Electronic leak detection in Richmond upon Thames, Greater London
Wondering about the flat roof membrane at a property in Richmond upon Thames? We carry out electronic leak detection in Richmond upon Thames and across Greater London, with plain-English findings.
- Punctures from foot traffic or tools
- Leaks at pipes, outlets or fixings
- Leaks showing away from the breach
Electronic leak detection in Richmond upon Thames: what you get
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. We’re often asked to look into breaches around outlets and penetrations and leaks through a flat roof with no obvious cause, on flat roof membranes, commercial flat roofs and roof terraces and balconies.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Richmond upon Thames shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What we are asked to look at in Richmond upon Thames
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Typical things we are asked to look at include:
- New membranes needing a check before handover
- Leaks that return after repairs
- Failed seams and laps
- Leaks through a flat roof with no obvious cause
Pembroke Lodge, about 1.3 miles south, is one of the historic houses in the wider area around Richmond upon Thames. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Why get it checked now?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

- Professional indemnity and public liability insurance

The survey, step by step
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit normally takes as long as needed for the membrane area and the build-up, which we set out in the quote. In a London area like Richmond upon Thames, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work
- Mention any parking restrictions on your street
