Electronic leak detection in Seven Kings
Our ELD report shows where each breach was found with photos. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photos. We survey flat roof membranes, green roofs and single-ply roofs, and common reasons people get in touch are gaps at membrane joints and waterproofing to test before it’s covered.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Seven Kings, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Where we cannot see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

How it works
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit 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 Seven Kings we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Clear the way to the loft hatch
- If it is not your property yet, arrange access through the agent
- Tell us about any leaks, stains or damp patches you know of

Advice
What a survey costs
All our prices include VAT. The things that change the price are:
- House, block, shop or office
- How tall the building is and how easy the roof is to see
- Chimneys, valleys, parapets and other details
- Any need for thermal images or a drone flight
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
What helps most when you contact us:
- Where water is showing inside, if it is
- Whether there is a loft hatch, a shared roof or tricky access
- When you need the report by
- The type of building and roof, such as pitched or flat
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please do not climb up for a closer look. To get started, ring 07833 053749 or drop us an email.
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.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
What happens if roof problems are left?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. In Seven Kings, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Questions from Seven Kings
Is parking a problem for a survey in Seven Kings?
It depends on the street. If Seven Kings has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does a conservation area affect roof work in Seven Kings?
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.
Do you cover Seven Kings for electronic leak detection?
Yes. We carry out electronic leak detection in Seven Kings, and the service is the same as everywhere else we work.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Will you go up on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
How do I arrange electronic leak detection in Seven Kings?
It is easiest to ring 07833 053749 or email us. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run seven days a week.
Flat and commercial roofs around Seven Kings
There are several hotels within about a mile and a half of Seven Kings, and like offices and blocks, hotels frequently sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Seven Kings is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as The Brewery, a flat roof over a business is out of sight and out of mind until it leaks. If your home is one of the older ones in the streets near St John the Evangelist, flat-roofed rear additions and dormers added over the years are worth checking.

What this survey can’t tell you

- Water entering through details rather than the membrane
- Repairing the breaches (that is for your roofer)
- Some conductive membranes

Common roof problems in Seven Kings
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
People typically book a survey when they’ve noticed something like this:
- Leaks under green or ballasted roofs
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
- A flat roof leak that cannot be traced
Landlords with a home close to Seven Kings station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
