Electronic leak detection in Lambourne, Essex
Electronic leak detection to pinpoint holes in flat roof membranes in Lambourne. We’ve completed more than 5,000 surveys across London and South East England.
- Leaks under green or ballasted roofs
- Leaks at pipes, outlets or fixings

Electronic leak detection in Lambourne
There are different ELD methods. Low-voltage methods normally need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you before any testing starts. If you are worried about leaks under green or ballasted roofs and leaks that return after repairs, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Lambourne may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Tips from our surveys
These tips come from what we see on roofs every week:
- Find the breach before more patching
- Record dates and spots where water appears
- Check new waterproofing before handover
- Do not let outlets block
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.

What this survey can’t tell you
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- Fixing the holes we find
- Leaks from walls, copings or rooflights
- Parts of the roof covered by fixed equipment
If you are not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer before booking. The full list of what we check.
What we check
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
- Green roofs
What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
How we price electronic leak detection
Prices vary from roof to roof, and it comes down to:
- Roof area
- Any need for thermal images or a drone flight
- House, block, shop or office
- Features like valleys, chimneys, dormers and parapets
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.
What we need to know
We’ll normally ask about:
- Pictures from the garden or a window, if you have them
- Whether there’s a loft hatch, a shared roof or tricky access
- Your timetable, such as an exchange date
- Any marks or damp showing indoors
To arrange a survey, ring 07833 053749 or send us an email and tell us the address and what’s prompted the survey. You will know the price before anything is booked.
Lambourne questions
How do I find out if my home in Lambourne is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Is Lambourne within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. For a quote, call 07833 053749 or use the contact form.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to.
Landlord and commercial surveys in Lambourne
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or email us with the addresses.
How the survey works
It is useful 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. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Lambourne, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before we arrive
- Find any records of previous roof work
- Leave side gates unlocked
- If it isn’t your property yet, arrange access through the agent
Getting a price
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or use the contact form.
Advice
Local flat roofs in Lambourne
About 2.2 miles north lies Hill Hall, a reminder of how long the area around Lambourne has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you own one of the older houses in the streets near Parish Church of St Mary and All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a building such as Lambourne Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
