Electronic leak detection in Acton
There are different ELD methods. Low-voltage methods usually need a wet roof surface and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. If neither method suits your roof, we’ll tell you at the outset. If you’ve noticed holes left by work on the roof and leaks through a covered membrane, we can find out what’s behind it.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Acton, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

How the survey works
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey typically takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. In Acton, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Leave side gates unlocked
- Agree roof access with the managing agent if it is shared
- Gather any invoices or paperwork from past roof work
Getting a price
A quick phone call is normally the easiest start: phone 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
Advice
Useful tips for Acton property owners
You don’t need to be a roofer to help. What helps most:
- Clear flat roof outlets regularly
- Share any drawings of the roof
- Check new waterproofing before handover
- Use boards when working on the roof
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

- Height and safe access
- How big the roof is

What electronic leak detection looks like in Acton
Historic houses such as Gunnersbury Park, about 1.4 miles south-west, show how far back building in the area around Acton goes.

Common questions in Acton
Will parking be an issue for a roof survey in Acton?
It can be, so it helps to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.

I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so the building owner or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
Will you go up on the roof?
Only if it is safe. We check everything that can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. Anything we can’t see is noted in the report.
Is Acton in your area?

Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access as you book.
