Electronic leak detection in Hackney Marshes: what you get
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It is testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. Common reasons to book are failed seams and laps and holes left by work on the roof, across liquid-applied waterproofing, flat roof membranes and green roofs.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Hackney Marshes, the flat roof is often a shared part of the building.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What we cannot see
Some things can’t be seen without opening up the roof, and that sets some limits:
- Repairing the breaches (that is for your roofer)
- Sections we cannot safely access
- Water entering through details rather than the membrane

- Liquid-applied waterproofing
- Flat roof membranes
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
- Single-ply roofs
Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.
What you get with us
- Independent findings on the roof’s condition
- Photographs and a written report every time
- Thermal imaging and drones used where they help
- Professional indemnity and public liability insurance

FAQs for Hackney Marshes
Will parking be an issue for a roof survey in Hackney Marshes?
Sometimes, yes. If Hackney Marshes has controlled parking where you are, a visitor permit is the easiest answer.
Do you cover commercial flat roofs around Hackney Marshes?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you will get a quote based on the building, and roof access is agreed with you before the visit.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you work in Hackney Marshes?
Yes. We cover Hackney Marshes and the rest of Greater London, as part of our work across London and South East England. To book, ring 07833 053749 or email us.
Do you look in the loft space?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or drop us an email for a quote.
Tips that help
Small things make a difference. Some pointers:
- Use boards when working on the roof
- Clear flat roof outlets regularly
- Consider ELD before paving or planting goes on
- Don’t keep patching the same spot
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

How the survey works
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely, from the ground, from windows, in the loft space and by drone where it applies. Most surveys take a time that depends on the membrane area and the build-up, which we’ll explain when we quote. In Hackney Marshes, as in much of London, lots of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Unlock side gates and any roof access doors
- Show us where any leaks or stains appear
- For a flat or shared roof, check access with the freeholder or managing agent
How to book
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or use the contact form.

Electronic leak detection in Hackney Marshes: local notes
There are several hotels within about a mile and a half of Hackney Marshes. If you look after one, a leak through a flat roof can put a room out of use. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For landlords with property near Lea Bridge station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For businesses in and around places like Hackney Walk, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- How many separate roofs there are, such as extensions, dormers and garages
- Height and safe access
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Do you need electronic leak detection in Hackney Marshes?
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in long before anyone notices.
A survey can pick up problems like:
- Stains far from any visible defect
- Breaches hidden under paving or planting
- New roofs to check before paving or planting
- Leaking laps in the waterproofing
For an older house near a landmark like The Risen Christ and All Souls, flat-roofed rear additions and dormers added over the years are worth checking.
Before you book any roof surveyor
- Their drone registration, if they fly one
- What they won’t be able to tell you
- Whether the roof space is looked at, where there is one
- Is there a chance to talk the report through?
