Electronic leak detection in Hounslow West: what you get
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey single-ply roofs, roof terraces and balconies and liquid-applied waterproofing, and people most often book us about breaches hidden under paving or planting and holes around roof penetrations.
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 Hounslow West, the roof above may belong to the building rather than one flat.
The report records the flat roof membrane as we found it on the day. It’s useful right away, and a good reference for later, for example when you want to check whether anything has changed.

How we price electronic leak detection
What a survey costs depends on the time and equipment it needs. That comes down to:
- The number of roofs, including extensions and garages
- Roof area
- The type of building, from a house to a block or an office
- Chimneys, valleys, parapets and other details
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Helping us price your survey
A few details help us point you to the right survey and price. When you contact us, tell us:
- Why you want a survey: buying, a leak, a storm or new work
- Your postcode, so we can check access and travel
- Where any leaks, stains or damp patches show inside
- Pictures of the roof from a safe spot, if you have them
Most bookings start with a short call: phone 07833 053749 or use the contact form. You will have a price before anything is arranged.
Rented homes, blocks and businesses
Letting agents can arrange access with tenants, at a time agreed beforehand. Surveys run on weekdays and at weekends, which can make access easier.
Where a roof is shared: we need access agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the survey around it.
What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. From the street, a London terrace usually shows only its front slope or parapet, so in Hounslow West we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Tell us who holds the keys.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Find any records of previous roof work
- Keep pets inside or away from the areas we are looking at
- Unlock side gates and any roof access doors
Arrange a survey
We confirm the price for your survey before you book, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or send us an email.
Advice
When to book a survey in Hounslow West
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.
Typical things we’re asked to look at include:
- Patched roofs that still leak
- Stains far from any visible defect
- Waterproofing to test before it’s covered
- Failed seams and laps
If you let a flat or house near Hounslow station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- Whether the loft is part of the inspection
- Whether you can ask questions once you have the report
- How long they’ve been surveying roofs
- How they plan to inspect the roof safely
Other services in Hounslow West
How the survey changes by roof type
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.

Electronic leak detection in Hounslow West: local notes
Hounslow West has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, frequently have flat roofs. If you look after one, a leak through a flat roof can put a room out of use. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church such as Church of St Paul are frequently among the oldest in a place, and if your house is among the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking. Anyone responsible for a site like Hounslow Heath Infant and Nursery School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
