Electronic leak detection in East Barnet, Greater London
Electronic leak detection in East Barnet, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.

- Leaking laps in the waterproofing
What we look for on each type of roof
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Electronic leak detection in East Barnet: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. If you’ve noticed leaks that return after repairs and failed seams and laps, a survey will tell you what’s going on, on roof terraces and balconies, commercial flat roofs and liquid-applied waterproofing alike.
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 block or conversion in East Barnet, the flat roof is often a shared part of the building.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Prices for electronic leak detection in East Barnet
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- The number of roofs, including extensions and garages
- Roof area
- House, block, shop or office
- Height and safe access
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you get in touch
There’s no need for technical words. Just let us know:
- Photos of the roof, taken safely from the ground or a window
- What made you get in touch
- Where the property is, with the postcode
- The kind of building and roof involved
We confirm the price for your roof before you book, 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 email us.
Questions from East Barnet
Is parking a problem for a survey in East Barnet?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
How do I find out if my home in East Barnet is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Do you work in East Barnet?
Yes, we do. We carry out electronic leak detection in East Barnet, and the service is the same as everywhere else we work.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
How fast do I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, let us know as you book.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
What we can’t see
It’s useful to know what a survey will not do before you book:
- Leaks from walls, copings or rooflights

Electronic leak detection in East Barnet: local notes
The wider area around East Barnet has a long history of building, with Heath Hall about 4.2 miles south. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you own a rental within reach of Oakleigh Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For a London address like East Barnet, it helps to know about controlled parking before the day, along with any off-street space. For site and facilities teams at buildings such as Church Hill School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What happens on the day
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes a time that depends on the membrane area and the build-up, which we set out in the quote. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Let us know where we can park nearby

Checking the roof from ground level
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.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
