Roof Installers Canterbury

Why local expertise matters

Canterbury’s dramatic temperature swings, Nor’west winds and occasional snowfalls present unique challenges for any roof. Hiring professional roof installers in Canterbury ensures your new roof not only looks sharp but also meets wind-zone, seismic and snow-loading requirements. Local crews know which fasteners resist sea-spray corrosion in Pegasus Bay, how to stage work around unpredictable southerly fronts and the council inspection process from Selwyn to Waimakariri.

Popular roofing systems installed

• Long-run steel – lightweight, fast to install and available in modern tray profiles ideal for both residential and commercial projects.
• Concrete or clay tiles – classic aesthetics, thermal mass and individual tile replacement capability.
• Membrane roofing – TPO, EPDM and torch-on systems for low-pitch or flat architectural designs.
• Slate & shingles – premium appearance, high durability and suited to character restorations.

How to compare roofing contractors

Shortlist at least three companies and request itemised proposals. Look for:

• Licenced Building Practitioner (LBP) numbers for roofing – a legal requirement for most re-roofing work.
• Proof of public liability insurance and SiteSafe practices.
• Detailed scope including underlay, flashings, penetrations, scaffolding and waste removal.
• Product and workmanship warranties of 15–30 years backed by the manufacturer.
• Recent local references you can visit.

All workmanship must comply with NZ Building Code clause E2, so ask how the installer achieves weathertight junctions at valleys, ridges and parapets.

Typical costs & timelines

As a rule of thumb, expect:

• Metal long-run re-roof: $110–$160 per m² installed, including removal of old roofing.
• Concrete tile reroof: $150–$220 per m² depending on pitch and batten condition.
• Membrane roofs: $140–$200 per m² for a warm-roof assembly.

Lead times fluctuate with seasonal demand and supply chains. Allow 2–3 weeks for fabrication of custom flashings and 3–5 days on site for an average 180 m² home.

The installation process step by step

Understanding the sequence helps you schedule other trades such as solar installers or painters:

• Step 1 — Site measure & ordering – the roofer confirms dimensions, pitch and flashing details before placing the factory order.
• Step 2 — Scaffolding & edge protection – erected to WorkSafe standards.
• Step 3 — Old roof removal – materials are stripped, sorted and recycled where possible.
• Step 4 — Structural inspection – rafters and purlins are checked for borer, moisture or sagging.
• Step 5 — Underlay & battens – breathable membranes and timber battens are installed to create a drainage plane.
• Step 6 — Roofing sheets or tiles – fixed in strict accordance with manufacturer torque and spacing requirements.
• Step 7 — Flashings & penetrations – custom-folded on site for a precise fit.
• Step 8 — Final QA & council inspection – LBP issues the Record of Work for Code Compliance Certificate.
• Step 9 — Site clean-up – magnetic sweep for nails and safe disposal of waste.

Consents & compliance in Canterbury

Most re-roofs that replace “like with like” to the same pitch do not require a building consent, but any change in material or structure usually does. Your installer should lodge documentation with the Christchurch City Council or relevant district authority and supply a producer statement if required. Ask who will manage the paperwork, pay council fees and attend inspections. Failing to obtain consent can void insurance, so make sure compliance is written into the contract.

Questions to ask before signing

• Who will be on site each day and is supervision provided by a senior roofer?
• What weather-tightness details are specified for skylights and solar penetrations?
• How are health & safety and fall-protection costs handled?
• Is scaffolding hire included in the fixed price?
• Can I see photos of roofs completed at least five years ago?
