My Roof Is Leaking — What Should I Do? A Step-by-Step Guide for UK Homeowners

A leaking roof is one of the most stressful things a homeowner can deal with — especially when it happens on a dark, wet evening with water dripping through the ceiling. The good news is that the immediate steps are straightforward, and with the right roofer, most leaks are fixable quickly.

This guide walks you through exactly what to do if your roof is leaking in the UK, from managing the damage right now to getting it properly repaired.

Step 1: Contain the Damage Immediately

Before you do anything else, limit the water damage inside your home.

• Place buckets or towels beneath the drip to catch falling water
• Move furniture, electronics, and valuables away from the affected area
• If a ceiling is bulging with water, carefully pierce it with a screwdriver in the centre — this releases the water in a controlled way rather than letting the ceiling collapse under the weight
• Turn off any nearby electrics at the fuse box if water is near light fittings or sockets — water and electricity are a dangerous combination

Do not attempt to go onto the roof yourself, particularly in wet or windy conditions. Falls from roofs are one of the leading causes of serious injury on domestic properties.

Step 2: Find Out Where the Leak Is Coming From

Once you've managed the immediate situation, try to identify where the water is entering. This helps you give useful information to the roofer and can prevent you from being quoted for unnecessary work.

Common sources of roof leaks in UK homes include:

• Slipped, cracked, or broken tiles or slates — especially after stormy weather
• Failed lead flashing around the chimney, skylights, or where the roof meets a wall
• A blocked or broken valley — the channel where two roof slopes meet
• A perished or torn underlay — the breathable membrane beneath the tiles
• Blocked gutters — causing water to back up under the eaves
• Poorly sealed roof windows or skylights — a common issue with VELUX-style windows

From inside, go into the loft if it's safe to do so. Look for water staining, damp patches, or daylight visible through the roof structure. The entry point you find inside may not be directly above the drip — water can travel along timbers before falling.

Step 3: Document the Damage

Before any repairs are carried out:

• Take photos of the leak, any ceiling or wall damage, and anything you can see in the loft
• Note the date and time the leak started — useful for insurance claims
• Keep records of any emergency measures you took

This documentation is important if you need to make a claim on your home insurance, or if there's any dispute with a contractor later.

Step 4: Check Your Home Insurance

Many standard UK home insurance policies will cover sudden and unexpected roof damage — for example, tiles blown off in a named storm. However, they typically do not cover:

• Gradual deterioration due to age or lack of maintenance
• Pre-existing damage that wasn't repaired when first noticed
• Flat roof repairs on policies that exclude flat roofs (read the small print)

Contact your insurer as soon as possible to find out if the repair is covered. If it is, they may have approved contractors. If it isn't, you'll need to arrange repairs yourself.

Step 5: Find a Reputable Roofer — Quickly

This is where many homeowners go wrong. A leaking roof creates urgency, and that urgency can lead to poor decisions. Rogue traders are well aware of this and often target homeowners after storms.

Never use a roofer who:

• Cold-calls at your door, particularly after a storm
• Refuses to provide a written quote
• Cannot show proof of public liability insurance
• Asks for the full payment in cash upfront
• Cannot provide any references or reviews

Do use a roofer who:

• Has verifiable online reviews from previous customers
• Provides a written, itemised quote before starting work
• Holds public liability insurance (minimum £1 million cover)
• Is a member of the NFRC (National Federation of Roofing Contractors) or holds TrustMark accreditation
• Is willing to explain what they found and why it's causing the leak

Step 6: Understand the Quote

A reputable roofer will inspect your roof (usually from both outside and inside the loft space) before providing a quote. Make sure the quote clearly states:

• The cause of the leak
• Exactly what work will be carried out
• What materials will be used
• Whether scaffolding is included or charged separately
• How long the work will take
• What warranty or guarantee is offered on the repair

Don't be afraid to ask questions. A good roofer will welcome them.

How Much Will a Roof Leak Repair Cost?

Temporary Emergency Fixes — What Works and What Doesn't

If you cannot get a roofer out immediately (for example, at the weekend), there are some temporary measures that can help limit further water ingress:

• Roof repair tape or sealant — available from DIY stores, can provide a short-term fix on a flat roof or around a flashing join. Designed as temporary only.
• A tarpaulin — if you can safely access the area, a tarpaulin weighted and secured over the problem area can buy you time. Do not attempt this on a steep pitch or in poor weather.

These are stopgap measures only. They are not a substitute for a proper repair and should not be left in place for extended periods.

When Is a Repair Not Enough?

In some cases, a persistent leak is a sign of wider roof failure rather than an isolated problem. Signs that you may be facing a more significant issue include:

• Multiple leak points across different areas of the roof
• Significant sagging of the roof deck or timbers
• Widespread tile deterioration and moss/algae growth
• A roof that is more than 20–25 years old

In these situations, a full roof replacement may be the more economical long-term solution. Read our guide on new roof costs in the UK to understand what's involved.

Frequently Asked Questions

Is a leaking roof an emergency? Yes — a leaking roof should be treated as an urgent matter. Left unaddressed, even a small leak can cause significant damage to ceilings, timbers, insulation, and the internal fabric of your home. Most reputable roofers offer same-day or next-day call-outs for emergencies.

Can I claim on my home insurance for a leaking roof? You may be able to, depending on the cause and your policy. Sudden damage from a storm is often covered; wear and tear or lack of maintenance is typically excluded. Contact your insurer promptly after noticing the leak.

How long can I leave a leaking roof before it causes serious damage? Don't wait. Even a slow drip can saturate insulation, cause timber rot, and lead to mould growth within days, particularly in winter. The longer a leak is left, the more expensive the resulting damage is likely to be.

Will a roofer come out at the weekend for a leak? Many roofers offer emergency call-outs at weekends, though you may pay a premium. Use our directory to find emergency roofers available in your area today.
