Electronic Leak Detection in Dagenham
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Dagenham and across Greater London, with plain-English findings.
- Leaks through a covered membrane
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
How it works
Once we have finished looking, we write up our findings in a report with photographs, emailed to you. As for time on site, most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. For a visit in Dagenham, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Keep pets inside or away from the areas we are looking at
- Let us know about parking before the day
- Make a note of anything you’d like us to look at
Getting a price
If you have photos of the roof, send them over. Pictures from the ground or a window are fine; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.

About our electronic leak detection in Dagenham
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. We survey green roofs, flat roof membranes and roof terraces and balconies, and people most often book us about repairs that haven’t stopped the leak and leaks showing away from the breach.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Dagenham shapes how it is checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
The report is written in plain words, so you do not need to be a roofer to follow it. Photographs show what each point refers to, and recommendations are put with the most urgent first where relevant.

Do you need electronic leak detection in Dagenham?
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
It is worth booking a survey if you’ve seen:
- Breaches around outlets and penetrations
- Repairs that haven’t stopped the leak
- Punctures from foot traffic or tools
- New roofs to check before paving or planting
If you run a business near The Brewery, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Before booking anyone
- Whether the inside of the roof is included
- Whether they hold professional indemnity and public liability insurance
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Is VAT included in the price?

Prices for electronic leak detection in Dagenham
What a survey costs depends on the time and equipment it needs. The main factors are:

- Any need for thermal images or a drone flight
- The size of the roof
- Extensions, dormers and garages with roofs of their own
For a price for your roof in Dagenham, phone 07833 053749 or email us with the address and some details. We will confirm the figure before booking.

Common questions in Dagenham
Can parking be tricky for a visit in Dagenham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Does a conservation area affect roof work in Dagenham?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How quickly is the report sent?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Can every flat roof be tested?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof won’t work, we will say so at the start.
How much time does ELD need?
It usually takes more time on a big roof than a small one, with the construction of the roof playing a part too.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
Flat roofs in Dagenham
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Dagenham is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Rainham Hall, about 2 miles south-east, is one of the historic houses in the wider area around Dagenham. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings like Village Infants' School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to St. Peter and St. Paul: the joins between later flat roofs and the old walls are where problems typically start.
Dagenham is about 3 miles south of Romford, in Greater London. Whether the building in Dagenham is a house, a flat or a commercial unit, the roof can be surveyed. Our area takes in places right across Greater London, large and small. We also survey roofs in London.

When you need someone else
In fairness, there are limits to any roof survey:
- The extent of water in the insulation
- Sections we cannot safely access
- Build-ups without a suitable layer below
If in doubt, phone 07833 053749 or email us and we’ll suggest the right survey before you book. The full list of what we check.
Roofs we survey in Dagenham
- Green roofs
- Commercial flat roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Roof terraces and balconies
Before and after the survey
These tips come from what we see on roofs every week:
- Stay off the flat roof unless needed
- Avoid repeated repairs without finding the cause
- Keep a note of leaks after rain
- Tell us about the membrane and build-up if you know it
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.
