Electronic leak detection in Yiewsley: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You’ll also know what to check next. Common reasons to book are punctures from foot traffic or tools and leaking laps in the waterproofing, on liquid-applied waterproofing, flat roof membranes and commercial flat roofs.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Yiewsley, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before you book.
What you get with us
- An independent view of the roof
- Drone and thermal imaging surveys available
- Over 20 years’ experience
- Drone flown under a CAA Flyer ID and Operator ID

Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Surveys for landlords and agents in Yiewsley
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or use the contact form.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, so they’re priced to suit.
The survey, step by step
The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. For a visit in Yiewsley, parking and access are the things to plan: 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 loft space and from the roof where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- 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.
Before the survey
- Dig out any old roof reports or invoices
- If it isn’t your property yet, arrange access through the agent
- Point out any leaks or damp patches
Getting a price
We confirm the exact price before booking, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or email us.

What electronic leak detection looks like in Yiewsley
The wider area around Yiewsley has a long history of building, with Ickenham Hall about 3.3 miles north. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like Rabbsfarm Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you live in an older home near St Matthew's, flat-roofed rear additions and dormers added over the years are worth checking. If you run a business near The Chimes, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Yiewsley: your questions answered
Will parking be an issue for a roof survey in Yiewsley?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when booking.
How do I find out if my home in Yiewsley is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We will discuss it before we quote.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
