About our electronic leak detection in Westcombe Park
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. We will tell you if the roof can’t be tested. If you’re worried about leaks under green or ballasted roofs and new membranes needing a check before handover, a survey will tell you what’s going on, on commercial flat roofs, single-ply roofs and liquid-applied waterproofing alike.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Westcombe Park, the flat roof is frequently a shared part of the building.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Flat roofs in Westcombe Park
Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Westcombe Park 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 is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. There are several hotels within about a mile and a half of Westcombe Park, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Hotels and guest houses near Westcombe Park can’t easily close rooms for a leak, so it pays to find faults before guests do. For landlords with property near Westcombe Park station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Roof by roof
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll say if the test will not work.
Signs you need electronic leak detection in Westcombe Park
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see frequently:
- Leaks under green or ballasted roofs
- Gaps at membrane joints

- A flat roof leak that can’t be traced

What affects the cost of electronic leak detection
A few things affect what a survey costs:
- The roof’s overall size
- Height and safe access
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
To find out what your survey will cost, phone 07833 053749 or send us an email with the address and some details. We will confirm the figure before booking.
Getting in touch
There is no need for technical words. It’s enough to let us know:
- Where water is showing inside, if it is
- Photos of the roof, taken safely from the ground or a window
- Access details, such as a loft hatch or a shared roof
- Why you want a survey: buying, a leak, a storm or new work

Your questions about electronic leak detection in Westcombe Park
Is my home in Westcombe Park listed or in a conservation area?
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 Westcombe Park?
It can be, so it helps to let us know about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
How long does electronic leak detection take?
It normally takes more time on a big roof than a small one, with the construction of the roof playing a part too.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
How it works
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In Westcombe Park, as in much of London, lots of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- First, you tell us about the roof build-up and where water is showing.
- 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.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Clear the way to the loft hatch
- Keep pets in another room
Booking a survey

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
