Electronic leak detection in Lanham Green
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. If you are worried about water coming in under a flat roof and leaks that return after repairs, a survey will tell you what’s going on, whatever the roof.
Flat roofs on exposed homes in small places like Lanham Green take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report is written in plain words, so you do not need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

Useful tips for Lanham Green property owners
From years of surveys, a few habits stand out as worth the effort:
- Tell us about the membrane and build-up if you know it
- Stay off the flat roof unless needed
- Note where leaks show inside and when
- Don’t let outlets block
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
When you need someone else
It helps to know what a survey will not do before booking:
- Some conductive membranes
- Moisture spread under the membrane
- Parts of the roof covered by fixed equipment
If you are not sure which survey you need, ring 07833 053749 or drop us an email and we’ll give you a straight answer before you book. What a survey covers and does not.

Do you need electronic leak detection in Lanham Green?
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
Things that often lead to a survey include:
- Leaks showing away from the breach
- Punctures from foot traffic or tools
- Leaking laps in the waterproofing
- Leaks that return after repairs
If you look after a building such as Cressing Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Lanham Green: your questions answered
Do you cover Lanham Green?
Yes. We cover the whole of London and South East England, and Lanham Green is part of that. You can ring 07833 053749 or send us an email with the address and a few details.
How do I find out if my home in Lanham Green is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll check whether ELD will work.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
What do I do with the report?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
What we do, step by step
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. A typical survey takes a time that depends on the roof’s area and construction, which we set out in the quote. For a village or hamlet like Lanham Green, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can be seen safely, inside and out.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Show us where any leaks or stains appear
- Buyers: confirm access with the estate agent or seller
- Jot down any questions you want answered
Getting a price
Booking is simple: just phone 07833 053749 or use the contact form and give us some details about the property and we will suggest the right survey. We confirm the price before anything is booked.

What electronic leak detection looks like in Lanham Green
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there.
For landlords with property near Cressing station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take an older house close to Parish Church of All Saints: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
