How electronic leak detection works in White City
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It is testing only, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey single-ply roofs, liquid-applied waterproofing and green roofs, and people most often book us about water coming in under a flat roof and stains far from any visible defect.
On a London roof terrace or a flat roof over a back addition, water often 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 White City, the roof above may belong to the building rather than one flat.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Tips that help
These tips come from what we see on roofs every week:
- Consider ELD before paving or planting goes on
- Limit access to the roof
- Avoid repeated repairs without finding the cause
- Act on new leaks promptly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In a London area like White City, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- 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 the survey
- Let us know about parking near the property
- Have any paperwork from past roof work to hand
- Keep pets in another room

Checking the roof from the ground
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
Leave it or get it looked at?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. Any roof job in White City means planning around parking, neighbours and access. That is a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

Do you need electronic leak detection in White City?
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
We are often asked to look at:
- Breaches around outlets and penetrations
- Failed seams and laps
- Leaks showing away from the breach
- Holes left by work on the roof
For an older house near a landmark such as St Michael and St George, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- Is there a chance to talk the report through?
- Their track record with similar roofs
- Which parts of the roof they’ll actually see
- How soon the report will arrive
Electronic leak detection in White City: local notes
White City has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as Westfield London, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you run a hotel or guest house in or near White City, a roof problem can mean rooms out of use, so it pays to find faults before guests do.

FAQs for White City
Is parking a problem for a survey in White City?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
How do I find out if my home in White City is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
What do I do with the report?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Do you need to get into the loft?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That’s how we locate breaches you cannot see.
How quickly is the report sent?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
