Electronic Leak Detection in Lullingstone
Electronic leak detection to pinpoint holes in flat roof membranes in Lullingstone. We’ve completed more than 5,000 surveys across London and the South East.
- Failed seams and laps
- Holes left by work on the roof
- New membranes needing a check before handover
What you can safely check yourself
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
How electronic leak detection works in Lullingstone
Our ELD testing covers flat roofs in Lullingstone and the rest of London and South East England. A visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. Typical surveys look at leaking laps in the waterproofing and breaches hidden under paving or planting, on flat roof membranes, single-ply roofs and commercial flat roofs.
Some older homes in villages like Lullingstone are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later, such as when you want to compare after future work.

The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Lullingstone can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Have any questions written down, so nothing gets missed
- Keep pets in another room
- Point out any leaks or damp patches

Signs you need electronic leak detection in Lullingstone
Joints and laps in a membrane can fail over time. A gap that is hard to see can let water in long before anyone notices.
Common reasons to book include:
- Holes left by work on the roof
- Breaches hidden under paving or planting
- Patched roofs that still leak
- Holes around roof penetrations
Landlords with a home close to Eynsford station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- Whether the price includes VAT
- What the survey will not cover
- Which viewpoints they use to see the roof
- Do they have a CAA Flyer ID and Operator ID for drone work?
FAQs for Lullingstone
Do you cover smaller places like Lullingstone?
Yes, Lullingstone is covered. We work right across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Lullingstone?
Yes, Lullingstone is within the area we cover. We survey roofs across London and South East England. You can call 07833 053749 or email us with the address and a few details, and we’ll talk through which survey suits.
What if it rains on the day?
Light rain doesn’t normally stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we will arrange another day with you.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Does ELD work under paving or planting?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We’ll discuss it before we quote.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.

Tips from our surveys
Nothing here needs a ladder. Our suggestions:
- Keep foot traffic on flat roofs to a minimum
- Clear flat roof outlets regularly
- Act on new leaks promptly
- Test new membranes before covering them
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Act on leaks quickly. Water under a membrane can spread.
What we cannot see
Without opening up the roof, some things stay hidden, so a survey has limits:
- Build-ups without a suitable layer below
- Fixing the holes we find
- Moisture spread under the membrane

What electronic leak detection looks like in Lullingstone
Lullingstone Castle, about 0.1 miles east, is one of the historic houses in the wider area around Lullingstone. 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 any change of roofing material on a listed home needs checking with the council first. Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you live in an older home near Church of Saint Botolph, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
