Electronic leak detection in Sibley's Green
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. Typical surveys look at a flat roof leak that can’t be traced and leaks through a covered membrane, on flat roof membranes, roof terraces and balconies and commercial flat roofs.
In a small place like Sibley's Green, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Electronic leak detection around Sibley's Green
Historic houses such as Horham Hall, about 1.9 miles west, show how far back building in the area around Sibley's Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, with post-war and more recent estates making up much of the newer housing. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Landlords with a home close to Stansted Airport station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings such as Putteridge High School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

How it works
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a small place like Sibley's Green, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Agree roof access with the managing agent if it’s shared
- Check the loft hatch can be reached
- Have keys ready for side gates, garages or roof access doors

Advice
What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks from walls, copings or rooflights
- The extent of water in the insulation
- Roofs whose membrane or build-up isn’t suitable

Common questions in Sibley's Green
Will you come out to Sibley's Green?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Is my home in Sibley's Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
What happens next?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Does ELD work under paving or planting?
On some roofs, yes. Covered roofs limit the methods we can use so we look at the roof first.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Do you climb onto every roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. Anything we cannot see is noted in the report.
Before and after the survey
Over many surveys, some simple habits stand out:
- Get leaks traced quickly
- Test new membranes before covering them
- Don’t keep patching the same spot
- Keep a note of leaks after rain
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
What happens if roof problems are left?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. Older and listed buildings around Sibley's Green may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
To find out what your survey will cost, phone 07833 053749 or send us an email with the address and some details. We will confirm the figure before booking.

Should I look at the roof myself first?
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book.
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.
