Electronic leak detection in Eastcote, Greater London
Wondering about the flat roof membrane at a property in Eastcote? You can book electronic leak detection in Eastcote and across Greater London.
- Stains far from any visible defect
- Leaks through a covered membrane
- A flat roof leak that cannot be traced
Why get it checked now?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.
What you get with us
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Covered by professional indemnity and public liability insurance
- 20+ years’ experience
- Independent findings on the roof’s condition

Electronic leak detection in Eastcote: what you get
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 is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. If you’re worried about gaps at membrane joints and punctures from foot traffic or tools, we can find out what’s behind it.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Eastcote shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Practical tips
These tips come from what we see on roofs every week:
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
- Avoid repeated repairs without finding the cause
- Ask contractors to protect the membrane
Questions about the results are welcome. We will explain what was found and what it means.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
Signs you need electronic leak detection in Eastcote
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Typical things we’re asked to look at include:
- Failed seams and laps
- Patched roofs that still leak
- Leaks through a covered membrane
- Punctures from foot traffic or tools
If you live in an older home near St Lawrence, flat-roofed rear additions and dormers added over the years are worth checking.
What to check before booking
- When you’ll get the report
- Whether they hold professional indemnity and public liability insurance
- Whether you get a written report with photos
- Will they check the loft as well as the outside?
Electronic leak detection around Eastcote
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. 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 fill the gaps in between, on extensions, garages, dormers and business premises. With Headstone Manor about 1.7 miles north-east, Eastcote sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you look after a building like Cannon Lane Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Controlled parking zones are common in London, so mention any permit rules for Eastcote, along with any off-street space.
Eastcote is about 1 mile north-east of Ruislip, in Greater London. Bookings from Eastcote are handled just like any other: a call or an email, a price, then a date. Eastcote is one of the towns and villages in Greater London we cover for electronic leak detection. London is in our area too.

Your questions about electronic leak detection in Eastcote
Does a conservation area affect roof work in Eastcote?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you carry out roof surveys in Eastcote?
Yes, Eastcote is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or email us with the address and a few details.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
How long will testing take?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
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’ll discuss it before we quote.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in; we’ll agree the details as you book.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
The survey, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. Surveys in Eastcote can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, 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.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- Leave a clear route to the loft
- Jot down any questions you want answered
Booking a survey
If you are buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.
Advice
What a survey costs
Prices vary from roof to roof, for these reasons:
- The type of building, from a house to a block or an office
- Chimneys, valleys, parapets and other details
- Height and safe access
- Extensions, dormers and garages with roofs of their own
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to let us know when you contact us
A few details help us suggest the right survey and price. When you contact us, let us know:
- Any stains, drips or damp patches you’ve seen indoors
- Any photos you have, taken from ground level or a window
- Anything about access we should know
- What kind of property and roof it is
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or use the contact form.
What electronic leak detection doesn’t cover
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Areas we cannot reach or that can’t be tested
- Repairing the breaches (that is for your roofer)
- Leaks from plumbing or windows
If in doubt, ring 07833 053749 or send us an email and we will suggest the right survey. What a survey covers and doesn’t.
