Electronic Leak Detection in Lea Bridge
Electronic leak detection to pinpoint holes in flat roof membranes around Lea Bridge, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- New roofs to check before paving or planting
- Leaks through a flat roof with no obvious cause
- Patched roofs that still leak
How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely, from ground level, from windows, in the roof space and by drone where applicable. Most surveys take a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. From the street, a London terrace typically shows only its front slope or parapet, so in Lea Bridge we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Let us know about parking before the day
- Show us where any leaks or stains appear
- Keep pets out of the way during the survey

Advice
Electronic leak detection in Lea Bridge: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a report with photographs of each breach found. Typical surveys look at breaches hidden under paving or planting and breaches around outlets and penetrations, on single-ply roofs, green roofs and roof terraces and balconies.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Lea Bridge, the roof above may belong to the building rather than one flat.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later.

Roof by roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Do you need electronic leak detection in Lea Bridge?
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
People typically book a survey when they’ve noticed something like this:
- Leaking laps in the waterproofing
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
- A flat roof leak that can’t be traced
If you own a rental within reach of Clapton station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Choosing a roof surveyor

- How long the report takes to arrive
- How long they’ve been surveying roofs
- Whether you get a written report with photos
Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Have roof specifications to hand
- Record dates and spots where water appears
- Make sure trades protect the waterproofing
- Consider ELD before paving or planting goes on
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
FAQs for Lea Bridge
Does a conservation area affect roof work in Lea Bridge?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Can parking be tricky for a visit in Lea Bridge?
Parking in Lea Bridge, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can every flat roof be tested?
ELD doesn’t suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We’ll tell you if yours is not suitable at the start.
Do you cover Lea Bridge for electronic leak detection?
Yes. Lea Bridge is part of the area we cover, and the service is the same as everywhere else we work.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. In Lea Bridge, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Electronic leak detection around Lea Bridge
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Sutton House, about 1 mile south, show how far back building in the area around Lea Bridge goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof.
If you live in an older home near St Matthew, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you run a business near Hackney Walk, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
