South Kensington Electronic Leak Detection
Electronic leak detection in South Kensington and the rest of Greater London. We survey seven days a week.
- Leaks at pipes, outlets or fixings
- Repairs that haven’t stopped the leak
- Waterproofing to test before it is covered
Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Any roof job in South Kensington means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- More than 5,000 surveys completed

How electronic leak detection works in South Kensington
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work 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. We will tell you if the roof can’t be tested. If you’re worried about water coming in under a flat roof and breaches hidden under paving or planting, we can find out what’s behind it.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in South Kensington shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put by urgency where it matters.

Common questions in South Kensington
Does a conservation area affect roof work in South Kensington?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Will parking be an issue for a roof survey in South Kensington?
It depends on the street. If South Kensington has controlled parking where you are, a visitor permit is the easiest answer.
How long will testing take?
It normally takes a length of time set by the roof’s area and construction, which we’ll explain when we quote.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
How do you choose the testing method?
The roof decides the method. We’ll explain why when we quote.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
What you can safely check yourself
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
- Chimneys, valleys, parapets and other details
- The height of the building and how the roof can safely be seen
To find out what your survey will cost, call 07833 053749 or send us an email and let us know about the roof. We’ll confirm the figure before booking.
What to let us know when you contact us
A little information up front helps. Please include:
- Why you want a survey: buying, a leak, a storm or new work
- Your postcode, so we can check access and travel
- Your timetable, such as an exchange date
- Whether there’s a loft hatch, a shared roof or tricky access
Most bookings start with a short call: ring 07833 053749 or email us. You will have a price before anything is arranged.
Common roof problems in South Kensington
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Here are some of the things we see frequently:
- Leaking laps in the waterproofing
- Repairs that haven’t stopped the leak
- Punctures from foot traffic or tools
- Holes around roof penetrations
If you run a hotel or guest house in or near South Kensington, a roof problem can mean rooms out of use.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Are they insured for the work?
- Whether the inside of the roof is included
- How they’ll see the roof: from the ground, the loft, the roof or by drone

What else we do in South Kensington
How it works
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Surveys in South Kensington can be booked for any day of the week. 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 frequently give the best view of a rear addition.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Let us know about parking before the day
- If it is not your property yet, arrange access through the agent
- Leave a clear route to the loft
Book a survey
Getting a price is simple: just ring 07833 053749 or send us an email and give us a few details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
Advice
What electronic leak detection looks like in South Kensington
Within a mile and a half or so of South Kensington there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Carlyle's House lies about 0.6 miles south-east, so building around South Kensington goes back a long way. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. If yours is one of the older homes in the streets near Chapel of St Luke, the joins between later flat roofs and the old walls are where problems usually start.

Different roofs, different checks
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
