How to Check if Your Roofer Is Qualified (Before You Sign Anything)
Don’t Just Take Their Word for It — Check Their Credentials
When it comes to roofing, anyone can promise “quality work.”
But only licensed, insured, and qualified roofers can prove it.
Before you sign a quote or pay a deposit, it’s worth spending five minutes doing a quick background check.
It could save you thousands — and a lot of stress — down the track.
Here’s how to make sure your roofer is the real deal.
1️⃣ Check for a Licensed Building Practitioner (LBP) Number
Re-roofing and other work that affects structure or weathertightness is Restricted Building Work (RBW) under New Zealand law.
Only a Licensed Building Practitioner can carry it out or supervise it.
🔍 How to check:
Go to the LBP Register on MBIE’s website and search their name or company.
✅ You should see:
- A valid LBP number
- Roofing or building license class
- Current, active status
🚫 Red flag if:
They can’t produce an LBP number, or it’s expired or suspended.
2️⃣ Confirm They’re a Member of RANZ
The Roofing Association of New Zealand (RANZ) holds its members to high professional and ethical standards.
RANZ members are vetted for workmanship, insurance, and safety compliance.
🔍 How to check:
Visit ranz.co.nz and look for the company in the members directory.
If they’re not listed, ask why not.
3️⃣ Ask for Proof of Insurance
Roofing involves height, weather, and risk — and not all roofers are insured.
✅ Ask to see:
- Public Liability Insurance (covers damage to property or people)
- Professional Indemnity (covers design or advice work)
- SiteSafe / Health & Safety policies
If they hesitate or can’t produce documentation, that’s a clear sign to move on.
4️⃣ Ask Who’s Actually Doing the Work
Some roofing companies subcontract everything — meaning you don’t really know who’s on your roof.
✅ Ask:
- Are the installers in-house employees or subcontractors?
- Who will supervise the site?
- Will the LBP be present or sign off the work?
At Aquashield Roofing, every install is handled by our own trained, qualified crew — no random subs, no surprises.
5️⃣ Check Their Reviews and Project History
Google reviews, Facebook feedback, and before/after photos tell you how a company actually operates.
✅ Look for:
- Real local clients (not generic “great job!” comments)
- Photos of finished work, not just stock images
- Consistent 4.5 ⭐ + rating
If reviews mention communication issues or leaks after completion — take note.
6️⃣ Ask About Workmanship and Product Warranties
Good roofing companies back their work.
Ask for written proof of:
- Material warranty (Colorsteel / ColorCote typically 15–18 years)
- Workmanship warranty (5–10 years from the installer)
If they offer “no warranty but cheap price,” you already know what kind of job you’ll get.
✅ Final Word: Trust the Roofers Who Welcome Questions
Professional roofers are proud to show their credentials — they want you to check.
It means they’ve earned their place and stand by their reputation.
At Aquashield Roofing, every project is:
✅ Supervised by an LBP
✅ Completed by in-house RANZ members
✅ Fully insured and compliant
✅ Backed by written warranties
So if you’re comparing quotes, do your checks — and choose the company that meets every standard.
