Every week in Hamilton and across Waikato, homeowners call us for help with leaks, unfinished jobs, or roofing work that was never done to a safe standard. Most of these problems come from one cause: the roofer was not a RANZ Member and not a Licensed Building Practitioner (LBP).
Anyone can call themselves a roofer. But not everyone has the training, qualifications, or accountability that the industry expects. When a roof is installed by someone who is not qualified, the risk sits with the homeowner. There is no workmanship warranty, no compliance paperwork, and often no way to get the problem fixed without paying for the job twice.
Below are real stories from our region that show why using a RANZ and LBP roofer is not optional, it is essential.
A Hamilton homeowner paid a large deposit to a “roofer” who claimed they could replace their leaking shingle roof with longrun steel. The shingles were in poor condition, so the homeowner acted in good faith.
The installer removed most of the shingles and completed about 60% of the reroof. Then they realised the job was far beyond their skill level. They walked away, left the home partially exposed, and never returned.
The homeowner was left stranded:
A RANZ Member and LBP cannot behave like this. They are accountable to a Code of Conduct, trained to handle complex reroofs, and required to provide compliance documentation.
Another homeowner in Rototuna had lived with a leak for two decades. The cause? A basic installation error: no lap in the valley flashing.
This is a simple detail. Every trained roofer knows a valley needs a lap to keep water out. Without it, water can run straight under the roof and into the structure. The result was long-term water damage that could have been avoided on day one.
A LBP must follow the New Zealand Building Code and manufacturer specifications. They cannot skip details. Their work affects structural safety and must meet strict standards.
We recently inspected a reroof where the original hidden gutter should have been replaced. Instead, the installer left the old gutter in place and used a standard head flashing to hide it.
This is dangerous. Hidden gutters are a known risk area and require correct replacement during a reroof. Covering one up is not a repair—it is a shortcut. The homeowner thought they had a new, compliant roof. In reality, they had a concealed failure point that could cause major internal damage.
A RANZ Member follows industry best practice. They do not hide problems. They fix them and document them.
Many roofing failures come from one issue: the installer is not trained, not licensed, and not part of any professional organisation.
Some of the top-ranking roofing companies on Google in Hamilton appear to use:
High visibility online does not mean high-quality work. It simply means the website is ranking well. When things go wrong, these operators cannot provide warranties or legal documentation and can disappear without consequence.
When you use a roofer who is both RANZ and LBP certified, you get:
LBPs are licensed by the Building Practitioners Board. Their work must meet the Building Code.
RANZ Members follow a Code of Conduct. If something goes wrong, the Association can step in.
You receive the correct paperwork, including Records of Work for restricted building work.
Manufacturers will only honour warranties when approved methods are used.
You know who is on your roof, and you know their work is traceable.
A new roof is a major investment. Choosing the wrong installer can cost far more than the price of the job.
Before agreeing to any roofing work, check these three things:
Search the public register and confirm their licence is current.
RANZ membership shows they meet industry standards and operate ethically.
If the quote is vague, rushed, or avoids details, walk away.
