Electronic leak detection in Hadley, Greater London
Wondering about the flat roof membrane at a property in Hadley? We carry out electronic leak detection in Hadley and across Greater London.
- Damp inside with no sign on the roof
- Failed seams and laps
- Leaks through a covered membrane
What we look for on each type of roof
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We will tell you if yours isn’t suitable.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Electronic leak detection in Hadley: what you get
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 will use. We will say if your roof does not suit either method before any testing starts. Common reasons to book are holes around roof penetrations and water coming in under a flat roof, on green roofs, liquid-applied waterproofing and flat roof membranes.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Hadley, the flat roof is frequently a shared part of the building.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later.

What happens on the day
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. From the street, a London terrace typically shows only its front slope or parapet, so in Hadley we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
How to prepare
- Mention any parking restrictions on your street
- If the roof is shared, arrange access with whoever manages the building
- Clear the way to the loft hatch

Flat roofs in Hadley
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 2.8 miles north lies Wyllyotts Manor, a reminder of how long the area around Hadley has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings like Susi Earnshaw Theatre School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you own a rental within reach of New Barnet station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you run a business near Spires Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks.
Hadley is about 1 mile north-west of Barnet, in Greater London. Whether the building in Hadley is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Our Greater London coverage includes Hadley. We also survey roofs in London.

Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we’ll plan the visit with that in mind.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Your questions about electronic leak detection in Hadley
Can parking be tricky for a visit in Hadley?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Do you cover Hadley?
Yes, Hadley is one of the places we work. Every survey there gets the same written report with photos.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Will you check the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
What do I do with the report?
You’ll receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.

Leave it or get it looked at?
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In Hadley, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before you book.

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, which helps when we look at the roof.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
Prices for electronic leak detection in Hadley
When we price a survey, we consider:
- How complicated the roof is, with its valleys, chimneys and parapets
- Extra roofs, like extensions, dormers or garages
- Whether it’s a home or a commercial building
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
What we need to know
There’s no need for technical words. It’s enough to tell us:
- Your timetable, such as an exchange date
- Pictures from the garden or a window, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- The address and postcode of the property
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. For a price for your roof, ring 07833 053749 or send us an email.
