About our electronic leak detection in Chawton
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. 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. We survey green roofs, roof terraces and balconies and commercial flat roofs, and people most frequently book us about damage from equipment installers and leaking laps in the waterproofing.
Older buildings in small places like Chawton may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Your questions about electronic leak detection in Chawton
Do you cover smaller places like Chawton?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Does a conservation area affect roof work in Chawton?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
How long does electronic leak detection take?
It normally takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting.
Are you structural engineers?
No. We are 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.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
What electronic leak detection looks like in Chawton
Within a mile and a half or so of Chawton there are several hotels, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Some Hampshire villages still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you look after a building such as Chawton Church of England Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. With Bentworth Hall about 2.8 miles west, the area around Chawton has a long history. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.

Tips that help
Most of what helps is simple and safe from the ground. Our suggestions:
- Act on new leaks promptly
- Keep outlets clear of debris
- Let us know about the membrane and build-up if you know it
- Consider ELD before paving or planting goes on
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
When to book a survey in Chawton
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
We are often asked to look at:
- Breaches around outlets and penetrations
- Leaks under green or ballasted roofs
- Leaks through a flat roof with no obvious cause
- Leaking laps in the waterproofing
For hotels and guest houses around Chawton, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.
Before booking any roof surveyor
- Their track record with similar roofs
- Whether any drone flown is registered with the CAA
- Whether the loft space is looked at, where there is one
- Which limits apply to the survey
Why it’s worth a survey now in Chawton
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Outbuildings and barns around Chawton are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has 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.

Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
How the survey works
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Chawton needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can safely be seen, inside and out.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Preparing for the visit
- Unlock side gates and any roof access doors
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller
