauraki weather
Rain, wind and salt: what your roof is up against
The figures below are from NIWA's climate guide to the Waikato. The Plains are among the drier parts of the region, the ranges behind them are among the wettest, and Paeroa gets stronger gusts than you'd expect from such a sheltered spot.
- 1,000–1,200 mmof rain a year on the Hauraki Plains, and over 2,000 mm in the Coromandel Ranges
- 31%of the year's rain falls from June to August, against 22% from December to February
- 1.6 daysa year with gusts over 96 km/h at Paeroa, against 0.2 at Hamilton
- 124 km/hhighest gust recorded at Paeroa, on 29 November 1998
People here remember the big ones. The April 1981 storm destroyed half of Waikino and flooded Paeroa, and the January 2018 storm surge brought the second-highest sea level recorded at Thames. A roof can't do anything about floodwater, but wind-driven rain is its job. Longrun sheets run from ridge to spouting with no joins down the slope, which leaves the flashings and fixings as the places to get right. See roof flashings explained.
A year on a Hauraki roof
Summer
The driest stretch, with one or two dry spells of 15 days or more most years between December and March. Whiritoa fills up at New Year, so talk to us early about a bach roof. The Paeroa Highland Games and Tattoo is at Paeroa Domain on 13 February 2027.
Autumn
Summer and autumn have the most light-wind days, and the dry spells can run into March. The holiday crowds have gone home from the beach. The Hauraki Games, a free community sports day at Paeroa Domain, was held in March this year.
Winter
The wettest months, and gales are most frequent in winter: 44% of Paeroa's strong winds come in these three months. Rain can add time to a re-roof, so allow a bit of slack in your plans.
Spring
Generally the windiest season across the Waikato, with winds strongest in the early afternoon. Getting a quote in now sets you up for a summer job. Paeroa's fireworks display was on 24 October this year.
Hauraki District Council
Consent, the Plains and heritage
Do you need a building consent?
Usually not, if it's like-for-like. Under the national building consent exemptions, you can replace a roof without consent when the new one is comparable to the old and goes in the same position. Changing the structure, pitch or shape can need consent. Hauraki District Council, based in Paeroa, points homeowners to its building page and the Can I Build It tool.
Building new on the Plains?
The council warns that the Plains sit on tens of metres of compressible estuarine sediment, which settles under load, and that settlement on fill generally follows the combined weight of the building and the platform. Your engineer sorts out the foundations. See building on the Hauraki Plains. We quote the roof from your plans.
A heritage building?
The Hauraki District Plan has its own historic heritage section and inventory, which includes gold-era buildings. If your property is listed, check with the council before changing the roof's material, profile or colour. A like-for-like re-roof in corrugate is the simplest place to start that conversation.
The steel
One steel, and your distance from the surf
Every job gets COLORSTEEL MAXAM®, which replaced Endura® and Maxx®. Paeroa, about 20 km from the Firth, and Waihī, about 10 km from Waihi Beach, are well inland. Whiritoa is where the distance matters. Calm firth water puts far less salt in the air than surf, but exposure can shift a site's category, so we'll confirm yours with the quote. More in COLORSTEEL roofs explained.
| Distance from surf, east coast | Corrosion, up to | Paint, up to |
|---|---|---|
| 5 km or moremild | 50 years | 18 years |
| 500 m–5 kmmoderate | 40 years | 18 years |
| 100–500 msevere | 30 years | 15 years |
| 25–100 mvery severe | 20 years | 15 years |
| Under 25 mextremely severe | We don't take on these sites | |
Warranty figures from COLORSTEEL. Rain washes most of the roof. Rinse the areas it doesn't reach, like under the eaves, to keep the warranty.
Before you get quotes
Hauraki roofing questions
Straight answers for homeowners, farmers and bach owners across the district.
Updated November 2026
Do you work in Hauraki if you're based in Hamilton?
Yes. Our yard is at 12A Empire Street in Frankton, about 76 km from Paeroa and 96 km from Waihī. We've been roofing in the Waikato since 2010, we're a RANZ member, and our installers hold LBP Roofing licences.
How much does metal roof replacement cost in Hauraki?
Most Waikato homes cost $18,000–$40,000 to re-roof in metal, or about $110–$220 per m² of roof, plus travel at $1.30 per km for each trip there and back. It's about 76 km from our yard to Paeroa and 96 km to Waihī, and your quote shows the kilometres. See the re-roof cost guide.
Do I need Hauraki District Council consent to re-roof?
Usually not for like-for-like, such as old iron to new steel in the same position. Changing the structure, pitch or shape can need consent. The national exemptions apply across the district, and the council's building page links to the Can I Build It tool.
Does a home at Whiritoa or Kaiaua need different steel?
No. We use COLORSTEEL MAXAM® on every job. What changes near the sea is the warranty, from up to 50 years against corrosion at 5 km or more from the surf down to 20 years at 25–100 m on the east coast. We don't take on sites within 25 m of the surf. See steel roofs near the sea.
What's the best time of year to re-roof in Hauraki?
December to March is usually the driest stretch, and summer and autumn have the most light-wind days. June to August is the wettest, and rain can add time to a job. If you want a Whiritoa bach done before New Year, talk to us early.
Can a new steel roof feed my water tank?
BRANZ lists factory-coated steel among suitable roof materials and says to check with the manufacturer. It advises waiting for at least one good rainfall before reconnecting the downpipe to the tank. Tell us you're on tank water when you ask for a quote.
Do you replace spouting and downpipes?
Yes, as part of a full re-roof or roof replacement. We don't replace spouting on its own. See gutters and downpipes.
How long does a re-roof take?
Most homes take 2–4 days on site. Rain, a two-storey home or rotten timber under the old roof can add time. See how long a re-roof takes and what happens in a metal roof replacement.
