Electronic Leak Detection in Canning Town
Not sure what state the flat roof membrane is in? You can book electronic leak detection in Canning Town and across Greater London.
- Leaks showing away from the breach
- Waterproofing to test before it is covered
- Patched roofs that still leak
How it works
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Surveys in Canning Town can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it’s useful to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Tell us about any leaks, stains or damp patches you know of
- Mention any parking restrictions on your street
- Dig out any old roof reports or invoices
Booking a survey
We confirm the price for the job before booking, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, call 07833 053749 or use the contact form.

About our electronic leak detection in Canning Town
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. If you’re worried about breaches around outlets and penetrations and leaks under green or ballasted roofs, a survey will tell you what’s going on, on green roofs, single-ply roofs and commercial flat roofs alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Canning Town, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Why act early in Canning Town
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. In Canning Town, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.

Before and after the survey
Over many surveys, some simple habits stand out:
- Avoid repeated repairs without finding the cause
- Have roof specifications to hand
- Test new membranes before covering them
- Act on new leaks promptly
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Electronic leak detection in Canning Town: local notes
Canning Town has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Many homes in inner London are Victorian and Edwardian terraces, often with 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. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If your house is among the older ones in the streets near St Cedd's Church, the flat roofs on later extensions tend to wear out long before the main roof. Shop and office owners around Stratford Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.

Common roof problems in Canning Town
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Most people get in touch when they’ve noticed something like this:
- Failed seams and laps
- Water coming in under a flat roof
- Damage from equipment installers
- Stains far from any visible defect
For site and facilities teams at buildings like Rosetta Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Canning Town questions
How do I find out if my home in Canning Town is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you cover commercial flat roofs around Canning Town?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
How much time does ELD need?
Testing typically takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Let us know about it as you book and we’ll explain what’s needed.
