Trotton Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Trotton. We have completed more than 5,000 surveys across London and South East England.
- A flat roof leak that cannot be traced
- Patched roofs that still leak
- Leaks through a covered membrane
How electronic leak detection works in Trotton
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. We’ll say if your roof does not suit either method before any testing starts. We are often asked to look into breaches around outlets and penetrations and leaks showing away from the breach, on liquid-applied waterproofing, flat roof membranes and green roofs.
Somewhere as small as Trotton, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Electronic leak detection around Trotton
A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Cowdray House, about 3.2 miles east, show how far back building in the area around Trotton goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Anyone responsible for a site like Stedham Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Trotton is about 6 miles east of Petersfield, in Hampshire. Trotton gets the same service as everywhere else we work: a careful inspection, photos and a written report. Trotton is one of the places in Hampshire we cover for electronic leak detection. Our Portsmouth page covers surveys nearby.
Every address in GU31 is within our area for electronic leak detection, from the main roads to the quietest streets. Neighbouring places we cover for electronic leak detection include Dumpford (1 mile south-west), Elsted Marsh (1 mile south), Ingrams Green (1 mile south), Elsted (2 miles south-west) and Didling (2 miles south). Within a short drive, we also cover Havant (12 miles south-west), Horndean (11 miles south-west), Alton (13 miles north-west), Waterlooville (13 miles south-west), Petersfield (6 miles west) and Purbrook (13 miles south-west).
Local landmarks in Trotton
We work in homes and buildings around The Keeper's Arms Public House. A little further out are Midhurst Community Hospital (3 miles east) and Midhurst Museum (2.9 miles east). Open spaces near Trotton include Iping and Stedham Commons and Wheeler's Down.
Signs you need electronic leak detection in Trotton
Holes in a membrane often come from feet, tools or debris. Many are tiny but water still finds them.
Signs worth acting on include:
- Repairs that haven’t stopped the leak
- Leaks under green or ballasted roofs
- Holes left by work on the roof
- Leaks showing away from the breach
Take an older house close to St George's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Choosing a roof surveyor
- How much experience they have with roofs like yours
- Whether you get a written report with photos
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What’s outside the scope of the survey
The survey, step by step
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey normally takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. For a village or hamlet like Trotton, the journey is planned beforehand: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Have any questions written down, so nothing gets missed
- Leave side gates unlocked
- Tell us about any leaks, stains or damp patches you know of

Related advice
Trotton: your questions answered
How do I find out if my home in Trotton is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Do you cover smaller places like Trotton?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
What is electronic leak detection?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That’s how we locate breaches you can’t see.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What does the report include?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Will you walk on the roof?
Only where it’s safe to do so. We inspect what can safely be seen: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
What electronic leak detection doesn’t cover
Before booking, it’s worth knowing what a survey won’t do:
- Fixing the holes we find
- The extent of water in the insulation
- Sections we can’t safely access
If you are not sure which survey you need, phone 07833 053749 or email us and we’ll give you a straight answer before you book. What a survey covers and does not.
Roof types and parts we check
- Flat roof membranes
- Single-ply roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Green roofs
- Commercial flat roofs
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check trades protect the waterproofing
- Have roof specifications to hand
- Note where leaks show inside and when
- Act on new leaks promptly
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.
Different roofs, different checks
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant, which helps when budgeting.
Freeholders and residents’ companies use a roof report to plan and budget.
