Before you hire

Ask any roofing contractor for a written warranty on both materials and workmanship, confirm they carry public liability insurance, and request photos of recent comparable jobs before committing.

Before you hire a roofer in Hamilton
Drawn from 128 customer reviews collected for this page. The first answer is what it costs.
What does roofing work typically cost in New Zealand? expand_more
Re-roofing costs run from $80 to $200 per square metre for materials and labour, with corrugated steel (Colorsteel) sitting at the lower end. A standard NZ house of 150 to 200 square metres will land somewhere between $15,000 and $40,000 all up. One reviewer noted that long-run steel guttering came in considerably cheaper than replacing old PVC, so material choice affects the final number more than people expect.
How do I know if a roofer's recommended repairs are actually necessary? expand_more
Ask for a written inspection report with photos before you approve anything, so you can see the damage yourself rather than taking someone's word for it. A legitimate assessment will identify specific problem areas, explain why repair or replacement is needed, and give you the option to fix rather than replace where possible. Getting two or three independent opinions is the safest move, because some operators will recommend a full re-roof when targeted repairs would do the job.
What should a roofing quote include before I accept it? expand_more
A solid quote names the exact materials by product and grade, confirms whether old materials will be removed and disposed of, and spells out what happens with flashings and underlay. Reviews point to communication and transparency on costs as the clearest sign a contractor is worth hiring, with one reviewer specifically calling out having no surprise costs as a highlight. The quote should also state the timeline, a payment schedule, and whether a building consent is included, since full re-roofs require one under the Building Act.
What are the warning signs of a roofer you shouldn't hire? expand_more
- –A contractor who takes weeks to respond to messages or goes silent after you accept a quote is a serious red flag.
- –Showing up late to a quote appointment and being unprofessional in person suggests the same attitude will carry through to the work.
- –Watch out for vague or verbal-only quotes that leave costs open to change once work is underway.
- –One reviewer paid out of pocket for a repair that should have been covered, because the contractor denied responsibility for damage caused on site.
- –Crew behaviour on site matters, as neighbours of job sites have reported loud, intimidating conduct that management failed to control.
- –Capacity problems are worth asking about upfront, since at least one Hamilton operator turned away re-roofing work due to not having enough staff.
What should you ask before hiring a roofer? expand_more
- –Ask whether they hold a current Licensed Building Practitioner (LBP) Roofing licence and request their LBP number so you can verify it on the MBIE register.
- –Ask exactly what the quote includes: materials by brand, disposal of old roofing, flashings, underlay, and guttering.
- –Ask what their process is if they find additional damage during the job, and whether any extra costs require your written approval before work proceeds.
- –Ask what workmanship warranty they offer and get it in writing, not just a verbal assurance.
- –Ask whether they will handle the building consent, since re-roofing requires one and the responsibility for obtaining it should be confirmed before work starts.
- –Ask for references from recent re-roofing jobs, not just repairs, so you can speak to someone whose project was a similar scale to yours.

How are the top roofers in Hamilton chosen? expand_more
We build this page from Google Maps results for roofers in Hamilton. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
What does a business subscription offer? expand_more
No business can pay for a place in these rankings. Claiming and verifying a listing is free. It adds a phone number to the card and a small trust bonus (+3 points) to its score, for confirming a real operator stands behind the listing. The owner also gets a dashboard showing how their score is made up. A paid subscription provides an enhanced card with more ways to reach the business, including a website link and a detailed profile page. It also refreshes this page monthly and adds ranking history and competitor analysis to the owner's dashboard. The subscription adds nothing to the score. Claim your listing or see what a subscription includes.
Why isn't my business listed? expand_more
We build this page from Google Maps results for roofers in Hamilton. The usual reasons for missing out are a Google Business category that does not match, too few reviews to score near the top, or an address outside the area we cover. Sometimes we miss a business that should be here. Check where you rank first. If you are not there and think you should be, get in touch.
