Electronic Leak Detection in Lambeth
Find out the condition of the flat roof membrane at your property in Lambeth from an independent roof surveyor. We visit on weekdays and at weekends.
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
- Failed seams and laps
What happens if roof problems are left?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Any roof job in Lambeth means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before you book.
Why book with us
- Covered by professional indemnity and public liability insurance

Electronic leak detection in Lambeth: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. Common reasons to book are repairs that haven’t stopped the leak and leaks through a flat roof with no obvious cause, across green roofs, liquid-applied waterproofing and commercial flat roofs.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Lambeth, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Electronic leak detection in Lambeth: local notes
Historic houses such as Benjamin Franklin House, about 1.2 miles north, show how far back building in the area around Lambeth goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. There are several hotels within about a mile and a half of Lambeth, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you own a rental within reach of Vauxhall station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Hotels and guest houses near Lambeth can’t easily close rooms for a leak, so it pays to find faults before guests do. For businesses in and around places such as Gabriel's Wharf, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Lambeth is about 1 mile south-west of London, in Greater London. Lambeth gets the same service as everywhere else we work: a proper look at whatever is safely visible, photographs and a clear written report. Our Greater London coverage includes Lambeth and the places around it.
All of SE11, SW1P and SW8 is within our area for electronic leak detection. You will find streets such as Gibson Road, Langley Lane and Randall Road. You’ll find Lambeth on the A3203 and A3204, so it is easy for us to get to. If you are just outside Lambeth, we cover Vauxhall (1 mile north), Kennington (1 mile south), Oval (1 mile south), Newington Butts (1 mile east) and St George's Fields (1 mile north-east). We also work in nearby towns such as Kensington (4 miles west), Shoreditch (3 miles north-east), Walthamstow (8 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles north-east) and Hampstead (5 miles north-west).
Local landmarks in Lambeth
Around Lambeth, our work takes us to homes and buildings near The Jolly Gardeners pub, Old Paradise Gardens and Lambeth Palace Library. Other local landmarks include Lambeth School of Art (under half a mile south) and Lilian Baylis Technology School (within half a mile south). Lambeth has its own railway station: Vauxhall station. Well-known places in the area include Newport Street Gallery (within half a mile north-east) and Evelina London Children's Hospital (0.5 miles north). The countryside around Lambeth includes Bellenden Road Nature Garden and Ludgate Hill.
What happens on the day
The visit typically starts outside and finishes in the loft: 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, with the construction of the roof playing a part too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Lambeth runs like any other.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Let us know where we can park nearby
- If you’re buying, let the agent know when we’re coming
- Jot down any questions you want answered

Related advice
Landlords, agents and block managers in Lambeth
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant beforehand.
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or email us with the addresses.
What you can safely check yourself
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. Do not go up yourself.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey.
Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Ask contractors to protect the membrane
- Find the breach before more patching
- Let us know about the membrane and build-up if you know it
- Record dates and spots where water appears
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Your questions about electronic leak detection in Lambeth
Will parking be an issue for a roof survey in Lambeth?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do you cover commercial flat roofs around Lambeth?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or drop us an email.
What’s the best way to book?
Simply ring 07833 053749 or send us an email with the address. We will ask a few questions, confirm the price and agree a date.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it as you book and we will explain what’s needed.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
