Electronic leak detection in Hadley Wood: what you get
We carry out electronic leak detection on flat roofs in Hadley Wood and across London and South East England. A visit usually takes a length of time set by the roof’s area and construction, which we set out in the quote. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you’ve noticed stains far from any visible defect and leaks under green or ballasted roofs, we can find out what’s behind it, whatever the roof.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Hadley Wood, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What we do, step by step
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof cannot be seen, the report says so. The survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In Hadley Wood, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- 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
- Let us know about parking before the day
- Have keys ready for side gates, garages or roof access doors
- Clear the way to the loft hatch
Arrange a survey
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or send us an email.
Advice
Flat roofs in Hadley Wood
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 2.6 miles north lies Wyllyotts Manor, a reminder of how long the area around Hadley Wood has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Hadley Wood station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark such as St Paul's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Hadley Wood is about 1 mile north-east of Barnet, in Greater London. If you’re in Hadley Wood, booking works exactly as it does anywhere else: a call or an email, a price, then a date. We cover towns and villages across Greater London, large and small. There’s also a page for London.

Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Limit access to the roof
- Don’t leave water getting in
- Keep outlets clear of debris
- Note where leaks show inside and when
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.

Hadley Wood: your questions answered
Will parking be an issue for a roof survey in Hadley Wood?
Usually 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 find out if my home in Hadley Wood is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How do I book a survey in Hadley Wood?
To arrange a survey, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Do you cover Hadley Wood for electronic leak detection?
Yes. We carry out electronic leak detection in Hadley Wood.
How is ELD priced?
We quote for each roof individually. Let us know about the roof and where it leaks. Just ring 07833 053749 or use the contact form for a quote.
Can you survey in bad weather?
Light rain doesn’t usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather is not suitable.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Common roof problems in Hadley Wood
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Typical things we’re asked to look at include:
- Punctures from foot traffic or tools
- Leaks under green or ballasted roofs
- Leaks that return after repairs
- Gaps at membrane joints
For a London address like Hadley Wood, it helps to know about controlled parking before the day, along with any off-street space.
What to check before booking
- Is there a chance to talk the report through?
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- Which limits apply to the survey
