Signs your Christchurch roof needs replacing (what we find on inspections)

One failed flashing or valley is a repair. Water showing up in different rooms after rain from different directions usually means the cover is tired, not a single fault. That pattern is one of the clearest signs the roof needs replacing rather than another round of patches.

We trace each leak properly before recommending replacement. Sometimes two stains share one source. When they do not, a measured re-roof quote is often the honest answer.

Widespread rust around laps and screw lines, coating that cracks when walked, and sheets that move in nor'westers point to steel past economic repair. Nail-fixed iron often needs a re-screw first when the steel is still sound, but perforated or brittle steel cannot be saved by new screws alone.

On strip-back we check purlins and valley boards. Sagging, rot, or water damage must be cut out before new Colorsteel goes on. Hidden timber issues are why we inspect the deck, not just the sheets you see from the ground.

Roofs past roughly 40 years with brittle long-run or tired concrete tiles frequently reach end of life. A Fendalton home with its original 1960s roof was a clear replacement case: full strip, Karaka Colorsteel long-run, four days, tidy finish.

Homes with popped nails on lead-head or twisted-shank fixings may need a re-screw programme instead of a full re-roof. We tell you which camp you are in before you spend.

Bring photos of ceiling stains and note when leaks appear, wind-driven nor'west rain, steady drizzle, or only when valleys overflow each point to different faults.

We inspect on site and quote repair, re-screw, or full re-roof as separate options where they apply. You choose based on measured scope, not pressure toward the biggest job.
