Electronic Leak Detection in Highbury
We take a careful look at the flat roof membrane at your property in Highbury, and put it all in a written report with photos.
- Leaks through a flat roof with no obvious cause
- Repairs that haven’t stopped the leak
- Holes left by work on the roof
Different roofs, different checks
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We’ll tell you if yours isn’t suitable.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Electronic leak detection in Highbury: what you get
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. If testing is not possible, we’ll say so. We survey green roofs, liquid-applied waterproofing and single-ply roofs, and people most often book us about leaking laps in the waterproofing and stains far from any visible defect.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Highbury, 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.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Get leaks traced quickly
- Share any drawings of the roof
- Don’t let outlets block
- Check trades protect the waterproofing
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Do not leave a flat roof leak running. Water under a membrane can spread.
When to book a survey in Highbury
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Here are some of the things we see often:
- Damage from equipment installers
- New membranes needing a check before handover
- Leaks showing away from the breach
- Failed seams and laps
If you look after a shop, office or commercial unit, for instance near Hackney Walk, flat roofs over shops and units are easy to forget until water comes through a ceiling.
What to check before booking
- What experience they bring
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the price includes VAT
- Will the report include photos?
Local flat roofs in Highbury
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. There are several hotels within about a mile and a half of Highbury. If you look after one, a leak through a flat roof can put a room out of use.
A roof leak in a hotel or guest house around Highbury means lost rooms as well as repairs, so it pays to find faults before guests do. With Sutton House about 2 miles east, the area around Highbury has a long history. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

Questions from Highbury
Does a conservation area affect roof work in Highbury?
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.
Can parking be tricky for a visit in Highbury?
Normally it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability.
Is Highbury in your area?
Yes. We cover Highbury and the rest of Greater London, as part of our work across London and South East England. To book, call 07833 053749 or use the contact form.
What happens after the survey?
You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Why get it checked now?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.
Why book us in Highbury
- Weekday and weekend surveys
- Photographs and a written report every time
- PI and public liability insurance
- Independent findings on the roof’s condition
How the survey works
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit normally takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Leave side gates unlocked
- Keep pets out of the way during the survey
Getting a price
Photos help, if you have them. Take them safely from the ground or a window, and please do not climb up for a closer look. To get started, phone 07833 053749 or email us.
