Nine Elms Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Nine Elms and the rest of Greater London. We survey on weekdays and at weekends.
- Stains far from any visible defect
- Leaks that return after repairs
- Breaches hidden under paving or planting
Why it’s worth a survey now in Nine Elms
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection for homes and businesses in Nine Elms
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof can’t be tested. We survey commercial flat roofs, roof terraces and balconies and green roofs, and people most frequently book us about patched roofs that still leak and leaks through a flat roof with no obvious cause.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Nine Elms, the roof above may belong to the building rather than one flat.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Questions from Nine Elms
How do I find out if my home in Nine Elms is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is parking a problem for a survey in Nine Elms?
It can be, so it helps to let us know about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or send us an email.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put by urgency where it matters.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to.
What we cannot see
In fairness, a roof survey has limits:
- Repairing the breaches (that is for your roofer)
- Areas we cannot reach or that cannot be tested
- How wet the insulation is
If in doubt, phone 07833 053749 or drop us an email and we will recommend the right survey before you book. The full list of what we check.
What we check
- Roof terraces and balconies
- Single-ply roofs
- Green roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
Before and after the survey
There’s plenty you can do without going near the roof. What helps most:
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Share any drawings of the roof
- Keep outlets clear of debris
Questions about the results are welcome. We can talk you through the findings.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Nine Elms runs like any other.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Leave a clear route to the loft
- For a flat or shared roof, check access with the freeholder or managing agent
- Note where any stains or damp appear
Booking a survey
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or use the contact form.

When to book a survey in Nine Elms
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
A survey makes sense if you’ve noticed:
- A flat roof leak that can’t be traced
- Holes around roof penetrations
- Damp inside with no sign on the roof
- Leaking laps in the waterproofing
If you run a hotel or guest house in or near Nine Elms, a roof problem can mean rooms out of use.
Before booking anyone
- How they plan to inspect the roof safely
- Their insurance cover
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
Electronic leak detection around Nine Elms
There are several hotels within about a mile and a half of Nine Elms, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Nine Elms is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For businesses in and around places like Harrods, the flat roofs over shops and commercial units are worth checking before a leak, not after. Landlords with a home close to Battersea Park station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
