What to Do If Your Roof Is Leaking: East London Emergency Guide

A roof leak is stressful. Water coming through your ceiling feels urgent and chaotic. But the steps you take in the first hour make a huge difference to how much damage occurs and how smoothly your insurance claim goes. This guide is written by East London roofers who handle emergency leaks every week across Hackney, Stratford, Bow, Barking, and all surrounding areas.

Step 1: Contain the Water (First 10 Minutes)

Place buckets, bowls, or any container under the drip point. If water is pooling on the ceiling and the plaster is bulging downward, place a large container beneath and carefully puncture the lowest point of the bulge with a screwdriver. This releases the water in a controlled stream rather than waiting for the ceiling to collapse and dump litres of water across the room.

Move furniture, electronics, rugs, and anything of value away from the affected area. If you cannot move heavy items, cover them with plastic sheeting, bin bags, or even shower curtains.

Step 2: Protect Electrics

If water is near light fittings, switches, or sockets, turn off the power to the affected circuit at your consumer unit (fuse board). Water and electricity are a lethal combination. Do not touch wet electrical fittings. If you are unsure which circuit to isolate, turn off the main switch until a professional can assess.

Step 3: Do NOT Go on the Roof

Every year, East London A&E departments treat people who have fallen from roofs while attempting emergency repairs. Wet roofs are dangerously slippery. Wind makes ladders unstable. You do not have the equipment, training, or insurance to work at height safely. Call a professional.

Step 4: Photograph Everything

Before cleaning up, take photographs and video of the water ingress point on the ceiling, any visible external damage from ground level, water damage to walls, floors, and furnishings, and the containers catching water. Your phone timestamps these automatically. This documentation is essential for insurance claims — insurers can and do reduce payouts when damage is not properly documented at the time of the event.

Step 5: Call a Roofer for Emergency Make-Safe

A professional emergency roofer will arrive within 1–2 hours across East London, identify the source of the leak, and make your roof watertight using tarps, temporary patches, or emergency fixings. Make-safe costs £180–£400 in East London. The permanent repair is quoted separately once conditions allow safe, quality work.

Be wary of rogue traders who appear after storms offering cheap fixes. Use an NFRC-registered roofer with verified reviews and public liability insurance.

Step 6: Contact Your Insurance Company

Report the leak to your buildings insurance provider within 24–48 hours. Provide the photographs, the roofer’s emergency assessment, and a description of when the leak started. Your insurer will either accept your roofer’s repair quote or send their own loss adjuster.

Buildings insurance covers sudden events (storm damage, impact, burst pipes) but not gradual deterioration or maintenance failures. If your roof was already in poor condition, the insurer may argue the leak was inevitable and reduce the claim.

Common Leak Sources in East London

Slipped slates (Hackney, Bow, Bethnal Green): Nail sickness on Victorian terraces causes slates to slip, exposing the felt or battens beneath. Water tracks along battens and appears far from the actual entry point, making diagnosis without a roof inspection difficult.

Failed flashings (all areas): Lead flashings around chimneys, abutments, and dormer windows crack, lift, and separate as the building moves through thermal cycling. The leak typically appears as a damp patch on the chimney breast or where the roof meets a wall.

Flat roof failure (Barking, Dagenham, Stratford): Felt flat roofs on extensions and post-war blocks blister, split, and lose adhesion. Water pools on the failed membrane and finds any weakness in the upstand or outlet seal.

Valley leaks (Ilford, Romford, Walthamstow): Lead or mortar valleys between roof slopes corrode and crack. Valleys carry concentrated water flow, so a small failure causes a large leak.

Blocked gutters (all areas): Overflowing gutters saturate fascia boards and external walls. The water tracks through the wall and appears as internal damp, often misdiagnosed as a roof leak when the actual problem is at the gutter.

What Emergency Make-Safe Involves

Our emergency team carries tarps, temporary fixings, boarding, and patching materials on every van. Make-safe work stops the water ingress and protects your property until a permanent repair can be completed in proper conditions. We photograph everything before and during the make-safe for your insurance records.

The permanent repair is scheduled once weather conditions are safe for quality work and materials are sourced. We quote the permanent fix during the emergency visit so you know exactly what to expect.

The Association of British Insurers requires policyholders to take reasonable steps to mitigate damage when a loss occurs. Failure to contain a leak (placing buckets, moving possessions) can reduce the amount an insurer will pay. Source: ABI Domestic Claims Guide.
