Victoria Electronic Leak Detection
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Victoria, with photographs and a clear written report.
- New roofs to check before paving or planting
- Leaking laps in the waterproofing
- Breaches hidden under paving or planting
Why act early in Victoria
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
To find out what your survey will cost, ring 07833 053749 or drop us an email with the address and some details. We’ll confirm the figure before booking.

Electronic leak detection in Victoria: what you get
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. We are often asked to look into leaks through a flat roof with no obvious cause and leaking laps in the waterproofing, on green roofs, liquid-applied waterproofing and flat roof membranes.
On a London roof terrace or a flat roof over a back addition, water often 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 Victoria, the flat roof is often a shared part of the building.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

What else we do in Victoria
What affects the price in Victoria
We confirm the price for your roof before booking. These are the things that affect it:
- The height of the building and how the roof can be seen safely
- The use of thermal imaging or a drone
- The size of the roof
- The number of roofs, including extensions and garages
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.
What we need to know
Some details help us suggest the right survey and price. When you contact us, tell us:
- Any stains, drips or damp patches you’ve seen indoors
- The property’s address and postcode
- Pictures from the garden or a window, if you have them
- What kind of property and roof it is
To arrange a survey, call 07833 053749 or email us and tell us the address and what’s prompted the survey. You’ll know the price before anything is booked.
Electronic leak detection in Victoria: local notes
Within a mile and a half or so of Victoria 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. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
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. If you run a business near Harrods, a flat roof over a business is out of sight and out of mind until it leaks. With Buckingham Palace about 0.4 miles north, the area around Victoria has a long history. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once.
Victoria is about 1 mile south of City of Westminster, in Greater London. Victoria gets the same service as everywhere else we work: a close look at everything that’s safely in view, photographs and a clear written report. Our area takes in places right across Greater London, from the larger towns to small villages.
Surveys in SW1V, SW1P and SW1X are booked the same way as anywhere else. We cover properties on Eaton Lane, Gerald Road and Wilton Road and the roads around them.

Questions from Victoria
Does a conservation area affect roof work in Victoria?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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 commercial flat roofs around Victoria?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
How do I book a survey in Victoria?
To book, call 07833 053749 or drop us an email and let us know the address and what you need to know. We will confirm the price and find a day that suits.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
How much time does ELD need?
Testing typically takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and anything out of sight is recorded in the report.
Do you work in Victoria?
Yes. Victoria is part of the area we cover, and the service is the same as everywhere else we work.
The survey, step by step
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Keep pets inside or away from the areas we are looking at
- Agree roof access with the managing agent if it is shared
- Buyers: confirm access with the estate agent or seller
Book a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
Advice
Honest limits
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- The extent of water in the insulation
- Carrying out the repair work
- Some conductive membranes

Roofs we survey in Victoria
- Liquid-applied waterproofing
- Green roofs
- Roof terraces and balconies
- Flat roof membranes
- Commercial flat roofs
- Single-ply roofs
Before and after the survey
A survey works best with a little help from you, before and after. Tips:
- Use boards when working on the roof
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
- Keep foot traffic on flat roofs to a minimum
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Don’t leave a flat roof leak running. Water under a membrane can spread.
