Roof Leak? What to Do First, Who to Call, and What It Costs

First, the five minutes that matter

Before you phone anyone, do these four things. They take a couple of minutes and they are the difference between a stained ceiling and a replaced one.

1. Move what you can. Furniture, electronics, anything soft. Water spreads along joists and comes through in places you don't expect.
2. Catch the water. A bucket, a washing-up bowl, anything. Put a towel in the bottom — it stops the maddening drip noise and reduces splashing.
3. If the ceiling is bulging, pierce it. This feels wrong, but a bulge means water is pooling above the plasterboard. Push a screwdriver through the lowest point of the bulge and let it drain into a bucket. A controlled hole you can patch beats the whole ceiling coming down at three in the morning.
4. Kill the power if water is anywhere near electrics. Light fittings, downlights, sockets on the floor above. Turn off that circuit at the consumer unit and leave it off.

Take photographs before you tidy up

This is the step people skip and regret. Photograph the water coming in, the damage to the ceiling, the ruined carpet, everything — before you mop it or move it. If you end up claiming on buildings insurance, that evidence is worth real money, and "I cleaned it up straight away" is a genuinely difficult position to argue from.

Keep any damaged material too. A cracked slate that came off in a storm is evidence of storm damage; the same slate in a skip is nothing.

Where the leak actually is

Here is the thing that surprises most homeowners: the water on your ceiling is often nowhere near the hole in your roof. Water gets in at the weak point, then runs along the underside of the felt, down a rafter, across a ceiling joist, and drops through at the first gap it finds — which might be several metres away.

That's why "it's leaking above the back bedroom" isn't a diagnosis, and why poking about from a ladder rarely finds anything. The usual entry points are:

• Slipped or missing slates and tiles — the most common cause by a distance, especially after wind.
• Failed flashing — around chimneys, in valleys, and where a roof meets a wall. Lead work is where a lot of older Cumbrian roofs let go first.
• Blocked or broken guttering — water backing up over the fascia and in behind the roofline. Very common after a wet autumn.
• Perished felt — on a flat roof, or as the secondary barrier under a pitched roof. Once it's brittle it stops doing its job.
• Chimney flaunching and pointing — a stack that's lost its mortar will let water straight down the inside.

Is it actually an emergency?

Being honest about this saves you money. An active drip in wet weather is urgent — the damage compounds, and plasterboard, insulation and timber all suffer the longer it goes on. But it usually isn't a call-someone-out-at-midnight emergency.

The genuine emergencies are: water near electrics, a ceiling that's sagging, storm damage that's left the roof open to the weather, and anything structural. If that's what you're looking at, ring straight away — we cover emergency roof repairs across Carlisle and Cumbria seven days a week.

If it's a slow drip and the forecast is dry for a couple of days, you have time to get it looked at properly rather than paying premium for out-of-hours. A temporary patch in the rain often has to be redone anyway.

Who to call — and what to be wary of

Call a local roofer with a real address and a review history you can actually check. A leak is exactly the situation people get taken advantage of in, because you're stressed, the weather is bad, and you want it to stop.

Two warning signs worth knowing:

• Anyone who knocks on your door offering to fix it after a storm. Reputable roofers are too busy to cold-call streets.
• A quote for a full re-roof before anyone has properly inspected it. Plenty of leaks are a handful of slates and an afternoon's work.

What a roof leak repair costs

Cost depends almost entirely on what's causing it and how hard it is to reach. Replacing a few slipped slates on an accessible roof is a modest job. Re-leading a chimney flashing, with scaffolding, is a different scale entirely — and scaffolding for a typical Cumbrian home runs from around £500 to £2,000 before anyone touches the roof.

Our call-out is £90 within 10 miles of Carlisle city centre, and that includes a full inspection and a written quote — so you know what you're dealing with before you commit to anything. No call-out surprises.

If the inspection points towards replacement rather than repair, our roof cost calculator will give you a ballpark from your property type, covering and roof area before you go any further.

Will insurance pay for it?

Sometimes. Buildings insurance generally covers sudden damage — a storm rips slates off, a branch comes through. It generally does not cover gradual wear, or damage that follows from a lack of maintenance, which is how most slow leaks are classified.

Report it promptly, send the photographs, and get a written report from the roofer describing the cause. "Storm damage on the night of the 14th" is a claim; "the flashing has been perished for years" is not.

Stopping the next one

Most leaks we attend were visible from the ground months earlier. Clear your gutters twice a year, look up at the roofline after every serious blow, and get anything suspicious checked while it's still small. If you can't see the roof properly — and on most houses you can't — a drone survey covers the whole thing in an hour without scaffolding.
