What electronic leak detection looks like in Belgravia
Within a mile and a half or so of Belgravia there are several hotels, 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. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Apsley House lies about 0.4 miles north, so building around Belgravia goes back a long way. Older houses nearby often have flat roofs added much later, built to very different standards from the main roof. If you live in an older home near St Peter's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Landlords with a home close to London Victoria station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Belgravia is about 1 mile south of City of Westminster, in Greater London. Bookings from Belgravia are handled just like any other: a call or an email, a price, then a date. Belgravia is one of the places in Greater London where we work for electronic leak detection.

Electronic leak detection in Belgravia
We carry out electronic leak detection on flat roofs in Belgravia and across London and South East England. Testing typically takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Every roof is quoted on its size and build-up. You get a written report with photos. Typical surveys look at leaks through a flat roof with no obvious cause and leaks showing away from the breach, on commercial flat roofs, roof terraces and balconies and flat roof membranes.
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 Belgravia shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
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, whichever applies.

Checking the roof from ground level
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Common questions in Belgravia
Can you look at the flat roof of a hotel or office near Belgravia?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building.
Is parking a problem for a survey in Belgravia?
Typically it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Is Belgravia in your area?
Yes. We survey roofs in Belgravia and the rest of Greater London. To book, call 07833 053749 or drop us an email.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or use the contact form.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. From the street, a London terrace typically shows only its front slope or parapet, so in Belgravia we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- 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 method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Leave side gates unlocked
- Make sure the loft hatch can be reached
- Let us know about parking near the property

Why act early in Belgravia
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
