Asphalt Shingle Roofing Christchurch

Yes — the GAF shingles we install are BRANZ Appraised for extra-high wind zones, rated to 175–209 km/h, and perform well in both coastal salt spray and alpine freeze-thaw. The key is correct installation for NZ wind loads — which is why who installs them matters.

Honestly: it depends on your roof and taste. Long-run suits low pitches and lean budgets; shingles suit steeper pitches, complex roof shapes and homes where looks matter — and they are quieter in rain. We install both, so you get a straight recommendation, not a sales pitch for the only thing we sell.

A shingle roof is a system: substrate, underlayment, ventilation, valleys and flashings. Skip or shortcut any layer and the roof fails early — and the manufacturer warranty can be voided by improper installation. Trained shingle installers protect both the roof and the warranty.

It means our installers are approved and trained on GAF shingle systems, and we fit them to the manufacturer’s specification — substrate, underlayment, ventilation, valleys and flashings as one package. That matters to you twice over: the roof performs the way it was engineered to, and your material warranty stays valid, because improper installation is the quickest way to void it. We register that warranty with the New Zealand supplier once the job is finished.

Usually the old roofing comes off so we can check the structure and lay a proper substrate — that is what protects your warranty. We will tell you exactly what your roof needs after we have seen it, before you commit to anything.

The materials carry a 40-year-to-lifetime manufacturer warranty which we register with the NZ supplier on completion, and our own workmanship is covered for 10 years — both in writing.

Most homes take around 4 to 7 days depending on size, pitch and substrate work. You get a clear timeline in your quote, and the roof is closed up weathertight at the end of every day.
