Signs You Need a Roof Replacement
Most Wellington roofs give you a 30–50 year run before replacement becomes the right call. Here are the red flags:
- Widespread rust across long-run steel — not just isolated spots
- Cracked or slipped tiles in multiple areas
- Sagging ridge line or visible dips between rafters
- Failed underlay (water entering even with the roof skin intact)
- Repairs becoming more frequent than every 2–3 years
- Roof is past 30 years old on tile, or past 25 on unpainted galv
If you’re not sure, book a free inspection. We’ll tell you whether a repair will do, or whether it’s time to replace.
Profiles, Materials & Brands
We supply and install from NZ’s three major roofing suppliers — Colorsteel, Dimond and Roofing Industries — in every common Wellington profile:
- Flat Colorsteel roofing
- Corrugated iron long-run (galv and Colorsteel)
- Diamondek 400 and tray profiles
- Trapezoidal, 5-rib and rib-tray
- Concrete and terracotta tile
- Flat butynol and rubber membranes
- Asphalt and timber shingles
- Decramastic and pressed-metal tile
Not sure which profile suits your home, budget and wind zone? Our roof profiles guide walks through the trade-offs, or we’ll recommend during the quote.
Transparent Roof Replacement Costing
Ballpark numbers so you’re not going in blind. These are indicative ranges for a standard Wellington family home — final price depends on pitch, access, and whether structural work is needed.
- Basic re-roofing: ~$8,000–$15,000
- Mid-range: ~$15,000–$30,000
- High-end or complex: $30,000+
Every job is quoted fixed-price in writing before work starts. No hourly games, no mid-job surprises. If we find something that changes the scope (rotten dwangs, failed decking), we stop, tell you, and re-quote — your call whether to proceed.
Aerial photography and drone mapping available on request to make quoting more accurate.
Navigating Building Consents
Not every roof replacement needs a building consent. Here’s the quick rule.
No consent usually needed:
- Like-for-like replacement with same or similar material
- Existing roof has lasted beyond its 15-year durability requirement
- Switching to a lighter material
Consent required:
- Changing to a heavier material (e.g. tile to concrete tile on an un-reinforced structure)
- Structural alterations to trusses or dwangs
- Early failure (roof less than 15 years old)
- New openings — skylights, roof windows, vents
We handle the consent process end-to-end if it’s needed — paperwork, council liaison, sign-off.
Roof Safety and Access
Wellington hillsides and high pitches demand proper access. We use whichever system suits the job:
- SARNZ-compliant scaffolding — full re-roofs, long-duration jobs
- Rope access — quick repairs on steep or awkward sites
- Edge protection — harness-point installation, fall-arrest lines
- Cherry picker — chimney access, single-side elevations
- Aerial photography — drone mapping for accurate scope and quoting
Fully insured, SARNZ-compliant, working-at-heights supervised. Your insurer will be happy.
