How electronic leak detection works in Hounslow
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. Typical surveys look at punctures from foot traffic or tools and damp inside with no sign on the roof, across green roofs, commercial flat roofs and flat roof membranes.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Hounslow, the roof above may belong to the building rather than one flat.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, with the urgent items made clear.

Common questions in Hounslow
Do you cover Hounslow?
We do. The survey and report are the same in Hounslow as anywhere else.
Does a conservation area affect roof work in Hounslow?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof will not work, we’ll say so before testing.
Can you inspect my roof with a drone?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That’s how we locate breaches you cannot see.
Honest limits
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- Build-ups without a suitable layer below
- Sections we cannot safely access
- Leaks from plumbing or windows
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we’ll give you a straight answer. What our survey covers.
Roof types and parts we check
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
- Green roofs
What happens if roof problems are left?
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. In Hounslow, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.

Rented homes, blocks and businesses
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Useful tips for Hounslow property owners
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Keep foot traffic on flat roofs to a minimum
- Check new waterproofing before handover
- Ask contractors to protect the membrane
- Share any drawings of the roof
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Make sure contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
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 usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In Hounslow, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with what you know about the roof and the leak.
- 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.
- You get a report with photos of each breach.
How to prepare
- Let us know about parking near the property
- Jot down any questions you want answered
- Keep pets in another room
Booking a survey
Every survey is priced before it is booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or use the contact form.
Advice
Different roofs, different checks
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Suitability for ELD depends on the system.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.

Flat and commercial roofs around Hounslow
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. If your home in Hounslow is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Hounslow has a long history of building, with Osterley House about 1.6 miles north. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
As a London address, Hounslow can be tricky for parking: tell us about permits, visitor bays or off-street space when you book, as a space near the door can’t be promised. The streets around a church like Church of St Mary the Virgin are frequently among the oldest in a place, and if your house is among the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Anyone responsible for a site like Chatsworth Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
