Electronic leak detection in Great Hallingbury: what you get
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you’ve noticed damp inside with no sign on the roof and damage from equipment installers, we can find out what’s behind it, on green roofs, single-ply roofs and flat roof membranes alike.
Some older homes in villages like Great Hallingbury 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 is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put by urgency where it matters.

Surveys for landlords and agents in Great Hallingbury
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, so they’re priced to suit.
Practical tips
From years of surveys, a few habits stand out as worth the effort:
- Keep foot traffic on flat roofs to a minimum
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Use boards when working on the roof
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Do not leave a flat roof leak running. Water under a membrane can spread.
The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Older rural homes like those around Great Hallingbury can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- You tell us about the roof and where water is showing.
- 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 the survey
- For a flat or shared roof, check access with whoever owns or manages the building
- If you’re buying, let the agent know when we are coming
- Leave a clear route to the loft

Common questions in Great Hallingbury
Is Great Hallingbury within the area you cover?
Yes. Great Hallingbury is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
How do I find out if my home in Great Hallingbury is listed?
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.
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, which shows us where the hole is.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will check whether ELD will work.
How much time does ELD need?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
Different roofs, different checks
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers but it depends on the layers.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. ELD can help locate them on suitable roofs.
Prices for electronic leak detection in Great Hallingbury
Not every roof costs the same to survey, for these reasons:
- How big the roof is
- Height and safe access
- Extensions, dormers and garages with roofs of their own
- Chimneys, valleys, parapets and other details
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you contact us
You don’t need to know any roofing terms. Just let us know:
- What made you get in touch
- The property’s address and postcode
- The style of property, from a terrace to a block
- Anything about access we should know
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you are ready.
Places near Great Hallingbury
What else we do in Great Hallingbury
Do you need electronic leak detection in Great Hallingbury?
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Look out for signs like these:
- Damage from equipment installers
- Leaks through a covered membrane
- New membranes needing a check before handover
- Patched roofs that still leak
If your home is one of the older ones in the streets near Church of St Giles, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before booking any roof surveyor
- Whether VAT is in the quoted price
- What the report includes, and whether it has photographs
- Whether the loft is part of the inspection
- Are they insured for the work?
