Barnehurst Electronic Leak Detection
We carry out electronic leak detection in Barnehurst and the rest of Greater London. We survey seven days a week.
- Breaches around outlets and penetrations
- Waterproofing to test before it is covered
- Punctures from foot traffic or tools
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photos as we go and record our findings for the written report. Most visits take a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In a London area like Barnehurst, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can be seen safely from the ground, windows, the loft and, where it’s safe, the roof itself.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Note where any stains or damp appear
- Jot down any questions you want answered
- Leave a clear route to the loft
Booking a survey
Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or send us an email.

How electronic leak detection works in Barnehurst
There are different ELD methods. Low-voltage methods typically need a wet roof surface and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. We’ll say if your roof does not suit either method before any testing starts. If you’ve noticed breaches hidden under paving or planting and punctures from foot traffic or tools, we can find out what’s behind it, whatever the roof.
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 Barnehurst, 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.

Questions from Barnehurst
Will parking be an issue for a roof survey in Barnehurst?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How do I find out if my home in Barnehurst is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We’ll tell you if yours isn’t suitable before testing.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Mention it when you contact us and we will explain what’s needed.

Checking the roof from ground level
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extra roofs, like extensions, dormers or garages
- The height of the building and how the roof can be seen safely
- How big the roof is
- Whether thermal imaging or a drone is needed
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What we need to know
What helps most when you contact us:
- Pictures from the garden or a window, if you have them
- What kind of property and roof it is
- Whether there is a loft hatch, a shared roof or tricky access
- Where any leaks, stains or damp patches show inside
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, phone 07833 053749 or email us.
Useful tips for Barnehurst property owners
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Make sure trades protect the waterproofing
- Keep outlets clear of debris
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
When to book a survey in Barnehurst
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
A survey makes sense if you’ve noticed:
- Failed seams and laps
- Punctures from foot traffic or tools
- New roofs to check before paving or planting
- Leaks through a flat roof with no obvious cause
Shop and office owners around Broadway Shopping Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.
Choosing a roof surveyor
- How soon the report will arrive
- What insurance they carry
- Whether VAT is in the quoted price
- What’s outside the scope of the survey
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. London’s older roofs frequently have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.
Why us?
- Independent findings on the roof’s condition
- Covered by professional indemnity and public liability insurance
- Visits on any day of the week
- Drones and thermal imaging where applicable

Local flat roofs in Barnehurst
About 1 mile south-west lies Hall Place and Gardens, a reminder of how long the area around Barnehurst has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Landlords with a home close to Barnehurst station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. Parking in Barnehurst, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
