Electronic leak detection in Malden Rushett: what you get
Our ELD testing covers flat roofs in Malden Rushett and the rest of London and the South East. A visit normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a written report with photos. We survey green roofs, roof terraces and balconies and commercial flat roofs, and common reasons people get in touch are stains far from any visible defect and breaches hidden under paving or planting.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Malden Rushett, the roof above may belong to the building rather than one flat.
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, and what we’d suggest next.

What electronic leak detection doesn’t cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Parts of the roof covered by fixed equipment
- Fixing the holes we find
- Leaks from walls, copings or rooflights
Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we will tell you. What a survey covers and doesn’t.
What we check

- Liquid-applied waterproofing
- Green roofs

Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Record dates and spots where water appears
- Check new waterproofing before handover
- Have roof specifications to hand
- Stay off the flat roof unless needed
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Common roof problems in Malden Rushett
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey can pick up problems such as:
- New roofs to check before paving or planting
- Leaks under green or ballasted roofs
- Water coming in under a flat roof
- Leaks showing away from the breach
Parking in Malden Rushett, as in most of London, takes a little planning: tell us about permits, visitor bays or off-street space when you book.

Your questions about electronic leak detection in Malden Rushett
Is my home in Malden Rushett listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is parking a problem for a survey in Malden Rushett?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. That way the visit can be planned around it.
Do you look in the roof space?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Do you cover Malden Rushett for electronic leak detection?
Yes. Our area covers London and South East England, and that includes Malden Rushett.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Which days do you carry out surveys?
Surveys run on weekdays and at weekends. To arrange a date, phone 07833 053749 or use the contact form.
How we price electronic leak detection
All our prices include VAT. What changes the price is:
- Commercial roofs and larger buildings
- The use of thermal imaging or a drone
- How big the roof is
- Extra roofs, like extensions, dormers or garages
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 let us know when you contact us
The more you tell us, the easier it is to price the survey. When you contact us, it is useful to mention:
- Anything about access we should know
- Photos of the roof, taken safely from ground level or a window
- Your postcode, so we can check access and travel
- Any deadline, like an exchange date
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, call 07833 053749 or email us.
Should I look at the roof myself first?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
How it works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Malden Rushett runs like any other.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- For flats, make sure roof access has been agreed
- If you’re buying, check with the agent that we can get in
- Have any questions written down, so nothing gets missed

What electronic leak detection looks like in Malden Rushett
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.1 miles east lies Fitznells Manor, a reminder of how long the area around Malden Rushett has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Shop and office owners around The Ashley Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. Take a building like Chessington Community College: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
