Little Chelsea Electronic Leak Detection
Find out the condition of the flat roof membrane at your property in Little Chelsea from an independent roof surveyor. Visits run on weekdays and weekends, in the daytime.
- Leaking laps in the waterproofing
- Waterproofing to test before it’s covered
- A flat roof leak that cannot be traced
Common roof problems in Little Chelsea
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Look out for signs like these:
- Holes left by work on the roof
- Failed seams and laps
- Patched roofs that still leak
- Breaches hidden under paving or planting
Shop and office owners around Harrods may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
What to check before booking
- How long they’ve been surveying roofs
- Whether the price includes VAT
- Their insurance cover
- Will the report include photos?
About our electronic leak detection in Little Chelsea
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. If you’ve noticed gaps at membrane joints and leaks under green or ballasted roofs, we can find out what’s behind it, on commercial flat roofs, liquid-applied waterproofing and single-ply roofs alike.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Little Chelsea, 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

Questions from Little Chelsea
Do you cover commercial flat roofs around Little Chelsea?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you ahead of the visit.
Will parking be an issue for a roof survey in Little Chelsea?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Will you fly a drone over my roof?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. For a quote, call 07833 053749 or email us.
Will you check the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Prices for electronic leak detection in Little Chelsea
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Height and safe access
- Whether it’s a home or a commercial building
- How many separate roofs there are, like extensions, dormers and garages
- Features like valleys, chimneys, dormers and parapets
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your survey before booking.
What we need to know
These details help when you contact us:
- Access details, like a loft hatch or a shared roof
- Where water is showing inside, if it is
- Photos of the roof, taken safely from ground level or a window
- Dates you’re working to, such as exchange
To arrange a survey, call 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will 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. For a visit in Little Chelsea, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at whatever is safely visible from ground level, windows, the loft and, where it is safe, the roof itself.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Jot down any questions you want answered
- Clear the way to the loft hatch
- Check pets are kept safely away

Advice
Roof by roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers, depending on the build-up.
Flat roofs in Little Chelsea
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Little Chelsea is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Little Chelsea has a number of hotels within about a mile and a half. If you look after one, a leak through a flat roof can put a room out of use.
Take an older house close to Church of St Andrew: the joins between later flat roofs and the old walls are where problems normally start. If you run a hotel or guest house in or near Little Chelsea, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition.
