Electronic leak detection for homes and businesses in Ladywell
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We’ll tell you if the roof cannot be tested. Typical surveys look at new roofs to check before paving or planting and holes left by work on the roof, across liquid-applied waterproofing, single-ply roofs and roof terraces and balconies.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Ladywell shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

What electronic leak detection does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- How wet the insulation is
- Water entering through details rather than the membrane
- Repairing the breaches (that’s for your roofer)

Common questions in Ladywell
Is Ladywell in the area you cover?
Yes, Ladywell is within the area we cover. We survey roofs across London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Will parking be an issue for a roof survey in Ladywell?
It can be, so it helps to tell us about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
How do I arrange electronic leak detection in Ladywell?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
Can you inspect my roof with a drone?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
What we’re asked to look at in Ladywell
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Typical things we’re asked to look at include:
- Stains far from any visible defect
- New roofs to check before paving or planting
- Leaks through a flat roof with no obvious cause
- Gaps at membrane joints
Take an older house close to Church of St Mary the Virgin: flat-roofed rear additions and dormers added over the years are worth checking.
Before you book any roof surveyor
- Is VAT included in the price?
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- What they will not be able to tell you
- What follow-up you get after the report
Local flat roofs in Ladywell
With Queen's House about 2 miles north, Ladywell sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Ladywell is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Ladywell is in London, so parking needs planning: let us know about parking bays, permits or a driveway as you book, as a space near the door cannot be promised. Anyone responsible for a site like St Mary's Lewisham Church of England Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking and it will help the survey.
Tips from our surveys
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Ask contractors to protect the membrane
- Don’t keep patching the same spot
- Tell us about the membrane and build-up if you know it
- Clear flat roof outlets regularly
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
Why it’s worth a survey now in Ladywell
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. 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: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

How the survey works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. For a visit in Ladywell, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Jot down any questions you want answered
- Mention any parking restrictions on your street
- Have keys ready for side gates, garages or roof access doors
Getting a price
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To send them or to book, call 07833 053749 or use the contact form.
