Leaking Roof Repair

Finding the real source of the leak — then fixing that, not the symptom.

The hardest part of fixing a leaking roof is rarely the repair itself — it's finding where the water is actually getting in. Rain that enters at a cracked flashing can run a metre or more along the underfelt and rafters before it drips, so the stain on your ceiling is a clue, not an answer. Repairs made at the stain fail; repairs made at the source last.

We work through the likely entry points in order of probability for your roof type: flashings and chimney junctions first (the most common culprits), then valleys and ridges, then the tiles or slates themselves, then less obvious routes like cracked mortar verges and failed underfelt. Where a leak only appears in certain wind directions, that narrows the search further — wind-driven rain uses routes vertical rain never finds.

Once found, most leaks are modest repairs: a re-dressed flashing, a handful of replaced tiles, a re-lined valley section. We photograph what we find and what we fix, so you can see the fault without going up a ladder.

Repair options

Repair or replace

A leak on an otherwise sound roof is almost always worth repairing. The exceptions we'll be honest about: underfelt that has perished across the roof (each repair just moves the drip), coverings failing in multiple places at once, and roofs where this is the third or fourth leak in as many years. In those cases we'll price the repair and set out the replacement arithmetic alongside it — your call, made with real numbers.

Our process

How we do it

Send photographs of the ceiling damage and, if you can safely take one, the roof from outside. We inspect, locate the entry point, and quote for the specific repair. If water is coming in now, say so — we prioritise live leaks and can make the area weathertight ahead of the full repair.

Common questions

Frequently asked

The leak only happens in heavy or windy rain — why? +

Because the entry route needs volume or wind to operate: water backing up a blocked valley, or wind pushing rain up under tile laps and past worn flashings. These intermittent leaks are the ones most often misdiagnosed — the wind direction and rain type when it happens are genuinely useful clues, so note them down.

Can you stop the leak today? +

Usually we can make it weathertight the same day — sheeting, temporary flashing or first-aid to the fault — with the permanent repair following once the roof is dry and materials are matched. A live leak into the house is treated as urgent.

Will my ceiling need repairing too? +

That depends how long the water has been coming in. Plasterboard that has been soaked once and dried usually just needs a stain block and repaint; board that has sagged needs replacing. We'll give you a straight assessment — the roof must be fixed first either way, or any ceiling repair is wasted.
