Restore or Replace? Deciding on a 1970s Roof in Lower Hutt

26/10/2026 · 5 min read

Suburbs like Naenae, Taita, Stokes Valley and Waiwhetū were largely built out in the 1950s to 1970s, and many of those houses still have their original iron or concrete tile roofs. After fifty-odd years of Hutt Valley weather, owners often ask the same question: is this roof worth saving, or is it time for a new one?

Before deciding, it helps to understand what a roof restoration involves, step by step: a thorough clean, repairs to any failed fixings, flashings or tiles, then a primer and topcoats suited to the roof. Roof Repair Wellington says most of the jobs it is called to are solved with a targeted repair or restoration rather than a full replacement, so it is worth getting the roof assessed properly before assuming the worst.

Signs a roof is a good restoration candidate

Iron that is faded or chalky but still solid when pressed at the laps
Rust limited to surface spotting rather than holes
Concrete tiles that are porous but mostly uncracked
Battens and purlins that are dry and firm
Leaks traced to specific flashings or fixings rather than the whole roof

Signs replacement may be the better call

Rust that has eaten through sheets, especially along laps and gutters
Widespread cracked or crumbling tiles
Soft or rotten timber under the roofing
Repeated leaks in different places every winter
A roof that has already been recoated several times and is failing again

Why the timber matters as much as the roof

A new coating cannot fix what is underneath. If a roofer finds that purlins have rotted where water has been getting in for years, those need sorting first. On older Hutt homes with long-run iron over sarking, it is common to find a mix of sound and damaged boards. A good assessment from inside the roof space as well as on top will show which way to go.

Getting a fair comparison

When you get quotes, ask each roofer to explain what they found and why they are recommending restoration or replacement. Photos of the problem areas make it much easier to compare advice. A written quote that lists the repairs, the coating system and the number of coats gives you something solid to weigh up.

Timing in the Hutt Valley

Coatings need dry weather to cure properly, so restoration work is best planned for late spring and summer. The valley floor can be still and damp on winter mornings, which slows drying. If your roof is leaking now, a repair to stop the water can be done straight away, with the recoat booked for a settled spell later.
