Electronic leak detection in Dagenham Dock
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small 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 can repair them. You get a report with photos of each breach found. Common reasons to book are punctures from foot traffic or tools and leaks under green or ballasted roofs, on single-ply roofs, flat roof membranes and roof terraces and balconies.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Dagenham Dock shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put by urgency where it matters.

Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Flat roofs in Dagenham Dock
About 2.1 miles north-west lies Eastbury Manor House, a reminder of how long the area around Dagenham Dock has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Controlled parking zones are common in London, so mention any permit rules for Dagenham Dock. Shop and office owners around Gallions Reach Shopping Park may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.

Leave it or get it looked at?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.

Your questions about electronic leak detection in Dagenham Dock
Can parking be tricky for a visit in Dagenham Dock?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
How do I find out if my home in Dagenham Dock is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Before and after the survey
From years of surveys, a few habits stand out:
- Don’t let outlets block
- Get leaks traced quickly
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
What electronic leak detection does not cover
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- Fixing the holes we find
- How wet the insulation is
- Water entering through details rather than the membrane
If you are not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer before you book. What a survey covers and does not.

How it works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. In Dagenham Dock, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
How to prepare
- Make sure pets are kept safely away
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work
