The first big southerly of the season hit Botany hard last year, and by 9pm our neighbour had a brown stain spreading across her hallway ceiling like spilled tea. She rang in a panic asking whether to call a roofer or a plumber at that hour. The honest answer: at the height of a storm, in the dark, you don’t call anyone onto a wet roof. You contain the damage inside and get up there safely once the weather clears. Here’s the order I’d work through, because it’s the same order I use every time.
I’m Grant Pearce, and I’ve spent the last 19 years repairing roofs and chasing storm leaks across East Auckland — Botany, Dannemora, Golflands, and the older weatherboard streets of Howick and Pakuranga. I’ve stood in enough flooded hallways at 9pm to have a fixed routine by now, and none of it starts with a ladder in the dark.
Key takeaways
- In the dark, at the height of a storm, nobody goes onto the roof — you contain the water inside and get up there once it clears.
- Kill the power to any room where water is tracking near light fittings or downlights before you do anything else.
- The ceiling stain is almost never under the hole — water runs along the framing and drips out metres from where it got in.
- A callout and minor repair — flashings, screws, a valley clear — typically runs $250–$600 incl. GST; after-hours adds a premium.
- Sudden storm damage is usually covered; gradual deterioration usually isn’t — so photograph everything and get the cause in writing.
- Let a wet ceiling dry fully — a fortnight or more in Auckland — before you patch and paint, or the stain bleeds straight back.

What to do before the roofer even shows up
The first hour is about damage control, not diagnosis. You’re not trying to find the leak or fix it in the dark — you’re stopping the water that’s already inside from wrecking more than it has to, and keeping everyone safe while you do. It’s the order I run through with anyone who rings mid-storm.
- Kill the power to affected rooms: water tracking along a ceiling can reach light fittings and wiring. If a fitting is dripping or the ceiling is bulging near a downlight, switch that circuit off at the board before anything else.
- Catch and contain: buckets under the active drips, towels down, and move furniture and electronics clear. A plastic drop sheet over a bed or couch saves more than it costs.
- Relieve a bulging ceiling: a ceiling holding a pool of water can collapse. Pierce it with a small screwdriver at the lowest point of the bulge and drain it into a bucket. A neat 5mm hole is far cheaper to fix than a whole gib sheet coming down.
- Photograph everything: timestamped photos of the water, the stains and any ruined contents are what your insurer will want. Do this before you clean up.
- Note the time and conditions: wind direction and rainfall matter for a claim, and for whoever ends up diagnosing where it got in.
What you don’t do is climb onto a wet, wind-loaded roof in the dark. More Aucklanders end up in Middlemore from ladder and roof falls during storms than from the storms themselves. WorkSafe treats roof work as high-risk for good reason, and a leak that’s already inside your ceiling cavity won’t get dramatically worse in the few hours it takes for the weather to pass.
Temporary fixes that buy you time until daylight
Once the drips are caught and the power’s dealt with, a few make-safe measures genuinely help — and a few do more harm than good. None of them are worth a trip onto a wet, wind-loaded roof. Everything below you can do from inside, or at most from ground level once the wind eases.
| Situation | What actually helps | What to avoid |
|---|---|---|
| Active drip through the ceiling | Bucket underneath, towels down, a drop sheet over furniture | Leaving a full bucket to overflow — empty it before it does |
| Ceiling bulging with trapped water | Pierce the lowest point with a screwdriver and drain into a bucket | Leaving it be — a gib sheet full of water can let go all at once |
| Water near a light or downlight | Switch that circuit off at the board | Touching a wet fitting or flicking it back on before it’s dried and checked |
| Wind driving rain under a door or window | Towels and a rolled sheet along the sill to catch and channel it | Sealing it shut in a panic — it still needs to drain and dry |
| Roof access once the wind eases (daylight only) | A weighted tarpaulin lashed over the area and fixed at the ridge | Climbing a wet roof alone, in the dark, or in gusts — wait for a still, dry window |
A tarpaulin is the classic temporary fix, and it works — but only if it’s anchored over the ridge so the wind can’t lift it, and only if getting up there isn’t more dangerous than the leak. If you can’t do it safely, don’t: a few buckets and a dry night indoors is a fine result until someone can look at it properly.
Why the stain is never where the water got in
Here’s the part that catches most homeowners out: the wet patch on your ceiling is almost never directly under the hole. Water runs along the underside of the roofing, tracks down a rafter or a purlin, and drips out metres from where it actually entered. On Botany’s newer subdivisions the usual suspects are lifted or under-driven roofing screws with perished rubber washers, split or blocked flashings around chimneys and vents, and valleys clogged with leaves that back water up under the sheets.
On the older villas and bungalows around Howick and Pakuranga, it’s more often cracked mortar bedding failing on the tile ridge capping, or a valley iron that’s rusted through after years of quietly holding on. Wind-driven rain during a Botany southerly gets under laps and flashings that shed water fine in ordinary weather, which is why some roofs only ever leak in a storm. My usual approach is to run a hose methodically down the roof, section by section, while someone watches from inside — slow, but it’s the reliable way to pin down the true entry point rather than guessing and re-sealing the wrong spot.
That’s also why I’m wary of anyone who climbs up, squirts sealant at the nearest visible gap and calls it done. If it lands anywhere but the real entry point the leak just carries on, with silicone now hiding the evidence for whoever looks next. Finding the true source takes patience — a hose test, a look in the cavity for the track marks on the timber, and reading the roof for where a southerly drove the rain.
What the fixes cost in 2026
A callout and minor repair — resealing flashings, replacing a handful of screws and washers, clearing a valley — typically runs $250 to $600 including GST. Emergency after-hours callouts carry a premium, often $150 to $300 on top, which is one more reason to wait for daylight and normal rates if the leak is contained.
| Repair | Typical cost (incl. GST) |
|---|---|
| Callout + minor repair (flashings, screws, valley clear) | $250–$600 |
| After-hours emergency callout premium | +$150–$300 |
| Reseal or replace flashing | $300–$900 (depending on length/access) |
| Section of valley iron replaced | $600–$1,500 |
| Re-bed and re-point tile ridging | $80–$120 per lineal metre |
| Interior ceiling repair (gib, stopping, repaint) | $400–$1,500 per room, once fully dried |
Don’t rush the interior repairs. A ceiling needs to dry fully, sometimes a fortnight or more in Auckland’s humidity, before you patch and paint, or the stain bleeds straight back through. If your roof is showing its age across the board rather than failing at one point, it’s worth reading up on the signs your roof needs repair before winter rather than patching leak after leak, since a roof that keeps needing spot repairs is usually telling you it’s closer to a full re-roof than another round of tuckpointing on the ridge caps.
What your insurance will and won’t cover
Most house policies cover sudden storm damage but not gradual deterioration. That distinction matters: if an assessor decides the leak came from a roof that was obviously past its life, the claim can be declined. Keep your photos, keep the roofer’s written report on the cause, and lodge the claim promptly. Emergency make-safe work to prevent further damage is usually covered, but check with your insurer before authorising anything major.
The wording that trips people up is “sudden and accidental” versus “gradual”. A storm ripping a flashing loose is sudden; a valley iron that’s been quietly rusting for a decade is gradual, and an assessor who spots perished washers and moss-packed valleys can argue the damage was always coming. That’s why the cause of the leak matters to an insurer as much as the storm that triggered it.
A few things stack the odds in your favour. Lodge the claim quickly, before the ceiling dries and the evidence goes. Keep receipts for any make-safe work — buckets, a tarpaulin, an emergency callout — since reasonable steps to prevent further damage are usually claimable. Ask the roofer to spell the cause out plainly in writing, since a clear one-page report tends to carry more weight than a folder of blurry photos. And check your excess first — on a small touch-up it can eat most of the bill, whereas a ceiling and ruined contents into the thousands almost always clears it.
When a leak means more than a repair
Most storm leaks are a spot repair and nothing more — one flashing, a run of screws, a blocked valley. But every so often a storm exposes a roof that was already near the end of its life, and it’s worth being honest about which of the two you’re looking at.
The tell-tales I watch for are failure in more than one place at once, fixings corroded right across the roof rather than at a single spot, ridge capping crumbling along its whole length, or a coating so chalked and flaking that the metal is exposed wherever you look. At that stage, patching one leak just moves the problem along — the next southerly finds the next weak point, and you pay callout after callout for what one re-roof would settle. If yours is ageing broadly rather than failing at one clear point, that’s a conversation worth having before another wet winter.
Questions I get asked after a storm
Should I go up on the roof myself during a storm? No. A wet metal or tile roof in strong wind is genuinely dangerous, and a contained interior leak won’t get much worse over a few hours. Deal with the water inside, cut the power if fittings are affected, and wait for the weather to clear before anyone gets up there.
Why is the ceiling leaking a long way from where the water gets in? Water runs along the underside of the roofing and down the framing before it finds a low point to drip through. The stain marks where it fell off the timber, not where the roof failed. That’s why locating the true entry point often takes a methodical hose test rather than a guess.
How much does storm roof repair cost around Auckland? For a straightforward job — resealing flashings, a few screws, a valley clear — budget $250 to $600 including GST, or more if it’s an after-hours callout. Bigger jobs like a valley iron section or tile ridge re-bedding run into the thousands; see the cost table above for the breakdown I quote most often.
Should I repair the leak or re-roof the whole house? If it’s one flashing or a stretch of valley iron, a spot repair is the right call. If I’m finding multiple failure points, corroded fixings across the whole roof, or ridge capping crumbling in several places, patching becomes false economy and I’ll say so — that’s usually a re-roof conversation, not another repair invoice.
What roofing materials suit Auckland’s older villas and bungalows? A lot of the housing stock around Howick and Pakuranga built between the 1930s and 1960s was laid with clay or concrete tile, which needs its ridge capping re-bedded and re-pointed periodically rather than replaced outright. Long-run metal roofing, common on Botany’s newer builds, is generally lower-maintenance but lives or dies on its flashings and screw fixings — which is exactly where storm leaks tend to start.
Whatever’s dripping tonight, the order matters more than speed: make it safe inside, cut the power if a fitting’s involved, stay off the roof while it’s wet and windy, photograph everything for the claim, and get someone up there in daylight to find the real entry point. Done in that order, a frightening night usually turns into a straightforward repair. Then book the inspection for a dry day rather than the same night — an Auckland roof repair contractor can find the entry point properly once the surface is safe to walk.
