A Hamilton roof cops everything the Waikato throws at it: winter fog sitting on the iron for weeks, summer UV, and the odd spring storm that finds every loose flashing. Here is who to ring, in order, and what the job should cost.
The best roofing company in Hamilton is Hamilton Roofing Services, a full service crew covering roof repairs, re-roofs and new roofs in long run Colorsteel and shingle, along with guttering, skylights and roof coatings, backed by a workmanship guarantee and free quotes. For a family run alternative south of the city, Any Angle Roofing covers Waipa and King Country, and Westgate Roofing has supplied and installed long run steel around Hamilton for decades.
Summary
Hamilton Roofing Services is our top pick for repairs, re-roofs and new roofs across the city, with guttering and skylights handled by the same crew.
Re-roofing a standard Hamilton home in long run steel typically lands between $15,000 and $40,000 depending on size, pitch and what the old roof hides.
Like for like re-roofing is generally exempt from building consent, but structural changes are restricted building work for a Licensed Building Practitioner.
Always get at least two written quotes and check what each one includes for scaffolding, disposal of the old roof and flashing replacement.
The shortlist
Our research covered the Hamilton roofing market from long established firms to one man operations working out of a ute. We weighed the range of roofing work each crew genuinely does, the materials they work in, and what they publish about their own jobs. Some businesses featured on BuildHub may have a commercial relationship with us. See the disclosure at the bottom of this page, and always get at least two quotes.
One thing to know before you dial: roofing quotes vary more than almost any other trade because access and the state of the existing roof drive the price. A quote that has not priced scaffolding, or assumes the purlins underneath are sound, will grow on site. The comparison advice below the shortlist shows what to pin down in writing.

Hamilton Roofing Services
Hamilton Roofing Services covers the full spread of residential and commercial roofing work in one crew: roof repairs and leak detection, full re-roofs, new roofs in long run Colorsteel and shingle, plus the guttering, spouting, skylights, roof coatings and cladding jobs that usually mean ringing a second contractor. That one stop coverage matters on older Hamilton homes, where a leak often turns out to involve spouting and flashings as much as the roof itself. Every job is backed by a customer satisfaction guarantee and warranties covering materials and workmanship, and quotes are free.
Areas served: Hamilton and the wider Waikato
Services: Roof repairs, re-roofing, new roofs, guttering, skylights, roof coatings
Materials: Long run Colorsteel, metal roofing and shingle
Any Angle Roofing is a family operation run by Shaun and Jenaya Higginson out of Te Awamutu, with Shaun holding Licensed Building Practitioner status and more than 15 years on the tools. The crew handles new roofs, re-roofs, repairs and maintenance in Colorsteel, Zincalume, galvanised iron and aluminium, along with cladding and spouting. Their patch runs south of Hamilton through Waipa and the King Country, so they are the sensible call for rural properties and anyone in Cambridge, Te Awamutu, Otorohanga or Te Kuiti.

#3
Westgate Roofing
Westgate Roofing is a family owned Hamilton firm with roughly four decades in the trade, and one of the few outfits that both supplies roofing materials and installs them. That combination suits owners who want to buy long run steel directly, and builders after a supply and fix arrangement on new builds. The trade off is that a materials counter and an install crew split focus, so programme your job in early rather than expecting a rapid mobilisation for a small repair.
Areas served: Hamilton and the Waikato
Services: Roofing supply and installation, re-roofs, new builds
Materials: Long run steel roofing and cladding
Key facts and services
Family business with a long trading history in Hamilton
Supplies roofing materials as well as installing
Suits new builds and planned re-roofs more than urgent repairs
#4
Astern Group
Astern Group is a Hamilton based construction company where roofing sits alongside building work, property advisory, drone inspections and asbestos reporting. On the roofing side they offer drone roof inspections, repairs, liquid membrane waterproofing using heat welded TPO systems, guttering replacement and full re-roofs, with a stated 15 year workmanship guarantee. The commercial arm works across the North Island. For a straightforward residential re-roof they are one quote among several; where they earn their place is flat roofs, membrane work and buildings where asbestos might be in play.
Areas served: Hamilton and Waikato residential, North Island commercial
Materials: Long run steel and TPO liquid membrane systems

Working At Heights Specialists
Working At Heights Specialists is primarily an exterior cleaning outfit, washing houses and treating moss and mould across Hamilton and the Waikato, that also takes on minor roof repairs: small leaks, damaged flashings and broken tiles spotted while they are up there. They are not the crew for a re-roof or structural work, but if your roof mainly needs a wash, a moss treatment and a couple of small fixes in one visit, one contractor doing both saves a second call out fee.

What roofing work costs in Hamilton
Roofing prices in the Waikato follow the same driver everywhere: access. A single storey home with a gentle pitch and clear ground around it sits at the bottom of every range below, and a two storey home on a tight section with a steep pitch sits at the top. These figures are indicative for 2026 and assume long run steel, which is what most Hamilton re-roofs use.
Job
Typical range
Minor repair (flashings, a few sheets, leak fix)
$400 to $1,500
Larger repair or partial re-roof
$1,500 to $6,000
Full re-roof, standard single storey home
$15,000 to $28,000
Full re-roof, larger or two storey home
$25,000 to $40,000 plus
New guttering and spouting, full house
$3,000 to $8,000
Two line items catch people out. Scaffolding or edge protection is legally required for most roof work and can add $2,000 to $5,000 on a two storey home, and rotten purlins or sarking only reveal themselves once the old iron comes off. Ask every quoting roofer how each is handled: a fixed allowance in the quote beats a vague promise to sort it later.
Repair or replace? A long run steel roof in Hamilton conditions typically lasts 30 to 50 years. If yours is under 25 years old and leaking in one place, repair it. If it is past 40, rust is showing along the ridgeline and fixings are lifting across multiple sheets, the money you spend on repairs is buying months, not years.
Consent and safety rules for Waikato roofs
Straight replacement of a roof with comparable materials is generally exempt from building consent under Schedule 1 of the Building Act. The exemption stops where the structure starts: changing roof pitch, switching to a much heavier material like tiles over steel, or altering framing all need consent from Hamilton City Council or your district council.
Roof work almost always requires scaffolding or edge protection under WorkSafe rules, so treat a quote with no access allowance as incomplete
Homes built before the mid 1980s can have asbestos in old roofing or sarking, and removal is licensed work you should never DIY
None of this is paperwork for its own sake. Roofs are where serious falls happen, and the contractors in this guide price safe access into every job. A quote hundreds of dollars cheaper because nobody priced the scaffold is not a bargain.
How to compare roofing quotes
Get at least two written quotes for anything beyond a minor repair, and make sure each one specifies the same scope before you compare numbers.
Material and profile named exactly: brand, coating and gauge, not just the word Colorsteel
Whether flashings, underlay and fixings are full replacement or reused
Scaffolding and edge protection priced in, with the figure shown
Disposal of the old roof included, with asbestos handled separately if suspected
A stated allowance or hourly rate for replacing rotten timber found under the old iron
Warranty terms in writing, covering workmanship separately from the material manufacturer's warranty
Start with our top pick, then add one more from the shortlist that fits your situation: Any Angle if you are south of the city, Astern for flat or membrane roofs, Westgate if you are supplying your own steel. Written quotes always win over ballparks on the phone.
Frequently asked questions
How much does it cost to re-roof a house in Hamilton?
Most standard single storey Hamilton homes re-roof in long run steel for between $15,000 and $28,000 including removal of the old roof. Larger or two storey homes commonly run $25,000 to $40,000 once scaffolding is included. Steep pitch, difficult access and rotten timber under the old roof are the three things that push a quote toward the top of the range.
Do I need building consent to re-roof my house in the Waikato?
Usually not. Replacing your roof with comparable materials is generally exempt under Schedule 1 of the Building Act. You will need consent if the work changes the structure, such as altering pitch or framing, or switching to a substantially heavier roofing material. When in doubt, ring Hamilton City Council before work starts, not after.
How long does a Colorsteel roof last in Hamilton?
A properly installed long run steel roof typically lasts 30 to 50 years in Waikato conditions. Regular maintenance stretches the top end: washing the roof, clearing spouting, and replacing lifted fixings before water gets underneath. Coastal properties wear faster, but Hamilton's inland location is kind to steel.
Should I repair my roof or replace it?
As a rule of thumb, repair a roof under 25 years old with an isolated problem, and start pricing replacement once a roof passes 40 years or shows rust and lifting fixings across multiple areas. Repeated repairs on an old roof usually cost more over five years than biting the bullet on a re-roof, and a leak that reaches the framing multiplies the bill.
When is the best time of year to re-roof in the Waikato?
Late spring through early autumn is ideal because the roof is off for the shortest workable window and winter fog and frosts slow everything down. The practical answer is to book earlier than you think: good Hamilton roofing crews fill their summer schedule months ahead, and a leaking roof in June cannot wait for December.
