How electronic leak detection works in Brompton
ELD suits many waterproofing membranes on flat roofs 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. Tell us about your roof to find out more. We survey single-ply roofs, flat roof membranes and green roofs, and people most frequently book us about leaks through a flat roof with no obvious cause and gaps at membrane joints.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Brompton, the roof above may belong to the building rather than one flat.
Where we can’t see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Why get it checked now?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

Flat and commercial roofs around Brompton
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Within a mile and a half or so of Brompton there are several hotels. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Shop and office owners around Harrods may find that a flat roof over a business is out of sight and out of mind until it leaks. Anyone responsible for a site like Hellenic College of London will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Questions from Brompton
How do I find out if my home in Brompton is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Can parking be tricky for a visit in Brompton?
Typically it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
How do I book a survey in Brompton?
Just ring 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when booking.
How do you choose the testing method?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
What happens on the day
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. The visit normally takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Many London properties are flats or terraces with no 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 you book.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
How to prepare
- Make sure pets are kept safely away
- For flats, make sure roof access has been agreed
- Check the loft hatch can be reached

Advice
When to book a survey in Brompton
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Common reasons to book include:
- Holes left by work on the roof
- Water coming in under a flat roof
- Holes around roof penetrations
- New membranes needing a check before handover
Historic houses such as Carlyle's House, about 0.8 miles south, show how far back building around Brompton goes. Older houses nearby often have flat roofs added much later, built to very different standards from the main roof.
Before booking anyone
- Whether they hold professional indemnity and public liability insurance
- Whether VAT is added on top
- Whether the inside of the roof is included
- How long they’ve been surveying roofs
How we price electronic leak detection
A few things affect what a survey costs:
- The number of roofs, including extensions and garages
- Building height and the viewpoints available
- If the survey needs thermal imaging or a drone
- House, block, shop or office
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before booking.
Helping us price your survey
What helps most when you contact us:
- Anything about access we should know
- Pictures of the roof from a safe spot, if you have them
