A metal roof replacement (re-roof) in Perth makes sense when the sheeting has corroded through or the fixings and structure have failed — re-roofing starts at $170 per square metre. If the metal is sound but faded, a restoration at $22/m² is far cheaper. Metal replacement, usually to Colorbond, has been the most popular re-roof choice for Perth homeowners over the last 10–15 years.
Repair, restore or replace — which do you need?
It’s the question every homeowner with an ageing metal roof faces: patch it, paint it, or pull it off? The honest answer depends entirely on condition, and a good roofer will tell you what they’d do if it were their own home rather than pushing the biggest job.
A few leaks, loose sheets or failed screws usually means a targeted repair — the cheapest path. A roof that’s structurally sound but faded and tired calls for a restoration, cleaned and re-coated from $22/m². Widespread rust-through, perished fixings or a roof at the end of its life is where a full re-roof from $170/m² becomes the sensible spend.
Why so many Perth homes re-roof to Colorbond
When a metal roof does need replacing, the majority of Perth homeowners choose Colorbond, and it’s easy to see why: it’s light, comes pre-finished in 22 colours, and sheds Perth’s downpours fast. It’s also a chance to lighten the load on an old tile-framed home by switching from heavy tiles to steel.
That said, a re-roof is the moment to weigh Colorbond against Zincalume properly. At the same base metal thickness, Colorbond costs noticeably more — you’re paying for the coated, coloured finish. For a home, most people find it worth it; for a shed or a purely budget-driven job, Zincalume still stacks up.
What a re-roof actually involves
A re-roof isn’t just new sheets. The old roof is stripped and removed from site, the battens and sarking are checked and renewed where needed, and the new Colorbond or Zincalume is laid with correct fixings and flashings. If the timber framing has softened, that’s addressed first — sometimes with chemical delignification rather than a full re-frame.
Because it’s a bigger job, we measure and quote every re-roof after a free inspection so you know the exact figure and scope before committing. It’s backed by our 10-year workmanship warranty.
The one honest question to ask first
Before you spend on a new roof, ask: has the roof actually failed, or does it just look tired? A surprising number of “needs replacing” metal roofs are simply faded and dirty, and a restoration brings them back for a fraction of the cost. Speak to a professional, get the facts and the unbiased pros and cons of each option, and only re-roof when the roof genuinely warrants it.
