Electronic leak detection in Debden Green: 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. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. We survey liquid-applied waterproofing, flat roof membranes and commercial flat roofs, and common reasons people get in touch are breaches around outlets and penetrations and water coming in under a flat roof.
Some older homes in villages like Debden Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Why act early in Debden Green
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Around Debden Green, older homes often have old roof timbers, where water from a failed roof can cause rot if it is left.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Why book with us
- Drones and thermal imaging where applicable
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- An independent view of the roof
- Surveys seven days a week
Take a look at what a roof survey costs or two real surveys.
How the survey works
Where it’s 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. All in, the survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Around Debden Green, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- First, you tell us about the roof build-up and where water is showing.
- 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.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent

What affects the price in Debden Green
When we price a survey, we consider:
- Whether thermal imaging or a drone is needed
- House, block, shop or office
- The roof’s overall size
- The shape of the roof and its details
To find out what your survey will cost, ring 07833 053749 or use the contact form and tell us about the roof. The price is agreed before a date is set.
Booking your survey
We will typically ask about:
- What made you get in touch
- Any marks or damp showing indoors
- Dates you are working to, like exchange
- Pictures of the roof from a safe spot, if you have them
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or drop us an email.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
How the survey changes by roof type
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We will tell you if yours is not suitable.
Debden Green questions
Does a conservation area affect roof work in Debden Green?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover smaller places like Debden Green?
Yes. Debden Green is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Mention it when you get in touch and we will explain what’s needed.
Does ELD work under paving or planting?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
Electronic leak detection around Debden Green
In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.3 miles east lies Hill Hall, a reminder of how long the area around Debden Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Take an older house close to Parish Church of St Mary: the flat roofs on later extensions tend to wear out long before the main roof. Take a building like Davenant Foundation School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Chingford station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

Tips that help
A little preparation and a few simple habits help. Some pointers:
- Get leaks traced quickly
- Test new membranes before covering them
- Have roof specifications to hand
- Make sure trades protect the waterproofing
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
